+5. Click "Run workflow" to build and deploy your branch to TestPyPI
 
-1. Create a branch in which the development release will live:
-    - Bump the version number in adherence to [Semantic Versioning](http://semver.org/) and [Developmental Release](https://peps.python.org/pep-0440/#developmental-releases) in `slack_bolt/version.py`
-      - Example the current version is `1.2.3` a proper development bump would be `1.3.0.dev0`
-      - `.dev` will indicate to pip that this is a [Development Release](https://peps.python.org/pep-0440/#developmental-releases) 
-      - Note that the `dev` version can be bumped in development releases: `1.3.0.dev0` -> `1.3.0.dev1`
-    - Commit with a message including the new version number. For example `1.3.0.dev0` & Push the commit to a branch where the development release will live (create it if it does not exist)
-      - `git checkout -b future-release`
-      - `git commit -m 'version 1.3.0.dev0'`
-      - `git push future-release`
-    - Create a git tag for the release. For example `git tag v1.3.0.dev0`.
-    - Push the tag up to github with `git push origin --tags`

-3. (Slack Internal) Communicate the release internally
+#### Development Deployment
 
+Deploying a new version of this library to PyPI is triggered by publishing a GitHub Release.
+Before creating a new release, ensure that everything on a stable branch has
+landed, then [run the tests](#run-all-the-unit-tests).
+
+1. Create the commit for the release
+   1. Use the latest supported Python version. Using a [virtual environment](#python-and-friends) is recommended.
+   2. In `slack_bolt/version.py` bump the version number in adherence to [Semantic Versioning](http://semver.org/) and [Developmental Release](https://peps.python.org/pep-0440/#developmental-releases).
+      - Example: if the current version is `1.2.3`, a proper development bump would be `1.2.4.dev0`
+      - `.dev` will indicate to pip that this is a [Development Release](https://peps.python.org/pep-0440/#developmental-releases)
+      - Note that the `dev` version can be bumped in development releases: `1.2.4.dev0` -> `1.2.4.dev1`
+   3. Build the docs with `./scripts/generate_api_docs.sh`.
+   4. Commit with a message including the new version number. For example `1.2.4.dev0` & push the commit to a branch where the development release will live (create it if it does not exist)
+      1. `git checkout -b future-release`
+      2. `git add --all` (review files with `git status` before committing)
+      3. `git commit -m 'chore(release): version 1.2.4.dev0'`
+      4. `git push -u origin future-release`
+2. Create a new GitHub Release
+   1. Navigate to the [Releases page](https://github.com/slackapi/bolt-python/releases).
+   2. Click the "Draft a new release" button.
+   3. Set the "Target" to the feature branch with the development changes.
+   4. Click "Tag: Select tag"
+   5. Input a new tag name manually. The tag name must match the version in `slack_bolt/version.py` prefixed with "v" (e.g., if version is `1.2.4.dev0`, enter `v1.2.4.dev0`)
+   6. Click the "Create a new tag" button. This won't create your tag immediately.
+   7. Click the "Generate release notes" button.
+   8. The release name should match the tag name!
+   9. Edit the resulting notes to ensure they have decent messaging that is understandable by non-contributors, but each commit should still have its own line.
+   10. Set this release as a pre-release.
+   11. Publish the release by clicking the "Publish release" button!
+3. Navigate to the [release workflow run](https://github.com/slackapi/bolt-python/actions/workflows/pypi-release.yml). You will need to approve the deployment!
+4. After a few minutes, the corresponding version will be available on <https://pypi.org/project/slack-bolt>.

 #### Production Deployment
 
-1. Create the commit for the release: 
-   - Bump the version number in adherence to [Semantic Versioning](http://semver.org/) in `slack_bolt/version.py`

+
+## Project Overview
+
+Slack Bolt for Python -- a framework for building Slack apps in Python.
+
+- **Foundation:** Built on top of `slack_sdk` (see `pyproject.toml` constraints).
+- **Execution Models:** Supports both synchronous (`App`) and asynchronous (`AsyncApp` using `asyncio`) execution. Async mode requires `aiohttp` as an additional dependency.
+- **Framework Adapters:** Features built-in adapters for web frameworks (Flask, FastAPI, Django, Tornado, Pyramid, and many more) and serverless environments (AWS Lambda, Google Cloud Functions).
+- **Python Version:** Requires Python 3.7+ as defined in `pyproject.toml`.
+
+- **Repository**: <https://github.com/slackapi/bolt-python>
+- **Documentation**: <https://docs.slack.dev/tools/bolt-python/>
+- **PyPI**: <https://pypi.org/project/slack-bolt/>
+- **Current version**: defined in `slack_bolt/version.py` (referenced by `pyproject.toml` via `[tool.setuptools.dynamic]`)
+
+## Environment Setup
+
+You can verify the venv is active by checking `echo $VIRTUAL_ENV`. If tools like `black`, `flake8`, `mypy` or `pytest` are not found, ask the user to activate the venv.
+
+A python virtual environment (`venv`) should be activated before running any commands.
+
+```bash
+# Create a venv (first time only)
+python -m venv .venv
+
+# Activate
+source .venv/bin/activate
+
+# Install all dependencies
+./scripts/install.sh
+```
+
+## Common Commands
+
+### Pre-submission Checklist
+
+Before considering any work complete, you MUST run these commands in order and confirm they all pass:
+
+```bash
+./scripts/format.sh --no-install     # 1. Format
+./scripts/lint.sh --no-install        # 2. Lint
+./scripts/run_tests.sh <relevant>     # 3. Run relevant tests (see Testing below)
+./scripts/run_mypy.sh --no-install    # 4. Type check
+```
+
+To run everything at once (installs deps + formats + lints + tests + typechecks):
+
+```bash
+./scripts/install_all_and_run_tests.sh
+```
+
+### Testing
+
+Always use the project scripts instead of calling `pytest` directly:
+
+```bash
+# Run a single test file
+./scripts/run_tests.sh tests/scenario_tests/test_app.py
+
+# Run a single test function
+./scripts/run_tests.sh tests/scenario_tests/test_app.py::TestApp::test_name
+```
+
+### Formatting, Linting, Type Checking
+
+```bash
+# Format -- Black, configured in pyproject.toml
+./scripts/format.sh --no-install
+
+# Lint -- Flake8, configured in .flake8
+./scripts/lint.sh --no-install
+
+# Type check -- mypy, configured in pyproject.toml
+./scripts/run_mypy.sh --no-install
+```
+
+## Critical Conventions
+
+### Sync/Async Mirroring Rule
+
+**When modifying any sync module, you MUST also update the corresponding async module (and vice versa).** This is the most important convention in this codebase.
+
+Almost every module has both a sync and async variant. Async files use the `async_` prefix alongside their sync counterpart:
+
+```text
+slack_bolt/middleware/custom_middleware.py          # sync
+slack_bolt/middleware/async_custom_middleware.py    # async
+
+slack_bolt/context/say/say.py                      # sync
+slack_bolt/context/say/async_say.py                # async
+
+slack_bolt/listener/custom_listener.py              # sync
+slack_bolt/listener/async_listener.py              # async
+```
+
+**Modules that come in sync/async pairs:**
+
+- `slack_bolt/app/` -- `app.py` / `async_app.py`
+- `slack_bolt/middleware/` -- every middleware has an `async_` counterpart
+- `slack_bolt/listener/` -- `listener.py` / `async_listener.py`, plus error/completion/start handlers
+- `slack_bolt/listener_matcher/` -- `builtins.py` / `async_builtins.py`
+- `slack_bolt/context/` -- each subdirectory (e.g., `say/`, `ack/`, `respond/`) has `async_` variants
+- `slack_bolt/kwargs_injection/` -- `args.py` / `async_args.py`, `utils.py` / `async_utils.py`
+
+**Adapters are an exception:** Most adapters are sync-only or async-only depending on the framework. Async-native frameworks (FastAPI, Starlette, Sanic, Tornado, ASGI, Socket Mode) have `async_handler.py`. Sync-only frameworks (Flask, Django, Bottle, CherryPy, Falcon, Pyramid, AWS Lambda, Google Cloud Functions, WSGI) have `handler.py`.
+
+### Prefer the Middleware Pattern
+
+Middleware is the project's preferred approach for cross-cutting concerns. Before adding logic to individual listeners or utility functions, consider whether it belongs as a built-in middleware in the framework.
+
+**When to add built-in middleware:**
+
+- Cross-cutting concerns that apply to many or all requests (logging, metrics, observability)
+- Request validation, transformation, or enrichment
+- Authorization extensions beyond the built-in `SingleTeamAuthorization`/`MultiTeamsAuthorization`
+- Feature-level request handling (the `Assistant` middleware in `slack_bolt/middleware/assistant/assistant.py` is the canonical example -- it intercepts assistant thread events and dispatches them to registered sub-listeners)
+
+**How to add built-in middleware:**
+
+1. Subclass `Middleware` (sync) and implement `process(self, *, req, resp, next)`. Call `next()` to continue the chain.
+2. Subclass `AsyncMiddleware` (async) and implement `async_process(self, *, req, resp, next)`. Call `await next()` to continue.
+3. Export from `slack_bolt/middleware/__init__.py` (sync) and `slack_bolt/middleware/async_builtins.py` (async).
+4. Register the middleware in `App.__init__()` (`slack_bolt/app/app.py`) and `AsyncApp.__init__()` (`slack_bolt/app/async_app.py`) where the default middleware chain is assembled.
+
+**Canonical example:** `AttachingFunctionToken` (`slack_bolt/middleware/attaching_function_token/`) is a good small middleware to follow -- it has a clean sync/async pair, a focused `process()` method, and is properly exported and registered in the app's middleware chain.
+
+### Single Runtime Dependency Rule
+
+The core package depends ONLY on `slack_sdk` (defined in `pyproject.toml`). Never add runtime dependencies to `pyproject.toml`. Additional dependencies go in the appropriate `requirements/*.txt` file.
+
+## Architecture
+
+### Request Processing Pipeline
+
+Incoming requests flow through a middleware chain before reaching listeners:
+
+1. **SSL Check** -> **Request Verification** (signature) -> **URL Verification** -> **Authorization** (token injection) -> **Ignoring Self Events** -> Custom middleware
+2. **Listener Matching** -- `ListenerMatcher` implementations check if a listener should handle the request
+3. **Listener Execution** -- listener-specific middleware runs, then `ack()` is called, then the handler executes
+
+For FaaS environments (`process_before_response=True`), long-running handlers execute as "lazy listeners" in a thread pool after the ack response is returned.
+
+### Core Abstractions
+
+- **`App` / `AsyncApp`** (`slack_bolt/app/`) -- Central class. Registers listeners via decorators (`@app.event()`, `@app.action()`, `@app.command()`, `@app.message()`, `@app.view()`, `@app.shortcut()`, `@app.options()`, `@app.function()`). Dispatches incoming requests through middleware to matching listeners.
+- **`Middleware`** (`slack_bolt/middleware/`) -- Abstract base with `process(req, resp, next)`. Built-in: authorization, request verification, SSL check, URL verification, assistant, self-event ignoring.
+- **`Listener`** (`slack_bolt/listener/`) -- Has matchers, middleware, and an ack/handler function. `CustomListener` is the main implementation.
+- **`ListenerMatcher`** (`slack_bolt/listener_matcher/`) -- Determines if a listener handles a given request. Built-in matchers for events, actions, commands, messages (regex), shortcuts, views, options, functions.
+- **`BoltContext`** (`slack_bolt/context/`) -- Dict-like object passed to listeners with `client`, `say()`, `ack()`, `respond()`, `complete()`, `fail()`, plus event metadata (`user_id`, `channel_id`, `team_id`, etc.).
+- **`BoltRequest` / `BoltResponse`** (`slack_bolt/request/`, `slack_bolt/response/`) -- Request/response wrappers. Request has `mode` of "http" or "socket_mode".
+
+### Kwargs Injection
+
+Listeners receive arguments by parameter name. The framework inspects function signatures and injects matching args: `body`, `event`, `action`, `command`, `payload`, `context`, `client`, `ack`, `say`, `respond`, `logger`, `complete`, `fail`, etc. Defined in `slack_bolt/kwargs_injection/args.py`.
+
+### Adapter System
+
+Each adapter in `slack_bolt/adapter/` converts between a web framework's request/response types and `BoltRequest`/`BoltResponse`. Adapters exist for: Flask, FastAPI, Django, Starlette, Sanic, Bottle, Tornado, CherryPy, Falcon, Pyramid, AWS Lambda, Google Cloud Functions, Socket Mode, WSGI, ASGI, and more.
+
+### AI Agents & Assistants
+
+`Assistant` middleware (`slack_bolt/middleware/assistant/`) handles assistant thread events.
+
+## Key Development Patterns
+
+### Adding a Context Utility
+
+Each context utility lives in its own subdirectory under `slack_bolt/context/`:
+
+```text
+slack_bolt/context/my_util/
+    __init__.py
+    my_util.py          # sync implementation
+    async_my_util.py    # async implementation
+    internals.py        # shared logic (optional)
+```
+
+Then wire it into `BoltContext` (`slack_bolt/context/context.py`) and `AsyncBoltContext` (`slack_bolt/context/async_context.py`).
+
+### Adding a New Adapter
+
+1. Create `slack_bolt/adapter/<framework>/`
+2. Add `__init__.py` and `handler.py` (or `async_handler.py` for async frameworks)
+3. The handler converts the framework's request to `BoltRequest`, calls `app.dispatch()`, and converts `BoltResponse` back
+4. Add the framework to `requirements/adapter.txt` with version constraints
+5. Add adapter tests in `tests/adapter_tests/` (sync) or `tests/adapter_tests_async/` (async)
+
+### Adding a Kwargs-Injectable Argument
+
+1. Add the new arg to `slack_bolt/kwargs_injection/args.py` and `async_args.py`
+2. Update the `Args` class with the new property
+3. Populate the arg in the appropriate context or listener setup code
+
+## Security Considerations
+
+- **Request Verification:** The built-in `RequestVerification` middleware validates `x-slack-signature` and `x-slack-request-timestamp` on every incoming HTTP request. Never disable this in production. It is automatically skipped for `socket_mode` requests.
+- **Tokens & Secrets:** `SLACK_SIGNING_SECRET` and `SLACK_BOT_TOKEN` must come from environment variables. Never hardcode or commit secrets.
+- **Authorization Middleware:** `SingleTeamAuthorization` and `MultiTeamsAuthorization` verify tokens and inject an authorized `WebClient` into the context. Do not bypass these.
+- **Tests:** Always use mock servers (`tests/mock_web_api_server/`) and dummy values. Never use real tokens in tests.
+
+## Dependencies
+
+The core package has a **single required runtime dependency**: `slack_sdk` (defined in `pyproject.toml`). Do not add runtime dependencies.
+
+**`requirements/` directory structure:**
+
+- `async.txt` -- async runtime deps (`aiohttp`, `websockets`)
+- `adapter.txt` -- all framework adapter deps (Flask, Django, FastAPI, etc.)
+- `testing.txt` -- test runner deps (`pytest`, `pytest-asyncio`, includes `async.txt`)
+- `testing_without_asyncio.txt` -- test deps without async (`pytest`, `pytest-cov`)
+- `adapter_testing.txt` -- adapter-specific test deps (`moto`, `boddle`, `sanic-testing`)
+- `tools.txt` -- dev tools (`mypy`, `flake8`, `black`)
+
+When adding a new dependency: add it to the appropriate `requirements/*.txt` file with version constraints, never to `pyproject.toml` `dependencies` (unless it's a core runtime dep, which is very rare).
+
+## Test Organization and CI
+
+### Directory Structure
+
+- `tests/scenario_tests/` -- Integration-style tests with realistic Slack payloads
+- `tests/slack_bolt/` -- Unit tests mirroring the source structure
+- `tests/adapter_tests/` and `tests/adapter_tests_async/` -- Framework adapter tests
+- `tests/mock_web_api_server/` -- Mock Slack API server used by tests
+- Async test variants use `_async` suffix directories
+
+**Where to put new tests:** Mirror the source structure. For `slack_bolt/middleware/foo.py`, add tests in `tests/slack_bolt/middleware/test_foo.py`. For async variants, use the `_async` suffix directory or file naming pattern. Adapter tests go in `tests/adapter_tests/` (sync) or `tests/adapter_tests_async/` (async).
+
+**Mock server:** Many tests use `tests/mock_web_api_server/` to simulate Slack API responses. Look at existing tests for usage patterns rather than making real API calls.
+
+### CI Pipeline
+
+GitHub Actions (`.github/workflows/ci-build.yml`) runs on every push to `main` and every PR:
+
+- **Lint** -- `./scripts/lint.sh` on latest Python
+- **Typecheck** -- `./scripts/run_mypy.sh` on latest Python
+- **Unit tests** -- full test suite across Python 3.7--3.14 matrix
+- **Code coverage** -- uploaded to Codecov
+
+## PR and Commit Guidelines
+
+- PRs target the `main` branch
+- You MUST run `./scripts/install_all_and_run_tests.sh` before submitting
+- PR template (`.github/pull_request_template.md`) requires: Summary, Testing steps, Category checkboxes (`App`, `AsyncApp`, Adapters, Docs, Others)
+- Requirements: CLA signed, test suite passes, code review approval
+- Commits should be atomic with descriptive messages. Reference related issue numbers.

-There are two main ways to respond to actions. The first (and most common) way is to use `say()`, which sends a message back to the conversation where the incoming request took place.

-Since `respond()` is a utility for calling the `response_url`, it behaves in the same way. You can pass [all the message payload properties](https://api.slack.com/reference/messaging/payload) as keyword arguments along with optional properties like `response_type` (which has a value of `"in_channel"` or `"ephemeral"`), `replace_original`, `delete_original`, `unfurl_links`, and `unfurl_media`. With that, your app can send a new message payload that will be published back to the source of the original interaction.

-
-<div class="section-content">
-This guide will cover how to get started with your next-gen platform using Bolt for Python, by setting up the Slack CLI and installing the required dependencies.
-
-Find out about the next-generation platform on Slack's <a href="https://api.slack.com/future/intro" target="_blank">official introduction page.</a>
-</div>
-
----
-
-### Limitations
-
-Bolt for Python supports app development using next-gen platform features like <a href="/bolt-python/future/concepts#functions" target="_blank">Functions</a>, <a href="/bolt-python/future/concepts#manifest-workflows" target="_blank">Workflows</a> and tools such as the Slack CLI alongside all current generally available Slack Platform features.
-
-#### We do not yet support
-
-- Deployment to secure and managed Slack infrastructure.
-- Datastores API <a href="https://api.slack.com/future/datastores" target="_blank">Datastores</a> functionality.
-
-> 💡 If you'd like to deploy your app with Slack infrastructure, consider building your next-generation application with the Deno Slack API. You can get started with that <a href="https://api.slack.com/future/get-started" target="_blank">here</a>.
-
----
-
-### Setting up {#setting-up}
-
-#### Slack CLI {#setting-up-cli}
-
-To build a next-generation app with Bolt for Python, you'll need to get the Slack CLI.
-
-Install the Slack CLI by following this <a href="https://api.slack.com/future/quickstart" target="_blank">Quickstart</a>. Since we won't be using Deno to build our next-generation app, you can skip any instructions related to installing Deno or creating an app using a Deno template. Once you've logged into the CLI using `slack login` and verified your login using `slack auth list`, you can proceed with the instructions in this guide.
-
-#### Dependencies {#setting-up-dependencies}
-
-Once the CLI is set up, make sure your machine has the most recent version of <a href="https://www.python.org/" target="_blank">Python</a> installed. You can install Python through a package manager (such as <a href="https://brew.sh/" target="_blank">Homebrew</a> for macOS) or directly from the <a href="https://www.python.org/downloads/" target="_blank">website</a>.
-
----
-
-### Create a new app {#create-app}
-
-Before you start developing with Bolt, you'll want to create a Slack app.
-
-To create the app, you'll run the following command:
-
-```bash
-slack create my-app -t slack-samples/bolt-python-starter-template -b future
-```
-
-This command creates an app through the CLI by cloning a specified template. In this case, the template is the <a href="https://github.com/slack-samples/bolt-python-starter-template/tree/future" target="_blank">Bolt for Python Starter Template</a> on the `future` branch. This starter template includes a "Hello World" example that demonstrates how to use <a href="/bolt-python/future/concepts#built-in-functions" target="_blank">built-in</a> and <a href="/bolt-python/future/concepts#functions" target="_blank">custom</a> Functions, <a href="https://api.slack.com/future/triggers" target="_blank">Triggers</a> and <a href="/bolt-python/future/concepts#manifest-workflows" target="_blank">Workflows</a>.
-
-Once the app is successfully created, you should see a message like this:
-
-```text
-✨ my-app successfully created
-
-🧭 Explore your project's README.md for documentation and code samples, and at any time run slack help to display a list of available commands
-
-🧑‍🚀 Follow the steps below to try out your new project
-
-1️⃣  Change into your project directory with: cd my-app
-
-2️⃣  Develop locally and see changes in real-time with: slack run
-
-3️⃣  When you're ready to deploy for production use: slack deploy
-
-🔔 If you leave the workspace, you won’t be able to manage any apps you’ve deployed to it. Apps you deploy will belong to the workspace even if you leave the workspace
-```
-
----
-
-### Set up your trigger {#setup-trigger}
-
-As mentioned, this app comes with pre-existing functionality - it uses Functions, Workflows and a <a href="https://api.slack.com/future/triggers/link" target="_blank">Link Trigger</a> that will allow users in Slack to initiate the functionality provided by the app. Let's run a command to initialize that Link Trigger via the CLI.
-
-First, make sure you're in the project directory in your command line: `cd my-app`
-
-Then, run the following command to create a Trigger:
-
-```bash
-slack triggers create --trigger-def "triggers/sample-trigger.json"      
-```
-
-The above command will create a <a href="https://api.slack.com/future/triggers/link" target="_blank">Link Trigger</a> for the selected workspace. Make sure to select the workspace you want. Once the trigger is successfully created, you should see an output like this:
-
-```bash
-⚡ Trigger created
-   Trigger ID:   [ID]
-   Trigger Type: shortcut
-   Trigger Name: Sample Trigger
-   URL: https://slack.com/shortcuts/[ID]/[Some ID]
-```
-
-The provided URL can be pasted into Slack; Slack will unfurl it into a button that users can interact with to initiate your app's functionality! Copy this URL and save it somewhere; you'll need it for later.
-
----
-
-### Run your app {#run-your-app}
-
-Now that your app and Trigger are successfully created, let's try running it!
-
-```bash
-# install the required project dependencies
-pip install -r requirements.txt
-
-# start a local development server
-slack run
-```
-
-Executing `pip install -r requirements.txt` installs all the project requirements to your machine.
-
-Executing `slack run` starts a local development server, syncing changes to your workspace's development version of your app.
-
-You'll be prompted to select a workspace to install the app to&mdash;select the development instance of your workspace (you'll know it's the development version because the name has the string `(dev)` appended).
-
-> 💡 If you don't see the workspace you'd like to use in the list, you can `CTRL + C` out of the `slack run` command and run `slack auth login`. This will allow you to authenticate in your desired workspace to have it show up in the list for `slack run`.
-
-You'll see an output in your Terminal to indicate your app is running, similar to what you would see with any other Bolt for Python app. You can search for the `⚡️ Bolt app is running! ⚡️` message to make sure that your app has successfully started up.
-
-### Trigger your app's workflow {#trigger-workflow}
-
-With your app running, access your workspace and paste the URL from the Trigger you created in the [previous step](/bolt-python/tutorial/getting-started-future#setup-trigger) into a message in a public channel.
-
-> 💡 App Triggers are automatically saved as a channel bookmark under "Workflows" for easy access.
-
-Send the message and click the "Run" button that appears. A modal will appear prompting you to enter information to greet someone in your Slack workspace. Fill out the requested information.
-
-![Hello World modal](https://slack.dev/bolt-js/assets/hello-world-modal.png "Hello World modal")
-
-Then, submit the form. In the specified channel submitted in the form, you should receive a message from the app tagging the submitted user. The message will also contain a randomly generated greeting and the message you wrote in the form.
-
-The full app flow can be seen here:
-![Hello World app](https://slack.dev/bolt-js/assets/hello-world-demo.gif "Hello World app")
-
----
-
-### Next steps {#next-steps}
-
-Now we have a working instance of a next-generation app in your workspace and you've seen it in action! You can explore on your own and dive into the code yourself <a href="https://github.com/slack-samples/bolt-python-starter-template/tree/future" target="_blank">here</a> or continue your learning journey by diving into [App Manifests](/bolt-python/future/concepts#manifests) or looking into adding more [Functions](/bolt-python/future/concepts#functions), [Workflows](/bolt-python/future/concepts#manifest-workflows), and [Triggers](#setup-trigger) to your app!

-Your app can use the `function()` method to listen to incoming function requests. The method requires a function `callback_id` of type `str`. This `callback_id` must also be defined in your [Function](/bolt-python/future/concepts#manifest-functions) definition. Functions must eventually be completed with the `complete()` function to inform Slack that your app has processed the function request. `complete()` requires **one of two** keyword arguments: `outputs` or `error`. There are two ways to complete a Function with `complete()`:
-
-* `outputs` of type `dict` completes your function **successfully** and provides a dictionary containing the outputs of your function as defined in the app's manifest.
-* `error` of type `str` completes your function **unsuccessfully** and provides a message containing information regarding why your function was not successful.

-The `function()` method returns a `SlackFunction` decorator object. This object can be used by your app to set up interactive listeners such as [actions](/bolt-python/concepts#action-respond) and [views](/bolt-python/concepts#view_submissions). These listeners listen to events created during the handling of your `function` event. Additionally, they will only be called when a user interacts with a block element that has the following attributes:
-
-* It was created during the handling of a `function` event.
-* The `action_id` matches the interactive listeners `action_id`.
-
-These listeners behave similarly to the ones assigned directly to your app. The notable difference is that `complete()` must be called once your function is completed.

-
-Your project should contain a `manifest.json` file that defines your app's manifest. This is where you'll configure your application name and scopes, declare the functions your app will use, and more.
-Refer to the <a href="https://api.slack.com/reference/manifests" target="_blank">App Manifest</a> and <a href="https://api.slack.com/future/manifest#manifest-properties" target="_blank">Manifest Property</a> documentation to learn
-about the available manifest configurations.
-
-Notably, the App Manifest informs Slack of the definitions for:
-
-* [Functions](/bolt-python/future/concepts#manifest-functions)
-* [Workflows](/bolt-python/future/concepts#manifest-workflows)
-
-`manifest.json` is located at the top level of <a href="https://github.com/slack-samples/bolt-python-starter-template/tree/future" target="_blank">our example projects</a>, along with a `triggers` folder containing
-`*_trigger.json` files that define the <a href="https://api.slack.com/future/triggers" target="_blank">triggers</a>
-for your app.

-
-#### Linting, prediction & validation
-
-Syntax and formatting checks are required to efficiently edit your `manifest.json`. Multiple IDEs are able to support
-this, namely: <a href="https://code.visualstudio.com/docs/languages/json#_mapping-in-the-json" target="_blank">Visual Studio Code</a>, <a href="https://www.jetbrains.com/help/pycharm/json.html#ws_json_schema_add_custom" target="_blank">Pycharm</a>, <a href="https://www.sublimetext.com/" target="_blank">Sublime Text</a> (via <a href="https://packagecontrol.io/packages/LSP-json" target="_blank">LSP-json</a>) and many more.
-
-To get **manifest prediction & validation** in your IDE, include the following line in your `manifest.json` file:
-
-```json
-{
-  "$schema": "https://raw.githubusercontent.com/slackapi/manifest-schema/main/manifest.schema.json",
-  ...
-}
-```
-
-Using the <a href="https://api.slack.com/future/tools/cli/commands" target="_blank">Slack CLI</a> you can validate your `manifest.json` against the Slack API with:
-
-```bash
-slack manifest validate
-```

-## Setup an existing app <span class="label-beta">BETA</span>
-
-<div class="section-content">
-If you would like to setup an existing Slack app written with the beta tools from the <a href="https://api.slack.com/future/intro" target="_blank">next-generation platform</a>, this guide is for you!
-</div>
-
-To get started with a new Bolt for Python application take a look at this [Getting Started guide](/bolt-python/tutorial/getting-started-future) instead.
-
----
-
-### Prerequisites {#prerequisites}
-
-Before we get started, make sure you've followed the [Setting Up step](/bolt-python/tutorial/getting-started-future#setting-up) of the [Getting Started guide](/bolt-python/tutorial/getting-started-future) to install required dependencies.
-
----
-
-### Set up your app to work with the Slack CLI {#setup-with-cli}
-
-Update your project's version of Bolt (sometimes found in <code><a href="https://pip.pypa.io/en/latest/user_guide/#requirements-files" target="_blank">requirements.txt</a></code>) to the latest `*.dev*` <a href="https://pypi.org/project/slack-bolt/#history" target="_blank">distribution</a> and reinstall your dependencies: `pip install -r requirements.txt`
-
-```text
-# with pip
-pip install slack-bolt==*.dev*
-
-# in requirements.txt
-slack-bolt==*.dev*
-```
-
-Then, add a `slack.json` file to your local project root containing the contents of our [template slack.json](https://github.com/slack-samples/bolt-python-starter-template/blob/future/slack.json).
-
----
-
-### Add your manifest {#manifest-in-code}
-
-Head to [your app's App Config Page](https://api.slack.com/apps) and navigate to Features > App Manifest. Download a copy of your app manifest in the JSON file format.
-
-Add this `manifest.json` to your project root. This represents your project's existing configuration. To get **manifest prediction & validation** in your IDE, include the following line in your `manifest.json` file:
-
-```json
-{
-  "$schema": "https://raw.githubusercontent.com/slackapi/manifest-schema/main/manifest.schema.json",
-  ...
-}
-```
-
-To learn more about the `manifest.json` take a look at the [Manifest concept](/bolt-python/future/concepts#manifest).
-
----
-
-Now let's run the Slack CLI command `slack manifest` to generate your manifest. It should contain at least these settings:
-
-```bash
-{
-  "_metadata": {
-    "major_version": 2
-  },
-  "oauth_config": {
-    "token_management_enabled": true  
-  },
-  "settings": {
-    "interactivity": {
-      "is_enabled": true
-    } 
-  },
-  "org_deploy_enabled": true       
-}
-```
-
-You can also run this command to validate your App's configuration with the Slack API:
-
-```bash
-slack manifest validate
-```
-
----
-
-### Run your app! {#tada}
-
-Run the Slack CLI command `slack run` to start your app in local development.
-
-The CLI will create and install a new development app for you with its own App ID, allowing you to keep your testing changes separate from your production App).
-
-Now you're ready to start adding [Functions](/bolt-python/future/concepts#functions) and [Workflows](/bolt-python/future/concepts#manifest-workflows) to your app!
-
----
-
-### Updating your app configuration {#update-app}
-
-You have probably made changes to your app’s manifest (adding a Function or a Workflow, for example). To sync your production app’s configuration with the changes you’ve made locally in your manifest:
-
-1. Authenticate the Slack CLI with your desired production workspace using `slack login`.
-2. In your project, head over to `./slack/apps.json` and make sure an entry exists for your workspace with the current `app_id` and `team_id` of the workspace.
-
-    ```bash
-    {
-      "apps": {
-        "<your-workspace-name>": {
-          "name": "<your-workspace-name>",
-          "app_id": "A041G4M3U00",
-          "team_id": "T038J6TH5PF"
-        }
-      },
-      "default": "<your-workspace-name>"
-    }
-    ```
-
-3. Run `slack install` and select your app. Select your workspace from the list prompt to install.
-
----
-
-### Conclusion {#conclusion}
-
-Congratulations on migrating your app to the next-generation Slack Platform! 🎉 You can continue your journey by learning about [Manifests](/bolt-python/future/concepts#manifest) or looking into adding [Functions](/bolt-python/future/concepts#functions) and [Workflows](/bolt-python/future/concepts#manifest-workflows) to your app!

-When a builder adds (or later edits) your step in their workflow, your app will receive a [`workflow_step_edit` event](https://api.slack.com/reference/workflows/workflow_step_edit). The `edit` callback in your `WorkflowStep` configuration will be run when this event is received.
-
-Whether a builder is adding or editing a step, you need to send them a [workflow step configuration modal](https://api.slack.com/reference/workflows/configuration-view). This modal is where step-specific settings are chosen, and it has more restrictions than typical modals—most notably, it cannot include `title`, `submit`, or `close` properties. By default, the configuration modal's `callback_id` will be the same as the workflow step.
-
-Within the `edit` callback, the `configure()` utility can be used to easily open your step's configuration modal by passing in the view's blocks with the corresponding `blocks` argument. To disable saving the configuration before certain conditions are met, you can also pass in `submit_disabled` with a value of `True`.
-
-To learn more about opening configuration modals, [read the documentation](https://api.slack.com/workflows/steps#handle_config_view).

-
-To create a workflow step, Bolt provides the `WorkflowStep` class.
-
-When instantiating a new `WorkflowStep`, pass in the step's `callback_id` and a configuration object.
-
-The configuration object contains three keys: `edit`, `save`, and `execute`. Each of these keys must be a single callback or a list of callbacks. All callbacks have access to a `step` object that contains information about the workflow step event.
-
-After instantiating a `WorkflowStep`, you can pass it into `app.step()`. Behind the scenes, your app will listen and respond to the workflow step’s events using the callbacks provided in the configuration object.
-
-Alternatively, workflow steps can also be created using the `WorkflowStepBuilder` class alongside a decorator pattern. For more information, including an example of this approach, [refer to the documentation](https://slack.dev/bolt-python/api-docs/slack_bolt/workflows/step/step.html#slack_bolt.workflows.step.step.WorkflowStepBuilder).

-Using the `inputs` from the `save` callback, this is where you can make third-party API calls, save information to a database, update the user's Home tab, or decide the outputs that will be available to subsequent workflow steps by mapping values to the `outputs` object.

-作成したワークフローステップがワークフローに追加またはその設定を変更されるタイミングで、[`workflow_step_edit` イベントがアプリに送信されます](https://api.slack.com/reference/workflows/workflow_step_edit)。このイベントがアプリに届くと、`WorkflowStep` で設定した `edit` コールバックが実行されます。
-
-ステップの追加と編集のどちらが行われるときも、[ワークフローステップの設定モーダル](https://api.slack.com/reference/workflows/configuration-view)をビルダーに送信する必要があります。このモーダルは、そのステップ独自の設定を選択するための場所です。通常のモーダルより制限が強く、例えば `title`、`submit`、`close` のプロパティを含めることができません。設定モーダルの `callback_id` は、デフォルトではワークフローステップと同じものになります。
-
-`edit` コールバック内で `configure()` ユーティリティを使用すると、対応する `blocks` 引数にビューのblocks 部分だけを渡して、ステップの設定モーダルを簡単に表示させることができます。必要な入力内容が揃うまで設定の保存を無効にするには、`True` の値をセットした `submit_disabled` を渡します。
-
-設定モーダルの開き方に関する詳細は、[こちらのドキュメント](https://api.slack.com/workflows/steps#handle_config_view)を参照してください。

-ワークフローステップの作成には、Bolt が提供する `WorkflowStep` クラスを利用します。
-
-ステップの `callback_id` と設定オブジェクトを指定して、`WorkflowStep` の新しいインスタンスを作成します。
-
-設定オブジェクトは、`edit`、`save`、`execute` という 3 つのキーを持ちます。それぞれのキーは、単一のコールバック、またはコールバックのリストである必要があります。すべてのコールバックは、ワークフローステップのイベントに関する情報を保持する `step` オブジェクトにアクセスできます。
-
-`WorkflowStep` のインスタンスを作成したら、それを`app.step()` メソッドに渡します。これによって、アプリがワークフローステップのイベントをリッスンし、設定オブジェクトで指定されたコールバックを使ってそれに応答できるようになります。
-
-また、デコレーターとして利用できる `WorkflowStepBuilder` クラスを使ってワークフローステップを定義することもできます。 詳細は、[こちらのドキュメント](https://slack.dev/bolt-python/api-docs/slack_bolt/workflows/step/step.html#slack_bolt.workflows.step.step.WorkflowStepBuilder)のコード例などを参考にしてください。

-# Getting started with Bolt for Python
-
-<div class="section-content">
-This guide is meant to walk you through getting up and running with a Slack app using Bolt for Python. Along the way, we’ll create a new Slack app, set up your local environment, and develop an app that listens and responds to messages from a Slack workspace.
-</div>
-
-When you're finished, you'll have this ⚡️[Getting Started with Slack app](https://github.com/slackapi/bolt-python/tree/main/examples/getting_started) to run, modify, and make your own.
-
-> 💡 For this guide, we are going to be using [Socket Mode](https://api.slack.com/apis/connections/socket), our recommended option for those just getting started and building something for their team. If you already know you're going to want to use HTTP as your app's communication protocol, head over to our parallel guide, [Getting Started over HTTP](/bolt-python/tutorial/getting-started-http). 
- 
----
-
-### Create an app {#create-an-app}
-First thing's first: before you start developing with Bolt, you'll want to [create a Slack app](https://api.slack.com/apps/new).
-
-> 💡 We recommend using a workspace where you won't disrupt real work getting done — [you can create a new one for free](https://slack.com/get-started#create).
-
-After you fill out an app name (_you can change it later_) and pick a workspace to install it to, hit the `Create App` button and you'll land on your app's **Basic Information** page.
-
-This page contains an overview of your app in addition to important credentials you'll want to reference later. 
-
-![Basic Information page](../assets/basic-information-page.png "Basic Information page")
-
-Look around, add an app icon and description, and then let's start configuring your app 🔩
-
----
-
-### Tokens and installing apps {#tokens-and-installing-apps}
-Slack apps use [OAuth to manage access to Slack's APIs](https://api.slack.com/docs/oauth). When an app is installed, you'll receive a token that the app can use to call API methods.
-
-There are three main token types available to a Slack app: user (`xoxp`), bot (`xoxb`), and app-level (`xapp`) tokens. 
-- [User tokens](https://api.slack.com/authentication/token-types#user) allow you to call API methods on behalf of users after they install or authenticate the app. There may be several user tokens for a single workspace. 
-- [Bot tokens](https://api.slack.com/authentication/token-types#bot) are associated with bot users, and are only granted once in a workspace where someone installs the app. The bot token your app uses will be the same no matter which user performed the installation. Bot tokens are the token type that _most_ apps use.
-- [App-level tokens](https://api.slack.com/authentication/token-types#app) represent your app across organizations, including installations by all individual users on all workspaces in a given organization and are commonly used for creating WebSocket connections to your app.
-
-We're going to use bot and app-level tokens for this guide.
-
-1. Navigate to the **OAuth & Permissions** on the left sidebar and scroll down to the **Bot Token Scopes** section. Click **Add an OAuth Scope**.
-
-2. For now, we'll just add one scope: [`chat:write`](https://api.slack.com/scopes/chat:write). This grants your app the permission to post messages in channels it's a member of.
-
-3. Scroll up to the top of the **OAuth & Permissions** page and click **Install App to Workspace**. You'll be led through Slack's OAuth UI, where you should allow your app to be installed to your development workspace.
-
-4. Once you authorize the installation, you'll land on the **OAuth & Permissions** page and see a **Bot User OAuth Access Token**. 
-
-![OAuth Tokens](../assets/bot-token.png "Bot OAuth Token")
-
-5. Then head over to **Basic Information** and scroll down under the App Token section and click **Generate Token and Scopes** to generate an app-level token. Add the `connections:write` scope to this token and save the generated `xapp` token, we'll use both these tokens in just a moment. 
-
-6. Navigate to **Socket Mode** on the left side menu and toggle to enable. 
-
-
-> 💡 Treat your tokens like passwords and [keep them safe](https://api.slack.com/docs/oauth-safety). Your app uses tokens to post and retrieve information from Slack workspaces.
-
----
-
-### Setting up your project {#setting-up-your-project}
-With the initial configuration handled, it's time to set up a new Bolt project. This is where you'll write the code that handles the logic for your app.
-
-If you don’t already have a project, let’s create a new one. Create an empty directory:
-
-```shell
-mkdir first-bolt-app
-cd first-bolt-app
-```
-
-Next, we recommend using a [Python virtual environment](https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/#creating-a-virtual-environment) to manage your project's dependencies. This is a great way to prevent conflicts with your system's Python packages. Let's create and activate a new virtual environment with [Python 3.6 or later](https://www.python.org/downloads/):
-
-```shell
-python3 -m venv .venv
-source .venv/bin/activate
-```
-
-We can confirm that the virtual environment is active by checking that the path to `python3` is _inside_ your project ([a similar command is available on Windows](https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/#activating-a-virtual-environment)):
-
-```shell
-which python3
-# Output: /path/to/first-bolt-app/.venv/bin/python3
-```
-
-Before we install the Bolt for Python package to your new project, let's save the **bot token** and **app-level token** that were generated when you configured your app. 
-
-1. **Copy your bot (xoxb) token from the OAuth & Permissions page** and store it in a new environment variable. The following example works on Linux and macOS; but [similar commands are available on Windows](https://superuser.com/questions/212150/how-to-set-env-variable-in-windows-cmd-line/212153#212153).
-```shell
-export SLACK_BOT_TOKEN=xoxb-<your-bot-token>
-```
-
-2. **Copy your app-level (xapp) token from the Basic Information page** and then store it in a new environment variable. 
-```shell
-export SLACK_APP_TOKEN=<your-app-level-token>
-```
-
-> 🔒 Remember to keep all tokens secure. At a minimum, you should avoid checking them into public version control, and access them via environment variables as we've done above. Checkout the API documentation for more on [best practices for app security](https://api.slack.com/authentication/best-practices).
-
-Now, let's create your app. Install the `slack_bolt` Python package to your virtual environment using the following command:
-
-```shell
-pip install slack_bolt
-```
-
-Create a new file called `app.py` in this directory and add the following code:
-
-```python
-import os
-from slack_bolt import App
-from slack_bolt.adapter.socket_mode import SocketModeHandler
-
-# Initializes your app with your bot token and socket mode handler
-app = App(token=os.environ.get("SLACK_BOT_TOKEN"))
-
-# Start your app
-if __name__ == "__main__":
-    SocketModeHandler(app, os.environ["SLACK_APP_TOKEN"]).start()
-```
-
-Your tokens are enough to create your first Bolt app. Save your `app.py` file then on the command line run the following:
-
-```script
-python3 app.py
-```
-
-Your app should let you know that it's up and running. 🎉
-
----
-
-### Setting up events {#setting-up-events}
-Your app behaves similarly to people on your team — it can post messages, add emoji reactions, and listen and respond to events. 
-
-To listen for events happening in a Slack workspace (like when a message is posted or when a reaction is posted to a message) you'll use the [Events API to subscribe to event types](https://api.slack.com/events-api).
-
-> 💡 Earlier in this tutorial we enabled Socket Mode. Socket Mode lets apps use the Events API and interactive components without exposing a public HTTP endpoint. This can be helpful during development, or if you're receiving requests from behind a firewall. HTTP is more useful for apps being deployed to hosting environments, or apps intended for distribution via the Slack App Directory. To follow this getting started guide with HTTP instead, head over [here](/bolt-python/tutorial/getting-started-http).  
-
-It's time to tell Slack what events we'd like to listen for.
-
-When an event occurs, Slack will send your app some information about the event, like the user that triggered it and the channel it occurred in. Your app will process the details and can respond accordingly.
-
-Navigate to **Event Subscriptions** on the left sidebar and toggle to enable. Under **Subscribe to Bot Events**, you can add events for your bot to respond to. There are four events related to messages:
-- [`message.channels`](https://api.slack.com/events/message.channels) listens for messages in public channels that your app is added to
-- [`message.groups`](https://api.slack.com/events/message.groups) listens for messages in 🔒 private channels that your app is added to
-- [`message.im`](https://api.slack.com/events/message.im) listens for messages in your app's DMs with users
-- [`message.mpim`](https://api.slack.com/events/message.mpim) listens for messages in multi-person DMs that your app is added to
-
-If you want your bot to listen to messages from everywhere it is added to, choose all four message events. After you’ve selected the events you want your bot to listen to, click the green **Save Changes** button.
-
----
-
-### Listening and responding to a message {#listening-and-responding-to-a-message}
-Your app is now ready for some logic. Let's start by using the `message()` method to attach a listener for messages.
-
-The following example listens and responds to all messages in channels/DMs where your app has been added that contain the word "hello":
-
-```python
-import os
-from slack_bolt import App
-from slack_bolt.adapter.socket_mode import SocketModeHandler
-
-# Initializes your app with your bot token and socket mode handler
-app = App(token=os.environ.get("SLACK_BOT_TOKEN"))
-
-# Listens to incoming messages that contain "hello"
-# To learn available listener arguments,
-# visit https://slack.dev/bolt-python/api-docs/slack_bolt/kwargs_injection/args.html
-@app.message("hello")
-def message_hello(message, say):
-    # say() sends a message to the channel where the event was triggered
-    say(f"Hey there <@{message['user']}>!")
-
-# Start your app
-if __name__ == "__main__":
-    SocketModeHandler(app, os.environ["SLACK_APP_TOKEN"]).start()
-```
-
-If you restart your app, so long as your bot user has been added to the channel/DM, when you send any message that contains "hello", it will respond.
-
-This is a basic example, but it gives you a place to start customizing your app based on your own goals. Let's try something a little more interactive by sending a button rather than plain text.
-
----
-
-### Sending and responding to actions {#sending-and-responding-to-actions}
-
-To use features like buttons, select menus, datepickers, modals, and shortcuts, you’ll need to enable interactivity. Head over to **Interactivity & Shortcuts** in your app configuration.
-
-> 💡 You’ll notice that with Socket Mode on, basic interactivity is enabled for us by default, so no further action here is needed. If you’re using HTTP, you’ll need to supply a Request URL for Slack to send events to.
-
-When interactivity is enabled, interactions with shortcuts, modals, or interactive components (such as buttons, select menus, and datepickers) will be sent to your app as events.
-
-Now, let's go back to your app's code and add logic to handle those events:
-- First, we'll send a message that contains an interactive component (in this case a button)
-- Next, we'll listen for the action of a user clicking the button before responding
-
-Below, the code from the last section is modified to send a message containing a button rather than just a string:
-
-```python
-import os
-from slack_bolt import App
-from slack_bolt.adapter.socket_mode import SocketModeHandler
-
-# Initializes your app with your bot token and socket mode handler
-app = App(
-    token=os.environ.get("SLACK_BOT_TOKEN"),
-    # signing_secret=os.environ.get("SLACK_SIGNING_SECRET") # not required for socket mode
-)
-
-# Listens to incoming messages that contain "hello"
-@app.message("hello")
-def message_hello(message, say):
-    # say() sends a message to the channel where the event was triggered
-    say(
-        blocks=[
-            {
-                "type": "section",
-                "text": {"type": "mrkdwn", "text": f"Hey there <@{message['user']}>!"},
-                "accessory": {
-                    "type": "button",
-                    "text": {"type": "plain_text", "text": "Click Me"},
-                    "action_id": "button_click"
-                }
-            }
-        ],
-        text=f"Hey there <@{message['user']}>!"
-    )
-
-# Start your app
-if __name__ == "__main__":
-    SocketModeHandler(app, os.environ["SLACK_APP_TOKEN"]).start()
-
-```
-
-The value inside of `say()` is now an object that contains an array of `blocks`. Blocks are the building components of a Slack message and can range from text to images to datepickers. In this case, your app will respond with a section block that includes a button as an accessory. Since we're using `blocks`, the `text` is a fallback for notifications and accessibility.
-
-You'll notice in the button `accessory` object, there is an `action_id`. This will act as a unique identifier for the button so your app can specify what action it wants to respond to.
-
-> 💡 The [Block Kit Builder](https://app.slack.com/block-kit-builder) is an simple way to prototype your interactive messages. The builder lets you (or anyone on your team) mockup messages and generates the corresponding JSON that you can paste directly in your app.
-
-Now, if you restart your app and say "hello" in a channel your app is in, you'll see a message with a button. But if you click the button, nothing happens (*yet!*).
-
-Let's add a handler to send a followup message when someone clicks the button:
-
-```python
-import os
-from slack_bolt import App
-from slack_bolt.adapter.socket_mode import SocketModeHandler
-
-# Initializes your app with your bot token and socket mode handler
-app = App(token=os.environ.get("SLACK_BOT_TOKEN"))
-
-# Listens to incoming messages that contain "hello"
-@app.message("hello")
-def message_hello(message, say):
-    # say() sends a message to the channel where the event was triggered
-    say(
-        blocks=[
-            {
-                "type": "section",
-                "text": {"type": "mrkdwn", "text": f"Hey there <@{message['user']}>!"},
-                "accessory": {
-                    "type": "button",
-                    "text": {"type": "plain_text", "text": "Click Me"},
-                    "action_id": "button_click"
-                }
-            }
-        ],
-        text=f"Hey there <@{message['user']}>!"
-    )
-
-@app.action("button_click")
-def action_button_click(body, ack, say):
-    # Acknowledge the action
-    ack()
-    say(f"<@{body['user']['id']}> clicked the button")
-
-# Start your app
-if __name__ == "__main__":
-    SocketModeHandler(app, os.environ["SLACK_APP_TOKEN"]).start()
-```
-
-You can see that we used `app.action()` to listen for the `action_id` that we named `button_click`. If you restart your app and click the button, you'll see a new message from your app that says you clicked the button.

-### Next steps {#next-steps}
-You just built your first [Bolt for Python app](https://github.com/slackapi/bolt-python/tree/main/examples/getting_started) with Socket Mode! 🎉
-
-Now that you have a basic app up and running, you can start exploring how to make your Bolt app stand out. Here are some ideas about what to explore next:
-
-* Read through the [Basic concepts](/bolt-python/concepts#basic) to learn about the different methods and features your Bolt app has access to.
-
-* Explore the different events your bot can listen to with the [`events()` method](/bolt-python/concepts#event-listening). All of the events are listed [on the API site](https://api.slack.com/events).
-
-* Bolt allows you to [call Web API methods](/bolt-python/concepts#web-api) with the client attached to your app. There are [over 220 methods](https://api.slack.com/methods) on our API site.
-
-* Learn more about the different token types [on our API site](https://api.slack.com/docs/token-types). Your app may need different tokens depending on the actions you want it to perform. For apps that do not use Socket Mode, typically only the bot (`xoxb`) token and Signing Secret are required. For example of this, see our parallel guide [Getting Started with HTTP](/bolt-python/tutorial/getting-started-http).

-# Getting started with Bolt for Python over HTTP
-
-<div class="section-content">
-This guide is meant to walk you through getting up and running with a Slack app using **Bolt for Python over HTTP**. Along the way, we’ll create a new Slack app, set up your local environment, and develop an app that listens and responds to messages from a Slack workspace.
-</div>
-
-When you're finished, you'll have this ⚡️[Getting Started with Slack app](https://github.com/slackapi/bolt-python/tree/main/examples/getting_started) to run, modify, and make your own.
-
----
-
-### Create an app {#create-an-app}
-First thing's first: before you start developing with Bolt, you'll want to [create a Slack app](https://api.slack.com/apps/new).
-
-> 💡 We recommend using a workspace where you won't disrupt real work getting done — [you can create a new one for free](https://slack.com/get-started#create).
-
-After you fill out an app name (_you can change it later_) and pick a workspace to install it to, hit the `Create App` button and you'll land on your app's **Basic Information** page.
-
-This page contains an overview of your app in addition to important credentials you'll need later, like the `Signing Secret` under the **App Credentials** header.
-
-![Basic Information page](../assets/basic-information-page.png "Basic Information page")
-
-Look around, add an app icon and description, and then let's start configuring your app 🔩
-
----
-
-### Tokens and installing apps {#tokens-and-installing-apps}
-Slack apps use [OAuth to manage access to Slack's APIs](https://api.slack.com/docs/oauth). When an app is installed, you'll receive a token that the app can use to call API methods.
-
-There are three main token types available to a Slack app: user (`xoxp`), bot (`xoxb`), and app-level (`xapp`) tokens. 
-- [User tokens](https://api.slack.com/authentication/token-types#user) allow you to call API methods on behalf of users after they install or authenticate the app. There may be several user tokens for a single workspace. 
-- [Bot tokens](https://api.slack.com/authentication/token-types#bot) are associated with bot users, and are only granted once in a workspace where someone installs the app. The bot token your app uses will be the same no matter which user performed the installation. Bot tokens are the token type that _most_ apps use.
-- [App-level tokens](https://api.slack.com/authentication/token-types#app) represent your app across organizations, including installations by all individual users on all workspaces in a given organization and are commonly used for creating websocket connections to your app.
-
-For brevity, we're going to use bot tokens for this guide.
-
-1. Navigate to the **OAuth & Permissions** on the left sidebar and scroll down to the **Bot Token Scopes** section. Click **Add an OAuth Scope**.
-
-2. For now, we'll just add one scope: [`chat:write`](https://api.slack.com/scopes/chat:write). This grants your app the permission to post messages in channels it's a member of.
-
-3. Scroll up to the top of the OAuth & Permissions page and click **Install App to Workspace**. You'll be led through Slack's OAuth UI, where you should allow your app to be installed to your development workspace.
-
-4. Once you authorize the installation, you'll land on the **OAuth & Permissions** page and see a **Bot User OAuth Access Token**. We'll use that in just a moment.
-
-![OAuth Tokens](../assets/bot-token.png "Bot OAuth Token")
-
-> 💡 Treat your token like a password and [keep it safe](https://api.slack.com/docs/oauth-safety). Your app uses it to post and retrieve information from Slack workspaces.
-
----
-
-### Setting up your project {#setting-up-your-project}
-With the initial configuration handled, it's time to set up a new Bolt project. This is where you'll write the code that handles the logic for your app.
-
-If you don’t already have a project, let’s create a new one. Create an empty directory:
-
-```shell
-mkdir first-bolt-app
-cd first-bolt-app
-```
-
-Next, we recommend using a [Python virtual environment](https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/#creating-a-virtual-environment) to manage your project's dependencies. This is a great way to prevent conflicts with your system's Python packages. Let's create and activate a new virtual environment with [Python 3.6 or later](https://www.python.org/downloads/):
-
-```shell
-python3 -m venv .venv
-source .venv/bin/activate
-```
-
-We can confirm that the virtual environment is active by checking that the path to `python3` is _inside_ your project ([a similar command is available on Windows](https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/#activating-a-virtual-environment)):
-
-```shell
-which python3
-# Output: /path/to/first-bolt-app/.venv/bin/python3
-```
-
-Before we install the Bolt for Python package to your new project, let's save the **bot token** and **signing secret** that were generated when you configured your app. 
-
-1. **Copy your Signing Secret from the Basic Information page** and then store it in a new environment variable. The following example works on Linux and macOS; but [similar commands are available on Windows](https://superuser.com/questions/212150/how-to-set-env-variable-in-windows-cmd-line/212153#212153).
-```shell
-export SLACK_SIGNING_SECRET=<your-signing-secret>
-```
-
-2. **Copy your bot (xoxb) token from the OAuth & Permissions page** and store it in another environment variable.
-```shell
-export SLACK_BOT_TOKEN=xoxb-<your-bot-token>
-```
-> 🔒 Remember to keep your tokens and signing secret secure. At a minimum, you should avoid checking them into public version control, and access them via environment variables as we've done above. Checkout the API documentation for more on [best practices for app security](https://api.slack.com/authentication/best-practices).
-
-Now, let's create your app. Install the `slack_bolt` Python package to your virtual environment using the following command:
-
-```shell
-pip install slack_bolt
-```
-
-Create a new file called `app.py` in this directory and add the following code:
-
-```python
-import os
-from slack_bolt import App
-
-# Initializes your app with your bot token and signing secret
-app = App(
-    token=os.environ.get("SLACK_BOT_TOKEN"),
-    signing_secret=os.environ.get("SLACK_SIGNING_SECRET")
-)
-
-# Start your app
-if __name__ == "__main__":
-    app.start(port=int(os.environ.get("PORT", 3000)))
-```
-
-Your token and signing secret are enough to create your first Bolt app. Save your `app.py` file then on the command line run the following:
-
-```script
-python3 app.py
-```
-
-Your app should let you know that it's up and running. 🎉
-
----
-
-### Setting up events over HTTP {#setting-up-events}
-Your app behaves similarly to people on your team — it can post messages, add emoji reactions, and listen and respond to events. 
-
-To listen for events happening in a Slack workspace (like when a message is posted or when a reaction is posted to a message) you'll use the [Events API to subscribe to event types](https://api.slack.com/events-api).
-
-Let's enable events for your app: 
-1. Go back to your app configuration page (click on the app [from your app management page](https://api.slack.com/apps)). Click **Event Subscriptions** on the left sidebar. Toggle the switch labeled **Enable Events**.
-
-2. Add your Request URL. Slack will send HTTP POST requests corresponding to events to this [Request URL](https://api.slack.com/apis/connections/events-api#the-events-api__subscribing-to-event-types__events-api-request-urls) endpoint. Bolt uses the `/slack/events` path to listen to all incoming requests (whether shortcuts, events, or interactivity payloads). When configuring your Request URL within your app configuration, you'll append `/slack/events`, e.g. `https://<your-domain>/slack/events`. 💡 As long as your Bolt app is still running, your URL should become verified.
-
-> 💡 For local development, you can use a proxy service like ngrok to create a public URL and tunnel requests to your development environment. Refer to [ngrok's getting started guide](https://ngrok.com/docs#getting-started-expose) on how to create this tunnel. And when you get to hosting your app, we've collected some of the most common hosting providers Slack developers use to host their apps [on our API site](https://api.slack.com/docs/hosting). 
-
-Finally, it's time to tell Slack what events we'd like to listen for.
-
-When an event occurs, Slack will send your app some information about the event, like the user that triggered it and the channel it occurred in. Your app will process the details and can respond accordingly.
-
-Navigate to **Event Subscriptions** on the left sidebar and toggle to enable. Under **Subscribe to Bot Events**, you can add events for your bot to respond to. There are four events related to messages:
-- [`message.channels`](https://api.slack.com/events/message.channels) listens for messages in public channels that your app is added to
-- [`message.groups`](https://api.slack.com/events/message.groups) listens for messages in 🔒 private channels that your app is added to
-- [`message.im`](https://api.slack.com/events/message.im) listens for messages in your app's DMs with users
-- [`message.mpim`](https://api.slack.com/events/message.mpim) listens for messages in multi-person DMs that your app is added to
-
-If you want your bot to listen to messages from everywhere it is added to, choose all four message events. After you’ve selected the events you want your bot to listen to, click the green **Save Changes** button.
-
----
-
-### Listening and responding to a message {#listening-and-responding-to-a-message}
-Your app is now ready for some logic. Let's start by using the `message()` method to attach a listener for messages.
-
-The following example listens and responds to all messages in channels/DMs where your app has been added that contain the word "hello":
-
-```python
-import os
-from slack_bolt import App
-
-# Initializes your app with your bot token and signing secret
-app = App(
-    token=os.environ.get("SLACK_BOT_TOKEN"),
-    signing_secret=os.environ.get("SLACK_SIGNING_SECRET")
-)
-
-# Listens to incoming messages that contain "hello"
-# To learn available listener arguments,
-# visit https://slack.dev/bolt-python/api-docs/slack_bolt/kwargs_injection/args.html
-@app.message("hello")
-def message_hello(message, say):
-    # say() sends a message to the channel where the event was triggered
-    say(f"Hey there <@{message['user']}>!")
-
-# Start your app
-if __name__ == "__main__":
-    app.start(port=int(os.environ.get("PORT", 3000)))
-```
-
-If you restart your app, so long as your bot user has been added to the channel/DM, when you send any message that contains "hello", it will respond.
-
-This is a basic example, but it gives you a place to start customizing your app based on your own goals. Let's try something a little more interactive by sending a button rather than plain text.
-
----
-
-### Sending and responding to actions {#sending-and-responding-to-actions}
-
-To use features like buttons, select menus, datepickers, modals, and shortcuts, you’ll need to enable interactivity. Similar to events, you'll need to specify a URL for Slack to send the action (such as *user clicked a button*).
-
-Back on your app configuration page, click on **Interactivity & Shortcuts** on the left side. You'll see that there's another **Request URL** box.
-
-> 💡 By default, Bolt is configured to use the same endpoint for interactive components that it uses for events, so use the same request URL as above (for example, `https://8e8ec2d7.ngrok.io/slack/events`). Press the **Save Changes** button in the lower right hand corner, and that's it. Your app is set up to handle interactivity!
-
-![Configuring a Request URL](../assets/request-url-config.png "Configuring a Request URL")
-
-When interactivity is enabled, interactions with shortcuts, modals, or interactive components (such as buttons, select menus, and datepickers) will be sent to your app as events.
-
-Now, let's go back to your app's code and add logic to handle those events:
-- First, we'll send a message that contains an interactive component (in this case a button)
-- Next, we'll listen for the action of a user clicking the button before responding
-
-Below, the code from the last section is modified to send a message containing a button rather than just a string:
-
-```python
-import os
-from slack_bolt import App
-
-# Initializes your app with your bot token and signing secret
-app = App(
-    token=os.environ.get("SLACK_BOT_TOKEN"),
-    signing_secret=os.environ.get("SLACK_SIGNING_SECRET")
-)
-
-# Listens to incoming messages that contain "hello"
-@app.message("hello")
-def message_hello(message, say):
-    # say() sends a message to the channel where the event was triggered
-    say(
-        blocks=[
-            {
-                "type": "section",
-                "text": {"type": "mrkdwn", "text": f"Hey there <@{message['user']}>!"},
-                "accessory": {
-                    "type": "button",
-                    "text": {"type": "plain_text", "text": "Click Me"},
-                    "action_id": "button_click"
-                }
-            }
-        ],
-        text=f"Hey there <@{message['user']}>!"
-    )
-
-# Start your app
-if __name__ == "__main__":
-    app.start(port=int(os.environ.get("PORT", 3000)))
-```
-
-The value inside of `say()` is now an object that contains an array of `blocks`. Blocks are the building components of a Slack message and can range from text to images to datepickers. In this case, your app will respond with a section block that includes a button as an accessory. Since we're using `blocks`, the `text` is a fallback for notifications and accessibility.
-
-You'll notice in the button `accessory` object, there is an `action_id`. This will act as a unique identifier for the button so your app can specify what action it wants to respond to.
-
-> 💡 The [Block Kit Builder](https://app.slack.com/block-kit-builder) is an simple way to prototype your interactive messages. The builder lets you (or anyone on your team) mockup messages and generates the corresponding JSON that you can paste directly in your app.
-
-Now, if you restart your app and say "hello" in a channel your app is in, you'll see a message with a button. But if you click the button, nothing happens (*yet!*).
-
-Let's add a handler to send a followup message when someone clicks the button:
-
-```python
-import os

-
-# Initializes your app with your bot token and signing secret
-app = App(
-    token=os.environ.get("SLACK_BOT_TOKEN"),
-    signing_secret=os.environ.get("SLACK_SIGNING_SECRET")
-)
-
-# Listens to incoming messages that contain "hello"
-@app.message("hello")
-def message_hello(message, say):
-    # say() sends a message to the channel where the event was triggered
-    say(
-        blocks=[
-            {
-                "type": "section",
-                "text": {"type": "mrkdwn", "text": f"Hey there <@{message['user']}>!"},
-                "accessory": {
-                    "type": "button",
-                    "text": {"type": "plain_text", "text": "Click Me"},
-                    "action_id": "button_click"
-                }
-            }
-        ],
-        text=f"Hey there <@{message['user']}>!"
-    )
-
-@app.action("button_click")
-def action_button_click(body, ack, say):
-    # Acknowledge the action
-    ack()
-    say(f"<@{body['user']['id']}> clicked the button")
-
-# Start your app
-if __name__ == "__main__":
-    app.start(port=int(os.environ.get("PORT", 3000)))
-```
-
-You can see that we used `app.action()` to listen for the `action_id` that we named `button_click`. If you restart your app and click the button, you'll see a new message from your app that says you clicked the button.

-### Next steps {#next-steps}
-You just built your first [Bolt for Python app](https://github.com/slackapi/bolt-python/tree/main/examples/getting_started)! 🎉

-# Bolt 入門ガイド
-
-<div class="section-content">
-このガイドでは、Bolt for Python を使った Slack アプリの設定と起動する方法について説明します。ここで説明する手順は、新しい Slack アプリを作成し、ローカルの開発環境をセットアップし、Slack ワークスペースからのメッセージをリッスンして応答するアプリを開発するという流れになります。
-</div>
-
-この手順を全て終わらせたら、あなたはきっと ⚡️[Slack アプリのはじめ方](https://github.com/slackapi/bolt-python/tree/main/examples/getting_started)のサンプルアプリを動作させたり、それに変更を加えたり、自分のアプリを作ったりすることができるようになるでしょう。
-
-> 💡 このガイドでは[ソケットモード](https://api.slack.com/apis/connections/socket) を利用します。ソケットモードは、Slack アプリ開発をとりあえず始めてみるときやあなたのチームだけのためのアプリをつくるときにおすすめのやり方です。もしすでに HTTP をアプリのコミュニケーションプロトコルとしてするとわかっているなら、HTTP の方式に対応した同様のドキュメントである [Bolt 入門ガイド（HTTP）](/bolt-python/ja-jp/tutorial/getting-started-http) を参照してください。
-
----
-
-### アプリを作成する {#create-an-app}
-最初にやるべきこと : Bolt での開発を始める前に、[Slack アプリを作成](https://api.slack.com/apps/new)します。
-
-> 💡 いつもの仕事のさまたげにならないように、別の開発用のワークスペースを使用することをおすすめします。[新しいワークスペースは無料で作成できます](https://slack.com/get-started#create)。
-
-アプリ名を入力し（_後で変更可能_）、インストール先のワークスペースを選択したら、「`Create App`」ボタンをクリックすると、アプリの **Basic Information** ページが表示されます。
-
-このページでは、アプリの概要や、重要な認証情報も確認できます。この情報は後ほど参照します。
-
-![Basic Information ページ](../../assets/basic-information-page.png "Basic Information ページ")
-
-ひと通り確認し、アプリのアイコンと説明を追加したら、アプリの構成 🔩 を始めましょう。
-
----
-
-### トークンとアプリのインストール {#tokens-and-installing-apps}
-Slack アプリでは、[Slack API へのアクセスの管理に OAuth を使用します](https://api.slack.com/docs/oauth)。アプリがインストールされると、トークンが発行されます。アプリはそのトークンを使って API メソッドを呼び出すことができます。
-
-Slack アプリで使用できるトークンには、ユーザートークン（`xoxp`）とボットトークン（`xoxb`）、アプリレベルトークン（`xapp`）の 3 種類があります。
-- [ユーザートークン](https://api.slack.com/authentication/token-types#user) を使用すると、アプリをインストールまたは認証したユーザーに成り代わって API メソッドを呼び出すことができます。1 つのワークスペースに複数のユーザートークンが存在する可能性があります。
-- [ボットトークン](https://api.slack.com/authentication/token-types#bot) はボットユーザーに関連づけられ、1 つのワークスペースでは最初に誰かがそのアプリをインストールした際に一度だけ発行されます。どのユーザーがインストールを実行しても、アプリが使用するボットトークンは同じになります。_ほとんど_のアプリで使用されるのは、ボットトークンです。
-- [アプリレベルトークン](https://api.slack.com/authentication/token-types#app) は、全ての組織（とその配下のワークスペースでの個々のユーザーによるインストール）を横断して、あなたのアプリを代理するものです。アプリレベルトークンは、アプリの WebSocket コネクションを確立するためによく使われます。
-
-このガイドではボットトークンとアプリレベルトークンを使用します。
-
-1. 左サイドバーの「**OAuth & Permissions**」をクリックし、「**Bot Token Scopes**」セクションまで下にスクロールします。「**Add an OAuth Scope**」をクリックします。
-
-2. ここでは [`chat:write`](https://api.slack.com/scopes/chat:write) というスコープのみを追加します。このスコープは、アプリが参加しているチャンネルにメッセージを投稿することを許可します。
-
-3. OAuth & Permissions ページの一番上までスクロールし、「**Install App to Workspace**」をクリックします。Slack の OAuth 確認画面 が表示されます。この画面で開発用ワークスペースへのアプリのインストールを承認します。
-
-4. インストールを承認すると **OAuth & Permissions** ページが表示され、**Bot User OAuth Access Token** を確認できるでしょう。
-
-![OAuth トークン](../../assets/bot-token.png "ボット用 OAuth トークン")
-
-5. 次に「**Basic Informationのページ**」まで戻り、アプリトークンのセクションまで下にスクロールし「**Generate Token and Scopes**」をクリックしてアプリレベルトークンを作成します。このトークンに `connections:write` のスコープを付与し、作成された `xapp` トークンを保存します。これらのトークンは後ほど利用します。
-
-6. 左サイドメニューの「**Socket Mode**」を有効にします。
-
-> 💡 トークンはパスワードと同様に取り扱い、[安全な方法で保管してください](https://api.slack.com/docs/oauth-safety)。アプリはこのトークンを使って Slack ワークスペースで投稿をしたり、情報の取得をしたりします。

-
-### プロジェクトをセットアップする {#setting-up-your-project}
-初期設定が終わったら、新しい Bolt プロジェクトのセットアップを行いましょう。このプロジェクトが、あなたのアプリのロジックを処理するコードを配置する場所となります。
-
-プロジェクトをまだ作成していない場合は、新しく作成しましょう。空のディレクトリを作成します。
-
-```shell
-mkdir first-bolt-app
-cd first-bolt-app
-```
-
-次に、プロジェクトの依存関係を管理する方法として、[Python 仮想環境](https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/#creating-a-virtual-environment)を使ったおすすめの方法を紹介します。これはシステム Python に存在するパッケージとのコンフリクトを防ぐために推奨されている優れた方法です。[Python 3.6 以降](https://www.python.org/downloads/)の仮想環境を作成し、アクティブにしてみましょう。
-
-```shell
-python3 -m venv .venv
-source .venv/bin/activate
-```
-
-`python3` へのパスがプロジェクトの中を指していることを確かめることで、仮想環境がアクティブになっていることを確認できます（[Windows でもこれに似たコマンドが利用できます](https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/#activating-a-virtual-environment)）。
-
-```shell
-which python3
-# 出力結果 : /path/to/first-bolt-app/.venv/bin/python3
-```
-
-Bolt for Python のパッケージを新しいプロジェクトにインストールする前に、アプリの設定時に作成された **ボットトークン** と **アプリレベルトークン** を保存しましょう。
-
-1. **OAuth & Permissions ページのボットトークン (xoxb) をコピー**して、新しい環境変数に保存します。以下のコマンド例は Linux と macOS で利用できます。[Windows でもこれに似たコマンドが利用できます](https://superuser.com/questions/212150/how-to-set-env-variable-in-windows-cmd-line/212153#212153)。
-```shell
-export SLACK_BOT_TOKEN=xoxb-<ボットトークン>
-```
-
-2. **Basic Information ページのアプリレベルトークン（xapp）をコピー**して、別の環境変数に保存します。
-```shell
-export SLACK_APP_TOKEN=<アプリレベルトークン>
-```
-
-> 🔒 全てのトークンは安全に保管してください。少なくともパブリックなバージョン管理にチェックインするようなことは避けるべきでしょう。また、上にあった例のように環境変数を介してアクセスするようにしてください。詳細な情報は [アプリのセキュリティのベストプラクティス](https://api.slack.com/authentication/best-practices)のドキュメントを参照してください。
-
-
-完了したら、アプリを作ってみましょう。以下のコマンドを使って、仮想環境に Python の `slack_bolt` パッケージをインストールします。
-
-```shell
-pip install slack_bolt
-```
-
-このディレクトリに「`app.py`」という名前の新しいファイルを作成し、以下のコードを追加します。
-
-```python
-import os
-from slack_bolt import App
-from slack_bolt.adapter.socket_mode import SocketModeHandler
-
-# ボットトークンとソケットモードハンドラーを使ってアプリを初期化します
-app = App(token=os.environ.get("SLACK_BOT_TOKEN"))
-
-# アプリを起動します
-if __name__ == "__main__":
-    SocketModeHandler(app, os.environ["SLACK_APP_TOKEN"]).start()
-```
-
-このようにトークンさえあれば、最初の Bolt アプリを作成することができます。「`app.py`」ファイルを保存して、コマンドラインで以下を実行します。
-
-```script
-python3 app.py
-```
-
-アプリが起動し、実行中であることが表示されます。🎉

-
-### イベントを設定する {#setting-up-events}
-アプリはワークスペース内の他のメンバーと同じように振る舞い、メッセージを投稿したり、絵文字リアクションを追加したり、イベントをリッスンして返答したりできます。
-
-Slack ワークスペースで発生するイベント（メッセージが投稿されたときや、メッセージに対するリアクションがつけられたときなど）をリッスンするには、[Events API を使って特定の種類のイベントをサブスクライブします](https://api.slack.com/events-api)。
-
-> 💡 このチュートリアルの序盤でソケットモードを有効にしました。ソケットモードを使うことで、アプリが公開された HTTP エンドポイントを公開せずに Events API やインタラクティブコンポーネントを利用できるようになります。このことは、開発時やファイヤーウォールの裏からのリクエストを受ける際に便利です。HTTP での方式はホスティング環境にデプロイするアプリや Slack App Directoryで配布されるアプリに適しています。HTTP での情報については[このドキュメント](/bolt-python/ja-jp/tutorial/getting-started-http)を参照してください。
-
-それでは、私たちがどのイベントをリッスンしたいかを Slack に伝えましょう。
-
-イベントが発生すると、そのイベントをトリガーしたユーザーやイベントが発生したチャンネルなど、イベントに関する情報が Slack からアプリに送信されます。アプリではこれらの情報を処理して、適切な応答を返します。
-
-左側のサイドバーから **Event Subscriptions** にアクセスして、機能を有効にしてください。 **Subscribe to Bot Events** 配下で、ボットが受け取れる　イベントを追加することができます。4つのメッセージに関するイベントがあります。
-- [`message.channels`](https://api.slack.com/events/message.channels) アプリが参加しているパブリックチャンネルのメッセージをリッスン
-- [`message.groups`](https://api.slack.com/events/message.groups) アプリが参加しているプライベートチャンネルのメッセージをリッスン
-- [`message.im`](https://api.slack.com/events/message.im) あなたのアプリとユーザーのダイレクトメッセージをリッスン
-- [`message.mpim`](https://api.slack.com/events/message.mpim) あなたのアプリが追加されているグループ DM をリッスン
-
-ボットが参加するすべての場所のメッセージをリッスンさせるには、これら 4 つのメッセージイベントをすべて選択します。ボットにリッスンさせるメッセージイベントの種類を選択したら、「**Save Changes**」ボタンをクリックします。
-
----
-
-### メッセージをリッスンして応答する {#listening-and-responding-to-a-message}
-アプリにロジックを組み込む準備が整いました。まずは `message()` メソッドを使用して、メッセージのリスナーをアタッチしましょう。
-
-次の例では、アプリが参加するチャンネルとダイレクトメッセージに投稿されるすべてのメッセージをリッスンし、「hello」というメッセージに応答を返します。
-
-```python
-import os
-from slack_bolt import App
-from slack_bolt.adapter.socket_mode import SocketModeHandler
-
-# ボットトークンとソケットモードハンドラーを使ってアプリを初期化します
-app = App(token=os.environ.get("SLACK_BOT_TOKEN"))
-
-# 'hello' を含むメッセージをリッスンします
-# 指定可能なリスナーのメソッド引数の一覧は以下のモジュールドキュメントを参考にしてください：
-# https://slack.dev/bolt-python/api-docs/slack_bolt/kwargs_injection/args.html
-@app.message("hello")
-def message_hello(message, say):
-    # イベントがトリガーされたチャンネルへ say() でメッセージを送信します
-    say(f"Hey there <@{message['user']}>!")
-
-# アプリを起動します
-if __name__ == "__main__":
-    SocketModeHandler(app, os.environ["SLACK_APP_TOKEN"]).start()
-```
-
-アプリを再起動し、ボットユーザーが参加しているチャンネルまたはダイレクトメッセージに「hello」というメッセージを投稿すれば、アプリが応答するでしょう。
-
-これはごく基本的なコード例ですが、最終的にやりたいことを実現するためにアプリをカスタマイズするための起点として利用できます。プレーンテキストを送信する代わりにボタンを表示するという、もう少しインタラクティブな動作を試してみましょう。
-
----
-
-### アクションを送信して応答する {#sending-and-responding-to-actions}
-
-インタラクティブ機能を有効にすると、ボタン、選択メニュー、日付ピッカー、モーダル、ショートカットなどの機能が利用できるようになります。アプリ設定ページの「**Interactivity & Shortcuts**」にアクセスしてください。
-
-> 💡 ソケットモードを有効にしているとき、デフォルトで基本的なインタラクティブ機能が有効になっていることに気づくでしょう。追加のアクションは不要です。もし HTTP を使っている場合、Slack からのイベント送信先である Request URL を設定する必要があります。
-
-インタラクティビティが有効化されていれば、ショートカット、モーダル、インタラクティブコンポーネント (例：ボタン、選択メニュー、日付ピッカー) とのインタラクションはイベントとしてあなたのアプリに送信されます。
-
-それでは、アプリのコードに戻り、これらのイベントを処理する為のロジックを追加しましょう。
-- まず、インタラクティブコンポーネント（ここではボタン）を含んだメッセージをアプリから送信します。
-- 次に、ユーザーから返されるボタンクリックのアクションをリッスンし、それに応答します。
-
-以下のコードの後の部分を編集し、文字列だけのメッセージの代わりに、ボタンを含んだメッセージを送信するようにしてみます。
-
-```python
-import os
-from slack_bolt import App
-from slack_bolt.adapter.socket_mode import SocketModeHandler
-
-# ボットトークンとソケットモードハンドラーを使ってアプリを初期化します
-app = App(token=os.environ.get("SLACK_BOT_TOKEN"))
-
-# 'hello' を含むメッセージをリッスンします
-@app.message("hello")
-def message_hello(message, say):
-    # イベントがトリガーされたチャンネルへ say() でメッセージを送信します
-    say(
-        blocks=[
-            {
-                "type": "section",
-                "text": {"type": "mrkdwn", "text": f"Hey there <@{message['user']}>!"},
-                "accessory": {
-                    "type": "button",
-                    "text": {"type": "plain_text", "text":"Click Me"},
-                    "action_id": "button_click"
-                }
-            }
-        ],
-        text=f"Hey there <@{message['user']}>!"
-    )
-
-# アプリを起動します
-if __name__ == "__main__":
-    SocketModeHandler(app, os.environ["SLACK_APP_TOKEN"]).start()
-```
-
-`say()` の中の値を `blocks` という配列のオブジェクトに変えました。ブロックは Slack メッセージを構成するコンポーネントであり、テキストや画像、日付ピッカーなど、さまざまなタイプのブロックがあります。この例では `accessory` に `button` を持たせた「section」のブロックを、アプリからの応答に含めています。`blocks` を使用する場合、`text` は通知やアクセシビリティのためのフォールバックとなります。
-
-ボタンを含む `accessory` オブジェクトでは、`action_id` を指定していることがわかります。これは、ボタンを一意に示す識別子として機能します。これを使って、アプリをどのアクションに応答させるかを指定できます。
-
-> 💡 [Block Kit Builder](https://app.slack.com/block-kit-builder) を使用すると、インタラクティブなメッセージのプロトタイプを簡単に作成できます。自分自身やチームメンバーがメッセージのモックアップを作成し、生成される JSON をアプリに直接貼りつけることができます。
-
-アプリを再起動し、アプリが参加しているチャンネルで「hello」と入力すると、ボタン付きのメッセージが表示されるようになりました。ただし、ボタンをクリックしても、*まだ*何も起こりません。
-
-ハンドラーを追加して、ボタンがクリックされたときにフォローアップメッセージを送信するようにしてみましょう。
-
-```python
-import os
-from slack_bolt import App
-from slack_bolt.adapter.socket_mode import SocketModeHandler
-
-# ボットトークンと署名シークレットを使ってアプリを初期化します
-app = App(token=os.environ.get("SLACK_BOT_TOKEN"))
-
-# 'hello' を含むメッセージをリッスンします
-@app.message("hello")
-def message_hello(message, say):
-    # イベントがトリガーされたチャンネルへ say() でメッセージを送信します
-    say(
-        blocks=[
-            {
-                "type": "section",
-                "text": {"type": "mrkdwn", "text": f"Hey there <@{message['user']}>!"},
-                "accessory": {
-                    "type": "button",
-                    "text": {"type": "plain_text", "text":"Click Me"},
-                    "action_id": "button_click"
-                }
-            }
-        ],
-        text=f"Hey there <@{message['user']}>!"
-    )
-
-@app.action("button_click")
-def action_button_click(body, ack, say):
-    # アクションを確認したことを即時で応答します
-    ack()
-    # チャンネルにメッセージを投稿します
-    say(f"<@{body['user']['id']}> clicked the button")
-
-# アプリを起動します
-if __name__ == "__main__":
-    SocketModeHandler(app, os.environ["SLACK_APP_TOKEN"]).start()
-```
-
-`app.action()` を使って、先ほど命名した `button_click` という `action_id` をリッスンしています。アプリを再起動し、ボタンをクリックすると、アプリからの「clicked the button」というメッセージが新たに表示されるでしょう。
-

-
-### 次のステップ {#next-steps}
-はじめての [Bolt for Python アプリ](https://github.com/slackapi/bolt-python/tree/main/examples/getting_started)をソケットモードを使って構築することができました。🎉
-
-ここまでで基本的なアプリをセットアップして実行することはできたので、次は自分だけの Bolt アプリを作る方法を調べてみましょう。参考になりそうな記事をいくつかご紹介します。
-
-* [基本的な概念](/bolt-python/ja-jp/concepts#basic)について読んでみてください。Bolt アプリがアクセスできるさまざまメソッドや機能について知ることができます。
-* [`events()` メソッド](/bolt-python/ja-jp/concepts#event-listening)でボットがリッスンできるイベントをほかにも試してみましょう。すべてのイベントの一覧は [API サイト](https://api.slack.com/events)で確認できます。
-* Bolt では、アプリにアタッチされたクライアントから [Web API メソッドを呼び出す](/bolt-python/ja-jp/concepts#web-api)ことができます。API サイトに [220 以上のメソッド](https://api.slack.com/methods)を一覧しています。
-* [API サイト](https://api.slack.com/docs/token-types)でほかのタイプのトークンを確認してみてください。アプリで実行したいアクションによって、異なるトークンが必要になる場合があります。ソケットモードを使わないアプリでは、通常はボットトークン (`xoxb`) と署名シークレットが必要です。ソケットモードを使わない場合の例については、 HTTP 方式のやり方としてこのチュートリアルと対になっている [Bolt 入門ガイド（HTTP）](/bolt-python/ja-jp/tutorial/getting-started-http)を参照してください。

-# Bolt 入門ガイド（HTTP）
-
-<div class="section-content">
-このガイドでは、**HTTP上で Bolt for Python** を使った Slack アプリの設定と起動する方法について説明します。ここで説明する手順は、新しい Slack アプリを作成し、ローカルの開発環境をセットアップし、Slack ワークスペースからのメッセージをリッスンして応答するアプリを開発するという流れになります。
-</div>
-
-この手順を全て終わらせたら、あなたはきっと ⚡️[Slack アプリのはじめ方](https://github.com/slackapi/bolt-python/tree/main/examples/getting_started)のサンプルアプリを動作させたり、それに変更を加えたり、自分のアプリを作ったりすることができるようになるでしょう。
-
----
-
-### アプリを作成する {#create-an-app}
-最初にやるべきこと : Bolt での開発を始める前に、[Slack アプリを作成](https://api.slack.com/apps/new)します。
-
-> 💡 いつもの仕事のさまたげにならないように、別の開発用のワークスペースを使用することをおすすめします。[新しいワークスペースは無料で作成できます](https://slack.com/get-started#create)。
-
-アプリ名を入力し（_後で変更可能_）、インストール先のワークスペースを選択したら、「`Create App`」ボタンをクリックすると、アプリの **Basic Information** ページが表示されます。
-
-このページでは、アプリの概要を確認できます。また、「**App Credentials**」ヘッダーの下では「`Signing Secret`」などの重要な認証情報も確認できます。これらの認証情報は後で必要になります。
-
-
-![Basic Information ページ](../../assets/basic-information-page.png "Basic Information ページ")
-
-ひと通り確認し、アプリのアイコンと説明を追加したら、アプリの構成 🔩 を始めましょう。
-
----
-
-### トークンとアプリのインストール {#tokens-and-installing-apps}
-Slack アプリでは、[Slack API へのアクセスの管理に OAuth を使用します](https://api.slack.com/docs/oauth)。アプリがインストールされると、トークンが発行されます。アプリはそのトークンを使って API メソッドを呼び出すことができます。
-
-Slack アプリで使用できるトークンには、ユーザートークン（`xoxp`）とボットトークン（`xoxb`）、アプリレベルトークン（`xapp`）の 3 種類があります。
-- [ユーザートークン](https://api.slack.com/authentication/token-types#user) を使用すると、ユーザーがアプリをインストールまたは認証した後、アプリがそのユーザーを代理して API メソッドを呼び出すことができます。1 つのワークスペースに複数のユーザートークンが存在する可能性があります。
-- [ボットトークン](https://api.slack.com/authentication/token-types#bot) はボットユーザーに関連づけられ、1 つのワークスペースでは最初に誰かがそのアプリをインストールした際に一度だけ発行されます。どのユーザーがインストールを実行しても、アプリが使用するボットトークンは同じになります。_ほとんど_のアプリで使用されるのは、ボットトークンです。
-- [アプリレベルトークン](https://api.slack.com/authentication/token-types#app) は、組織に渡ってあなたのアプリを表すものです。所属する組織内の全てのワークスペースに、全ての個人ユーザによってインストールされたアプリについても同様です。アプリレベルトークンは WebSocket 通信を行うアプリを作る際に通常使われます。
-
-説明を簡潔にするために、このガイドではボットトークンを使用します。
-
-1. 左サイドバーの「**OAuth & Permissions**」をクリックし、「**Bot Token Scopes**」セクションまで下にスクロールします。「**Add an OAuth Scope**」をクリックします。
-
-2. ここでは [`chat:write`](https://api.slack.com/scopes/chat:write) というスコープのみを追加します。このスコープは、アプリが参加しているチャンネルにメッセージを投稿することを許可します。
-
-3. OAuth & Permissions ページの一番上までスクロールし、「**Install App to Workspace**」をクリックします。Slack の OAuth 確認画面 が表示されます。この画面で開発用ワークスペースへのアプリのインストールを承認します。
-
-4. インストールを承認すると **OAuth & Permissions** ページが表示され、**Bot User OAuth Access Token** を確認できるでしょう。このトークンはこのあと利用します。
-
-![OAuth トークン](../../assets/bot-token.png "ボット用 OAuth トークン")

-
-```shell
-which python3
-# 出力結果 : /path/to/first-bolt-app/.venv/bin/python3
-```
-
-Bolt for Python のパッケージを新しいプロジェクトにインストールする前に、アプリの設定時に作成された **ボットトークン** と **署名シークレット** を保存しましょう。
-
-1. **Basic Information ページの署名シークレットをコピー**して、新しい環境変数に保存します。以下のコマンド例は Linux と macOS で利用できます。[Windows でもこれに似たコマンドが利用できます](https://superuser.com/questions/212150/how-to-set-env-variable-in-windows-cmd-line/212153#212153)。
-```shell
-export SLACK_SIGNING_SECRET=<your-signing-secret>
-```
-
-2. **OAuth & Permissions ページのボットトークン (xoxb) をコピー**して、新しい環境変数に保存します。以下のコマンド例は Linux と macOS で利用できます。[Windows でもこれに似たコマンドが利用できます](https://superuser.com/questions/212150/how-to-set-env-variable-in-windows-cmd-line/212153#212153)。
-```shell
-export SLACK_BOT_TOKEN=xoxb-<your-bot-token>
-```
-
-> 🔒 全てのトークンは安全に保管してください。最低限、パブリックなバージョンコントロールにチェックインすることは避けてください。また、上記の例のように環境変数を介してアクセスするようにしてください。詳細な情報は [best practices for app security](https://api.slack.com/authentication/best-practices).のドキュメントを参照してください。
-
-
-完了したら、アプリを作ってみましょう。以下のコマンドを使って、仮想環境に Python の `slack_bolt` パッケージをインストールします。
-
-```shell
-pip install slack_bolt
-```
-
-このディレクトリに「`app.py`」という名前の新しいファイルを作成し、以下のコードを追加します。
-
-```python
-import os
-from slack_bolt import App
-from slack_bolt.adapter.socket_mode import SocketModeHandler

-)
-
-# アプリを起動します
-if __name__ == "__main__":
-    app.start(port=int(os.environ.get("PORT", 3000)))
-```
-
-このようにトークンがあれば、最初の Bolt アプリが作成できます。「`app.py`」ファイルを保存して、コマンドラインで以下を実行します。
-
-```script
-python3 app.py
-```
-
-アプリが起動し、実行中であることが表示されます。🎉
-
----
-
-### HTTP を利用したイベントを設定する {#setting-up-events}
-アプリはワークスペース内の他のメンバーと同じように振る舞い、メッセージを投稿したり、絵文字リアクションを追加したり、イベントをリッスンして返答したりできます。
-
-Slack ワークスペースで発生するイベント（メッセージが投稿されたときや、メッセージに対するリアクションがつけられたときなど）をリッスンするには、[Events API を使って特定の種類のイベントをサブスクライブします](https://api.slack.com/events-api)。
-
-それでは、アプリのイベント設定を有効化してみましょう。
-
-1. [アプリ管理ページ](https://api.slack.com/apps)でアプリをクリックします。次に、左サイドバーの「**Event Subscriptions**」をクリックします。「**Enable Events**」というラベルのスイッチをオンに切り替えます。
-2. リクエストURLを追加します。Slackはイベントに対応するHTTP POSTリクエストをこの [Request URL](https://api.slack.com/apis/connections/events-api#the-events-api__subscribing-to-event-types__events-api-request-urls) のエンドポイントに送信します。Bolt は `/slack/events` のエンドポイントで、全ての受信リクエストをリッスンします。これらのリクエストにはショートカット、イベント、インタラクションペイロードが含まれます。アプリの設定でエンドポイントを指定するときは、すべての Request URL の末尾に「/slack/events」を追加してください。例えば、 `https://<your-domain>/slack/events` のようになります。Bolt アプリが起動した状態のままなら、URL の検証が成功するはずです。
-
-> 💡 ローカル開発では、[ngrok](https://ngrok.com/)のようなプロキシサービスを使って公開 URL を作成し、リクエストを開発環境にトンネリングすることができます。このトンネリングの方法については、[ngrok のガイド](https://ngrok.com/docs#getting-started-expose)を参照してください。また、アプリのホスティングが必要になった場合には、[API サイトに](https://api.slack.com/docs/hosting) Slack開発者達がアプリのホスティングよく利用するホスティングプロバイダーを集めています。
-
-それでは、Slackにどのイベントをリッスンするかを教えてあげましょう。
-
-イベントが発生すると、そのイベントをトリガーしたユーザーやイベントが発生したチャンネルなど、イベントに関する情報が Slack からアプリに送信されます。アプリではこれらの情報を処理して、適切な応答を返します。
-
-左側のサイドバーから **Event Subscriptions** にアクセスして、機能を有効にしてください。 **Subscribe to Bot Events** 配下で、ボットが受け取れる　イベントを追加することができます。4つのメッセージに関するイベントがあります。

-- [`message.im`](https://api.slack.com/events/message.im) あなたのアプリとユーザーのダイレクトメッセージをリッスン
-- [`message.mpim`](https://api.slack.com/events/message.mpim) あなたのアプリが追加されているグループ DM をリッスン
-
-ボットが参加するすべての場所のメッセージをリッスンさせるには、これら 4 つのメッセージイベントをすべて選択します。ボットにリッスンさせるメッセージイベントの種類を選択したら、「**Save Changes**」ボタンをクリックします。

-### メッセージをリッスンして応答する {#listening-and-responding-to-a-message}
-アプリにロジックを組み込む準備が整いました。まずは `message()` メソッドを使用して、メッセージのリスナーをアタッチしましょう。
-
-次の例では、アプリが参加するチャンネルとダイレクトメッセージに投稿されるすべてのメッセージをリッスンし、「hello」というメッセージに応答を返します。
-
-```python
-import os
-from slack_bolt import App
-
-# ボットトークンと署名シークレットを使ってアプリを初期化します
-app = App(
-    token=os.environ.get("SLACK_BOT_TOKEN"),
-    signing_secret=os.environ.get("SLACK_SIGNING_SECRET")
-)
-
-# 'hello' を含むメッセージをリッスンします
-# 指定可能なリスナーのメソッド引数の一覧は以下のモジュールドキュメントを参考にしてください：
-# https://slack.dev/bolt-python/api-docs/slack_bolt/kwargs_injection/args.html
-@app.message("hello")
-def message_hello(message, say):
-    # イベントがトリガーされたチャンネルへ say() でメッセージを送信します
-    say(f"Hey there <@{message['user']}>!")
-
-# アプリを起動します
-if __name__ == "__main__":
-    app.start(port=int(os.environ.get("PORT", 3000)))
-```
-
-アプリを再起動し、ボットユーザーが参加しているチャンネルまたはダイレクトメッセージに「hello」というメッセージを投稿すれば、アプリが応答するでしょう。
-
-これはごく基本的なコード例ですが、最終的にやりたいことを実現するためにアプリをカスタマイズするための起点として利用できます。プレーンテキストを送信する代わりにボタンを表示するという、もう少しインタラクティブな動作を試してみましょう。
-
----
-
-### アクションを送信して応答する {#sending-and-responding-to-actions}
-
-インタラクティブ機能を有効にすると、ボタン、選択メニュー、日付ピッカー、モーダル、ショートカットなどの機能が利用できるようになります。イベントと同様に、Slack からのアクション（*ユーザーがボタンをクリックした*など）の送信先となる URL を設定する必要があります。
-
-アプリ設定ページに戻り、左サイドメニューの「**Interactivity & Shortcuts**」をクリックします。別の **Request URL** ボックスを見つけます。
-
-> 💡 デフォルトでは、Bolt はイベントに使用しているのと同じエンドポイントをインタラクティブコンポーネントにも使用するように設定されているため、上記と同じリクエスト URL（この例では「`https://8e8ec2d7.ngrok.io/slack/events`」）を使用します。このままの状態で、右下隅にある「**Save Changes**」ボタンを押してください。これでインタラクティブ機能がアプリで利用できるようになりました。
-
-![Request URL の設定](../../assets/request-url-config.png "Request URL の設定")
-
-インタラクティブ機能が有効化されている時、ショートカット、モーダル、インタラクティブコンポーネント (ボタンや、選択メニュー、日付ピッカー) とのインタラクションはイベントとしてアプリに対して送信されます。
-
-それでは、アプリのコードに戻り、これらのイベントを処理する為のロジックを追加しましょう。
-- まず、インタラクティブコンポーネントを含んだメッセージをアプリから送信します（このケースではボタン）。
-- 次に、ユーザーから返されるボタンクリックのアクションをリッスンし、それに応答します。
-
-以下のコードの後の部分を編集し、文字列だけのメッセージの代わりに、ボタンを含んだメッセージを送信するようにしてみます。
-
-```python
-import os
-from slack_bolt import App
-
-# ボットトークンと署名シークレットを使ってアプリを初期化します
-app = App(
-    token=os.environ.get("SLACK_BOT_TOKEN"),
-    signing_secret=os.environ.get("SLACK_SIGNING_SECRET")
-)
-
-# 'hello' を含むメッセージをリッスンします
-@app.message("hello")
-def message_hello(message, say):
-    # イベントがトリガーされたチャンネルへ say() でメッセージを送信します
-    say(
-        blocks=[
-            {
-                "type": "section",
-                "text": {"type": "mrkdwn", "text": f"Hey there <@{message['user']}>!"},
-                "accessory": {
-                    "type": "button",
-                    "text": {"type": "plain_text", "text":"Click Me"},
-                    "action_id": "button_click"
-                }
-            }
-        ],
-        text=f"Hey there <@{message['user']}>!"
-    )
-
-# アプリを起動します
-if __name__ == "__main__":
-    app.start(port=int(os.environ.get("PORT", 3000)))
-```
-
-`say()` の中の値を `blocks` という配列のオブジェクトに変えました。ブロックは Slack メッセージを構成するコンポーネントであり、テキストや画像、日付ピッカーなど、さまざまなタイプのブロックがあります。この例では `accessory` に `button` を持たせた「section」のブロックを、アプリからの応答に含めています。`blocks` を使用する場合、`text` は通知やアクセシビリティのためのフォールバックとなります。
-
-ボタンを含む `accessory` オブジェクトでは、`action_id` を指定していることがわかります。これは、ボタンを一意に示す識別子として機能します。これを使って、アプリをどのアクションに応答させるかを指定できます。
-
-> 💡 [Block Kit Builder](https://app.slack.com/block-kit-builder) を使用すると、インタラクティブなメッセージのプロトタイプを簡単に作成できます。自分自身やチームメンバーがメッセージのモックアップを作成し、生成される JSON をアプリに直接貼りつけることができます。
-
-アプリを再起動し、アプリが参加しているチャンネルで「hello」と入力すると、ボタン付きのメッセージが表示されるようになりました。ただし、ボタンをクリックしても、*まだ*何も起こりません。
-
-ハンドラーを追加して、ボタンがクリックされたときにフォローアップメッセージを送信するようにしてみましょう。
-
-```python
-import os
-from slack_bolt import App
-
-# ボットトークンと署名シークレットを使ってアプリを初期化します
-app = App(
-    token=os.environ.get("SLACK_BOT_TOKEN"),
-    signing_secret=os.environ.get("SLACK_SIGNING_SECRET")
-)
-
-# 'hello' を含むメッセージをリッスンします
-@app.message("hello")
-def message_hello(message, say):
-    # イベントがトリガーされたチャンネルへ say() でメッセージを送信します
-    say(
-        blocks=[
-            {
-                "type": "section",
-                "text": {"type": "mrkdwn", "text": f"Hey there <@{message['user']}>!"},
-                "accessory": {
-                    "type": "button",
-                    "text": {"type": "plain_text", "text":"Click Me"},
-                    "action_id": "button_click"
-                }
-            }
-        ],
-        text=f"Hey there <@{message['user']}>!"
-    )
-
-@app.action("button_click")
-def action_button_click(body, ack, say):
-    # アクションを確認したことを即時で応答します
-    ack()
-    # チャンネルにメッセージを投稿します
-    say(f"<@{body['user']['id']}> clicked the button")
-
-# アプリを起動します
-if __name__ == "__main__":
-    app.start(port=int(os.environ.get("PORT", 3000)))
-```
-
-`app.action()` を使って、先ほど命名した `button_click` という `action_id` をリッスンしています。アプリを再起動し、ボタンをクリックすると、アプリからの「clicked the button」というメッセージが新たに表示されるでしょう。

-### 次のステップ {#next-steps}
-はじめての [Bolt for Python アプリ](https://github.com/slackapi/bolt-python/tree/main/examples/getting_started)を構築することができました。🎉
-
-ここまでで基本的なアプリをセットアップして実行することはできたので、次は自分だけの Bolt アプリを作る方法を調べてみましょう。参考になりそうな記事をいくつかご紹介します。
-
-* [基本的な概念](/bolt-python/ja-jp/concepts#basic)について読む。Bolt アプリがアクセスできるさまざまメソッドや機能について知ることができます。
-* [`events()` メソッド](/bolt-python/ja-jp/concepts#event-listening)でボットがリッスンできるイベントをほかにも試してみる。すべてのイベントの一覧は [API サイト](https://api.slack.com/events)で確認できます。
-* Bolt では、アプリにアタッチされたクライアントから [Web API メソッドを呼び出す](/bolt-python/ja-jp/concepts#web-api)ことができます。API サイトに [220 以上のメソッド](https://api.slack.com/methods)を一覧しています。
-* [API サイト](https://api.slack.com/docs/token-types)でほかのタイプのトークンを確認する。アプリで実行したいアクションによって、異なるトークンが必要になる場合があります。HTTPの代わりにソケットモードを利用したい場合には、`connections:write` のスコープを追加した、追加のトークン (`xapp`) が必要です。

+# Acknowledging requests
 
 Actions, commands, shortcuts, options requests, and view submissions must **always** be acknowledged using the `ack()` function. This lets Slack know that the request was received so that it may update the Slack user interface accordingly.
 
-Depending on the type of request, your acknowledgement may be different. For example, when acknowledging a menu selection associated with an external data source, you would call `ack()` with a list of relevant [options](https://api.slack.com/reference/block-kit/composition-objects#option). When acknowledging a view submission, you may supply a `response_action` as part of your acknowledgement to [update the view](#update-views-on-submission). 
+Depending on the type of request, your acknowledgement may be different.

When acknowledging a view submission, you may supply a `response_action` as part of your acknowledgement to [update the view](/tools/bolt-python/concepts/view-submissions). 
 
 We recommend calling `ack()` right away before initiating any time-consuming processes such as fetching information from your database or sending a new message, since you only have 3 seconds to respond before Slack registers a timeout error.
 
-💡 When working in a FaaS / serverless environment, our guidelines for when to `ack()` are different. See the section on [Lazy listeners (FaaS)](#lazy-listeners) for more detail on this.

+# Listening & responding to actions
+
+Your app can listen and respond to user actions, like button clicks, and menu selects, using the `action` method.
+
+## Listening to actions
+
+Actions can be filtered on an `action_id` parameter of type `str` or `re.Pattern`. The `action_id` parameter acts as a unique identifier for interactive components on the Slack platform.
+
+You'll notice in all `action()` examples, `ack()` is used. It is required to call the `ack()` function within an action listener to acknowledge that the request was received from Slack. This is discussed in the [acknowledging requests guide](/tools/bolt-python/concepts/acknowledge).
+
+Refer to [the module document](https://docs.slack.dev/tools/bolt-python/reference/kwargs_injection/args.html) to learn the available listener arguments.
+
+```python
+# Your listener will be called every time a block element with the action_id "approve_button" is triggered
+@app.action("approve_button")
+def update_message(ack):
+    ack()
+    # Update the message to reflect the action
+```
+
+### Listening to actions using a constraint object
+
+You can use a constraints object to listen to `block_id`s and `action_id`s (or any combination of them). Constraints in the object can be of type `str` or `re.Pattern`.
+
+```python
+# Your function will only be called when the action_id matches 'select_user' AND the block_id matches 'assign_ticket'
+@app.action({
+    "block_id": "assign_ticket",
+    "action_id": "select_user"
+})
+def update_message(ack, body, client):
+    ack()
+
+    if "container" in body and "message_ts" in body["container"]:
+        client.reactions_add(
+            name="white_check_mark",
+            channel=body["channel"]["id"],
+            timestamp=body["container"]["message_ts"],
+        )
+```
+
+## Responding to actions
+
+There are two main ways to respond to actions. The first (and most common) way is to use `say()`, which sends a message back to the conversation where the incoming request took place.
+
+The second way to respond to actions is using `respond()`, which is a utility to use the `response_url` associated with the action.
+
+Refer to [the module document](https://docs.slack.dev/tools/bolt-python/reference/kwargs_injection/args.html) to learn the available listener arguments.
+
+```python
+# Your listener will be called every time an interactive component with the action_id “approve_button” is triggered
+@app.action("approve_button")
+def approve_request(ack, say):
+    # Acknowledge action request
+    ack()
+    say("Request approved 👍")
+```
+
+### Using `respond()` method
+
+Since `respond()` is a utility for calling the `response_url`, it behaves in the same way. You can pass [all the message payload properties](/messaging/#payloads) as keyword arguments along with optional properties like `response_type` (which has a value of `"in_channel"` or `"ephemeral"`), `replace_original`, `delete_original`, `unfurl_links`, and `unfurl_media`. With that, your app can send a new message payload that will be published back to the source of the original interaction.
+
+```python
+# Listens to actions triggered with action_id of “user_select”
+@app.action("user_select")
+def select_user(ack, action, respond):
+    ack()
+    respond(f"You selected <@{action['selected_user']}>")
+```

+# Adding agent features with Bolt for Python
+
+:::tip[Check out the Support Agent sample app]
+The code snippets throughout this guide are from our [Support Agent sample app](https://github.com/slack-samples/bolt-python-support-agent), Casey, which supports integration with Pydantic, Anthropic, and OpenAI. 
+
+View our [agent quickstart](/ai/agent-quickstart) to get up and running with Casey. Otherwise, read on for exploration and explanation of agent-focused Bolt features found within Casey.
+:::
+
+Your agent can utilize features applicable to messages throughout Slack, like [chat streaming](#text-streaming) and [feedback buttons](#adding-and-handling-feedback). They can also [utilize the `Assistant` class](/tools/bolt-python/concepts/assistant-class) for a side-panel view designed with AI in mind.
+
+If you're unfamiliar with using these feature within Slack, you may want to read the [API docs on the subject](/ai/). Then come back here to implement them with Bolt!
+
+---
+
+## Slack MCP Server {#slack-mcp-server}
+
+Casey can harness the [Slack MCP Server](https://docs.slack.dev/ai/slack-mcp-server/developing) when deployed via an HTTP Server with OAuth. 
+
+To enable the Slack MCP Server:
+
+1. Install [ngrok](https://ngrok.com/download) and start a tunnel:
+
+```sh
+ngrok http 3000
+```
+
+2. Copy the `https://*.ngrok-free.app` URL from the ngrok output.
+
+3. Update `manifest.json` for HTTP mode:
+   - Set `socket_mode_enabled` to `false`
+   - Replace `ngrok-free.app` with your ngrok domain (e.g. `YOUR_NGROK_SUBDOMAIN.ngrok-free.app`)
+
+4. Create a new local dev app:
+
+```sh
+slack install -E local
+```
+
+5. Enable MCP for your app:
+   - Run `slack app settings` to open your app's settings
+   - Navigate to **Agents & AI Apps** in the left-side navigation
+   - Toggle **Model Context Protocol** on
+
+6. Update your `.env` OAuth environment variables:
+   - Run `slack app settings` to open App Settings
+   - Copy **Client ID**, **Client Secret**, and **Signing Secret**
+   - Update `SLACK_REDIRECT_URI` in `.env` with your ngrok domain
+
+```sh
+SLACK_CLIENT_ID=YOUR_CLIENT_ID
+SLACK_CLIENT_SECRET=YOUR_CLIENT_SECRET
+SLACK_REDIRECT_URI=https://YOUR_NGROK_SUBDOMAIN.ngrok-free.app/slack/oauth_redirect
+SLACK_SIGNING_SECRET=YOUR_SIGNING_SECRET
+```
+
+7. Start the app:
+
+```sh
+slack run app_oauth.py
+```
+
+8. Click the install URL printed in the terminal to install the app to your workspace via OAuth.
+
+Your agent can now access the Slack MCP server!

+## Setting status {#setting-assistant-status}
+
+Your app can show actions are happening behind the scenes by setting its thread status. 
+
+```python
+def handle_app_mentioned(
+    set_status: SetStatus,
+    ...
+):
+    set_status(
+        status="Thinking...",

+            "Consulting the office goldfish…",
+            "Polishing up the response just for you…",
+            "Convincing the AI to stop overthinking…",
+        ],
+    )
+```
+
+---
+
+## Streaming messages {#text-streaming}
+
+You can have your app's messages stream in to replicate conventional agent behavior. Bolt for Python provides a `say_stream` utility as a listener argument available for `app.event` and `app.message` listeners. 
+
+The `say_stream` utility streamlines calling the Python Slack SDK's [`WebClient.chat_stream`](https://docs.slack.dev/tools/python-slack-sdk/reference/web/client.html#slack_sdk.web.client.WebClient.chat_stream) helper utility by sourcing parameter values from the relevant event payload.
+
+| Parameter | Value |
+|---|---| 
+| `channel_id` | Sourced from the event payload.
+| `thread_ts` | Sourced from the event payload. Falls back to the `ts` value if available.
+| `recipient_team_id` | Sourced from the event `team_id` (`enterprise_id` if the app is installed on an org).
+| `recipient_user_id` | Sourced from the `user_id` of the event.
+
+If neither a `channel_id` or `thread_ts` can be sourced, then the utility will be `None`.
+
+```python
+streamer = say_stream()
+streamer.append(markdown_text="Here's my response...")
+streamer.append(markdown_text="And here's more...")
+streamer.stop()
+```
+
+---
+
+## Adding and handling feedback {#adding-and-handling-feedback}
+
+You can use the [feedback buttons block element](/reference/block-kit/block-elements/feedback-buttons-element/) to allow users to immediately provide feedback regarding the app's responses. Here's what the feedback buttons look like from the Support Agent sample app:
+
+```py title=".../listeners/views/feedback_builder.py"
+from slack_sdk.models.blocks import (
+    Block,
+    ContextActionsBlock,
+    FeedbackButtonObject,
+    FeedbackButtonsElement,
+)
+
+
+def build_feedback_blocks() -> list[Block]:
+    """Build feedback blocks with thumbs up/down buttons."""
+    return [
+        ContextActionsBlock(
+            elements=[
+                FeedbackButtonsElement(
+                    action_id="feedback",
+                    positive_button=FeedbackButtonObject(
+                        text="Good Response",
+                        accessibility_label="Submit positive feedback on this response",
+                        value="good-feedback",
+                    ),
+                    negative_button=FeedbackButtonObject(
+                        text="Bad Response",
+                        accessibility_label="Submit negative feedback on this response",
+                        value="bad-feedback",
+                    ),
+                )
+            ]
+        )
+    ]
+```
+
+That feedback block is then rendered at the bottom of your app's message via the `say_stream` utility.
+
+```py
+...
+        # Stream response in thread with feedback buttons
+        streamer = say_stream()
+        streamer.append(markdown_text=result.output)
+        feedback_blocks = build_feedback_blocks()
+        streamer.stop(blocks=feedback_blocks)
+...
+```
+
+You can also add a response for when the user provides feedback. 
+
+```python title="...listeners/actions/feedback_button.py"
+from logging import Logger
+
+from slack_bolt import Ack, BoltContext
+from slack_sdk import WebClient
+
+
+def handle_feedback_button(
+    ack: Ack, body: dict, client: WebClient, context: BoltContext, logger: Logger
+):
+    """Handle thumbs up/down feedback on Casey's responses."""
+    ack()
+
+    try:
+        channel_id = context.channel_id
+        user_id = context.user_id
+        message_ts = body["message"]["ts"]
+        feedback_value = body["actions"][0]["value"]
+
+        if feedback_value == "good-feedback":
+            client.chat_postEphemeral(
+                channel=channel_id,
+                user=user_id,
+                thread_ts=message_ts,
+                text="Glad that was helpful! :tada:",
+            )
+        else:
+            client.chat_postEphemeral(
+                channel=channel_id,
+                user=user_id,
+                thread_ts=message_ts,
+                text="Sorry that wasn't helpful. :slightly_frowning_face: Try rephrasing your question or I can create a support ticket for you.",
+            )
+
+        logger.debug(
+            f"Feedback received: value={feedback_value}, message_ts={message_ts}"
+        )
+    except Exception as e:
+        logger.exception(f"Failed to handle feedback: {e}")

+## Onward: adding custom tools
+
+Casey comes with test tools and simulated systems. You can extend it with custom tools to make it a fully functioning Slack agent.
+
+In this example, we'll add a tool that makes live calls to check the GitHub status.
+
+1. Create `agent/tools/{tool-name}.py` and define the tool with the `@tool` decorator:
+
+```python title="agent/tools/check_github_status.py"
+from claude_agent_sdk import tool
+import httpx
+
+@tool(
+    name="check_github_status",
+    description="Check GitHub's current operational status",
+    input_schema={},
+)
+async def check_github_status_tool(args):
+    """Check if GitHub is operational."""
+    async with httpx.AsyncClient() as client:
+        response = await client.get("https://www.githubstatus.com/api/v2/status.json")
+        data = response.json()
+        status = data["status"]["indicator"]
+        description = data["status"]["description"]
+    
+    return {
+        "content": [
+            {
+                "type": "text",
+                "text": f"**GitHub Status** — {status}\n{description}",
+            }
+        ]
+    }
+```
+
+2. Import the tool in `agent/casey.py`:
+
+```python title="agent/casey.py"
+from agent.tools import check_github_status_tool
+```
+
+3. Register in `casey_tools_server`:
+
+```python title="agent/casey.py"
+casey_tools_server = create_sdk_mcp_server(
+    name="casey-tools",
+    version="1.0.0",
+    tools=[
+        check_github_status_tool,  # Add here
+        # ... other tools
+    ],
+)
+```
+
+4. Add to `CASEY_TOOLS`:
+
+```python title="agent/casey.py"
+CASEY_TOOLS = [
+    "check_github_status",  # Add here
+    # ... other tools
+]
+```
+
+Use this example as a jumping off point for building out an agent with the capabilities you need!

If you're implementing a custom adapter, you can make use of our [OAuth library](/tools/python-slack-sdk/oauth/), which is what Bolt for Python uses under the hood.
 
 Bolt for Python will create a **Redirect URL** `slack/oauth_redirect`, which Slack uses to redirect users after they complete your app's installation flow. You will need to add this **Redirect URL** in your app configuration settings under **OAuth and Permissions**. This path can be configured in the `OAuthSettings` argument described below.
 
 Bolt for Python will also create a `slack/install` route, where you can find an **Add to Slack** button for your app to perform direct installs of your app. If you need any additional authorizations (user tokens) from users inside a team when your app is already installed or a reason to dynamically generate an install URL, you can pass your own custom URL generator to `oauth_settings` as `authorize_url_generator`.

+# Custom Steps dynamic options for Workflow Builder
+
+## Background {#background}
+
+[Legacy steps from apps](/changelog/2023-08-workflow-steps-from-apps-step-back) previously enabled Slack apps to create and process custom workflow steps, which could then be shared and used by anyone in Workflow Builder. To support your transition away from them, custom steps used as dynamic options are available. These allow you to use data defined when referencing the step in Workflow Builder as inputs to the step.
+
+## Example use case {#use-case}
+
+Let's say a builder wants to add a custom step in Workflow Builder that creates an issue in an external issue-tracking system. First, they'll need to specify a project. Once a project is selected, a project-specific list of fields can be presented to them to choose from when creating the issue.
+
+As a developer, dynamic options allow you to supply data to input parameters of custom steps so that you can provide builders with varying sets of fields based on the builders' selections.
+
+In this example, the primary step would invoke a separate project selection step that retrieves the list of available projects. The builder-selected item from the  retrieved list would then be used as the input to the secondary issue creation step.
+
+There are two parts necessary for Slack apps to support dynamic options: custom step definitions, and handling custom step dynamic options. We'll take a look at both in the following sections.
+
+## Custom step definitions {#custom-step-definitions}
+
+When defining an input to a custom step intended to be dynamic (rather than explicitly defining a set of input parameters up front), you'll define a `dynamic_options` property that points to another custom step designed to return the set of dynamic elements once this step is added to a workflow from Workflow Builder.
+
+An input parameter for a custom step can reference a different custom step that defines what data is available for it to return. One Slack app could even use another Slack app’s custom step to define dynamic options for one of its inputs.
+
+The following code snippet from our issue creation example discussed above shows a `create-issue` custom step that will be used as a workflow step. Another custom step, the `get-projects` step, will dynamically populate the project input parameter to be configured by a builder. This `get-projects` step provides an `array` containing projects fetched dynamically from the external issue-tracking system.
+
+```js
+    "functions": {
+        "create-issue": {
+            "title": "Create Issue",
+            "description": "",
+            "input_parameters": {
+                "support_channel": {
+                    "type": "slack#/types/channel_id",
+                    "title": "Support Channel",
+                    "description": "",
+                    "name": "support_channel"
+                },
+                "project": {
+                    "type": "string",
+                    "title": "Project",
+                    "description": "A project from the issue tracking system",
+                    "is_required": true,
+                    "dynamic_options": {
+                        "function": "#/functions/get-projects",
+                        "inputs": {}
+                    }
+                },
+            },
+            "output_parameters": {}
+        },
+        "get-projects": {
+            "title": "Get Projects",
+            "description": "Get the available project from the issue tracking system",
+            "input_parameters": {},
+            "output_parameters": {
+                "options": {
+                    "type": "slack#/types/options_select",
+                    "title": "Project Options", 
+                }
+            }
+        }
+    },
+```
+### Defining the `function` and `inputs` attributes {#define-attributes}
+
+Defining the `function` and `inputs` attributes of the `dynamic_options` property would look as follows: 
+
+```
+"dynamic_options": {
+    "function": "#/functions/get-projects",
+    "inputs": {}
+}
+```
+
+The `function` attribute specifies the step reference used to resolve the options of the input parameter. For example: `"#/functions/get-projects"`.
+
+The `inputs` attribute defines the parameters to be passed as inputs to the step referenced by the `function` attribute. For example:
+
+```
+"inputs": {
+    "selected_user_id": {
+        "value": "{{input_parameters.user_id}}"
+    },
+    "query": {
+        "value": "{{client.query}}"
+    }
+}
+```
+
+The following format can be used to reference any input parameter defined by the step: `{{input_parameters.<PARAMETER_NAME>}}`.
+
+In addition, the `{{client.query}}` parameter can be used as a placeholder for an input value. The `{{client.builder_context}}` parameter will inject the [`slack#/types/user_context`](/tools/deno-slack-sdk/reference/slack-types/#usercontext) of the user building the workflow as the value to the input parameter.
+
+### Types of dynamic options UIs {#dynamic-option-UIs}
+
+The above example demonstrates one possible UI to be rendered for builders: a single-select drop-down menu of dynamic options. However, dynamic options in Workflow Builder can be rendered in one of two ways: as a drop-down menu (single-select or multi-select), or as a set of fields.
+
+The type is dictated by the output parameter of the custom step used as a dynamic option. In order to use a custom step in a dynamic option context, its output must adhere to a defined interface, that is, it must have an `options` parameter of type [`options_select`](/tools/deno-slack-sdk/reference/slack-types#options_select) or [`options_field`](/tools/deno-slack-sdk/reference/slack-types#options_field), as shown in the following code snippet.
+
+```js
+"output_parameters": {
+    "options": {
+        "type": "slack#/types/options_select" or "slack#/types/options_field",
+        "title": "Custom Options",
+        "description": "Options to be used in a dynamic context",
+    }
+   ...
+}
+```
+
+#### Drop-down menus {#drop-down}
+
+Your dynamic input parameter can be rendered as a drop-down menu, which will use the options obtained from a custom step with an `options` output parameter of the type [`options_select`](/tools/deno-slack-sdk/reference/slack-types#options_select).
+
+The drop-down menu UI component can be rendered in two ways: single-select, or multi-select. To render the dynamic input as a single-select menu, the input parameter defining the dynamic option must be of the type [`string`](/tools/deno-slack-sdk/reference/slack-types#string).
+
+```js
+"step-with-dynamic-input": {
+    "title": "Step that uses a dynamic input",
+    "description": "This step uses a dynamic input rendered as a single-select menu",
+    "input_parameters": {
+        "dynamic_single_select": {
+            "type": "string", // this must be of type string for single-select
+            "title": "dynamic single select drop-down menu",
+            "description": "A dynamically-populated single-select drop-down menu",
+            "is_required": true,
+            "dynamic_options": {
+                "function": "#/functions/get-options",
+                "inputs": {},
+            },
+        }
+    },
+    "output_parameters": {}
+}
+```
+
+To render the dynamic input as a multi-select menu, the input parameter defining the dynamic option must be of the type [`array`](/tools/deno-slack-sdk/reference/slack-types#array), and its `items` must be of type [`string`](/tools/deno-slack-sdk/reference/slack-types#string).
+
+```js
+"step-with-dynamic-input": {
+    "title": "Step that uses a dynamic input",
+    "description": "This step uses a dynamic input rendered as a multi-select menu",
+    "input_parameters": {
+        "dynamic_multi_select": {
+            "type": "array", // this must be of type array for multi-select
+            "items": {
+                "type": "string"
+            },
+            "title": "dynamic single select drop-down menu",
+            "description": "A dynamically-populated multi-select drop-down menu",
+            "dynamic_options": {
+                "function": "#/functions/get-options",
+                "inputs": {},
+            },
+        }
+    },
+    "output_parameters": {}
+}
+```
+
+#### Fields {#fields}
+
+In the code snippet below, the input parameter is rendered as a set of fields with keys and values. The option fields are obtained from a custom step with an `options` output parameter of type [`options_field`](/tools/deno-slack-sdk/reference/slack-types#options_field).
+
+The input parameter that defines the dynamic option must be of type [`object`](/tools/deno-slack-sdk/reference/slack-types#object), as the completed set of fields in Workflow Builder will be passed to the custom step as an [untyped object](/tools/deno-slack-sdk/reference/slack-types#untyped-object) during workflow execution.
+
+```js
+"test-field-dynamic-options": {
+    "title": "Test dynamic field options",
+    "description": "",
+    "input_parameters": {
+        "dynamic_fields": {
+            "type": "object",
+            "title": "Dynamic custom field options",
+            "description": "A dynamically-populated section of input fields",
+            "dynamic_options": {
+                "function": "#/functions/get-field-options",
+                "inputs": {}
+                "selection_type": "key-value",
+            }
+        }
+    },
+    "output_parameters": {}
+}
+```
+
+### Dynamic option types {#dynamic-option-types}
+
+As mentioned earlier, in order to use a custom step as a dynamic option, its output must adhere to a defined interface: it must have an `options` output parameter of the type either [`options_select`](/tools/deno-slack-sdk/reference/slack-types#options_select) or [`options_field`](/tools/deno-slack-sdk/reference/slack-types#options_field). 
+
+To take a look at these in more detail, refer to our [Options Slack type](/tools/deno-slack-sdk/reference/slack-types#options) documentation.
+
+## Dynamic options handler {#dynamic-option-handler}
+
+Each custom step defined in the manifest needs a corresponding handler in your Slack app. Although implemented similarly to existing function execution event handlers, there are two key differences between regular custom step invocations and those used for dynamic options:
+
+* The custom step must have an `options` output parameter that is of type [`options_select`](/tools/deno-slack-sdk/reference/slack-types#options_select) or [`options_field`](/tools/deno-slack-sdk/reference/slack-types#options_field).
+* The [`function_executed`](/reference/events/function_executed) event must be handled synchronously. This optimizes the response time of returned dynamic options and provides a crisp builder experience.
+
+### Asynchronous event handling {#async}
+
+By default, the Bolt family of frameworks handles `function_executed` events asynchronously. 
+
+For example, the various modal-related API methods provide two ways to update a view: synchronously using a `response_action` HTTP response, or asynchronously using a separate HTTP API call. Using the asynchronous approach allows developers to handle events free of timeouts, but this isn't desired for dynamic options as it introduces delays and violates our stated goal of providing a crisp builder experience.
+
+### Synchronous event handling {#sync}
+
+Dynamic options support synchronous handling of `function_executed` events. By ensuring that the function execution’s state is complete with output parameters provided before responding to the `function_executed` event, Slack can quickly provide Workflow Builder with the requisite dynamic options.
+
+### Implementation {#implementation}
+
+To optimize the response time of dynamic options, you must acknowledge the incoming event after calling the [`function.completeSuccess`](/reference/methods/functions.completeSuccess) or [`function.completeError`](/reference/methods/functions.completeError) API methods, minimizing asynchronous latency. The `function.completeSuccess` and `function.completeError` API methods are invoked in the complete and fail helper functions. ([For example](https://github.com/slackapi/bolt-python?tab=readme-ov-file#making-things-happen)).
+
+A new `auto_acknowledge` flag allows you more granular control over whether specific event handlers should operate in synchronous or asynchronous response modes in order to enable a smooth dynamic options experience.
+
+#### Example {#bolt-py}
+
+In [Bolt for Python](https://docs.slack.dev/tools/bolt-python/), you can set `auto_acknowledge=False` on a specific function decorator. This allows you to manually control when the `ack()` event acknowledgement helper function is executed. It flips Bolt to synchronous `function_executed` event handling mode for the specific handler. 
+
+```py
+@app.function("get-projects", auto_acknowledge=False)
+def handle_get_projects(ack: Ack, complete: Complete):
+    try:
+        complete(
+            outputs={
+                "options": [
+                    {
+                        "text": {
+                            "type": "plain_text",
+                            "text": "Secret Squirrel Project",
+                        },
+                        "value": "p1",
+                    },
+                    {
+                        "text": {
+                            "type": "plain_text",
+                            "text": "Public Kangaroo Project",
+                        },
+                        "value": "p2",
+                    },
+                ]
+            }
+        )
+   finally:
+        ack()

+
+# Listening and responding to custom steps
+
+Your app can use the `function()` method to listen to incoming [custom step requests](/workflows/workflow-steps). Custom steps are used in Workflow Builder to build workflows. The method requires a step `callback_id` of type `str`. This `callback_id` must also be defined in your [Function](/reference/app-manifest#functions) definition. Custom steps must be finalized using the `complete()` or `fail()` listener arguments to notify Slack that your app has processed the request.
+
+* `complete()` requires **one** argument: `outputs` of type `dict`. It ends your custom step **successfully** and provides a dictionary containing the outputs of your custom step as per its definition.
+* `fail()` requires **one** argument: `error` of type `str`. It ends your custom step **unsuccessfully** and provides a message containing information regarding why your custom step failed.
+
+You can reference your custom step's inputs using the `inputs` listener argument of type `dict`.
+
+Refer to [the module document](https://docs.slack.dev/tools/bolt-python/reference/kwargs_injection/args.html) to learn about the available listener arguments.
+
+```python
+# This sample custom step formats an input and outputs it
+@app.function("sample_custom_step")
+def sample_step_callback(inputs: dict, fail: Fail, complete: Complete):
+    try:
+        message = inputs["message"]
+        complete(
+            outputs={
+                "message": f":wave: You submitted the following message: \n\n>{message}"
+            }

+
+### Listening to custom step interactivity events
+
+Your app's custom steps may create interactivity points for users, for example: Post a message with a button.
+
+If such interaction points originate from a custom step execution, the events sent to your app representing the end-user interaction with these points are considered to be _function-scoped interactivity events_. These interactivity events can be handled by your app using the same concepts we covered earlier, such as [Listening to actions](/tools/bolt-python/concepts/actions).
+
+_function-scoped interactivity events_ will contain data related to the custom step (`function_executed` event) they were spawned from, such as custom step `inputs` and access to `complete()` and `fail()` listener arguments.
+
+Your app can skip calling `complete()` or `fail()` in the `function()` handler method if the custom step creates an interaction point that requires user interaction before the step can end. However, in the relevant interactivity handler method, your app must invoke `complete()` or `fail()` to notify Slack that the custom step has been processed.
+
+You’ll notice in all interactivity handler examples, `ack()` is used. It is required to call the `ack()` function within an interactivity listener to acknowledge that the request was received from Slack. This is discussed in the [acknowledging requests section](/tools/bolt-python/concepts/acknowledge).
+
+```python
+# This sample custom step posts a message with a button
+@app.function("custom_step_button")
+def sample_step_callback(inputs, say, fail):
+    try:
+        say(
+            channel=inputs["user_id"],  # sending a DM to this user
+            text="Click the button to signal the step completion",
+            blocks=[
+                {
+                    "type": "section",

+                }

+
+# Your listener will be called every time a block element with the action_id "sample_click" is triggered
+@app.action("sample_click")
+def handle_sample_click(ack, body, context, client, complete, fail):
+    ack()
+    try:
+        # Since the button no longer works, we should remove it
+        client.chat_update(
+            channel=context.channel_id,
+            ts=body["message"]["ts"],
+            text="Congrats! You clicked the button",
+        )

 If an error occurs in a listener, you can handle it directly using a try/except block. Errors associated with your app will be of type `BoltError`. Errors associated with calling Slack APIs will be of type `SlackApiError`.

 By default, Bolt will log information from your app to the output destination. After you've imported the `logging` module, you can customize the root log level by passing the `level` parameter to `basicConfig()`. The available log levels in order of least to most severe are `debug`, `info`, `warning`, `error`, and `critical`.
 
 Outside of a global context, you can also log a single message corresponding to a specific level. Because Bolt uses Python’s [standard logging module](https://docs.python.org/3/library/logging.html), you can use any its features.

+`message()` accepts an argument of type `str` or `re.Pattern` object that filters out any messages that don't match the pattern.

+# Sending messages
+
+Within your listener function, `say()` is available whenever there is an associated conversation (for example, a conversation where the event or action which triggered the listener occurred). `say()` accepts a string to post simple messages and JSON payloads to send more complex messages. The message payload you pass in will be sent to the associated conversation.
+
+In the case that you'd like to send a message outside of a listener or you want to do something more advanced (like handle specific errors), you can call `client.chat_postMessage` [using the client attached to your Bolt instance](/tools/bolt-python/concepts/web-api).
+
+Refer to [the module document](https://docs.slack.dev/tools/bolt-python/reference/kwargs_injection/args.html) to learn the available listener arguments.
+
+```python
+# Listens for messages containing "knock knock" and responds with an italicized "who's there?"
+@app.message("knock knock")
+def ask_who(message, say):
+    say("_Who's there?_")
+```
+
+## Sending a message with blocks
+
+`say()` accepts more complex message payloads to make it easy to add functionality and structure to your messages.
+
+To explore adding rich message layouts to your app, read through [the guide on our API site](/messaging/#structure) and look through templates of common app flows [in the Block Kit Builder](https://api.slack.com/tools/block-kit-builder?template=1).
+
+```python
+# Sends a section block with datepicker when someone reacts with a 📅 emoji
+@app.event("reaction_added")
+def show_datepicker(event, say):
+    reaction = event["reaction"]
+    if reaction == "calendar":
+        blocks = [{
+          "type": "section",
+          "text": {"type": "mrkdwn", "text": "Pick a date for me to remind you"},
+          "accessory": {
+              "type": "datepicker",
+              "action_id": "datepicker_remind",
+              "initial_date": "2020-05-04",
+              "placeholder": {"type": "plain_text", "text": "Select a date"}
+          }

+        say(

+            text="Pick a date for me to remind you"
+        )
+```
+
+## Streaming messages {#streaming-messages}
+
+You can have your app's messages stream in to replicate conventional agent behavior. Bolt for Python provides a `say_stream` utility as a listener argument available for `app.event` and `app.message` listeners. 
+
+The `say_stream` utility streamlines calling the Python Slack SDK's [`WebClient.chat_stream`](https://docs.slack.dev/tools/python-slack-sdk/reference/web/client.html#slack_sdk.web.client.WebClient.chat_stream) helper utility by sourcing parameter values from the relevant event payload.
+
+| Parameter | Value |
+|---|---| 
+| `channel_id` | Sourced from the event payload.
+| `thread_ts` | Sourced from the event payload. Falls back to the `ts` value if available.
+| `recipient_team_id` | Sourced from the event `team_id` (`enterprise_id` if the app is installed on an org).
+| `recipient_user_id` | Sourced from the `user_id` of the event.
+
+If neither a `channel_id` or `thread_ts` can be sourced, then the utility will be `None`.
+
+For information on calling the `chat_*Stream` API methods directly, see the [_Sending streaming messages_](/tools/python-slack-sdk/web#sending-streaming-messages) section of the Python Slack SDK docs.
+
+### Example {#example}
+
+```py
+import os
+
+from slack_bolt import App, SayStream
+from slack_bolt.adapter.socket_mode import SocketModeHandler
+from slack_sdk import WebClient
+
+app = App(token=os.environ.get("SLACK_BOT_TOKEN"))
+
+@app.event("app_mention")
+def handle_app_mention(client: WebClient, say_stream: SayStream):
+  stream = say_stream()
+  stream.append(markdown_text="Someone rang the bat signal!")
+  stream.stop()
+
+@app.message("")
+def handle_message(client: WebClient, say_stream: SayStream):
+  stream = say_stream()
+
+  stream.append(markdown_text="Let me consult my *vast knowledge database*...)
+  stream.stop()
+
+if __name__ == "__main__":
+  SocketModeHandler(app, os.environ.get("SLACK_APP_TOKEN")).start()
+```
+
+#### Adding feedback buttons after a stream
+
+You can pass a [feedback buttons](/reference/block-kit/block-elements/feedback-buttons-element) block element to `stream.stop` to provide feedback buttons to the user at the bottom of the message. Interaction with these buttons will send a block action event to your app to receive the feedback.
+
+```py
+stream.stop(blocks=feedback_block)
+```
+
+```py
+def create_feedback_block() -> List[Block]:
+    blocks: List[Block] = [
+        ContextActionsBlock(
+            elements=[
+                FeedbackButtonsElement(

+The `shortcut()` method supports both [global shortcuts](/interactivity/implementing-shortcuts#global) and [message shortcuts](/interactivity/implementing-shortcuts#messages).
 
 Shortcuts are invokable entry points to apps. Global shortcuts are available from within search and text composer area in Slack. Message shortcuts are available in the context menus of messages. Your app can use the `shortcut()` method to listen to incoming shortcut requests. The method requires a `callback_id` parameter of type `str` or `re.Pattern`.
 
 Shortcuts must be acknowledged with `ack()` to inform Slack that your app has received the request.
 
-Shortcuts include a `trigger_id` which an app can use to [open a modal](#creating-modals) that confirms the action the user is taking.
+Shortcuts include a `trigger_id` which an app can use to [open a modal](/tools/bolt-python/concepts/opening-modals) that confirms the action the user is taking.
 
 When setting up shortcuts within your app configuration, as with other URLs, you'll append `/slack/events` to your request URL.
 
-⚠️ Note that global shortcuts do **not** include a channel ID. If your app needs access to a channel ID, you may use a [`conversations_select`](https://api.slack.com/reference/block-kit/block-elements#conversation_select) element within a modal. Message shortcuts do include a channel ID.

+# Using the Assistant class
+
+:::info[Some features within this guide require a paid plan]
+If you don't have a paid workspace for development, you can join the [Developer Program](https://api.slack.com/developer-program) and provision a sandbox with access to all Slack features for free.
+:::
+
+The `Assistant` class can be used to handle the incoming events expected from a user interacting with an app in Slack that has the Agents & AI Apps feature enabled. 
+
+A typical flow would look like:
+
+1. [The user starts a thread](#handling-new-thread). The `Assistant` class handles the incoming [`assistant_thread_started`](/reference/events/assistant_thread_started) event.
+2. [The thread context may change at any point](#handling-thread-context-changes). The `Assistant` class can handle any incoming [`assistant_thread_context_changed`](/reference/events/assistant_thread_context_changed) events. The class also provides a default `context` store to keep track of thread context changes as the user moves through Slack.
+3. [The user responds](#handling-user-response). The `Assistant` class handles the incoming [`message.im`](/reference/events/message.im) event. 
+
+
+```python
+assistant = Assistant()
+
+# This listener is invoked when a human user opened an assistant thread
+@assistant.thread_started
+def start_assistant_thread(
+    say: Say,
+    get_thread_context: GetThreadContext,
+    set_suggested_prompts: SetSuggestedPrompts,
+    logger: logging.Logger,
+):
+    try:
+        ...
+
+# This listener is invoked when the human user sends a reply in the assistant thread
+@assistant.user_message
+def respond_in_assistant_thread(
+    client: WebClient,
+    context: BoltContext,
+    get_thread_context: GetThreadContext,
+    logger: logging.Logger,
+    payload: dict,
+    say: Say,
+    set_status: SetStatus,
+):
+    try:
+        ...
+
+# Enable this assistant middleware in your Bolt app
+app.use(assistant)
+```
+
+:::info[Consider the following]
+You _could_ go it alone and [listen](/tools/bolt-python/concepts/event-listening) for the `assistant_thread_started`, `assistant_thread_context_changed`, and `message.im` events in order to implement the AI features in your app. That being said, using the `Assistant` class will streamline the process. And we already wrote this nice guide for you!
+:::
+
+While the `assistant_thread_started` and `assistant_thread_context_changed` events do provide Slack-client thread context information, the `message.im` event does not. Any subsequent user message events won't contain thread context data. For that reason, Bolt not only provides a way to store thread context — the `threadContextStore` property — but it also provides a `DefaultThreadContextStore` instance that is utilized by default. This implementation relies on storing and retrieving [message metadata](/messaging/message-metadata/) as the user interacts with the app. 
+
+If you do provide your own `threadContextStore` property, it must feature `get` and `save` methods.
+
+:::tip[Refer to the [reference docs](https://docs.slack.dev/tools/bolt-python/reference/kwargs_injection/args.html) to learn the available listener arguments.]
+:::
+
+## Configuring your app to support the `Assistant` class {#configuring-assistant-class}
+
+1. Within [App Settings](https://api.slack.com/apps), enable the **Agents & AI Apps** feature.
+
+2. Within the App Settings **OAuth & Permissions** page, add the following scopes: 
+  * [`assistant:write`](/reference/scopes/assistant.write)
+  * [`chat:write`](/reference/scopes/chat.write)
+  * [`im:history`](/reference/scopes/im.history)
+
+3. Within the App Settings **Event Subscriptions** page, subscribe to the following events: 
+  * [`assistant_thread_started`](/reference/events/assistant_thread_started)
+  * [`assistant_thread_context_changed`](/reference/events/assistant_thread_context_changed)
+  * [`message.im`](/reference/events/message.im)
+
+## Handling a new thread {#handling-new-thread}
+
+When the user opens a new thread with your AI-enabled app, the [`assistant_thread_started`](/reference/events/assistant_thread_started) event will be sent to your app.
+
+:::tip[When a user opens an app thread while in a channel, the channel info is stored as the thread's `AssistantThreadContext` data.] 
+
+You can grab that info by using the `get_thread_context` utility, as subsequent user message event payloads won't include the channel info.
+:::
+
+```python
+assistant = Assistant()
+
+@assistant.thread_started
+def start_assistant_thread(
+    say: Say,
+    get_thread_context: GetThreadContext,
+    set_suggested_prompts: SetSuggestedPrompts,
+    logger: logging.Logger,
+):
+    try:
+        say("How can I help you?")
+
+        prompts: List[Dict[str, str]] = [
+            {
+                "title": "Suggest names for my Slack app",
+                "message": "Can you suggest a few names for my Slack app? The app helps my teammates better organize information and plan priorities and action items.",
+            },
+        ]
+
+        thread_context = get_thread_context()
+        if thread_context is not None and thread_context.channel_id is not None:

+        logger.exception(f"Failed to handle an assistant_thread_started event: {e}", e)
+        say(f":warning: Something went wrong! ({e})")
+```
+
+You can send more complex messages to the user — see [Sending Block Kit alongside messages](#block-kit-interactions) for more info. 
+
+## Handling thread context changes {#handling-thread-context-changes}
+
+When the user switches channels, the [`assistant_thread_context_changed`](/reference/events/assistant_thread_context_changed) event will be sent to your app. 
+
+If you use the built-in `Assistant` middleware without any custom configuration, the updated context data is automatically saved as [message metadata](/messaging/message-metadata/) of the first reply from the app. 
+
+As long as you use the built-in approach, you don't need to store the context data within a datastore. The downside of this default behavior is the overhead of additional calls to the Slack API. These calls include those to `conversations.history`, which are used to look up the stored message metadata that contains the thread context (via `get_thread_context`). 
+
+To store context elsewhere, pass a custom `AssistantThreadContextStore` implementation to the `Assistant` constructor. We provide `FileAssistantThreadContextStore`, which is a reference implementation that uses the local file system. Since this reference implementation relies on local files, it's not advised for use in production. For production apps, we recommend creating a class that inherits `AssistantThreadContextStore`.
+
+```python
+from slack_bolt import FileAssistantThreadContextStore
+assistant = Assistant(thread_context_store=FileAssistantThreadContextStore())
+```
+
+## Handling the user response {#handling-user-response}
+
+When the user messages your app, the [`message.im`](/reference/events/message.im) event will be sent to your app.
+
+Messages sent to the app do not contain a [subtype](/reference/events/message#subtypes) and must be deduced based on their shape and any provided [message metadata](/messaging/message-metadata/).
+
+There are three utilities that are particularly useful in curating the user experience:
+* [`say`](https://docs.slack.dev/tools/bolt-python/reference/#slack_bolt.Say)
+* [`setTitle`](https://docs.slack.dev/tools/bolt-python/reference/#slack_bolt.SetTitle)
+* [`setStatus`](https://docs.slack.dev/tools/bolt-python/reference/#slack_bolt.SetStatus)
+
+Within the `setStatus` utility, you can cycle through strings passed into a `loading_messages` array.
+
+```python
+# This listener is invoked when the human user sends a reply in the assistant thread
+@assistant.user_message
+def respond_in_assistant_thread(
+    client: WebClient,
+    context: BoltContext,
+    get_thread_context: GetThreadContext,
+    logger: logging.Logger,
+    payload: dict,
+    say: Say,
+    set_status: SetStatus,

+    try:
+        channel_id = payload["channel"]
+        team_id = payload["team"]

+                "Consulting the office goldfish…",
+                "Convincing the AI to stop overthinking…",
+            ],
+        )
+
+        # Collect the conversation history with this user
+        replies = client.conversations_replies(
+            channel=context.channel_id,
+            ts=context.thread_ts,
+            oldest=context.thread_ts,
+            limit=10,
+        )
+        messages_in_thread: List[Dict[str, str]] = []
+        for message in replies["messages"]:
+            role = "user" if message.get("bot_id") is None else "assistant"
+            messages_in_thread.append({"role": role, "content": message["text"]})
+
+        returned_message = call_llm(messages_in_thread)
+
+        # Post the result in the assistant thread
+        say(text=returned_message)
+
+    except Exception as e:
+        logger.exception(f"Failed to respond to an inquiry: {e}")
+        # Don't forget sending a message telling the error
+        # Without this, the status 'is typing...' won't be cleared, therefore the end-user is unable to continue the chat
+        say(f":warning: Sorry, something went wrong during processing your request (error: {e})")
+
+# Enable this assistant middleware in your Bolt app
+app.use(assistant)
+```
+
+## Sending Block Kit alongside messages {#block-kit-interactions}
+
+For advanced use cases, Block Kit buttons may be used instead of suggested prompts, as well as the sending of messages with structured [metadata](/messaging/message-metadata/) to trigger subsequent interactions with the user.
+
+For example, an app can display a button such as "Summarize the referring channel" in the initial reply. When the user clicks the button and submits detailed information (such as the number of messages, days to check, purpose of the summary, etc.), the app can handle that information and post a message that describes the request with structured metadata.
+
+By default, apps can't respond to their own bot messages (Bolt prevents infinite loops by default). However, if you pass `ignoring_self_assistant_message_events_enabled=False` to the `App` constructor and add a `bot_message` listener to your `Assistant` middleware, your app can continue processing the request as shown below:
+
+```python
+app = App(
+    token=os.environ["SLACK_BOT_TOKEN"],
+    # This must be set to handle bot message events
+    ignoring_self_assistant_message_events_enabled=False,
+)
+
+assistant = Assistant()
+
+@assistant.thread_started
+def start_assistant_thread(say: Say):
+    say(
+        text=":wave: Hi, how can I help you today?",

+
+# Creating an app with Bolt for Python
+
+This guide is meant to walk you through getting up and running with a Slack app using Bolt for Python. Along the way, we’ll create a new Slack app, set up your local environment, and develop an app that listens and responds to messages from a Slack workspace.
+
+When you're finished, you'll have created the [Getting Started app](https://github.com/slackapi/bolt-python/tree/main/examples/getting_started) to run, modify, and make your own. ⚡️
+ 
+---
+
+### Create a new app {#create-an-app}
+First thing's first: before you start developing with Bolt, you'll want to [create a Slack app](https://api.slack.com/apps/new).
+
+:::tip[A place to test and learn]  
+
+We recommend using a workspace where you won't disrupt real work getting done — [you can create a new one for free](https://slack.com/get-started#create).
+
+:::
+
+After you fill out an app name (_you can change it later_) and pick a workspace to install it to, hit the `Create App` button and you'll land on your app's **Basic Information** page.
+
+This page contains an overview of your app in addition to important credentials you'll need later. 
+
+![Basic Information page](/img/bolt-python/basic-information-page.png "Basic Information page")
+
+Look around, add an app icon and description, and then let's start configuring your app 🔩
+
+---
+
+### Tokens and installing apps {#tokens-and-installing-apps}
+Slack apps use [OAuth to manage access to Slack's APIs](/authentication/installing-with-oauth). When an app is installed, you'll receive a token that the app can use to call API methods.
+
+There are three main token types available to a Slack app: user (`xoxp`), bot (`xoxb`), and app-level (`xapp`) tokens. 
+- [User tokens](/authentication/tokens#user) allow you to call API methods on behalf of users after they install or authenticate the app. There may be several user tokens for a single workspace. 
+- [Bot tokens](/authentication/tokens#bot) are associated with bot users, and are only granted once in a workspace where someone installs the app. The bot token your app uses will be the same no matter which user performed the installation. Bot tokens are the token type that _most_ apps use.
+- [App-level tokens](/authentication/tokens#app-level) represent your app across organizations, including installations by all individual users on all workspaces in a given organization and are commonly used for creating WebSocket connections to your app.
+
+We're going to use bot and app-level tokens for this guide.
+
+1. Navigate to **OAuth & Permissions** on the left sidebar and scroll down to the **Bot Token Scopes** section. Click **Add an OAuth Scope**.
+
+2. For now, we'll just add one scope: [`chat:write`](/reference/scopes/chat.write). This grants your app the permission to post messages in channels it's a member of.
+
+3. Scroll up to the top of the **OAuth & Permissions** page and click **Install App to Workspace**. You'll be led through Slack's OAuth UI, where you should allow your app to be installed to your development workspace.
+
+4. Once you authorize the installation, you'll land on the **OAuth & Permissions** page and see a **Bot User OAuth Access Token**. 
+
+![OAuth Tokens](/img/bolt-python/bot-token.png "Bot OAuth Token")
+
+5. Head over to **Basic Information** and scroll down under the App Token section and click **Generate Token and Scopes** to generate an app-level token. Add the `connections:write` scope to this token and save the generated `xapp` token.
+
+6. Navigate to **Socket Mode** on the left side menu and toggle to enable. 
+
+:::tip[Not sharing is sometimes caring]
+
+Treat your tokens like passwords and [keep them safe](/security). Your app uses tokens to post and retrieve information from Slack workspaces.
+
+:::
+
+---
+
+### Setting up your project {#setting-up-your-project}
+
+With the initial configuration handled, it's time to set up a new Bolt project. This is where you'll write the code that handles the logic for your app.
+
+If you don’t already have a project, let’s create a new one. Create an empty directory:
+
+```sh
+$ mkdir first-bolt-app
+$ cd first-bolt-app
+```
+
+Next, we recommend using a [Python virtual environment](https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/#creating-a-virtual-environment) to manage your project's dependencies. This is a great way to prevent conflicts with your system's Python packages. Let's create and activate a new virtual environment with [Python 3.7 or later](https://www.python.org/downloads/):
+
+```sh
+$ python3 -m venv .venv
+$ source .venv/bin/activate
+$ pip install -r requirements.txt
+```
+
+We can confirm that the virtual environment is active by checking that the path to `python3` is _inside_ your project ([a similar command is available on Windows](https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/#activating-a-virtual-environment)):
+
+```sh
+$ which python3
+# Output: /path/to/first-bolt-app/.venv/bin/python3
+```
+
+Before we install the Bolt for Python package to your new project, let's save the **bot token** and **app-level token** that were generated when you configured your app. 
+
+1. **Copy your bot (xoxb) token from the OAuth & Permissions page** and store it in a new environment variable. The following example works on Linux and macOS; but [similar commands are available on Windows](https://superuser.com/questions/212150/how-to-set-env-variable-in-windows-cmd-line/212153#212153).
+
+```sh
+$ export SLACK_BOT_TOKEN=xoxb-<your-bot-token>
+```
+
+2. **Copy your app-level (xapp) token from the Basic Information page** and then store it in a new environment variable.
+
+```sh
+$ export SLACK_APP_TOKEN=<your-app-level-token>
+```
+
+:::warning[Keep it secret. Keep it safe.]
+
+Remember to keep your tokens secure. At a minimum, you should avoid checking them into public version control, and access them via environment variables as we've done above. Check out the API documentation for more on [best practices for app security](/security).
+
+:::
+
+Now, let's create your app. Install the `slack_bolt` Python package to your virtual environment using the following command:
+
+```sh
+$ pip install slack_bolt
+```
+
+Create a new file called `app.py` in this directory and add the following code:
+
+```python
+import os
+from slack_bolt import App
+from slack_bolt.adapter.socket_mode import SocketModeHandler
+
+# Initializes your app with your bot token and socket mode handler
+app = App(token=os.environ.get("SLACK_BOT_TOKEN"))
+
+# Start your app
+if __name__ == "__main__":
+    SocketModeHandler(app, os.environ["SLACK_APP_TOKEN"]).start()
+```
+
+Your tokens are enough to create your first Bolt app. Save your `app.py` file then on the command line run the following:
+
+```sh
+$ python3 app.py
+```
+
+Your app should let you know that it's up and running. 🎉
+
+---
+
+### Setting up events {#setting-up-events}
+Your app behaves similarly to people on your team — it can post messages, add emoji reactions, and listen and respond to events. 
+
+To listen for events happening in a Slack workspace (like when a message is posted or when a reaction is posted to a message) you'll use the [Events API to subscribe to event types](/apis/events-api/).
+
+For those just starting, we recommend using [Socket Mode](/apis/events-api/using-socket-mode). Socket Mode allows your app to use the Events API and interactive features without exposing a public HTTP Request URL. This can be helpful during development, or if you're receiving requests from behind a firewall.
+
+That being said, you're welcome to set up an app with a public HTTP Request URL. HTTP is more useful for apps being deployed to hosting environments to respond within a large corporate Slack workspaces/organization, or apps intended for distribution via the Slack Marketplace.
+
+We've provided instructions for both ways in this guide.
+
+import Tabs from '@theme/Tabs';
+import TabItem from '@theme/TabItem';
+
+<Tabs groupId="socket-or-http">
+<TabItem value="socket-mode" label="Socket Mode">
+
+1. Head to your app's configuration page (click on the app [from your app settings page](https://api.slack.com/apps)). Navigate to **Socket Mode** on the left side menu and toggle to enable.
+
+2. Go to **Basic Information** and scroll down under the App-Level Tokens section and click **Generate Token and Scopes** to generate an app-level token. Add the `connections:write` scope to this token and save the generated `xapp` token, we'll use that in just a moment.
+
+3. Finally, it's time to tell Slack what events we'd like to listen for. Under **Event Subscriptions**, toggle the switch labeled **Enable Events**.
+
+When an event occurs, Slack will send your app some information about the event, like the user that triggered it and the channel it occurred in. Your app will process the details and can respond accordingly.
+
+</TabItem>
+<TabItem value="http" label="HTTP">
+
+1. Go back to your app configuration page (click on the app [from your app management page](https://api.slack.com/apps)). Click **Event Subscriptions** on the left sidebar. Toggle the switch labeled **Enable Events**.
+
+2. Add your Request URL. Slack will send HTTP POST requests corresponding to events to this [Request URL](/apis/events-api/#subscribing) endpoint. Bolt uses the `/slack/events` path to listen to all incoming requests (whether shortcuts, events, or interactivity payloads). When configuring your Request URL within your app configuration, you'll append `/slack/events`, e.g. `https://<your-domain>/slack/events`. 💡 As long as your Bolt app is still running, your URL should become verified.
+
+:::tip[Using proxy services]
+
+For local development, you can use a proxy service like ngrok to create a public URL and tunnel requests to your development environment. Refer to [ngrok's getting started guide](https://ngrok.com/docs#getting-started-expose) on how to create this tunnel. And when you get to hosting your app, we've collected some of the most common hosting providers Slack developers use to host their apps [on our API site](/app-management/hosting-slack-apps). 
+
+:::
+
+</TabItem>
+</Tabs>
+
+Navigate to **Event Subscriptions** on the left sidebar and toggle to enable. Under **Subscribe to Bot Events**, you can add events for your bot to respond to. There are four events related to messages:
+- [`message.channels`](/reference/events/message.channels) listens for messages in public channels that your app is added to.
+- [`message.groups`](/reference/events/message.groups) listens for messages in 🔒 private channels that your app is added to.
+- [`message.im`](/reference/events/message.im) listens for messages in your app's DMs with users.
+- [`message.mpim`](/reference/events/message.mpim) listens for messages in multi-person DMs that your app is added to.
+
+If you want your bot to listen to messages from everywhere it is added to, choose all four message events. After you’ve selected the events you want your bot to listen to, click the green **Save Changes** button.
+
+---
+
+### Listening and responding to a message {#listening-and-responding-to-a-message}
+Your app is now ready for some logic. Let's start by using the `message()` method to attach a listener for messages.
+
+The following example listens and responds to all messages in channels/DMs where your app has been added that contain the word "hello":

+If you restart your app, so long as your bot user has been added to the channel or DM conversation, when you send any message that contains "hello", it will respond.
+
+This is a basic example, but it gives you a place to start customizing your app based on your own goals. Let's try something a little more interactive by sending a button rather than plain text.
+
+---
+
+### Sending and responding to actions {#sending-and-responding-to-actions}
+
+To use features like buttons, select menus, datepickers, modals, and shortcuts, you’ll need to enable interactivity. Head over to **Interactivity & Shortcuts** in your app configuration.
+
+<Tabs groupId="socket-or-http">
+<TabItem value="socket-mode" label="Socket Mode">
+
+With Socket Mode on, basic interactivity is enabled by default, so no further action is needed.
+
+</TabItem>
+<TabItem value="http" label="HTTP">
+
+Similar to events, you'll need to specify a URL for Slack to send the action (such as _user clicked a button_). Back on your app configuration page, click on **Interactivity & Shortcuts** on the left side. You'll see that there's another **Request URL** box.
+
+:::tip[By default, Bolt is configured to use the same endpoint for interactive components that it uses for events, so use the same request URL as above (for example, `https://8e8ec2d7.ngrok.io/slack/events`).] 
+
+Press the **Save Changes** button in the lower right hand corner, and that's it. Your app is set up to handle interactivity!
+
+:::
+
+</TabItem>
+</Tabs>
+
+When interactivity is enabled, interactions with shortcuts, modals, or interactive components (such as buttons, select menus, and datepickers) will be sent to your app as events.
+
+Now, let's go back to your app's code and add logic to handle those events:
+- First, we'll send a message that contains an interactive component (in this case a button).
+- Next, we'll listen for the action of a user clicking the button before responding.
+
+Below, the code from the last section is modified to send a message containing a button rather than just a string:
+
+<Tabs groupId="socket-or-http">
+<TabItem value="socket-mode" label="Socket Mode">
+
+```python
+import os
+from slack_bolt import App
+from slack_bolt.adapter.socket_mode import SocketModeHandler
+
+# Initializes your app with your bot token and socket mode handler
+app = App(
+    token=os.environ.get("SLACK_BOT_TOKEN"),
+    # signing_secret=os.environ.get("SLACK_SIGNING_SECRET") # not required for socket mode
+)
+
+# Listens to incoming messages that contain "hello"
+@app.message("hello")
+def message_hello(message, say):
+    # say() sends a message to the channel where the event was triggered
+    say(
+        blocks=[
+            {
+                "type": "section",
+                "text": {"type": "mrkdwn", "text": f"Hey there <@{message['user']}>!"},
+                "accessory": {
+                    "type": "button",
+                    "text": {"type": "plain_text", "text": "Click Me"},
+                    "action_id": "button_click"
+                }
+            }
+        ],
+        text=f"Hey there <@{message['user']}>!"
+    )
+
+# Start your app
+if __name__ == "__main__":
+    SocketModeHandler(app, os.environ["SLACK_APP_TOKEN"]).start()
+
+```
+
+</TabItem>
+<TabItem value="http" label="HTTP">
+
+```python
+import os
+from slack_bolt import App
+
+# Initializes your app with your bot token and signing secret
+app = App(
+    token=os.environ.get("SLACK_BOT_TOKEN"),
+    signing_secret=os.environ.get("SLACK_SIGNING_SECRET")
+)
+
+# Listens to incoming messages that contain "hello"
+@app.message("hello")
+def message_hello(message, say):
+    # say() sends a message to the channel where the event was triggered
+    say(
+        blocks=[
+            {
+                "type": "section",
+                "text": {"type": "mrkdwn", "text": f"Hey there <@{message['user']}>!"},
+                "accessory": {
+                    "type": "button",
+                    "text": {"type": "plain_text", "text": "Click Me"},
+                    "action_id": "button_click"
+                }
+            }
+        ],
+        text=f"Hey there <@{message['user']}>!"
+    )
+
+# Start your app
+if __name__ == "__main__":
+    app.start(port=int(os.environ.get("PORT", 3000)))
+```
+
+</TabItem>
+</Tabs>
+
+The value inside of `say()` is now an object that contains an array of `blocks`. Blocks are the building components of a Slack message and can range from text to images to datepickers. In this case, your app will respond with a section block that includes a button as an accessory. Since we're using `blocks`, the `text` is a fallback for notifications and accessibility.
+
+You'll notice in the button `accessory` object, there is an `action_id`. This will act as a unique identifier for the button so your app can specify which action it wants to respond to.
+
+:::tip[Using Block Kit Builder]
+
+The [Block Kit Builder](https://app.slack.com/block-kit-builder) is an simple way to prototype your interactive messages. The builder lets you (or anyone on your team) mock up messages and generates the corresponding JSON that you can paste directly in your app.
+
+:::
+
+Now, if you restart your app and say "hello" in a channel your app is in, you'll see a message with a button. But if you click the button, nothing happens (_yet!_).
+
+Let's add a handler to send a follow-up message when someone clicks the button:
+
+<Tabs groupId="socket-or-http">
+<TabItem value="socket-mode" label="Socket Mode">
+
+```python
+import os
+from slack_bolt import App
+from slack_bolt.adapter.socket_mode import SocketModeHandler
+
+# Initializes your app with your bot token and socket mode handler
+app = App(token=os.environ.get("SLACK_BOT_TOKEN"))
+
+# Listens to incoming messages that contain "hello"
+@app.message("hello")
+def message_hello(message, say):
+    # say() sends a message to the channel where the event was triggered
+    say(
+        blocks=[
+            {
+                "type": "section",
+                "text": {"type": "mrkdwn", "text": f"Hey there <@{message['user']}>!"},
+                "accessory": {
+                    "type": "button",

+        ],
+        text=f"Hey there <@{message['user']}>!"

+    say(f"<@{body['user']['id']}> clicked the button")
+
+# Start your app
+if __name__ == "__main__":
+    SocketModeHandler(app, os.environ["SLACK_APP_TOKEN"]).start()
+```
+
+</TabItem>
+<TabItem value="http" label="HTTP">
+
+```python
+import os
+from slack_bolt import App
+
+# Initializes your app with your bot token and signing secret

+                    "action_id": "button_click"
+                }
+            }
+        ],
+        text=f"Hey there <@{message['user']}>!"
+    )
+
+@app.action("button_click")

+    say(f"<@{body['user']['id']}> clicked the button")
+
+# Start your app
+if __name__ == "__main__":
+    app.start(port=int(os.environ.get("PORT", 3000)))
+```
+
+</TabItem>
+</Tabs>
+
+You can see that we used `app.action()` to listen for the `action_id` that we named `button_click`. If you restart your app and click the button, you'll see a new message from your app that says you clicked the button.
+
+---
+
+### Next steps {#next-steps}
+You just built your first [Bolt for Python app](https://github.com/slackapi/bolt-python/tree/main/examples/getting_started)! 🎉
+
+Now that you have a basic app up and running, you can start exploring how to make your Bolt app stand out. Here are some ideas about what to explore next:
+
+* Read through the concepts pages to learn about the different methods and features your Bolt app has access to.
+
+* Explore the different events your bot can listen to with the [`app.event()`](/tools/bolt-python/concepts/event-listening) method. View the full events reference docs [here](/reference/events).
+
+* Bolt allows you to [call Web API methods](/tools/bolt-python/concepts/web-api) with the client attached to your app. There are over 200 methods; view them [here](/reference/methods).
+
+* Learn more about the different token types in the [tokens guide](/authentication/tokens). Your app may need different tokens depending on the actions you want it to perform.

+# Experiments
+
+Bolt for Python includes experimental features still under active development. These features may be fleeting, may not be perfectly polished, and should be thought of as available for use "at your own risk." 
+
+Experimental features are categorized as `semver:patch` until the experimental status is removed.
+
+We love feedback from our community, so we encourage you to explore and interact with the [GitHub repo](https://github.com/slackapi/bolt-python). Contributions, bug reports, and any feedback are all helpful; let us nurture the Slack CLI together to help make building Slack apps more pleasant for everyone.
+
+## Available experiments
+* [Agent listener argument](#agent)
+
+## Agent listener argument {#agent}
+
+The `agent: BoltAgent` listener argument provides access to AI agent-related features.
+
+The `BoltAgent` and `AsyncBoltAgent` classes offer a `chat_stream()` method that comes pre-configured with event context defaults: `channel_id`, `thread_ts`, `team_id`, and `user_id` fields. 
+
+The listener argument is wired into the Bolt `kwargs` injection system, so listeners can declare it as a parameter or access it via the `context.agent` property.
+
+### Example
+
+```python
+from slack_bolt import BoltAgent
+
+@app.event("app_mention")
+def handle_mention(agent: BoltAgent):
+    stream = agent.chat_stream()
+    stream.append(markdown_text="Hello!")
+    stream.stop()
+```

+title: Quickstart guide with Bolt for Python
+---
+
+This quickstart guide aims to help you get a Slack app using Bolt for Python up and running as soon as possible!
+
+import Tabs from '@theme/Tabs';
+import TabItem from '@theme/TabItem';
+
+When complete, you'll have a local environment configured with a customized [app](https://github.com/slack-samples/bolt-python-getting-started-app) running to modify and make your own.
+
+:::tip[Reference for readers]
+
+In search of the complete guide to building an app from scratch? Check out the [building an app](/tools/bolt-python/building-an-app) guide.
+
+:::
+
+#### Prerequisites
+
+A few tools are needed for the following steps. We recommend using the [**Slack CLI**](/tools/slack-cli/) for the smoothest experience, but other options remain available. 
+
+You can also begin by installing git and downloading [Python 3.7 or later](https://www.python.org/downloads/), or the latest stable version of Python. Refer to [Python's setup and building guide](https://devguide.python.org/getting-started/setup-building/) for more details.
+
+Install the latest version of the Slack CLI to get started:
+
+- [Slack CLI for macOS & Linux](/tools/slack-cli/guides/installing-the-slack-cli-for-mac-and-linux)
+- [Slack CLI for Windows](/tools/slack-cli/guides/installing-the-slack-cli-for-windows)
+
+Then confirm a successful installation with the following command:
+
+```sh
+$ slack version
+```
+
+An authenticated login is also required if this hasn't been done before:
+
+```sh
+$ slack login
+```
+
+:::info[A place to belong]
+
+A workspace where development can happen is also needed.
+
+We recommend using [developer sandboxes](/tools/developer-sandboxes) to avoid disruptions where real work gets done.
+
+:::
+
+## Creating a project {#creating-a-project}
+
+With the toolchain configured, it's time to set up a new Bolt project. This contains the code that handles logic for your app.
+
+If you don’t already have a project, let’s create a new one!
+
+<Tabs groupId="cli-or-terminal">
+<TabItem value="cli" label="Slack CLI">
+
+A starter template can be used to start with project scaffolding:
+
+```sh
+$ slack create first-bolt-app --template slack-samples/bolt-python-getting-started-app
+$ cd first-bolt-app
+```
+
+After a project is created you'll have a `requirements.txt` file for app dependencies and a `.slack` directory for Slack CLI configuration.
+
+A few other files exist too, but we'll visit these later.
+
+</TabItem>
+<TabItem value="terminal" label="Terminal">
+
+A starter template can be cloned to start with project scaffolding:
+
+```sh
+$ git clone https://github.com/slack-samples/bolt-python-getting-started-app first-bolt-app
+$ cd first-bolt-app
+```
+
+Outlines of a project are taking shape, so we can move on to running the app!
+
+</TabItem>
+</Tabs>
+
+We recommend using a [Python virtual environment](https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/#creating-a-virtual-environment) to manage your project's dependencies. This is a great way to prevent conflicts with your system's Python packages. Let's create and activate a new virtual environment with [Python 3.7 or later](https://www.python.org/downloads/):
+
+```sh
+$ python3 -m venv .venv
+$ source .venv/bin/activate
+$ pip install -r requirements.txt
+```
+
+Confirm the virtual environment is active by checking that the path to `python3` is _inside_ your project ([a similar command is available on Windows](https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/#activating-a-virtual-environment)):
+
+```sh
+$ which python3
+# Output: /path/to/first-bolt-app/.venv/bin/python3
+```
+
+## Running the app {#running-the-app}
+
+Before you can start developing with Bolt, you will want a running Slack app.
+
+<Tabs groupId="cli-or-terminal">
+<TabItem value="cli" label="Slack CLI">
+
+The getting started app template contains a `manifest.json` file with details about an app that we will use to get started. Use the following command and select "Create a new app" to install the app to the team of choice:
+
+```sh
+$ slack run
+...
+⚡️ Bolt app is running!
+```
+
+With the app running, you can test it out with the following steps in Slack:
+
+1. Open a direct message with your app or invite the bot `@first-bolt-app (local)` to a public channel.
+2. Send "hello" to the current conversation and wait for a response.
+3. Click the attached button labelled "Click Me" to post another reply.
+
+After confirming the app responds, celebrate, then interrupt the process by pressing `CTRL+C` in the terminal to stop your app from running.
+
+</TabItem>
+<TabItem value="terminal" label="Browser">
+
+Navigate to your list of apps and [create a new Slack app](https://api.slack.com/apps/new) using the "from a manifest" option:
+
+1. Select the workspace to develop your app in.
+2. Copy and paste the `manifest.json` file contents to create your app.
+3. Confirm the app features and click "Create".
+
+You'll then land on your app's **Basic Information** page, which is an overview of your app and which contains important credentials:
+
+![Basic Information page](/img/bolt-python/basic-information-page.png "Basic Information page")
+
+To listen for events happening in Slack (such as a new posted message) without opening a port or exposing an endpoint, we will use [Socket Mode](/tools/bolt-python/concepts/socket-mode). This connection requires a specific app token:
+
+1. On the **Basic Information** page, scroll to the **App-Level Tokens** section and click **Generate Token and Scopes**.
+2. Name the token "Development" or something similar and add the `connections:write` scope, then click **Generate**.
+3. Save the generated `xapp` token as an environment variable within your project:
+
+```sh
+$ export SLACK_APP_TOKEN=<your-app-level-token>
+```
+
+The above command works on Linux and macOS but [similar commands are available on Windows](https://superuser.com/questions/212150/how-to-set-env-variable-in-windows-cmd-line/212153#212153).
+
+:::warning[Keep it secret. Keep it safe.]
+
+Treat your tokens like a password and [keep it safe](/security). Your app uses these to retrieve and send information to Slack.
+
+:::
+
+A bot token is also needed to interact with the Web API methods as your app's bot user. We can gather this as follows:
+
+1. Navigate to the **OAuth & Permissions** on the left sidebar and install your app to your workspace to generate a token.
+2. After authorizing the installation, you'll return to the **OAuth & Permissions** page and find a **Bot User OAuth Token**:
+
+![OAuth Tokens](/img/bolt-python/bot-token.png "Bot OAuth Token")
+
+3. Copy the bot token beginning with `xoxb` from the **OAuth & Permissions page** and then store it in a new environment variable:
+
+```sh
+$ export SLACK_BOT_TOKEN=xoxb-<your-bot-token>
+```
+
+After saving tokens for the app you created, it is time to run it:
+
+```sh
+$ python3 app.py
+...
+⚡️ Bolt app is running!
+```
+
+With the app running, you can test it out with the following steps in Slack:
+
+1. Open a direct message with your app or invite the bot `@BoltApp` to a public channel.
+2. Send "hello" to the current conversation and wait for a response.
+3. Click the attached button labelled "Click Me" to post another reply.
+
+After confirming the app responds, celebrate, then interrupt the process by pressing `CTRL+C` in the terminal to stop your app from running.
+
+</TabItem>
+</Tabs>
+
+## Updating the app
+
+At this point, you've successfully run the getting started Bolt for Python [app](https://github.com/slack-samples/bolt-python-getting-started-app)!
+
+The defaults included leave opportunities abound, so to personalize this app let's now edit the code to respond with a kind farewell.
+
+#### Responding to a farewell
+
+Chat is a common thing apps do and responding to various types of messages can make conversations more interesting.
+
+Using an editor of choice, open the `app.py` file and add the following import to the top of the file, and message listener after the "hello" handler:
+
+```python
+import random
+
+@app.message("goodbye")
+def message_goodbye(say):
+    responses = ["Adios", "Au revoir", "Farewell"]
+    parting = random.choice(responses)
+    say(f"{parting}!")
+```
+
+Once the file is updated, save the changes and then we'll make sure those changes are being used.
+
+<Tabs groupId="cli-or-terminal">
+<TabItem value="cli" label="Slack CLI">
+
+Run the following command and select the app created earlier to start, or restart, your app with the latest changes:
+
+```sh
+$ slack run
+...
+⚡️ Bolt app is running!
+```
+
+After finding the above output appears, open Slack to perform these steps:
+
+1. Return to the direct message or public channel with your bot.
+2. Send "goodbye" to the conversation.
+3. Receive a parting response from before and repeat "goodbye" to find another one.
+
+Your app can be stopped again by pressing `CTRL+C` in the terminal to end these chats.
+
+</TabItem>
+<TabItem value="terminal" label="Terminal">
+
+Run the following command to start, or restart, your app with the latest changes:
+
+```sh
+$ python3 app.py
+...
+⚡️ Bolt app is running!
+```
+
+After finding the above output appears, open Slack to perform these steps:
+
+1. Return to the direct message or public channel with your bot.
+2. Send "goodbye" to the conversation.
+3. Receive a parting response from before and repeat "goodbye" to find another one.
+
+Your app can be stopped again by pressing `CTRL+C` in the terminal to end these chats.
+
+</TabItem>
+</Tabs>
+
+#### Customizing app settings
+
+The created app will have some placeholder values and a small set of [scopes](/reference/scopes) to start, but we recommend exploring the customizations possible on app settings.
+
+<Tabs groupId="cli-or-terminal">
+<TabItem value="cli" label="Slack CLI">
+
+Open app settings for your app with the following command:
+
+```sh
+$ slack app settings
+```
+
+This will open the following page in a web browser:
+
+![Basic Information page](/img/bolt-python/basic-information-page.png "Basic Information page")
+
+</TabItem>
+<TabItem value="terminal" label="Browser">
+
+Browse to https://api.slack.com/apps and select your app "Getting Started Bolt App" from the list.
+
+This will open the following page:
+
+![Basic Information page](/img/bolt-python/basic-information-page.png "Basic Information page")
+
+</TabItem>
+</Tabs>
+
+On these pages you're free to make changes such as updating your app icon, configuring app features, and perhaps even distributing your app!
+
+## Next steps {#next-steps}
+
+You can now continue customizing your app with various features to make it right for whatever job's at hand. Here are some ideas about what to explore next:
+
+- Follow along with the steps that went into making this app on the [creating an app](/tools/bolt-python/creating-an-app) guide for an educational overview.
+- Check out the [Agent quickstart](/ai/agent-quickstart) to get up and running with an agent.
+- Browse our [curated catalog of samples](/samples) for more apps to use as a starting point for development.

+
+Steps from Apps are different than, and not interchangeable with, Slack automation workflows. We encourage those who are currently publishing steps from apps to consider the new [Slack automation features](/workflows/), such as [custom steps for Bolt](/workflows/workflow-steps).
+
+Please [read the Slack API changelog entry](/changelog/2023-08-workflow-steps-from-apps-step-back) for more information.
+
+:::
+
+Steps from apps allow your app to create and process steps that users can add using [Workflow Builder](/workflows/workflow-builder).
+
+Steps from apps are made up of three distinct user events:
+
+- Adding or editing the step in a Workflow
+- Saving or updating the step's configuration
+- The end user's execution of the step
+
+All three events must be handled for a step from app to function.
+
+Read more about steps from apps in the [API documentation](/workflows/workflow-steps).
+
+## Creating steps from apps
+
+To create a step from app, Bolt provides the `WorkflowStep` class.
+
+When instantiating a new `WorkflowStep`, pass in the step's `callback_id` and a configuration object.
+
+The configuration object contains three keys: `edit`, `save`, and `execute`. Each of these keys must be a single callback or a list of callbacks. All callbacks have access to a `step` object that contains information about the step from app event.
+
+After instantiating a `WorkflowStep`, you can pass it into `app.step()`. Behind the scenes, your app will listen and respond to the step’s events using the callbacks provided in the configuration object.
+
+Alternatively, steps from apps can also be created using the `WorkflowStepBuilder` class alongside a decorator pattern. For more information, including an example of this approach, [refer to the documentation](https://docs.slack.dev/tools/bolt-python/reference/workflows/step/step.html#slack_bolt.workflows.step.step.WorkflowStepBuilder).
+
+Refer to the module documents ([common](https://docs.slack.dev/tools/bolt-python/reference/kwargs_injection/args.html) / [step-specific](https://docs.slack.dev/tools/bolt-python/reference/workflows/step/utilities/index.html)) to learn the available arguments.
+
+```python
+import os
+from slack_bolt import App
+from slack_bolt.workflows.step import WorkflowStep
+
+# Initiate the Bolt app as you normally would
+app = App(
+    token=os.environ.get("SLACK_BOT_TOKEN"),
+    signing_secret=os.environ.get("SLACK_SIGNING_SECRET")
+)
+
+def edit(ack, step, configure):
+    pass
+
+def save(ack, view, update):
+    pass
+
+def execute(step, complete, fail):
+    pass
+
+# Create a new WorkflowStep instance
+ws = WorkflowStep(
+    callback_id="add_task",
+    edit=edit,
+    save=save,
+    execute=execute,
+)
+
+# Pass Step to set up listeners
+app.step(ws)
+```
+
+## Adding or editing steps from apps
+
+When a builder adds (or later edits) your step in their workflow, your app will receive a `workflow_step_edit` event. The `edit` callback in your `WorkflowStep` configuration will be run when this event is received.
+
+Whether a builder is adding or editing a step, you need to send them a step from app configuration modal. This modal is where step-specific settings are chosen, and it has more restrictions than typical modals—most notably, it cannot include `title`, `submit`, or `close` properties. By default, the configuration modal's `callback_id` will be the same as the step from app.
+
+Within the `edit` callback, the `configure()` utility can be used to easily open your step's configuration modal by passing in the view's blocks with the corresponding `blocks` argument. To disable saving the configuration before certain conditions are met, you can also pass in `submit_disabled` with a value of `True`.
+
+Refer to the module documents ([common](https://docs.slack.dev/tools/bolt-python/reference/kwargs_injection/args.html) / [step-specific](https://docs.slack.dev/tools/bolt-python/reference/workflows/step/utilities/index.html)) to learn the available arguments.
+
+```python
+def edit(ack, step, configure):
+    ack()
+
+    blocks = [
+        {
+            "type": "input",
+            "block_id": "task_name_input",
+            "element": {
+                "type": "plain_text_input",
+                "action_id": "name",
+                "placeholder": {"type": "plain_text", "text": "Add a task name"},
+            },
+            "label": {"type": "plain_text", "text": "Task name"},
+        },
+        {
+            "type": "input",
+            "block_id": "task_description_input",
+            "element": {
+                "type": "plain_text_input",
+                "action_id": "description",
+                "placeholder": {"type": "plain_text", "text": "Add a task description"},
+            },
+            "label": {"type": "plain_text", "text": "Task description"},
+        },
+    ]
+    configure(blocks=blocks)
+
+ws = WorkflowStep(
+    callback_id="add_task",
+    edit=edit,
+    save=save,
+    execute=execute,
+)
+app.step(ws)
+```
+
+## Saving step configurations
+
+After the configuration modal is opened, your app will listen for the `view_submission` event. The `save` callback in your `WorkflowStep` configuration will be run when this event is received.
+
+Within the `save` callback, the `update()` method can be used to save the builder's step configuration by passing in the following arguments:
+
+- `inputs` is a dictionary representing the data your app expects to receive from the user upon step execution.
+- `outputs` is a list of objects containing data that your app will provide upon the step's completion. Outputs can then be used in subsequent steps of the workflow.
+- `step_name` overrides the default Step name
+- `step_image_url` overrides the default Step image
+
+Refer to the module documents ([common](https://docs.slack.dev/tools/bolt-python/reference/kwargs_injection/args.html) / [step-specific](https://docs.slack.dev/tools/bolt-python/reference/workflows/step/utilities/index.html)) to learn the available arguments.
+
+```python
+def save(ack, view, update):
+    ack()
+
+    values = view["state"]["values"]
+    task_name = values["task_name_input"]["name"]
+    task_description = values["task_description_input"]["description"]
+                
+    inputs = {
+        "task_name": {"value": task_name["value"]},
+        "task_description": {"value": task_description["value"]}
+    }
+    outputs = [
+        {
+            "type": "text",
+            "name": "task_name",
+            "label": "Task name",
+        },
+        {
+            "type": "text",
+            "name": "task_description",
+            "label": "Task description",
+        }
+    ]
+    update(inputs=inputs, outputs=outputs)
+
+ws = WorkflowStep(
+    callback_id="add_task",
+    edit=edit,
+    save=save,
+    execute=execute,
+)
+app.step(ws)
+```
+
+## Executing steps from apps
+
+When your step from app is executed by an end user, your app will receive a `workflow_step_execute` event. The `execute` callback in your `WorkflowStep` configuration will be run when this event is received.
+
+Using the `inputs` from the `save` callback, this is where you can make third-party API calls, save information to a database, update the user's Home tab, or decide the outputs that will be available to subsequent steps from apps by mapping values to the `outputs` object.
+
+Within the `execute` callback, your app must either call `complete()` to indicate that the step's execution was successful, or `fail()` to indicate that the step's execution failed.
+
+Refer to the module documents ([common](https://docs.slack.dev/tools/bolt-python/reference/kwargs_injection/args.html) / [step-specific](https://docs.slack.dev/tools/bolt-python/reference/workflows/step/utilities/index.html)) to learn the available arguments.
+
+```python
+def execute(step, complete, fail):
+    inputs = step["inputs"]
+    # if everything was successful
+    outputs = {
+        "task_name": inputs["task_name"]["value"],
+        "task_description": inputs["task_description"]["value"],
+    }
+    complete(outputs=outputs)
+
+    # if something went wrong
+    error = {"message": "Just testing step failure!"}
+    fail(error=error)
+
+ws = WorkflowStep(
+    callback_id="add_task",
+    edit=edit,
+    save=save,
+    execute=execute,
+)
+app.step(ws)
+```

+# AI Chatbot
+
+In this tutorial, you'll learn how to bring the power of AI into your Slack workspace using a chatbot called Bolty that uses Anthropic or OpenAI.
+
+With Bolty, users can:
+
+- send direct messages to Bolty and get AI-powered responses in response,
+- use the `/ask-bolty` slash command to ask Bolty questions, and
+- receive channel summaries when joining new channels.
+
+Intrigued? First, grab your tools by following the three steps below.
+
+import QuickstartGuide from '@site/src/components/QuickstartGuide';
+
+<QuickstartGuide 
+  steps={[

+  ]}
+buttonText="View sample app"
+  buttonLink="https://github.com/slack-samples/bolt-python-ai-chatbot"
+  buttonIcon={true}
+/>
+
+<br/>
+
+## Prerequisites {#prereqs}
+
+You will also need the following:
+
+- a development workspace where you have permissions to install apps. If you don’t have a workspace you can join the [Developer Program](https://api.slack.com/developer-program) and provision a sandbox with access to all Slack features for free.
+- a development environment with [Python 3.7](https://www.python.org/downloads/) or later.
+- an Anthropic or OpenAI account with sufficient credits, and in which you have generated a secret key.
+
+### Obtaining and storing your environment variables {#environment-variables}
+
+Before you'll be able to successfully run the app, you'll need to first obtain and set some environment variables.
+
+#### Provider tokens {#provider-tokens}
+
+Models from different AI providers are available if the corresponding environment variable is added as shown in the sections below.
+
+<Tabs groupId="ai-providers">
+<TabItem value="anthropic" label="Anthropic">
+
+To interact with Anthropic models, navigate to your Anthropic account dashboard to [create an API key](https://console.anthropic.com/settings/keys), then export the key as follows:
+
+```bash
+export ANTHROPIC_API_KEY=<your-api-key>
+```
+
+</TabItem>
+<TabItem value="Google Cloud Vertex AI" label="Google Cloud Vertex AI">
+
+To use Google Cloud Vertex AI, [follow this quick start](https://cloud.google.com/vertex-ai/generative-ai/docs/start/quickstarts/quickstart-multimodal#expandable-1) to create a project for sending requests to the Gemini API, then gather [Application Default Credentials](https://cloud.google.com/docs/authentication/provide-credentials-adc) with the strategy to match your development environment.
+
+Once your project and credentials are configured, export environment variables to select from Gemini models:
+
+```bash
+export VERTEX_AI_PROJECT_ID=<your-project-id>
+export VERTEX_AI_LOCATION=<location-to-deploy-model>
+```
+
+The project location can be located under the **Region** on the [Vertex AI](https://console.cloud.google.com/vertex-ai) dashboard, as well as more details about available Gemini models.
+
+</TabItem>
+<TabItem value="OpenAI" label="OpenAI">
+
+Unlock the OpenAI models from your OpenAI account dashboard by clicking [create a new secret key](https://platform.openai.com/api-keys), then export the key like so:
+
+```bash
+export OPENAI_API_KEY=<your-api-key>
+```
+
+</TabItem>
+</Tabs>
+
+## Setting up and running your local project {#configure-project}
+
+
+Start your Python virtual environment:
+
+<Tabs groupId="os">
+<TabItem value="macos" label="macOS">
+
+```bash
+python3 -m venv .venv
+source .venv/bin/activate
+```
+
+</TabItem>
+<TabItem value="windows" label="Windows">
+
+```bash
+py -m venv .venv
+.venv\Scripts\activate
+```
+
+</TabItem>
+</Tabs>
+
+Install the required dependencies:
+
+```bash
+pip install -r requirements.txt
+```
+
+Run your app locally:
+
+```bash
+slack run
+```
+
+If your app is indeed up and running, you'll see a message that says "⚡️ Bolt app is running!"
+
+## Choosing your provider {#provider}
+
+Navigate to the Bolty **App Home** and select a provider from the drop-down menu. The options listed will be dependent on which secret keys you added when setting your environment variables.
+
+If you don't see Bolty listed under **Apps** in your workspace right away, never fear! You can mention **@Bolty** in a public channel to add the app, then navigate to your **App Home**.
+
+![Choose your AI provider](6.png)
+
+## Setting up your workflow {#workflow}
+
+Within your development workspace, open Workflow Builder by clicking on your workspace name and then **Tools > Workflow Builder**. Select **New Workflow** > **Build Workflow**.
+
+Click **Untitled Workflow** at the top to rename your workflow. For this tutorial, we'll call the workflow **Welcome to the channel**. Enter a description, such as _Summarizes channels for new members_, and click **Save**.
+
+![Setting up a new workflow](1.png)
+
+Select **Choose an event** under **Start the workflow...**, and then choose **When a person joins a channel**. Select the channel name from the drop-down menu and click **Save**.
+
+![Start the workflow](2.png)
+
+Under **Then, do these things**, click **Add steps** and complete the following:
+
+1. Select **Messages** > **Send a message to a person**.
+2. Under **Select a member**, choose **The user who joined the channel** from the drop-down menu.
+3. Under **Add a message**, enter a short message, such as _Hi! Welcome to `{}The channel that the user joined`. Would you like a summary of the recent conversation?_ Note that the _`{}The channel that the user joined`_ is a variable; you can insert it by selecting **{}Insert a variable** at the bottom of the message text box.
+4. Select the **Add Button** button, and name the button _Yes, give me a summary_. Click **Done**.
+
+![Send a message](3.png)
+
+We'll add two more steps under the **Then, do these things** section.
+
+First, scroll to the bottom of the list of steps and choose **Custom**, then choose **Bolty** and **Bolty Custom Function**. In the **Channel** drop-down menu, select **Channel that the user joined**. Click **Save**.
+
+![Bolty custom function](4.png)
+
+For the final step, complete the following:
+
+1. Choose **Messages** and then **Send a message to a person**. Under **Select a member**, choose **Person who clicked the button** from the drop-down menu.
+2. Under **Add a message**, click **Insert a variable** and choose **`{}Summary`** under the **Bolty Custom Function** section in the list that appears. Click **Save**.
+
+![Summary](5.png)
+
+When finished, click **Finish Up**, then click **Publish** to make the workflow available in your workspace.
+
+## Interacting with Bolty {#interact}
+
+### Summarizing recent conversations {#summarize}
+
+In order for Bolty to provide summaries of recent conversation in a channel, Bolty _must_ be a member of that channel.
+
+1. Invite Bolty to a channel that you are able to leave and rejoin (for example, not the **#general** channel or a private channel someone else created) by mentioning the app in the channel — i.e., tagging **@Bolty** in the channel and sending your message.
+2. Slackbot will prompt you to either invite Bolty to the channel, or do nothing. Click **Invite Them**. Now when new users join the channel, the workflow you just created will be kicked off.
+
+To test this, leave the channel you just invited Bolty to and rejoin it. This will kick off your workflow and you'll receive a direct message from **Welcome to the channel**. Click the **Yes, give me a summary** button, and Bolty will summarize the recent conversations in the channel you joined.
+
+![Channel summary](7.png)
+
+The central part of this functionality is shown in the following code snippet. Note the use of the [`user_context`](/tools/deno-slack-sdk/reference/slack-types#usercontext) object, a Slack type that represents the user who is interacting with our workflow, as well as the `history` of the channel that will be summarized, which includes the ten most recent messages.
+
+```python
+from ai.providers import get_provider_response
+from logging import Logger
+from slack_bolt import Complete, Fail, Ack
+from slack_sdk import WebClient
+from ..listener_utils.listener_constants import SUMMARIZE_CHANNEL_WORKFLOW
+from ..listener_utils.parse_conversation import parse_conversation
+
+"""
+Handles the event to summarize a Slack channel's conversation history.
+It retrieves the conversation history, parses it, generates a summary using an AI response,
+and completes the workflow with the summary or fails if an error occurs.
+"""
+
+def handle_summary_function_callback(
+    ack: Ack, inputs: dict, fail: Fail, logger: Logger, client: WebClient, complete: Complete
+):
+    ack()
+    try:
+        user_context = inputs["user_context"]
+        channel_id = inputs["channel_id"]
+        history = client.conversations_history(channel=channel_id, limit=10)["messages"]
+        conversation = parse_conversation(history)
+
+        summary = get_provider_response(user_context["id"], SUMMARIZE_CHANNEL_WORKFLOW, conversation)
+
+        complete({"user_context": user_context, "response": summary})
+    except Exception as e:
+        logger.exception(e)
+        fail(e)
+```
+
+### Asking Bolty a question {#ask-app}
+
+To ask Bolty a question, you can chat with Bolty in any channel the app is in. Use the `\ask-bolty` slash command to provide a prompt for Bolty to answer. Note that Bolty is currently not supported in threads.
+
+You can also navigate to **Bolty** in your **Apps** list and select the **Messages** tab to chat with Bolty directly.
+
+![Ask Bolty](8.png)
+
+## Next steps {#next-steps}
+
+Congratulations! You've successfully integrated the power of AI into your workspace. Check out these links to take the next steps in your Bolt for Python journey.

+2. Set up and run your local project
+3. Create a workflow with a custom step using Workflow Builder
+4. Create an issue in JIRA using your custom step
+
+## Prerequisites {#prereqs}
+
+Before getting started, you will need the following:
+
+* a development workspace where you have permissions to install apps. If you don’t have a workspace, go ahead and set that up now—you can [go here](https://slack.com/get-started#create) to create one, or you can join the [Developer Program](https://api.slack.com/developer-program) and provision a sandbox with access to all Slack features for free.
+* a development environment with [Python 3.7](https://www.python.org/downloads/) or later.
+
+**Skip to the code**
+If you'd rather skip the tutorial and just head straight to the code, you can use our [Bolt for Python JIRA functions sample](https://github.com/slack-samples/bolt-python-jira-functions) as a template.
+
+## Creating your app {#create-app}
+
+1. Navigate to the [app creation page](https://api.slack.com/apps/new) and select **From a manifest**.
+2. Select the workspace you want to install the application in, then click **Next**.
+3. Copy the contents of the [`manifest.json`](https://github.com/slack-samples/bolt-python-jira-functions/blob/main/manifest.json) file below into the text box that says **Paste your manifest code here** (within the **JSON** tab), then click **Next**:
+
+```js reference title="manifest.json"
+https://github.com/slack-samples/bolt-python-jira-functions/blob/main/manifest.json
+```
+
+4. Review the configuration and click **Create**.
+5. You're now in your app configuration's **Basic Information** page. Click **Install App**, then **Install to _your-workspace-name_**, then **Allow** on the screen that follows.
+
+### Obtaining and storing your environment variables {#environment-variables}
+
+Before you'll be able to successfully run the app, you'll need to obtain and set some environment variables.
+
+1. Once you have installed the app to your workspace, copy the **Bot User OAuth Token** from the **Install App** page. You will store this in your environment as `SLACK_BOT_TOKEN` (we'll get to that next).
+2. Navigate to **Basic Information** and in the **App-Level Tokens** section , click **Generate Token and Scopes**. Add the [`connections:write`](/reference/scopes/connections.write) scope, name the token, and click **Generate**. Copy this token. You will store this in your environment as `SLACK_APP_TOKEN`.
+3. Follow [these instructions](https://confluence.atlassian.com/adminjiraserver0909/configure-an-incoming-link-1251415519.html) to create an external app link and to generate its redirect URL (the base of which will be stored as your APP_BASE_URL variable below), client ID, and client secret.
+4. Run the following commands in your terminal to store your environment variables, client ID, and client secret.
+5. You'll also need to know your team ID (found by opening your Slack instance in a web browser and copying the value within the link that starts with the letter **T**) and your app ID (found under **Basic Information**).
+
+**For macOS**
+```bash
+export SLACK_BOT_TOKEN=<your-bot-token>
+export SLACK_APP_TOKEN=<your-app-token>
+export JIRA_CLIENT_ID=<client-id>
+export JIRA_CLIENT_SECRET=<client-secret>
+```
+
+**For Windows**
+```bash
+set SLACK_BOT_TOKEN=<your-bot-token>
+set SLACK_APP_TOKEN=<your-app-token>
+set JIRA_CLIENT_ID=<client-id>
+set JIRA_CLIENT_SECRET=<client-secret>
+```
+
+## Setting up and running your local project {#configure-project}
+
+Clone the starter template onto your machine by running the following command:
+
+```bash
+git clone https://github.com/slack-samples/bolt-python-jira-functions.git
+```
+
+Change into the new project directory:
+
+```bash
+cd bolt-python-jira-functions
+```
+
+Start your Python virtual environment:
+
+import Tabs from '@theme/Tabs';
+import TabItem from '@theme/TabItem';
+
+<Tabs groupId="os">
+<TabItem value="macos" label="For macOS">
+
+```bash
+python3 -m venv .venv
+source .venv/bin/activate
+```
+
+</TabItem>
+<TabItem value="windows" label="For Windows">
+
+```bash
+py -m venv .venv
+.venv\Scripts\activate
+```
+</TabItem>
+</Tabs>
+
+Install the required dependencies:
+
+```bash
+pip install -r requirements.txt
+```
+
+Rename the `.example.env` file to `.env` and replace the values for each of the variables listed in the file:
+
+```
+JIRA_BASE_URL=https://your-jira-instance.com
+SECRET_HEADER_KEY=Your-Header
+SECRET_HEADER_VALUE=abc123
+JIRA_CLIENT_ID=abc123
+JIRA_CLIENT_SECRET=abc123
+APP_BASE_URL=https://1234-123-123-12.ngrok-free.app
+APP_HOME_PAGE_URL=slack://app?team=YOUR_TEAM_ID&id=YOUR_APP_ID&tab=home
+```
+
+You could also store the values for your `SLACK_BOT_TOKEN` and `SLACK_APP_TOKEN` here.
+
+Start your local server:
+
+```bash
+python app.py
+```
+
+If your app is up and running, you'll see a message noting that the app is starting to receive messages from a new connection.
+
+## Setting up your workflow in Workflow Builder {#workflow}

+# Custom Steps for Workflow Builder (existing app)
+
+:::info[This feature requires a paid plan]
+If you don't have a paid workspace for development, you can join the [Developer Program](https://api.slack.com/developer-program) and provision a sandbox with access to all Slack features for free.
+:::
+
+If you followed along with our [create a custom step for Workflow Builder: new app](/tools/bolt-python/tutorial/custom-steps-workflow-builder-new) tutorial, you have seen how to add custom steps to a brand new app. But what if you have an app up and running currently to which you'd like to add custom steps? You've come to the right place!
+
+In this tutorial we will:
+- Start with an existing Bolt app
+- Add a custom **workflow step** in the [app settings](https://api.slack.com/apps)
+- Wire up the new step to a **function listener** in our project, using the [Bolt for Python](https://docs.slack.dev/tools/bolt-python/) framework
+- See the step as a custom workflow step in Workflow Builder
+
+## Prerequisites {#prereqs}
+
+The custom steps feature is compatible with Bolt version 1.20.0 and above. First, update your `package.json` file to reflect version 1.20.0 of Bolt, then run the following command in your terminal:
+
+```sh
+python3 -m venv .venv 
+source .venv/bin/activate 
+pip install -r requirements.txt
+```
+
+In order to add custom workflow steps to an app, the app also needs to be org-ready. To do this, navigate to your [app settings page](https://api.slack.com/apps) and select your Bolt app. 
+
+Navigate to **Org Level Apps** in the left nav and click **Opt-In**, then confirm **Yes, Opt-In**.
+
+![Make your app org-ready](org-ready.png)
+
+## Adding a new workflow step {#add-step}
+
+Before we can add the new workflow step, we first need to ensure the workflow step is listening for the `function_executed` event so that our app knows when the workflow step is executed.
+
+### Adding the `function_executed` event subscription {#event-subscription}
+
+Navigate to **App Manifest** in the left nav and add the `function_executed` event subscription, then click **Save Changes**:
+
+```json
+...
+    "settings": {
+        "event_subscriptions": {
+            "bot_events": [
+				...
+                "function_executed"
+            ]
+        },
+	}
+```
+
+### Adding the workflow step {#add-step}
+
+Navigate to **Workflow Steps** in the left nav and click **Add Step**. This is where we'll configure our step's inputs, outputs, name, and description.
+
+![Add step](add-step.png)
+
+For illustration purposes in this tutorial, we're going to write a custom step called Request Time Off. When the step is invoked, a message will be sent to the provided manager with an option to approve or deny the time-off request. When the manager takes an action (approves or denies the request), a message is posted with the decision and the manager who made the decision. The step will take two user IDs as inputs, representing the requesting user and their manager, and it will output both of those user IDs as well as the decision made.
+
+Add the pertinent details to the step:
+
+![Define step](define-step.png)
+
+Remember this `callback_id`. We will use this later when implementing a function listener. Then add the input and output parameters:
+
+![Add inputs](inputs.png)
+
+![Add outputs](outputs.png)
+
+Save your changes.
+
+### Viewing our updates in the App Manifest {#view-updates}
+
+Navigate to **App Manifest** and notice your new step reflected in the `functions` property! Exciting. It should look like this:
+
+```json
+"functions": {
+        "request_time_off": {
+            "title": "Request time off",
+            "description": "Submit a request to take time off",
+            "input_parameters": {
+                "manager_id": {
+                    "type": "slack#/types/user_id",
+                    "title": "Manager",
+                    "description": "Approving manager",
+                    "is_required": true,
+                    "hint": "Select a user in the workspace",
+                    "name": "manager_id"
+                },
+                "submitter_id": {
+                    "type": "slack#/types/user_id",
+                    "title": "Submitting user",
+                    "description": "User that submitted the request",
+                    "is_required": true,
+                    "name": "submitter_id"
+                }
+            },
+            "output_parameters": {
+                "manager_id": {
+                    "type": "slack#/types/user_id",
+                    "title": "Manager",
+                    "description": "Approving manager",
+                    "is_required": true,
+                    "name": "manager_id"
+                },
+                "request_decision": {
+                    "type": "boolean",
+                    "title": "Request decision",
+                    "description": "Decision to the request for time off",
+                    "is_required": true,
+                    "name": "request_decision"
+                },
+                "submitter_id": {
+                    "type": "slack#/types/user_id",
+                    "title": "Submitting user",
+                    "description": "User that submitted the request",
+                    "is_required": true,
+                    "name": "submitter_id"
+                }
+            }
+        }
+    }
+```
+
+Next, we'll define a function listener to handle what happens when the workflow step is used.
+
+## Adding function and action listeners {#adding-listeners}
+
+### Implementing the function listener {#function-listener}
+
+Direct your attention back to your app project in VSCode or your preferred code editor. Here we'll add logic that your app will execute when the custom step is executed. 
+
+Open your `app.py` file and add the following function listener code for the `request_time_off` step. 
+
+```py
+@app.function("request_time_off")
+def handle_request_time_off(inputs: dict, fail: Fail, logger: logging.Logger, say: Say):
+
+    submitter_id = inputs["submitter_id"]
+    manager_id = inputs["manager_id"]
+
+    try:
+        say(
+            channel=manager_id,
+            text=f"<@{submitter_id}> requested time off! What say you?",
+            blocks=[
+                {
+                    "type": 'section',
+                    "text": {
+                        "type": 'mrkdwn',
+                        "text": f"<@{submitter_id}> requested time off! What say you?",
+                    },
+                },
+                {
+                    'type': 'actions',
+                    'elements': [
+                        {
+                            'type': 'button',
+                            'text': {
+                                'type': 'plain_text',
+                                'text': 'Approve',
+                                'emoji': True,
+                            },
+                            'value': 'approve',
+                            'action_id': 'approve_button',
+                        },
+                        {
+                            'type': 'button',
+                            'text': {
+                                'type': 'plain_text',
+                                'text': 'Deny',
+                                'emoji': True,
+                            },
+                            'value': 'deny',
+                            'action_id': 'deny_button',
+                        },
+                    ],
+                },
+            ],
+        )
+    except Exception as e:
+        logger.exception(e)
+        fail(f"Failed to handle a function request (error: {e})")
+```
+
+#### Anatomy of a `.function()` listener {#function-listener-anatomy}
+
+The function decorator (`function()`) accepts an argument of type `str` and is the unique callback ID of the step. For our custom step, we’re using `request_time_off`. Every custom step you implement in an app needs to have a unique callback ID.
+
+The callback function is where we define the logic that will run when Slack tells the app that a user in the Slack client started a workflow that contains the `request_time_off` custom step.
+
+The callback function offers various utilities that can be used to take action when a function execution event is received. The ones we’ll be using here are:
+
+* `inputs` provides access to the workflow variables passed into the step when the workflow was started
+* `fail` indicates when the step invoked for the current workflow step has an error
+* `logger` provides a Python standard logger instance
+* `say` calls the `chat.Postmessage` API method
+
+### Implementing the action listener {#action-listener}
+
+This custom step also requires an action listener to respond to the action of a user clicking a button. 
+
+In that same `app.py` file, add the following action listener:
+
+```py
+@app.action(re.compile("(approve_button|deny_button)"))
+def manager_resp_handler(ack: Ack, action, body: dict, client: WebClient, complete: Complete, fail: Fail, logger: logging.Logger):
+
+    ack()
+
+    try:
+        inputs = body['function_data']['inputs']
+        manager_id = inputs['manager_id']
+        submitter_id = inputs['submitter_id']
+        request_decision = action['value']
+
+        client.chat_update(
+            channel=body['channel']['id'],
+            message=body['message'],
+            ts=body["message"]["ts"],
+            text=f'Request {"approved" if request_decision == 'approve' else "denied"}!'
+        )
+
+        complete({
+            'manager_id': manager_id,
+            'submitter_id': submitter_id,
+            'request_decision':  request_decision == 'approve'
+        })
+
+    except Exception as e:
+        logger.exception(e)
+        fail(f"Failed to handle a function request (error: {e})")
+```
+
+#### Anatomy of an `.action()` listener {#action-listener-anatomy}
+
+Similar to a function listener, the action listener registration method (`.action()`) takes two arguments:
+
+- The first argument is the unique callback ID of the action that your app will respond to. In our case, because we want to execute the same logic for both buttons, we’re using a little bit of RegEx magic to listen for two callback IDs at the same time — `approve_button` and `deny_button`.
+- The second argument is an asynchronous callback function, where we define the logic that will run when Slack tells our app that the manager has clicked or tapped the Approve button or the Deny button.
+
+Just like the function listener’s callback function, the action listener’s callback function offers various utilities that can be used to take action when an action event is received. The ones we’ll be using here are:
+- `client`, which provides access to Slack API methods
+- `action`, which provides the action’s event payload
+- `complete`, which is a utility method indicating to Slack that the step behind the workflow step that was just invoked has completed successfully
+- `fail`, which is a utility method for indicating that the step invoked for the current workflow step had an error
+
+Slack will send an action event payload to your app when one of the buttons is clicked or tapped. In the action listener, we’ll extract all the information we can use, and if all goes well, let Slack know the step was successful by invoking complete. We’ll also handle cases where something goes wrong and produces an error.
+
+Now that the custom step has been added to the app and we've defined step and action listeners for it, we're ready to see the step in action in Workflow Builder. Go ahead and run your app to pick up the changes.
+
+### Creating a workflow with the new step {#add-new-step}
+
+Turn your attention to the Slack client where your app is installed. 
+
+Open Workflow Builder by clicking on the workspace name, then **Tools**, then **Workflow Builder**.
+
+Click the button to create a **New Workflow**, then **Build Workflow**. Choose to start your workflow **from a link in Slack**.
+
+In the **Steps** pane to the right, search for your app name and locate the **Request time off** step we created.
+
+![Find step](find-step.png)
+
+Select the step and choose the desired inputs and click **Save**.
+
+![Step inputs](step-inputs.png)
+
+Next, click **Finish Up**, give your workflow a name and description, then click **Publish**. Copy the link for your workflow on the next screen, then click **Done**.
+
+### Running the workflow {#run-workflow}
+
+In any channel where your app is installed, paste the link you copied and send it as a message. The link will unfurl into a button to start the workflow. Click the button to start the workflow. If you set yourself up as the manager, you will then see a message from your app. Pressing either button will return a confirmation or denial of your time off request.
+
+![Message](app-message.png)
+
+## Next steps {#next-steps}
+
+Nice work! Now that you've added a workflow step to your Bolt app, a world of possibilities is open to you! Create and share workflow steps across your organization to optimize Slack users' time and make their working lives more productive.

+# Custom Steps for Workflow Builder (new app)
+
+:::info[This feature requires a paid plan]
+If you don't have a paid workspace for development, you can join the [Developer Program](https://api.slack.com/developer-program) and provision a sandbox with access to all Slack features for free.
+:::
+
+Adding a workflow step to your app and implementing a corresponding function listener is how you define a custom Workflow Builder step. In this tutorial, you'll use [Bolt for Python](/tools/bolt-python/) to add your workflow step, then wire it up in [Workflow Builder](https://slack.com/help/articles/360035692513-Guide-to-Workflow-Builder).
+
+When finished, you'll be ready to build scalable and innovative workflow steps for anyone using Workflow Builder in your workspace.
+
+## What are we building? {#what-are-we-building}
+
+In this tutorial, you'll be wiring up a sample app with a sample step and corresponding function listener to be used as a workflow step in Workflow Builder. Here's how it works:
+
+* When someone starts the workflow, Slack will notify your app that your custom step was invoked as part of a workflow.
+* Your app will send a message to the requestor, along with a button to complete the step.
+* When the user clicks or taps the button, Slack will let your app know, and your app will respond by changing the message.
+
+:::info[Skip to the code]
+If you'd rather skip the tutorial and just head straight to the code, create a new app and use our [Bolt Python custom step sample](https://github.com/slack-samples/bolt-python-custom-step-template) as a template. The sample custom step provided in the template will be a good place to start exploring!
+:::
+
+## Prerequisites {#prereqs}
+
+Before we begin, let's make sure you're set up for success. Ensure you have a development workspace where you have permission to install apps. We recommend setting up your own space used for exploration and testing in a [developer sandbox](https://api.slack.com/developer-program).
+
+## Cloning the sample project {#clone}
+
+For this tutorial, We'll use `boltstep` as the app name. For your app, be sure to use a unique name that will be easy for you to find: then, use that name wherever you see `boltstep` in this tutorial. The app will be named "Bolt Custom Step", as that is defined in the `manifest.json` file of the sample app code.
+
+Let's start by opening a terminal and cloning the starter template repository:
+
+```sh
+git clone https://github.com/slack-samples/bolt-python-custom-step-template boltstep
+```
+
+Once the terminal is finished cloning the template, change directories into your newly prepared app project:
+
+```sh
+cd boltstep
+```
+
+If you're using VSCode (highly recommended), you can enter `code .` from your project's directory and VSCode will open your new project.
+
+You can also open a terminal window from inside VSCode like this: `Ctrl` + `~`
+
+Once in VSCode, open the terminal. Let's install our package dependencies: run the following command(s) in the terminal inside VSCode:
+
+```sh
+npm install
+```
+
+We now have a Bolt app ready for development! Open the `manifest.json` file and copy its contents; you'll need this in the next step.
+
+## Creating your app from a manifest {#create-app}
+
+Open a browser and navigate to [your apps page](https://api.slack.com/apps). This is where we will create a new app with our previously copied manifest details. Click the **Create New App** button, then select **From an app manifest** when prompted to choose how you'd like to configure your app's settings.
+
+![Create app from manifest](manifest.png)
+
+Next, select a workspace where you have permissions to install apps, and click **Next**. Select the **JSON** tab and clear the existing contents. Paste the contents of the `manifest.json` file you previously copied.
+
+Click **Next** again. You will be shown a brief overview of the features your app includes. You'll see we are creating an app with a `chat:write` bot scope, an App Home and Bot User, as well as Socket Mode, Interactivity, an Event Subscription, and Org Deploy. We'll get into these details later. Click **Create**. 
+
+### App settings {#app-settings}
+
+All of your app's settings can be configured within these screens. By creating an app from an existing manifest, you will notice many settings have already been configured. Navigate to **Org Level Apps** and notice that we've already opted in. This is a requirement for adding workflow steps to an app. 
+
+Navigate to **Event Subscriptions** and expand **Subscribe to bot events** to see that we have subscribed to the `function_executed` event. This is also a requirement for adding workflow steps to our app, as it lets our app know when a step has been triggered, allowing our app to respond to it. 
+
+Another configuration setting to note is **Socket Mode**. We have turned this on for our local development, but socket mode is not intended for use in a production environment. When you are satisfied with your app and ready to deploy it to a production environment, you should switch to using public HTTP request URLs. Read more about getting started with HTTP in [Bolt for Python here](/tools/bolt-python/getting-started).
+
+Clicking on **Workflow Steps** in the left nav will show you that one workflow step has been added! This reflects the `function` defined in our manifest: functions are workflow steps. We will get to this step's implementation later.
+
+![Workflow step](workflow-step.png)
+
+### Tokens {#tokens}
+
+In order to connect our app here with the logic of our sample code set up locally, we need to obtain two tokens, a bot token and an app token. 
+
+* **Bot tokens** are associated with bot users, and are only granted once in a workspace where someone installs the app. The bot token your app uses will be the same no matter which user performed the installation. Bot tokens are the token type that most apps use.
+* **App-level** tokens represent your app across organizations, including installations by all individual users on all workspaces in a given organization and are commonly used for creating websocket connections to your app.
+
+To generate an app token, navigate to **Basic Information** and scroll down to **App-Level Token**. 
+
+![App token](app-token.png)
+
+Click **Generate Token and Scopes**, then **Add Scope** and choose `connections:write`. Choose a name for your token and click **Generate**. Copy that value, save it somewhere accessible, and click **Done** to close out of the modal.
+
+Next up is the bot token. We can only get this token by installing the app into the workspace. Navigate to **Install App** and click the button to install, choosing **Allow** at the next screen. 
+
+![Install app](install.png)
+
+You will then have a bot token. Again, copy that value and save it somewhere accessible.
+
+![Bot token](bot-token.png)
+
+💡 Treat your tokens like passwords and keep them safe. Your app uses them to post and retrieve information from Slack workspaces. Minimally, do NOT commit them to version control.
+
+## Starting your local development server {#local}
+
+While building your app, you can see your changes appear in your workspace in real-time with `npm start`. Soon we'll start our local development server and see what our sample code is all about! But first, we need to store those tokens we gathered as environment variables. 
+
+Navigate back to VSCode. Rename the `.env.sample` file to `.env`. Open this file and update `SLACK_APP_TOKEN` and `SLACK_BOT_TOKEN` with the values you previously saved. It will look like this, with your actual token values where you see `<your_app_token>` and `<your_bot_token>`:
+
+```sh
+SLACK_APP_TOKEN=<your_app_token>
+SLACK_BOT_TOKEN=<your_bot_token>
+```
+
+Now save the file and try starting your app:
+
+```sh
+npm start
+```
+
+You'll know the local development server is up and running successfully when it emits a bunch of `[DEBUG]` statements to your terminal, the last one containing `connected:ready`.
+
+With your development server running, continue to the next step.
+
+:::info[If you need to stop running the local development server, press `<CTRL>` + `c` to end the process.]
+:::
+
+## Wiring up the sample step in Workflow Builder {#wfb}
+
+The starter project you cloned contains a sample custom step lovingly titled “Sample step". Let’s see how a custom step defined in Bolt appears in Workflow Builder.
+
+In the Slack Client of your development workspace, open Workflow Builder by clicking on the workspace name, **Tools**, then **Workflow Builder**. Create a new workflow, then select **Build Workflow**:
+
+![Creating a new workflow](wfb-1.png)
+
+Select **Choose an event** under **Start the workflow...**, then **From a link in Slack** to configure this workflow to start when someone clicks its shortcut link:
+
+![Starting a new workflow from a shortcut link](wfb-2.png)
+
+Click the **Continue** button to confirm that this is workflow should start with a shortcut link:
+
+![Confirming a new shortcut workflow setup](wfb-3.png)
+
+Find the sample step provided in the template by either searching for the name of your app (e.g., `Bolt Custom Step`) or the name of your step (e.g. `Sample step`) in the Steps search bar.
+
+If you search by app name, any custom step that your app has defined will be listed.
+
+Add the “Sample step" in the search results to the workflow:
+
+![Adding the sample step to the workflow](wfb-4.png)
+
+As soon as you add the “Sample step" to the workflow, a modal will appear to configure the step's input&mdash;in this case, a user variable:
+
+![Configuring the sample step's inputs](wfb-5.png)
+
+Configure the user input to be “Person who used this workflow”, then click the **Save** button:
+
+![Saving the sample step after configuring the user input](wfb-6.png)
+
+Click the **Finish Up** button, then provide a name and description for your workflow.
+
+Finally, click the **Publish** button:
+
+![Publishing a workflow](wfb-7.png)
+
+Copy the shortcut link, then exit Workflow Builder and paste the link to a message in any channel you’re in:
+
+![Copying a workflow link](wfb-8.png)
+
+After you send a message containing the shortcut link, the link will unfurl and you’ll see a **Start Workflow** button.
+
+Click the **Start Workflow** button:
+
+![Starting your new workflow](wfb-9.png)
+
+You should see a new direct message from your app:
+
+![A new direct message from your app](wfb-10.png)
+
+The message from your app asks you to click the **Complete step** button:
+
+![A new direct message from your app](wfb-11.png)
+
+Once you click the button, the direct message to you will be updated to let you know that the step interaction was successfully completed:
+
+![Sample step finished successfully](wfb-12.png)
+
+Now that we’ve gotten a feel for how we will use the custom step, let’s learn more about how function listeners work.
+
+## Discovering listeners {#listeners}
+
+Now that we’ve seen how custom steps are used in Workflow Builder, let’s understand how the function listener code works to respond to an event when the step is triggered.
+
+We’ll first review the step definition in the `manifest.json`, then we’ll look at the two listener functions in our app code: one to let us know when the step starts, and one to let us know when someone clicks or taps one of the buttons we sent over.
+
+### Defining the custom step {#define-custom-step}
+
+Opening the `manifest.json` file included in the sample app shows a `functions` property that includes a definition for our `sample_step`:
+
+```json
+// manifest.json
+...
+    "functions": {
+        "sample_step": {
+            "title": "Sample step",
+            "description": "Runs sample step",
+            "input_parameters": {
+                "user_id": {
+                    "type": "slack#/types/user_id",
+                    "title": "User",
+                    "description": "Message recipient",
+                    "is_required": true,
+                    "hint": "Select a user in the workspace",
+                    "name": "user_id"
+                }
+            },
+            "output_parameters": {
+                "user_id": {
+                    "type": "slack#/types/user_id",
+                    "title": "User",
+                    "description": "User that completed the step",
+                    "is_required": true,
+                    "name": "user_id"
+                }
+            }
+        }
+    }
+```
+
+From the step definition, we can see an input parameter and an output parameter defined.
+
+### Inputs and outputs {#inputs-outputs}
+
+The custom step will take the following input: Message recipient (as a Slack User ID).
+
+The custom step will produce the following output: The user that completed the step.
+
+* When the step is invoked, a message will be sent to the user who invoked the workflow with a button to complete the step.
+* When the button is clicked, a message is posted indicating the step's completion.
+
+### Implementing the function listener {#function-listener}
+
+The first thing we’ll do when adding a custom workflow step to our Bolt app is register a new **function listener**. In Bolt, a function listener allows developers to execute custom code in response to specific Slack events or actions by registering a method that handles predefined requests or commands. We register a function listener via the `function` method provided by our app instance.
+
+1. Open your project’s `app.py` file in your code editor.
+2. Between the initialization code for the app instance and the `sample_step` registration, you'll see a listener defined for our custom step:
+
+```py
+# app.py
+...
+@app.function("sample_step")
+def handle_sample_step_event(inputs: dict, say: Say, fail: Fail, logger: logging.Logger):
+    user_id = inputs["user_id"]
+
+    try:
+        say(
+            channel=user_id,  # sending a DM to this user
+            text="Click the button to signal the step has completed",
+            blocks=[
+                {
+                    "type": "section",
+                    "text": {"type": "mrkdwn", "text": "Click the button to signal the step has completed"},
+                    "accessory": {
+                        "type": "button",
+                        "text": {"type": "plain_text", "text": "Complete step"},
+                        "action_id": "sample_click",
+                    },
+                }
+            ],
+        )
+    except Exception as e:
+        logger.exception(e)
+        fail(f"Failed to handle a step request (error: {e})")
+
+
+```
+
+#### Anatomy of a `.function()` listener {#function-listener-anatomy}
+
+The function decorator (`function()`) accepts an argument of type `str` and is the unique callback ID of the step. For our custom step, we’re using `sample_step`. Every custom step you implement in an app needs to have a unique callback ID.
+
+The callback function is where we define the logic that will run when Slack tells the app that a user in the Slack client started a workflow that contains the `sample_step` custom step.
+
+The callback function offers various utilities that can be used to take action when a step execution event is received. The ones we’ll be using here are:
+
+* `inputs` provides access to the workflow variables passed into the step when the workflow was started
+* `fail` indicates when the step invoked for the current workflow step has an error
+* `logger` provides a Python standard logger instance
+* `say` calls the `chat.Postmessage` API method
+
+#### Understanding the function listener's callback logic {#function-listener-callback-logic}
+
+When our step is executed, we want a message to be sent to the invoking user. That message should include a button that prompts the user to complete the step. 
+
+When Slack tells your Bolt app that the `sample_step` step was invoked, this step uses `chat.postMessage` to send a message to the `user_id` channel (which means this will be sent as a DM to the Slack user whose ID == `user_id`) with some text and blocks. The Block Kit element being sent as part of the message is a button, labeled 'Complete step' (which sends the `sample_click` action ID).
+
+Once the message is sent, your Bolt app will wait until the user has clicked the button. As soon as they click or tap the button, Slack will send back the action ID associated with the button to your Bolt app.
+
+In order for your Bolt app to listen for these actions, we’ll now define an action listener.
+
+### Implementing the action listener {#action-listener}
+
+The message we send to the user will include the button prompting them to complete the step. 
+
+To listen for and respond to this button click, you'll see an `.action()` listener to `app.py`, right after the function listener definition:
+
+```py
+# app.py
+...
+@app.action("sample_click")
+def handle_sample_click(
+    ack: Ack, body: dict, context: BoltContext, client: WebClient, complete: Complete, fail: Fail, logger: logging.Logger
+):
+    ack()
+
+    try:
+        # Since the button no longer works, we should remove it
+        client.chat_update(
+            channel=context.channel_id,
+            ts=body["message"]["ts"],
+            text="Congrats! You clicked the button",
+        )
+
+        # Signal that the step completed successfully
+        complete({"user_id": context.actor_user_id})
+    except Exception as e:
+        logger.exception(e)
+        fail(f"Failed to handle a step request (error: {e})")
+
+```
+
+#### Anatomy of an `.action()` listener {#action-listener-anatomy}
+
+Similar to a function listener, the action listener registration method (`.action()`) takes two arguments:
+
+* The first argument is the unique callback ID of the action that your app will respond to. 
+* The second argument is an asynchronous callback function, where we define the logic that will run when Slack tells our app that the user has clicked or tapped the button.
+
+Just like the function listener’s callback function, the action listener’s callback function offers various utilities that can be used to take action when an action event is received. The ones we’ll be using here are:
+
+* `client`, which provides access to Slack API methods
+* `action`, which provides the action’s event payload
+* `complete`, which is a utility method indicating to Slack that the step behind the workflow step that was just invoked has completed successfully
+* `fail`, which is a utility method for indicating that the step invoked for the current workflow step had an error
+
+#### Understanding the action listener's callback logic {#action-listener-callback-logic}
+
+Recall that we sent over a message with the button back in the function listener.
+
+When the button is pressed, we want to complete the step, update the message, and define `outputs` that can be used for subsequent steps in Workflow Builder.
+
+Slack will send an action event payload to your app when the button is clicked or tapped. In the action listener, we extract all the information we can use, and if all goes well, let Slack know the step was successful by invoking `complete`. We also handle cases where something goes wrong and produces an error.
+
+## Next steps {#next-steps}
+
+That's it — we hope you learned a lot!
+
+In this tutorial, we added custom steps via the manifest, but if you'd like to see how to add custom steps in the [app settings](https://api.slack.com/apps) to an existing app, follow along with the [Create a custom step for Workflow Builder: existing Bolt app](/tools/bolt-python/tutorial/custom-steps-workflow-builder-existing) tutorial.
+
+If you're interested in exploring how to create custom steps to use in Workflow Builder as steps with our Deno Slack SDK, too, that tutorial can be found [here](/tools/deno-slack-sdk/tutorials/workflow-builder-custom-step/).

+title: Custom Steps
+---
+
+:::info[This feature requires a paid plan]
+If you don't have a paid workspace for development, you can join the [Developer Program](https://api.slack.com/developer-program) and provision a sandbox with access to all Slack features for free.
+:::
+
+
+With custom steps for Bolt apps, your app can create and process workflow steps that users later add in Workflow Builder. This guide goes through how to build a custom step for your app using the [app settings](https://api.slack.com/apps). 
+
+If you're looking to build a custom step using the Deno Slack SDK, check out our guide on [creating a custom step for Workflow Builder with the Deno Slack SDK](/tools/deno-slack-sdk/tutorials/workflow-builder-custom-step/).
+
+You can also take a look at the template for the [Bolt for Python custom workflow step](https://github.com/slack-samples/bolt-python-custom-step-template) on GitHub.
+
+There are two components of a custom step: the step definition in the app manifest, and a listener to handle the `function_executed` event in your project code. 
+
+## Opt in to org-ready apps {#org-ready-apps}
+
+Before we create the step definition, we first need to opt in to organization-ready apps. The app must opt-in to org-ready apps to be able to add the custom step to its manifest. This can be done in one of two ways: 
+
+- Set the manifest `settings.org_deploy_enabled` property to `true`.
+- Alternatively, navigate to your [apps](https://api.slack.com/apps), select your app, then under the **Features** section in the navigation, select **Org Level Apps** and then **Opt-In**.
+
+Whichever method you use, the following will be reflected in the app manifest as such:
+
+```json
+    "settings": {
+        "org_deploy_enabled": true,
+        ...
+    }
+```
+
+Next, the app must be installed at the organization level. While it is possible to install the app at a workspace level, doing so means that the custom steps will not appear in Workflow Builder. To remedy this, install the app at the organization level.
+
+If you are a developer who is not an admin of their organization, you will need to request an Org Admin to perform this installation at the organization level. To do this:
+
+- Navigate to your [apps](https://api.slack.com/apps) page and select the app you'd like to install.
+- Under **Settings**, select **Collaborators**.
+- Add an Org Admin as a collaborator.
+
+The Org Admin can then install your app directly at the org level from the [app settings](https://api.slack.com/apps) page.
+
+## Defining the custom step {#define-step}
+
+A workflow step's definition contains information about the step, including its `input_parameters`, `output_parameters`, as well as display information. 
+
+Each step is defined in the `functions` object of the manifest. Each entry in the `functions` object is a key-value pair representing each step. The key is the step's `callback_id`, which is any string you wish to use to identify the step (max 100 characters), and the value contains the details listed in the table below for each separate custom step. We recommend using the step's name, like `sample_step` in the code example below for the step's `callback_id`.
+
+Field | Type | Description | Required? 
+---- | ----- | ------------|----------
+`title` | String | A string to identify the step. Max 255 characters. | Yes 
+`description` | String | A succinct summary of what your step does. | No 
+`input_parameters` | Object | An object which describes one or more [input parameters](#inputs-outputs) that will be available to your step. Each top-level property of this object defines the name of one input parameter available to your step.| No 
+`output_parameters` | Object | An object which describes one or more [output parameters](#inputs-outputs) that will be returned by your step. Each top-level property of this object defines the name of one output parameter your step makes available. | No 
+
+Once you are in your [app settings](https://api.slack.com/apps), navigate to **Workflow Steps** in the left nav. Click **Add Step** and fill out your step details, including callback ID, name, description, input parameters, and output parameters. 
+
+### Defining input and output parameters {#inputs-outputs}
+
+Step inputs and outputs (`input_parameters` and `output_parameters`) define what information goes into a step before it runs and what comes out of a step after it completes, respectively.
+
+Both inputs and outputs adhere to the same schema and consist of a unique identifier and an object that describes the input or output.
+
+Each input or output that belongs to `input_parameters` or `output_parameters` must have a unique key.
+
+Field | Type | Description 
+------|------|-------------
+`type` | String | Defines the data type and can fall into one of two categories: primitives or Slack-specific. 
+`title` | String | The label that appears in Workflow Builder when a user sets up this step in their workflow.
+`description` | String | The description that accompanies the input when a user sets up this step in their workflow.
+`dynamic_options` | Object | For custom steps dynamic options in Workflow Builder, define this property and point to a custom step designed to return the set of dynamic elements once the step is added to a workflow within Workflow Builder. Dynamic options in Workflow Builder can be rendered in one of two ways: as a drop-down menu (single-select or multi-select), or as a set of fields. Refer to custom steps dynamic options for Workflow Builder using [Bolt for JavaScript](/tools/bolt-js/concepts/custom-steps-dynamic-options/) or [Bolt for Python](https://docs.slack.dev/tools/bolt-python/concepts/custom-steps-dynamic-options/) for more details.
+`is_required` | Boolean | Indicates whether or not the input is required by the step in order to run. If it’s required and not provided, the user will not be able to save the configuration nor use the step in their workflow. This property is available only in v1 of the manifest. We recommend v2, using the `required` array as noted in the example above.
+`hint` | String | Helper text that appears below the input when a user sets up this step in their workflow.
+
+In addition, the `dynamic_options` field has two required properties:
+
+Property | Type | Description 
+------|------|-------------
+`function` | String | A reference to the custom step that should be used as a dynamic option.
+`inputs` | Object | Maps the inputs from the custom step consuming the dynamic option to the inputs required by the step used as a dynamic option.
+
+For example:
+
+```
+"inputs": {
+  "category": {
+    "value": "{{input_parameters.category}}"
+  }
+}
+```
+
+Once you've added your step details, save your changes, then navigate to **App Manifest**. Notice your new step configuration reflected in the `function` property!
+
+#### Sample manifest {#sample-manifest}
+
+Here is a sample app manifest laying out a step definition. This definition tells Slack that the step in our workspace with the callback ID of `sample_step` belongs to our app, and that when it runs, we want to receive information about its execution event.
+
+```json
+"functions": {
+    "sample_step": {
+        "title": "Sample step",
+        "description": "Runs sample step",
+        "input_parameters": {
+          "properties": {
+            "user_id": {
+                "type": "slack#/types/user_id",
+                "title": "User",
+                "description": "Message recipient",
+                "hint": "Select a user in the workspace",
+                "name": "user_id"
+            }
+          },
+          "required": {
+            "user_id"
+          }
+        },
+        "output_parameters": {
+          "properties": {
+            "user_id": {
+                "type": "slack#/types/user_id",
+                "title": "User",
+                "description": "User that received the message",
+                "name": "user_id"
+            }
+          },
+          "required": {
+            "user_id"
+          }
+        },
+    }
+}
+```
+
+### Adding steps for existing apps {#existing-apps}
+
+If you are adding custom steps to an existing app directly to the app manifest, you will also need to add the `function_runtime` property to the app manifest. Do this in the `settings` section as such:
+
+```json
+"settings": {
+	...
+	"function_runtime": "remote"
+}
+```
+
+If you are adding custom steps in the **Workflow Steps** section of the [App Config](https://api.slack.com/apps) as shown above, then this will be added automatically.
+
+## Listening to function executions {#listener}
+
+When your custom step is executed in a workflow, your app will receive a `function_executed` event. The callback provided to the `function()` method will be run when this event is received.
+
+The callback is where you can access `inputs`, make third-party API calls, save information to a database, update the user’s Home tab, or set the output values that will be available to subsequent workflow steps by mapping values to the `outputs` object.
+
+Your app must call `complete()` to indicate that the step’s execution was successful, or `fail()` to signal that the step failed to complete.
+
+Notice in the example code here that the name of the step, `sample_step`, is the same as it is listed in the manifest above. This is required.
+
+```py
+@app.function("sample_step")
+def handle_sample_step_event(inputs: dict, fail: Fail, complete: Complete,logger: logging.Logger):
+    user_id = inputs["user_id"]
+    try:
+        client.chat_postMessage( 
+            channel=user_id, 
+            text=f"Greetings <@{user_id}>!" 
+        )
+        complete({"user_id": user_id})
+    except Exception as e:
+        logger.exception(e)
+        fail(f"Failed to complete the step: {e}")
+
+```
+
+Here's another example. Note in this snippet, the name of the step, `create_issue`, must be listed the same as it is listed in the manifest file.
+
+```py
+@app.function("create_issue")
+def create_issue_callback(ack: Ack, inputs: dict, fail: Fail, complete: Complete, logger: logging.Logger):
+    ack()
+    JIRA_BASE_URL = os.getenv("JIRA_BASE_URL")
+
+    headers = {
+        "Authorization": f'Bearer {os.getenv("JIRA_SERVICE_TOKEN")}',
+        "Accept": "application/json",
+        "Content-Type": "application/json",
+    }
+
+    try:
+        project: str = inputs["project"]
+        issue_type: str = inputs["issuetype"]
+
+        url = f"{JIRA_BASE_URL}/rest/api/latest/issue"
+
+        payload = json.dumps(
+            {
+                "fields": {
+                    "description": inputs["description"],
+                    "issuetype": {"id" if issue_type.isdigit() else "name": issue_type},
+                    "project": {"id" if project.isdigit() else "key": project},
+                    "summary": inputs["summary"],
+                },
+            }
+        )
+
+        response = requests.post(url, data=payload, headers=headers)
+
+        response.raise_for_status()
+        json_data = json.loads(response.text)
+        complete(outputs={
+            "issue_id": json_data["id"],
+            "issue_key": json_data["key"],
+            "issue_url": f'https://{JIRA_BASE_URL}/browse/{json_data["key"]}'
+        })
+    except Exception as e:
+        logger.exception(e)
+        fail(f"Failed to handle a step request (error: {e})")
+
+```
+
+### Anatomy of a function listener {#anatomy}
+
+The first argument (in our case above, `sample_step`) is the unique callback ID of the step. After receiving an event from Slack, this identifier is how your app knows which custom step handler to invoke. This `callback_id` also corresponds to the step definition provided in your manifest file. 
+
+The second argument is the callback function, or the logic that will run when your app receives notice from Slack that `sample_step` was run by a user&mdash;in the Slack client&mdash;as part of a workflow.
+
+Field | Description
+------|------------
+`client` | A `WebClient` instance used to make things happen in Slack. From sending messages to opening modals, `client` makes it all happen. For a full list of available methods, refer to the [Web API methods](/reference/methods). Read more about the `WebClient` for Bolt Python [here](https://docs.slack.dev/tools/bolt-python/concepts/web-api/).
+`complete` | A utility method that invokes `functions.completeSuccess`. This method indicates to Slack that a step has completed successfully without issue. When called, `complete` requires you include an `outputs` object that matches your step definition in [`output_parameters`](#inputs-outputs).
+`fail` | A utility method that invokes `functions.completeError`. True to its name, this method signals to Slack that a step has failed to complete. The `fail` method requires an argument of `error` to be sent along with it, which is used to help users understand what went wrong.
+`inputs` | An alias for the `input_parameters` that were provided to the step upon execution.
+
+## Responding to interactivity {#interactivity}
+
+Interactive elements provided to the user from within the `function()` method’s callback are associated with that unique `function_executed` event. This association allows for the completion of steps at a later time, like once the user has clicked a button.
+
+Incoming actions that are associated with a step have the same `inputs`, `complete`, and `fail` utilities as offered by the `function()` method.
+
+```py
+# If associated with a step, step-specific utilities are made available 
+@app.action("sample_click")
+def handle_sample_click(context: BoltContext, complete: Complete, fail: Fail, logger: logging.Logger):
+    try:
+        # Signal the step has completed once the button is clicked
+        complete({"user_id": context.actor_user_id})
+    except Exception as e:
+        logger.exception(e)
+        fail(f"Failed to handle a step request (error: {e})")
+
+```
+
+## Deploying a custom step {#deploy}
+
+When you're ready to deploy your steps for wider use, you'll need to decide *where* to deploy, since Bolt apps are not hosted on the Slack infrastructure.
+
+### Control step access {#access}
+
+You can choose who has access to your custom steps. To define this, refer to the [custom function access](/tools/deno-slack-sdk/guides/controlling-access-to-custom-functions) page.
+
+### Distribution {#distribution}
+
+Distribution works differently for Slack apps that contain custom steps when the app is within a standalone (non-Enterprise Grid) workspace versus within an Enterprise Grid organization.
+
+* **Within a standalone workspace**: Slack apps that contain custom steps can be installed on the same workspace and used within that workspace. We do not support distribution to other standalone workspaces (also known as public distribution). 
+* **Within an organization**: Slack apps that contain custom steps should be org-ready (enabled for private distribution) and installed on the organization level. They must also be granted access to at least one workspace in the organization for the steps to appear in Workflow Builder.
+
+Apps containing custom steps cannot be distributed publicly or submitted to the Slack Marketplace. We recommend sharing your code as a public repository in order to share custom steps in Bolt apps.

+# Modals
+
+If you're learning about Slack apps, modals, or slash commands for the first time, you've come to the right place! In this tutorial, we'll take a look at setting up your very own server using GitHub Codespaces, then using that server to run your Slack app built with the [**Bolt for Python framework**](https://github.com/SlackAPI/bolt-python).
+
+:::info[GitHub Codespaces]
+GitHub Codespaces is an online IDE that allows you to work on code and host your own server at the same time. While Codespaces is good for testing and development purposes, it should not be used in production.
+
+:::
+
+At the end of this tutorial, your final app will look like this:
+
+![announce](/img/bolt-python/announce.gif)
+
+And will make use of these Slack concepts:
+* [**Block Kit**](/block-kit/) is a UI framework for Slack apps that allows you to create beautiful, interactive messages within Slack. If you've ever seen a message in Slack with buttons or a select menu, that's Block Kit.
+* [**Modals**](/surfaces/modals) are a pop-up window that displays right in Slack. They grab the attention of the user, and are normally used to prompt users to provide some kind of information or input in a form.
+* [**Slash Commands**](/interactivity/implementing-slash-commands) allow you to invoke your app within Slack by just typing into the message composer box. e.g. `/remind`, `/topic`.
+
+If you're familiar with using Heroku you can also deploy directly to Heroku with the following button.
+
+[![Deploy](https://www.herokucdn.com/deploy/button.svg)](https://www.heroku.com/deploy?template=https://github.com/wongjas/modal-example)
+
+---
+
+## Setting up your app within App Settings {#setting-up-app-settings}
+
+You'll need to create an app and configure it properly within App Settings before using it.
+
+1. [Create a new app](https://api.slack.com/apps/new), click `From a Manifest`, and choose the workspace that you want to develop on. Then copy the following JSON object; it describes the metadata about your app, like its name, its bot display name and permissions it will request.
+
+```json
+{
+    "display_information": {
+        "name": "Intro to Modals"
+    },
+    "features": {
+        "bot_user": {
+            "display_name": "Intro to Modals",
+            "always_online": false
+        },
+        "slash_commands": [
+            {
+                "command": "/announce",
+                "description": "Makes an announcement",
+                "should_escape": false
+            }
+        ]
+    },
+    "oauth_config": {
+        "scopes": {
+            "bot": [
+                "chat:write",
+                "commands"
+            ]
+        }
+    },
+    "settings": {
+        "interactivity": {
+            "is_enabled": true
+        },
+        "org_deploy_enabled": false,
+        "socket_mode_enabled": true,
+        "token_rotation_enabled": false
+    }
+}
+```
+
+2. Once your app has been created, scroll down to `App-Level Tokens` and create a token that requests for the [`connections:write`](/reference/scopes/connections.write) scope, which allows you to use [Socket Mode](/apis/events-api/using-socket-mode), a secure way to develop on Slack through the use of WebSockets. Copy the value of your app token and keep it for safe-keeping.
+
+3. Install your app by heading to `Install App` in the left sidebar. Hit `Allow`, which means you're agreeing to install your app with the permissions that it is requesting. Be sure to copy the token that you receive, and keep it somewhere secret and safe.
+
+## Starting your Codespaces server {#starting-server}
+
+1. Log into GitHub and head to this [repository](https://github.com/wongjas/modal-example).
+
+2. Click the green `Code` button and hit the `Codespaces` tab and then `Create codespace on main`.  This will bring up a code editor within your browser so you can start coding.  
+
+## Understanding the project files {#understanding-files}
+
+Within the project you'll find a `manifest.json` file. This is a a configuration file used by Slack apps. With a manifest, you can create an app with a pre-defined configuration, or adjust the configuration of an existing app.
+
+The `simple_modal_example.py` Python script contains the code that powers your app. If you're going to tinker with the app itself, take a look at the comments found within the `simple_modal_example.py` file!
+
+The `requirements.txt` file contains the Python package dependencies needed to run this app.
+
+:::info[This repo contains optional Heroku-specific configurations]
+
+The `app.json` file defines your Heroku app configuration including environment variables and deployment settings, to allow your app to deploy with one click. `Procfile` is a Heroku-specific file that tells Heroku what command to run when starting your app — in this case a Python script would run as a `worker` process. If you aren't deploying to Heroku, you can ignore both these files.
+

+
+## Adding tokens {#adding-tokens}
+
+1. Open a terminal up within the browser's editor. 
+
+2. Grab the app and bot tokens that you kept safe. We're going to set them as environment variables.
+
+```bash
+export SLACK_APP_TOKEN=<YOUR-APP-TOKEN-HERE>
+export SLACK_BOT_TOKEN=<YOUR-BOT-TOKEN-HERE>
+```
+
+## Running the app {#running-app}
+
+1. Activate a virtual environment for your Python packages to be installed.
+
+```bash
+# Setup your python virtual environment
+python3 -m venv .venv
+source .venv/bin/activate
+```
+
+2. Install the dependencies from the `requirements.txt` file.
+
+
+```bash
+# Install the dependencies
+pip install -r requirements.txt
+```
+
+3. Start your app using the `python3 simple_modal_example.py` command. 
+
+```bash
+# Start your local server
+python3 simple_modal_example.py
+```
+
+4. Now that your app is running, you should be able to see it within Slack. Test this by heading to Slack and typing `/announce`.
+
+All done! 🎉 You've created your first slash command using Block Kit and modals! The world is your oyster; play around with [Block Kit Builder](https://app.slack.com/block-kit-builder) and create more complex modals and place them in your code to see what happens!

+title: Create a Salesforce order confirmation app
+---
+
+In this tutorial, you'll use the [Bolt for Python](/tools/bolt-python/) framework and [Block Kit Builder](https://app.slack.com/block-kit-builder) to create an order confirmation app that links to a system of record, like Salesforce.
+	
+The Slack app will:
+* allow users to enter order numbers from within Slack, along with some additional order information,
+* post that information to a Slack channel, and
+* send the information to the system of record. 
+	
+End users will be able to enter information across devices, as many will likely be using a mobile device. 
+
+Along the way, you'll learn how to use the Bolt for Python starter app template as a jumping off point for your own custom apps. Let's begin!
+	
+:::warning[Consider the following]
+	
+This tutorial was created for educational purposes within a Slack workshop. As a result, it has not been tested quite as rigorously as our sample apps. Proceed carefully if you'd like to use a similar app in production.
+
+:::
+
+## Getting started
+
+### Installing the Slack CLI
+
+If you don't already have the Slack CLI, install it from your terminal: navigate to the installation guide ([for Mac and Linux](/tools/slack-cli/guides/installing-the-slack-cli-for-mac-and-linux) or [for Windows](/tools/slack-cli/guides/installing-the-slack-cli-for-windows)) and follow the steps.
+
+### Cloning the starter app
+
+Once installed, use the command `slack create` to get started with the Bolt for Python [starter template](https://github.com/slack-samples/bolt-python-starter-template). Alternatively, you can clone the template using Git.
+
+You can remove the portions from the template that are not used within this tutorial to make things a bit cleaner for yourself. To do this, open your project in VS Code (you can do this from the terminal with the `code .` command) and delete the `commands`, `events`, and `shortcuts` folders from the `/listeners` folder. You can also do the same to the corresponding folders within the `/listeners/tests` folder as well. Finally, remove the imports of these files from the `/listeners/__init__.py` file.
+
+## Creating your app
+
+We’ll use the contents of the `manifest.json` file below. This file describes the metadata associated with your app, like its name and permissions that it requests.
+
+These values are used to create an app in one of two ways: 
+
+- **With the Slack CLI**: Save the contents of the file to your project's `manifest.json` file then skip ahead to [starting your app](#starting-your-app).
+- **With app settings**: Copy the contents of the file and [create a new app](https://api.slack.com/apps/new). Next, choose **From a manifest** and follow the prompts, pasting the manifest file contents you copied.
+
+```json
+{
+  "_metadata": {
+      "major_version": 1,
+      "minor_version": 1
+  },
+  "display_information": {
+      "name": "Delivery Tracker App" 
+  },
+  "features": {
+      "bot_user": {
+          "display_name": "Delivery Tracker App",
+          "always_online": false
+      }
+  },
+  "oauth_config": {
+      "scopes": {
+          "bot": [
+              "channels:history",
+              "chat:write"
+          ]
+      }
+  },
+  "settings": {
+      "event_subscriptions": {
+          "bot_events": [
+              "message.channels"
+          ]
+      },
+      "interactivity": {
+          "is_enabled": true
+      },
+      "org_deploy_enabled": false,
+      "socket_mode_enabled": true,
+      "token_rotation_enabled": false
+  }
+}
+```
+
+### Tokens
+
+Once your app has been created, scroll down to **App-Level Tokens** on the **Basic Information** page and create a token that requests the [`connections:write`](/reference/scopes/connections.write) scope. This token will allow you to use [Socket Mode](/apis/events-api/using-socket-mode), which is a secure way to develop on Slack through the use of WebSockets. Save the value of your app token and store it in a safe place (we’ll use it in the next step).
+
+### Install app
+
+Still in the app settings, navigate to the **Install App** page in the left sidebar. Install your app. When you press **Allow**, this means you’re agreeing to install your app with the permissions that it’s requesting. Copy the bot token that you receive as well and store this in a safe place as well for subsequent steps.
+
+## Saving credentials
+
+Within a terminal of your choice, set the two tokens from the previous step as environment variables using the commands below. Make sure not to mix these two up, `SLACK_APP_TOKEN` will start with “xapp-“ and `SLACK_BOT_TOKEN` will start with “xoxb-“.
+
+For macOS:
+
+```bash
+export SLACK_APP_TOKEN=<YOUR-APP-TOKEN-HERE>
+export SLACK_BOT_TOKEN=<YOUR-BOT-TOKEN-HERE>
+```
+
+For Windows Command Prompt:
+
+```cmd
+set SLACK_APP_TOKEN=<YOUR-APP-TOKEN-HERE>
+set SLACK_BOT_TOKEN=<YOUR-BOT-TOKEN-HERE>
+```
+
+For Windows PowerShell:
+
+```powershell
+$env:SLACK_APP_TOKEN="YOUR-APP-TOKEN-HERE"
+$env:SLACK_BOT_TOKEN="YOUR-BOT-TOKEN-HERE"
+```
+
+## Starting your app {#starting-your-app}
+
+Run the following commands to activate a virtual environment for your Python packages to be installed, install the dependencies, and start your app.
+
+```bash
+# Setup your python virtual environment
+python -m venv .venv
+source .venv/bin/activate
+
+# Install the dependencies
+pip install -r requirements.txt
+
+# Start your local server
+slack run
+```
+
+If you're not using the Slack CLI, a different `python` command can be used to start your app instead:
+	
+```sh
+python app.py
+```
+
+Now that your app is running, you should be able to see it within Slack. In Slack, create a channel that you can test in and try inviting your bot to it using the `/invite @Your-app-name-here` command. Check that your app works by saying “hi” in the channel where your app is, and you should receive a message back from it. If you don’t, ensure you completed all the steps above.
+
+## Coding the app
+
+We'll make four changes to the app:
+
+* Update the “hi” message to something more interesting and interactive
+* Handle when the wrong delivery ID button is pressed
+* Handle when the correct delivery IDs are sent and bring up a modal for more information
+* Send the information to all of the places needed when the form is submitted (including third-party locations)
+
+For all of these steps, we will use [Block Kit Builder](https://app.slack.com/block-kit-builder), a tool that helps you create messages, modals and other surfaces within Slack. Open [Block Kit Builder](https://app.slack.com/block-kit-builder), take a look, and play around! We’ll create some views next.
+
+### Updating the "hi" message
+
+The first thing we want to do is change the “hi, how are you?” message from our app into something more useful. Here’s a `blocks` object built with Block Kit Builder:
+
+```json
+
+    "blocks": [
+        {
+            "type": "section",
+            "text": {
+                "type": "mrkdwn",
+                "text": "Confirm *{delivery_id}* is correct?"
+            }
+        },
+        {
+            "type": "actions",
+            "elements": [
+                {
+                    "type": "button",
+                    "text": {
+                        "type": "plain_text",
+                        "text": "Correct",
+                        "emoji": true
+                    },
+                    "style": "primary",
+                    "action_id": "approve_delivery"
+                },
+                {
+                    "type": "button",
+                    "text": {
+                        "type": "plain_text",
+                        "text": "Not correct",
+                        "emoji": true
+                    },
+                    "style": "danger",
+                    "action_id": "deny_delivery"
+                }
+            ]
+        }
+    ]
+
+```
+
+Take the function below and place your blocks within the blocks dictionary `[]`.
+
+```python
+def delivery_message_callback(context: BoltContext, say: Say, logger: Logger):
+    try:
+        delivery_id = context["matches"][0]
+        say( 
+            blocks=[] # insert your blocks here
+        )
+    except Exception as e:
+        logger.error(e)
+```
+
+Update the payload: 
+* Remove the initial blocks key and convert any boolean true values to `True` to fit with Python conventions.
+* If you see variables within `{}` brackets, this is part of an f-string, which allows you to insert variables within strings in a clean manner. Place the `f` character before these strings like this:
+
+```python
+{
+    "type": "section",
+    "text": {
+        "type": "mrkdwn",
+        "text": f"Confirm *{delivery_id}* is correct?", # place the "f" character here at the beginning of the string
+    },
+},
+```
+
+Place all of this in the `sample_message.py` file.
+
+Next, you’ll need to register this listener to respond when a message is sent in the channel with your app. Head to `messages/__init__.py` and overwrite the function there with the one below, which registers the  function. Don’t forget to add the import to the callback function as well!
+
+```python
+from .sample_message import delivery_message_callback # import the function to this file
+
+def register(app: App):
+    # This regex will capture any number letters followed by dash 
+    # and then any number of digits, our "confirmation number" e.g. ASDF-1234
+    app.message(re.compile(r"[A-Za-z]+-\d+"))(delivery_message_callback) ## add this line!
+```
+
+Now, restart your server to bring in the new code and test that your function works by sending an order confirmation ID, like `HWOA-1524`, in your testing channel. Your app should respond with the message you created within Block Kit Builder.
+
+### Handling an incorrect delivery ID
+
+Notice that if you try to click on either of the buttons within your message, nothing will happen. This is because we have yet to create a function to handle the button click. Let’s start with the `Not correct` button first.
+
+1. Head to Block Kit Builder once again. We want to build a message that lets the user know that the wrong order ID has been submitted. Here's a [section](/reference/block-kit/blocks/section-block) block to get you started:
+
+```json
+    "blocks": [
+        {
+            "type": "section",
+            "text": {
+                "type": "mrkdwn",
+                "text": "Delivery *{delivery_id}* was incorrect ❌"
+            }
+        }
+    ]
+```
+
+View this block in Block Kit Builder [here](https://app.slack.com/block-kit-builder/#%7B%22blocks%22:%5B%7B%22type%22:%22section%22,%22text%22:%7B%22type%22:%22mrkdwn%22,%22text%22:%22Delivery%20*%7Bdelivery_id%7D*%20was%20incorrect%20%E2%9D%8C%22%7D%7D%5D%7D).
+
+2. Once you have something that you like, add it to the function below and place the function within the `actions/sample_action.py` file. Remember to make any strings with variables into f-strings!
+
+```python
+def deny_delivery_callback(ack, body, client, logger: Logger):
+    try:
+        ack()
+        delivery_id = body["message"]["text"].split("*")[1]
+
+        # Calls the chat.update function to replace the message, 
+        # preventing it from being pressed more than once.
+        client.chat_update(
+            channel=body["container"]["channel_id"],
+            ts=body["container"]["message_ts"],
+            blocks=[], # Add your blocks here!
+        )
+
+        logger.info(f"Delivery denied by user {body['user']['id']}")
+    except Exception as e:
+        logger.error(e)
+```
+
+This function will call the [`chat.update`](/reference/methods/chat.update) Web API method, which will update the original message with buttons, to the one that we created previously. This will also prevent the message from being pressed more than once.
+
+3. Make the connection to this function again within the `actions/__init__.py` folder with the following code:
+
+```python
+from slack_bolt import App
+from .sample_action import sample_action_callback # This can be deleted
+from .sample_action import deny_delivery_callback
+
+def register(app: App):
+    app.action("sample_action_id")(sample_action_callback) # This can be deleted
+    app.action("deny_delivery")(deny_delivery_callback) # Add this line
+```
+
+Test out your app by sending in a confirmation number into your channel and clicking the `Not correct` button. If the message is updated, then you’re good to go onto the next step.
+
+### Handling a correct delivery ID
+
+The next step is to handle the `Confirm` button. In this case, we’re going to pull up a modal instead of just a message.
+
+1. Using the following modal as a base; create a modal that captures the kind of information that you need.
+
+```json
+{
+    "title": {
+        "type": "plain_text",
+        "text": "Approve Delivery"
+    },
+    "submit": {
+        "type": "plain_text",
+        "text": "Approve"
+    },
+    "type": "modal",
+    "callback_id": "approve_delivery_view",
+    "private_metadata": "{delivery_id}",
+    "blocks": [
+        {
+            "type": "section",
+            "text": {
+                "type": "mrkdwn",
+                "text": "Approving delivery *{delivery_id}*"
+            }
+        },
+        {
+            "type": "input",
+            "block_id": "notes",
+            "label": {
+                "type": "plain_text",
+                "text": "Additional delivery notes"
+            },
+            "element": {
+                "type": "plain_text_input",
+                "action_id": "notes_input",

+                    "type": "plain_text",
+                    "text": "Add notes..."
+                }
+            },
+            "optional": true
+        },
+        {
+            "type": "input",

+            "element": {
+                "type": "plain_text_input",
+                "action_id": "location_input",

+                    "text": "Enter the location details..."
+                }
+            },
+            "optional": true
+        },
+        {
+            "type": "input",
+            "block_id": "channel",
+            "label": {
+                "type": "plain_text",
+                "text": "Notification Channel"
+            },
+            "element": {
+                "type": "channels_select",
+                "action_id": "channel_select",
+                "placeholder": {
+                    "type": "plain_text",
+                    "text": "Select channel for notifications"
+                }
+            },
+            "optional": false
+        }
+    ]
+}

+2. Within the `actions/sample_action.py` file, add the following function, replacing the view with the one you created above. Again, any strings with variables will be updated to f-strings and also any booleans will need to be capitalized.
+
+```python

+        delivery_id = body["message"]["text"].split("*")[1]
+        # Updates the original message so you can't press it twice
+        client.chat_update(
+            channel=body["container"]["channel_id"],
+            ts=body["container"]["message_ts"],
+            blocks=[
+                {
+                    "type": "section",
+                    "text": {
+                        "type": "mrkdwn",
+                        "text": f"Processed delivery *{delivery_id}*...",
+                    },
+                }
+            ],
+        )
+
+        # Open a modal to gather information from the user
+        client.views_open(
+            trigger_id=body["trigger_id"],
+            view={} # Add your view here
+        )
+
+        logger.info(f"Approval modal opened by user {body['user']['id']}")
+    except Exception as e:
+        logger.error(e)
+```
+
+Similar to the `deny` button, we need to hook up all the connections.  Your `actions/__init__.py` should look something like this:
+
+```python
+from slack_bolt import App
+from .sample_action import deny_delivery_callback
+from .sample_action import approve_delivery_callback
+
+
+def register(app: App):
+    app.action("approve_delivery")(approve_delivery_callback)
+    app.action("deny_delivery")(deny_delivery_callback)
+```
+
+Test your app by typing in a confirmation number in channel, click the confirm button and see if the modal comes up and you are able to capture information from the user.
+
+### Submitting the form
+
+Lastly, we’ll handle the submission of the form, which will trigger two things. We want to send the information into the specified channel, which will let the user know that the form was successful, as well as send the information into our system of record, Salesforce.
+
+1. Here’s a simple example of a message that you can use to present the information in channel. 
+
+```json
+    "blocks": [
+        {
+            "type": "section",
+            "text": {
+                "type": "mrkdwn",
+                "text": "✅ Delivery *{delivery_id}* approved:"
+            }
+        },
+        {
+            "type": "section",
+            "text": {
+                "type": "mrkdwn",
+                "text": "*Delivery Notes:*\n{notes or 'None'}"
+            }
+        },
+        {
+            "type": "section",
+            "text": {
+                "type": "mrkdwn",
+                "text": "*Delivery Location:*\n{loc or 'None'}"
+            }
+        }
+    ]
+```
+
+View this in Block Kit Builder [here](https://app.slack.com/block-kit-builder/?1#%7B%22blocks%22:%5B%7B%22type%22:%22section%22,%22text%22:%7B%22type%22:%22mrkdwn%22,%22text%22:%22%E2%9C%85%20Delivery%20*%7Bdelivery_id%7D*%20approved:%22%7D%7D,%7B%22type%22:%22section%22,%22text%22:%7B%22type%22:%22mrkdwn%22,%22text%22:%22*Delivery%20Notes:*%5Cn%7Bnotes%20or%20'None'%7D%22%7D%7D,%7B%22type%22:%22section%22,%22text%22:%7B%22type%22:%22mrkdwn%22,%22text%22:%22*Delivery%20Location:*%5Cn%7Bloc%20or%20'None'%7D%22%7D%7D%5D%7D). Modify it however you like and then place it within the code below in the `/views/sample_views.py` file.
+
+```python
+def handle_approve_delivery_view(ack, client, view, logger: Logger):
+    try:
+        ack()
+
+        delivery_id = view["private_metadata"]
+        values = view["state"]["values"]
+        notes = values["notes"]["notes_input"]["value"]
+        loc = values["location"]["location_input"]["value"]
+        channel = values["channel"]["channel_select"]["selected_channel"]
+
+        client.chat_postMessage(
+            channel=channel,
+            blocks=[], ## Add your message here
+        )
+
+    except Exception as e:
+        logger.error(f"Error in approve_delivery_view: {e}")
+```
+
+2. Making the connections in the `/views/__init__.py `file, we can test that this works by sending a message once again in our test channel.
+
+```python
+from slack_bolt import App
+from .sample_view import handle_approve_delivery_view
+
+def register(app: App):
+    app.view("sample_view_id")(sample_view_callback) # This can be deleted
+    app.view("approve_delivery_view")(handle_approve_delivery_view) ## Add this line
+```
+
+3. Let’s also send the information to Salesforce. There are [several ways](https://github.com/simple-salesforce/simple-salesforce?tab=readme-ov-file#examples) for you to access Salesforce through its API, but in this example, we’ve utilized `username`, `password` and `token` parameters. If you need help with getting your API token for Salesforce, take a look at [this article](https://help.salesforce.com/s/articleView?id=xcloud.user_security_token.htm&type=5). You’ll need to add these values as environment variables like we did earlier with our Slack tokens. You can use the following commands:
+
+```bash
+export SF_USERNAME=<YOUR-USERNAME>
+export SF_PASSWORD=<YOUR-PASSWORD>
+export SF_TOKEN=<YOUR-SFDC-TOKEN>
+```
+
+4. We’re going to use assume that order information is stored in the Order object and that the confirmation IDs map to the 8-digit Order numbers within Salesforce. Given that assumption, we need to make a query to find the correct object, add the inputted information, and we’re done. Place this functionality before the last excerpt within the `/views/sample_views.py` file.
+
+```python
+# Extract just the numeric portion from delivery_id
+        delivery_number = "".join(filter(str.isdigit, delivery_id))
+
+        # Update Salesforce order object
+        try:
+            sf = Salesforce(
+                username=os.environ.get("SF_USERNAME"),
+                password=os.environ.get("SF_PASSWORD"),
+                security_token=os.environ.get("SF_TOKEN"),
+            )
+
+            # Assuming delivery_id maps to Salesforce Order number
+            order = sf.query(f"SELECT Id FROM Order WHERE OrderNumber = '{delivery_number}'")  # noqa: E501
+            if order["records"]:
+                order_id = order["records"][0]["Id"]
+                sf.Order.update(
+                    order_id,
+                    {
+                        "Status": "Delivered",
+                        "Description": notes,
+                        "Shipping_Location__c": loc,
+                    },
+                )
+                logger.info(f"Updated order {delivery_id}")
+            else:
+                logger.warning(f"No order found for {delivery_id}")
+
+        except Exception as sf_error:
+            logger.error(f"Update failed for order {delivery_id}: {sf_error}")
+            # Continue execution even if Salesforce update fails
+```
+
+You’ll also need to add the two imports that are found within this code to the top of the file.
+
+```python
+import os
+from simple_salesforce import Salesforce
+```
+
+With these imports, add `simple_salesforce` to your `requirements.txt` file, then install that package with the following command once again.
+
+```bash
+pip install -r requirements.txt
+```

+
+## Testing your app
+
+Test your app one last time, and you’re done!
+
+Congratulations! You’ve built an app using [Bolt for Python](/tools/bolt-python/) that allows you to send information into Slack, as well as into a third-party service. While there are more features you can add to make this a more robust app, we hope that this serves as a good introduction into connecting services like Salesforce using Slack as a conduit.

+# アクション
+
+## アクションのリスニング
+
+Bolt アプリは `action` メソッドを用いて、ボタンのクリック、メニューの選択、メッセージショートカットなどのユーザーのアクションをリッスンすることができます。
+
+アクションは `str` 型または `re.Pattern` 型の `action_id` でフィルタリングできます。`action_id` は、Slack プラットフォーム上のインタラクティブコンポーネントを区別する一意の識別子として機能します。
+
+`action()` を使ったすべての例で `ack()` が使用されていることに注目してください。アクションのリスナー内では、Slack からのリクエストを受信したことを確認するために、`ack()` 関数を呼び出す必要があります。これについては、[リクエストの確認](/tools/bolt-python/concepts/acknowledge)セクションで説明しています。
+
+指定可能な引数の一覧は[モジュールドキュメント](https://docs.slack.dev/tools/bolt-python/reference/kwargs_injection/args.html)を参考にしてください。
+
+```python
+# 'approve_button' という action_id のブロックエレメントがトリガーされるたびに、このリスナーが呼び出させれる
+@app.action("approve_button")
+def update_message(ack):
+    ack()
+    # アクションへの反応としてメッセージを更新
+```
+
+### 制約付きオブジェクトを使用したアクションのリスニング
+
+制約付きのオブジェクトを使用すると、`block_id` と `action_id` をそれぞれ、または任意に組み合わせてリッスンできます。オブジェクト内の制約は、`str` 型または `re.Pattern` 型で指定できます。
+
+```python
+# この関数は、block_id が 'assign_ticket' に一致し
+# かつ action_id が 'select_user' に一致する場合にのみ呼び出される
+@app.action({
+    "block_id": "assign_ticket",
+    "action_id": "select_user"
+})
+def update_message(ack, body, client):
+    ack()
+
+    if "container" in body and "message_ts" in body["container"]:
+        client.reactions_add(
+            name="white_check_mark",
+            channel=body["channel"]["id"],
+            timestamp=body["container"]["message_ts"],
+        )
+```
+
+## アクションへの応答
+
+アクションへの応答には、主に 2 つの方法があります。1 つ目の最も一般的なやり方は `say()` を使用する方法です。そのリクエストが発生した会話（チャンネルや DM）にメッセージを返します。
+
+2 つ目は、`respond()` を使用する方法です。これは、アクションに関連づけられた `response_url` を使ったメッセージ送信を行うためのユーティリティです。
+
+指定可能な引数の一覧は[モジュールドキュメント](https://docs.slack.dev/tools/bolt-python/reference/kwargs_injection/args.html)を参考にしてください。
+
+```python
+# 'approve_button' という action_id のインタラクティブコンポーネントがトリガーされると、このリスナーが呼ばれる
+@app.action("approve_button")
+def approve_request(ack, say):
+    # アクションのリクエストを確認
+    ack()
+    say("Request approved 👍")
+```
+
+### respond() の利用
+
+`respond()` は `response_url` を使って送信するときに便利なメソッドで、これらと同じような動作をします。投稿するメッセージのペイロードには、全ての[メッセージペイロードのプロパティ](/messaging/#payloads)とオプションのプロパティとして `response_type`（値は `"in_channel"` または `"ephemeral"`）、`replace_original`、`delete_original`、`unfurl_links`、`unfurl_media` などを指定できます。こうすることによってアプリから送信されるメッセージは、やり取りの発生元に反映されます。
+
+```python
+# 'user_select' という action_id を持つアクションのトリガーをリッスン
+@app.action("user_select")
+def select_user(ack, action, respond):
+    ack()
+    respond(f"You selected <@{action['selected_user']}>")

 Bolt for Python によって `slack/oauth_redirect` という**リダイレクト URL** が生成されます。Slack はアプリのインストールフローを完了させたユーザーをこの URL にリダイレクトします。この**リダイレクト URL** は、アプリの設定の「**OAuth and Permissions**」であらかじめ追加しておく必要があります。この URL は、後ほど説明するように `OAuthSettings` というコンストラクタの引数で指定することもできます。

+# Bolt 入門ガイド
+
+このガイドでは、Bolt for Python を使った Slack アプリの設定と起動の方法について説明します。ここで説明する手順では、まず新しい Slack アプリを作成し、ローカルの開発環境をセットアップし、Slack ワークスペースからのメッセージをリッスンして応答するアプリを開発するという流れになります。
+
+
+この手順を全て終わらせたら、あなたはきっと ⚡️[Slack アプリのはじめ方](https://github.com/slackapi/bolt-python/tree/main/examples/getting_started)のサンプルアプリを動作させたり、それに変更を加えたり、自分のアプリを作ったりすることができるようになるでしょう。
+
+---
+
+### アプリを作成する {#create-an-app}
+最初にやるべきこと : Bolt での開発を始める前に、[Slack アプリを作成](https://api.slack.com/apps/new)します。
+
+:::tip[通常の業務の妨げにならないよう、別の開発用のワークスペースを使用することをおすすめします。[新しいワークスペースは無料で作成できます](https://slack.com/get-started#create)]
+
+:::
+
+アプリ名を入力し（_後で変更可能_）、インストール先のワークスペースを選択して「`Create App`」ボタンをクリックすると、アプリの **Basic Information** ページが表示されます。
+
+このページでは、アプリの概要や重要な認証情報を確認できます。これらの情報は後ほど参照します。
+
+![Basic Information ページ](/img/bolt-python/basic-information-page.png "Basic Information ページ")
+
+ひと通り確認して、アプリのアイコンと説明を追加したら、アプリのプロジェクトの構成 🔩 を始めましょう。
+
+---
+
+### トークンとアプリのインストール {#tokens-and-installing-apps}
+Slack アプリでは、[Slack API へのアクセスの管理に OAuth を使用します](/authentication/installing-with-oauth)。アプリがインストールされると、トークンが発行されます。アプリはそのトークンを使って API メソッドを呼び出すことができます。
+
+Slack アプリで使用できるトークンには、ユーザートークン（`xoxp`）とボットトークン（`xoxb`）、アプリレベルトークン（`xapp`）の 3 種類があります。
+- [ユーザートークン](/authentication/tokens#user) を使用すると、アプリをインストールまたは認証したユーザーに成り代わって API メソッドを呼び出すことができます。1 つのワークスペースに複数のユーザートークンが存在する可能性があります。
+- [ボットトークン](/authentication/tokens#bot) はボットユーザーに関連づけられ、1 つのワークスペースでは最初に誰かがそのアプリをインストールした際に一度だけ発行されます。どのユーザーがインストールを実行しても、アプリが使用するボットトークンは同じになります。_ほとんど_のアプリで使用されるのは、ボットトークンです。
+- [アプリレベルトークン](/authentication/tokens#app-level) は、全ての組織（とその配下のワークスペースでの個々のユーザーによるインストール）を横断して、あなたのアプリを代理するものです。アプリレベルトークンは、アプリの WebSocket コネクションを確立するためによく使われます。
+
+このガイドではボットトークンとアプリレベルトークンを使用します。
+
+1. 左サイドバーの「**OAuth & Permissions**」をクリックし、「**Bot Token Scopes**」セクションまで下にスクロールします。「**Add an OAuth Scope**」をクリックします。
+
+2. ここでは [`chat:write`](/reference/scopes/chat.write) というスコープのみを追加します。このスコープはアプリが参加しているチャンネルにメッセージを投稿することを許可します。
+
+3. OAuth & Permissions ページの一番上までスクロールし、「**Install App to Workspace**」をクリックします。Slack の OAuth 確認画面 が表示されます。この画面で開発用ワークスペースへのアプリのインストールを承認します。
+
+4. インストールを承認すると **OAuth & Permissions** ページが表示され、**Bot User OAuth Access Token** を確認できるでしょう。
+
+![OAuth トークン](/img/bolt-python/bot-token.png "ボット用 OAuth トークン")
+
+5. 次に「**Basic Informationのページ**」まで戻り、アプリレベルトークンのセクションまで下にスクロールし「**Generate Token and Scopes**」をクリックしてアプリレベルトークンを作成します。このトークンに `connections:write` のスコープを付与し、作成された `xapp` トークンを保存します。これらのトークンは後ほど利用します。
+
+6. 左サイドメニューの「**Socket Mode**」を有効にします。
+
+:::tip[トークンはパスワードと同様に取り扱い、[安全な方法で保管してください](/security)。アプリはこのトークンを使って Slack ワークスペースで投稿をしたり、情報の取得をしたりします。]
+
+:::
+
+---
+
+### プロジェクトをセットアップする {#setting-up-your-project}
+初期設定が終わったら、新しい Bolt プロジェクトのセットアップを行いましょう。このプロジェクトが、あなたのアプリのロジックを処理するコードを配置する場所となります。
+
+プロジェクトをまだ作成していない場合は、新しく作成しましょう。空のディレクトリを作成します。
+
+```shell
+mkdir first-bolt-app
+cd first-bolt-app
+```
+
+次に、プロジェクトの依存ライブラリを管理する方法として、[Python 仮想環境](https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/#creating-a-virtual-environment)を使ったおすすめの方法を紹介します。これはシステム Python に存在するパッケージとのコンフリクトを防ぐために推奨されている優れた方法です。[Python 3.7 以降](https://www.python.org/downloads/)の仮想環境を作成し、アクティブにしてみましょう。
+
+```shell
+python3 -m venv .venv
+source .venv/bin/activate
+```
+
+`python3` へのパスがプロジェクトの中を指していることを確かめることで、仮想環境がアクティブになっていることを確認できます（[Windows でもこれに似たコマンドが利用できます](https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/#activating-a-virtual-environment)）。
+
+```shell
+which python3
+# 出力結果: /path/to/first-bolt-app/.venv/bin/python3
+```
+
+Bolt for Python のパッケージを新しいプロジェクトにインストールする前に、アプリの設定時に作成された **ボットトークン** と **アプリレベルトークン** を保存しましょう。
+
+1. **OAuth & Permissions ページのボットトークン (xoxb) をコピー**して、新しい環境変数に保存します。以下のコマンド例は Linux と macOS で利用できます。[Windows でもこれに似たコマンドが利用できます](https://superuser.com/questions/212150/how-to-set-env-variable-in-windows-cmd-line/212153#212153)。
+```shell
+export SLACK_BOT_TOKEN=xoxb-<ボットトークン>
+```
+
+2. **Basic Information ページのアプリレベルトークン（xapp）をコピー**して、別の環境変数に保存します。
+```shell
+export SLACK_APP_TOKEN=<アプリレベルトークン>
+```
+:::warning[🔒 全てのトークンは安全に保管してください。]
+
+少なくともパブリックなバージョン管理にチェックインするようなことは避けるべきでしょう。また、上にあった例のように環境変数を介してアクセスするようにしてください。詳細な情報は [アプリのセキュリティのベストプラクティス](/security)のドキュメントを参照してください。
+
+:::
+
+完了したら、いよいよアプリを作っていきましょう。以下のコマンドを使って、仮想環境に Python の `slack_bolt` パッケージをインストールします。
+
+```shell
+pip install slack_bolt
+```
+
+このディレクトリに「`app.py`」という名前の新しいファイルを作成し、以下のコードを追加します。
+
+```python
+import os
+from slack_bolt import App
+from slack_bolt.adapter.socket_mode import SocketModeHandler
+
+# ボットトークンとソケットモードハンドラーを使ってアプリを初期化します
+app = App(token=os.environ.get("SLACK_BOT_TOKEN"))
+
+# アプリを起動します
+if __name__ == "__main__":
+    SocketModeHandler(app, os.environ["SLACK_APP_TOKEN"]).start()
+```
+
+このようにトークンさえあれば、最初の Bolt アプリを作成することができます。「`app.py`」という名前でファイルを保存して、コマンドラインで以下を実行します。
+
+```script
+python3 app.py
+```
+
+アプリが起動し、実行中であることが表示されるはずです 🎉
+
+---
+
+### イベントを設定する {#setting-up-events}
+アプリはワークスペース内の他のメンバーと同じように振る舞い、メッセージを投稿したり、絵文字リアクションを追加したり、イベントをリッスンして返答したりできます。
+
+Slack ワークスペースで発生するイベント（メッセージが投稿されたときや、メッセージに対するリアクションがつけられたときなど）をリッスンするには、[Events API を使って特定の種類のイベントをサブスクライブします](/apis/events-api/)。
+
+このチュートリアルの序盤でソケットモードを有効にしました。ソケットモードを使うことで、アプリが公開された HTTP エンドポイントを公開せずに Events API やインタラクティブコンポーネントを利用できるようになります。このことは、開発時やファイヤーウォールの裏からのリクエストを受ける際に便利です。HTTP での方式は、ホスティング環境にデプロイするアプリや Slack App Directory で配布されるアプリの開発・運用に適しています。
+
+それでは、このアプリがどのイベントをリッスンしたいかを Slack に伝えましょう。
+
+import Tabs from '@theme/Tabs';
+import TabItem from '@theme/TabItem';
+
+<Tabs groupId="socket-or-http">
+<TabItem value="socket-mode" label="Socket Mode">
+
+1. アプリの構成ページに移動します ([アプリ設定ページから](https://api.slack.com/apps) アプリをクリックします)。左側のメニューで **ソケット モード** に移動し、有効に切り替えます。
+
+2. [**基本情報**] に移動し、[アプリレベル トークン] セクションの下にスクロールして、[**トークンとスコープの生成**] をクリックしてアプリ トークンを生成します。このトークンに `connections:write` スコープを追加し、生成された `xapp` トークンを保存します。これはすぐに使用します。
+
+3. 最後に、聞きたいイベントを Slack に伝えます。 **イベント サブスクリプション** で、**イベントを有効にする** というラベルのスイッチを切り替えます。
+
+イベントが発生すると、そのイベントをトリガーしたユーザーやイベントが発生したチャンネルなど、イベントに関する情報が Slack からアプリに送信されます。アプリではこれらの情報を処理して、適切な応答を返します。
+
+</TabItem>
+<TabItem value="http" label="HTTP">
+
+1. アプリ構成ページに戻ります ([アプリ管理ページから](https://api.slack.com/apps) アプリをクリックします)。左側のサイドバーで [**イベント サブスクリプション**] をクリックします。 **イベントを有効にする**というラベルの付いたスイッチを切り替えます。
+
+2. リクエスト URL を追加します。 Slack は、イベントに対応する HTTP POST リクエストをこの [リクエスト URL](/apis/events-api/#subscribing) に送信します。 Bolt は、`/slack/events` パスを使用して、すべての受信リクエスト (ショートカット、イベント、対話性ペイロードなど) をリッスンします。アプリ構成内でリクエスト URL を構成する場合は、`/slack/events` を追加します。 「https://あなたのドメイン/slack/events」。 💡 Bolt アプリが実行されている限り、URL は検証されるはずです。
+
+:::tip
+
+ローカル開発の場合、ngrok などのプロキシ サービスを使用してパブリック URL を作成し、リクエストを開発環境にトンネリングできます。このトンネルの作成方法については、[ngrok のスタート ガイド](https://ngrok.com/docs#getting-started-expose) を参照してください。アプリをホスティングする際には、Slack 開発者がアプリをホストするために使用する最も一般的なホスティング プロバイダーを [API サイト](/app-management/hosting-slack-apps) に集めました。
+
+:::
+
+</TabItem>
+</Tabs>
+
+左側のサイドバーから **Event Subscriptions** にアクセスして、機能を有効にしてください。 **Subscribe to Bot Events** 配下で、ボットが受け取れるイベントを追加することができます。4つのメッセージに関するイベントがあります。
+- [`message.channels`](/reference/events/message.channels) アプリが参加しているパブリックチャンネルのメッセージをリッスン
+- [`message.groups`](/reference/events/message.groups) アプリが参加しているプライベートチャンネルのメッセージをリッスン
+- [`message.im`](/reference/events/message.im) あなたのアプリとユーザーのダイレクトメッセージをリッスン
+- [`message.mpim`](/reference/events/message.mpim) あなたのアプリが追加されているグループ DM をリッスン
+
+ボットが参加するすべての場所のメッセージをリッスンさせるには、これら 4 つのメッセージイベントをすべて選択します。ボットにリッスンさせるメッセージイベントの種類を選択したら、「**Save Changes**」ボタンをクリックします。
+
+---
+
+### メッセージをリッスンして応答する {#listening-and-responding-to-a-message}
+アプリにロジックを組み込む準備が整いました。まずは `message()` メソッドを使用して、メッセージのリスナーをアタッチしましょう。
+
+次の例では、アプリが参加するチャンネルとダイレクトメッセージに投稿されるすべてのメッセージをリッスンし、「こんにちは」というメッセージに応答を返します。
+
+<Tabs groupId="socket-or-http">
+<TabItem value="socket-mode" label="Socket Mode">
+
+```python
+import os
+from slack_bolt import App

+  </TabItem>
+  <TabItem value="http" label="HTTP">

+if __name__ == "__main__":
+    app.start(port=int(os.environ.get("PORT", 3000)))
+```
+
+  </TabItem>
+</Tabs>
+
+アプリを再起動して、ボットユーザーが参加しているチャンネル・ダイレクトメッセージに「こんにちは」というメッセージを投稿すると、アプリが返答を返すでしょう。
+
+これはごく基本的なコード例ですが、最終的にやりたいことを実現するためにアプリをカスタマイズしていく土台として利用できます。次は、シンプルなテキストの返答を送信する代わりにメッセージ内にボタンを表示するという、もう少しインタラクティブな動作を試してみましょう。
+
+---
+
+### アクションを送信して応答する {#sending-and-responding-to-actions}
+
+インタラクティブ機能を有効にすると、ボタン、選択メニュー、日付ピッカー、モーダル、ショートカットなどの機能が利用できるようになります。アプリ設定ページの「**Interactivity & Shortcuts**」にアクセスしてください。
+
+<Tabs groupId="socket-or-http">
+<TabItem value="socket-mode" label="Socket Mode">
+
+ソケット モードをオンにすると、基本的な対話機能がデフォルトで有効になるため、それ以上の操作は必要ありません。

+</TabItem>
+<TabItem value="http" label="HTTP">
+
+イベントと同様に、Slack がアクション (*ユーザーがボタンをクリックした* など) を送信するには、URL を指定する必要があります。アプリ構成ページに戻り、左側にある **対話性とショートカット** をクリックします。別の **リクエスト URL** ボックスがあることがわかります。
+
+:::tip
+
+ソケットモードを有効にしているとき、デフォルトで基本的なインタラクティブ機能が有効になっていることに気づくでしょう。追加のアクションは不要です。もし HTTP を使っている場合、Slack からのイベント送信先である Request URL を設定する必要があります。

+</TabItem>
+</Tabs>
+
+インタラクティビティが有効化されていれば、ショートカット、モーダル、インタラクティブコンポーネント (例：ボタン、選択メニュー、日付ピッカー) とのインタラクションはイベントとしてあなたのアプリに送信されます。
+
+それでは、アプリのコードに戻り、これらのイベントを処理する為のロジックを追加しましょう。
+- まず、インタラクティブコンポーネント（ここではボタン）を含んだメッセージをアプリから送信します。
+- 次に、ユーザーから返されるボタンクリックのアクションをリッスンし、それに応答します。
+
+以下のコードの後の部分を編集し、文字列だけのメッセージの代わりに、ボタンを含んだメッセージを送信するようにしてみます。

+`say()` の中の値を `blocks` という配列のオブジェクトに変えました。ブロックは Slack メッセージを構成するコンポーネントであり、テキストや画像、日付ピッカーなど、さまざまなタイプのブロックがあります。この例では `accessory` に `button` を持たせた「section」のブロックを、アプリからの応答に含めています。`blocks` を使用する場合、`text` は通知やアクセシビリティのためのフォールバックとなります。
+
+ボタンを含む `accessory` オブジェクトでは、`action_id` を指定していることがわかります。これは、ボタンを一意に示す識別子として機能します。これを使って、アプリをどのアクションに応答させるかを指定できます。

+
+* 基本的な概念について読んでみてください。Bolt アプリがアクセスできるさまざまメソッドや機能について知ることができます。
+* [`app.event()` メソッド](/tools/bolt-python/concepts/event-listening)でボットがリッスンできるイベントをほかにも試してみましょう。すべてのイベントの一覧は [API サイト](/reference/events)で確認できます。
+* Bolt では、アプリにアタッチされたクライアントから [Web API メソッドを呼び出す](/tools/bolt-python/concepts/web-api)ことができます。API サイトに [220 以上のメソッド](/reference/methods)を一覧しています。
+* [API サイト](/authentication/tokens)でほかのタイプのトークンを確認してみてください。アプリで実行したいアクションによって、異なるトークンが必要になる場合があります。

+# ワークフローステップの概要
+
+（アプリによる）ワークフローステップでは、処理をアプリ側で行うカスタムのワークフローステップを提供することができます。ユーザーは[ワークフロービルダー](/workflows/workflow-builder)を使ってこれらのステップをワークフローに追加できます。
+
+ワークフローステップは、次の 3 つのユーザーイベントで構成されます。
+
+- ワークフローステップをワークフローに追加・変更する
+- ワークフロー内のステップの設定内容を更新する
+- エンドユーザーがそのステップを実行する
+
+ワークフローステップを機能させるためには、これら 3 つのイベントすべてに対応する必要があります。
+
+## ステップの定義
+
+ワークフローステップの作成には、Bolt が提供する `WorkflowStep` クラスを利用します。
+
+ステップの `callback_id` と設定オブジェクトを指定して、`WorkflowStep` の新しいインスタンスを作成します。
+
+設定オブジェクトは、`edit`、`save`、`execute` という 3 つのキーを持ちます。それぞれのキーは、単一のコールバック、またはコールバックのリストである必要があります。すべてのコールバックは、ワークフローステップのイベントに関する情報を保持する `step` オブジェクトにアクセスできます。
+
+`WorkflowStep` のインスタンスを作成したら、それを`app.step()` メソッドに渡します。これによって、アプリがワークフローステップのイベントをリッスンし、設定オブジェクトで指定されたコールバックを使ってそれに応答できるようになります。
+
+また、デコレーターとして利用できる `WorkflowStepBuilder` クラスを使ってワークフローステップを定義することもできます。 詳細は、[こちらのドキュメント](https://docs.slack.dev/tools/bolt-python/reference/workflows/step/step.html#slack_bolt.workflows.step.step.WorkflowStepBuilder)のコード例などを参考にしてください。
+
+指定可能な引数の一覧はモジュールドキュメントを参考にしてください（[共通](https://docs.slack.dev/tools/bolt-python/reference/kwargs_injection/args.html) / [ステップ用](https://docs.slack.dev/tools/bolt-python/reference/workflows/step/utilities/index.html)）
+
+```python
+import os
+from slack_bolt import App
+from slack_bolt.workflows.step import WorkflowStep
+
+# いつも通りBolt アプリを起動する
+app = App(
+    token=os.environ.get("SLACK_BOT_TOKEN"),
+    signing_secret=os.environ.get("SLACK_SIGNING_SECRET")
+)
+
+def edit(ack, step, configure):
+    pass
+
+def save(ack, view, update):
+    pass
+
+def execute(step, complete, fail):
+    pass
+
+# WorkflowStep の新しいインスタンスを作成する
+ws = WorkflowStep(
+    callback_id="add_task",
+    edit=edit,
+    save=save,
+    execute=execute,
+)
+# ワークフローステップを渡してリスナーを設定する
+app.step(ws)
+```
+
+## ステップの追加・編集
+
+作成したワークフローステップがワークフローに追加またはその設定を変更されるタイミングで、`workflow_step_edit` イベントがアプリに送信されます。このイベントがアプリに届くと、`WorkflowStep` で設定した `edit` コールバックが実行されます。
+
+ステップの追加と編集のどちらが行われるときも、ワークフローステップの設定モーダルをビルダーに送信する必要があります。このモーダルは、そのステップ独自の設定を選択するための場所です。通常のモーダルより制限が強く、例えば `title`、`submit`、`close` のプロパティを含めることができません。設定モーダルの `callback_id` は、デフォルトではワークフローステップと同じものになります。
+
+`edit` コールバック内で `configure()` ユーティリティを使用すると、対応する `blocks` 引数にビューのblocks 部分だけを渡して、ステップの設定モーダルを簡単に表示させることができます。必要な入力内容が揃うまで設定の保存を無効にするには、`True` の値をセットした `submit_disabled` を渡します。
+
+指定可能な引数の一覧はモジュールドキュメントを参考にしてください（[共通](https://docs.slack.dev/tools/bolt-python/reference/kwargs_injection/args.html) / [ステップ用](https://docs.slack.dev/tools/bolt-python/reference/workflows/step/utilities/index.html)）
+
+```python
+def edit(ack, step, configure):
+    ack()
+
+    blocks = [
+        {
+            "type": "input",
+            "block_id": "task_name_input",
+            "element": {
+                "type": "plain_text_input",
+                "action_id": "name",
+                "placeholder": {"type": "plain_text", "text":"Add a task name"},
+            },
+            "label": {"type": "plain_text", "text":"Task name"},
+        },
+        {
+            "type": "input",
+            "block_id": "task_description_input",
+            "element": {
+                "type": "plain_text_input",
+                "action_id": "description",
+                "placeholder": {"type": "plain_text", "text":"Add a task description"},
+            },
+            "label": {"type": "plain_text", "text":"Task description"},
+        },
+    ]
+    configure(blocks=blocks)
+
+ws = WorkflowStep(
+    callback_id="add_task",
+    edit=edit,
+    save=save,
+    execute=execute,
+)
+app.step(ws)
+```
+
+##  ステップの設定の保存
+
+設定モーダルを開いた後、アプリは `view_submission` イベントをリッスンします。このイベントがアプリに届くと、`WorkflowStep` で設定した `save` コールバックが実行されます。
+
+`save` コールバック内では、`update()` メソッドを使って、ワークフローに追加されたステップの設定を保存することができます。このメソッドには次の引数を指定します。
+
+- `inputs` : ユーザーがワークフローステップを実行したときにアプリが受け取る予定のデータを表す辞書型の値です。
+- `outputs` : ワークフローステップの完了時にアプリが出力するデータが設定されたオブジェクトのリストです。この outputs は、ワークフローの後続のステップで利用することができます。
+- `step_name` : ステップのデフォルトの名前をオーバーライドします。
+- `step_image_url` : ステップのデフォルトの画像をオーバーライドします。
+
+指定可能な引数の一覧はモジュールドキュメントを参考にしてください（[共通](https://docs.slack.dev/tools/bolt-python/reference/kwargs_injection/args.html) / [ステップ用](https://docs.slack.dev/tools/bolt-python/reference/workflows/step/utilities/index.html)）
+
+```python
+def save(ack, view, update):
+    ack()
+
+    values = view["state"]["values"]
+    task_name = values["task_name_input"]["name"]
+    task_description = values["task_description_input"]["description"]
+
+    inputs = {
+        "task_name": {"value": task_name["value"]},
+        "task_description": {"value": task_description["value"]}
+    }
+    outputs = [
+        {
+            "type": "text",
+            "name": "task_name",
+            "label":"Task name",
+        },
+        {
+            "type": "text",
+            "name": "task_description",
+            "label":"Task description",
+        }
+    ]
+    update(inputs=inputs, outputs=outputs)
+
+ws = WorkflowStep(
+    callback_id="add_task",
+    edit=edit,
+    save=save,
+    execute=execute,
+)
+app.step(ws)
+```
+
+## ステップの実行
+
+エンドユーザーがワークフローステップを実行すると、アプリに `workflow_step_execute` イベントが送信されます。このイベントがアプリに届くと、`WorkflowStep` で設定した `execute` コールバックが実行されます。
+
+`save` コールバックで取り出した `inputs` を使って、サードパーティの API を呼び出す、情報をデータベースに保存する、ユーザーのホームタブを更新するといった処理を実行することができます。また、ワークフローの後続のステップで利用する出力値を `outputs` オブジェクトに設定します。
+
+`execute` コールバック内では、`complete()` を呼び出してステップの実行が成功したことを示すか、`fail()` を呼び出してステップの実行が失敗したことを示す必要があります。
+
+指定可能な引数の一覧はモジュールドキュメントを参考にしてください（[共通](https://docs.slack.dev/tools/bolt-python/reference/kwargs_injection/args.html) / [ステップ用](https://docs.slack.dev/tools/bolt-python/reference/workflows/step/utilities/index.html)）
+
+```python
+def execute(step, complete, fail):
+    inputs = step["inputs"]
+    # すべての処理が成功した場合
+    outputs = {
+        "task_name": inputs["task_name"]["value"],
+        "task_description": inputs["task_description"]["value"],
+    }
+    complete(outputs=outputs)
+
+    # 失敗した処理がある場合
+    error = {"message":"Just testing step failure!"}
+    fail(error=error)
+
+ws = WorkflowStep(
+    callback_id="add_task",
+    edit=edit,
+    save=save,
+    execute=execute,
+)
+app.step(ws)
+```

-                We strongly recommend using RequestVerification for better security.
-                If you have a proxy that verifies request signature in front of the Bolt app,
-                it&#39;s totally fine to disable RequestVerification to avoid duplication of work.

-### Creating an async app
-
-If you&#39;d prefer to build your app with [asyncio](https://docs.python.org/3/library/asyncio.html), you can import the [AIOHTTP](https://docs.aiohttp.org/en/stable/) library and call the `AsyncApp` constructor. Within async apps, you can use the async/await pattern.
-
-```bash
-# Python 3.6+ required
-python -m venv .venv
-source .venv/bin/activate
-
-pip install -U pip
-# aiohttp is required
-pip install slack_bolt aiohttp
-```
-
-In async apps, all middleware/listeners must be async functions. When calling utility methods (like `ack` and `say`) within these functions, it&#39;s required to use the `await` keyword.
-
-```python
-# Import the async app instead of the regular one
-from slack_bolt.async_app import AsyncApp
-
-app = AsyncApp()
-
-@app.event(&#34;app_mention&#34;)
-async def event_test(body, say, logger):
-    logger.info(body)
-    await say(&#34;What&#39;s up?&#34;)
-
-@app.command(&#34;/hello-bolt-python&#34;)
-async def command(ack, body, respond):
-    await ack()
-    await respond(f&#34;Hi &lt;@{body[&#39;user_id&#39;]}&gt;!&#34;)
-
-if __name__ == &#34;__main__&#34;:
-    app.start(3000)
-```
-
-If you want to use another async Web framework (e.g., Sanic, FastAPI, Starlette), take a look at the built-in adapters and their examples.
