# Service Usage API . services

## Instance Methods

Enable multiple services on a project. The operation is atomic: if enabling any service fails, then the entire batch fails, and no state changes occur. To enable a single service, use the `EnableService` method instead.

Returns the service configurations and enabled states for a given list of services.

Close httplib2 connections.

Disable a service so that it can no longer be used with a project. This prevents unintended usage that may cause unexpected billing charges or security leaks. It is not valid to call the disable method on a service that is not currently enabled. Callers will receive a `FAILED_PRECONDITION` status if the target service is not currently enabled.

Enable a service so that it can be used with a project.

Returns the service configuration and enabled state for a given service.

List all services available to the specified project, and the current state of those services with respect to the project. The list includes all public services, all services for which the calling user has the `servicemanagement.services.bind` permission, and all services that have already been enabled on the project. The list can be filtered to only include services in a specific state, for example to only include services enabled on the project. WARNING: If you need to query enabled services frequently or across an organization, you should use [Cloud Asset Inventory API](https://cloud.google.com/asset-inventory/docs/apis), which provides higher throughput and richer filtering capability.

### Method Details

`batchEnable(parent, body=None, x__xgafv=None)`

    Enable multiple services on a project. The operation is atomic: if enabling any service fails, then the entire batch fails, and no state changes occur. To enable a single service, use the `EnableService` method instead.

    Args:
      parent: string, Parent to enable services on. An example name would be: `projects/123` where `123` is the project number. The `BatchEnableServices` method currently only supports projects. (required)
      body: object, The request body.
        The object takes the form of:

    { # Request message for the `BatchEnableServices` method.
        "serviceIds": [ # The identifiers of the services to enable on the project. A valid identifier would be: serviceusage.googleapis.com Enabling services requires that each service is public or is shared with the user enabling the service. A single request can enable a maximum of 20 services at a time. If more than 20 services are specified, the request will fail, and no state changes will occur.
          "A String",
        ],
      }

      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:
      An object of the form:

        { # This resource represents a long-running operation that is the result of a network API call.
        "done": True or False, # If the value is `false`, it means the operation is still in progress. If `true`, the operation is completed, and either `error` or `response` is available.
        "error": { # The `Status` type defines a logical error model that is suitable for different programming environments, including REST APIs and RPC APIs. It is used by [gRPC](https://github.com/grpc). Each `Status` message contains three pieces of data: error code, error message, and error details. You can find out more about this error model and how to work with it in the [API Design Guide](https://cloud.google.com/apis/design/errors). # The error result of the operation in case of failure or cancellation.

        "response": { # The normal response of the operation in case of success. If the original method returns no data on success, such as `Delete`, the response is `google.protobuf.Empty`. If the original method is standard `Get`/`Create`/`Update`, the response should be the resource. For other methods, the response should have the type `XxxResponse`, where `Xxx` is the original method name. For example, if the original method name is `TakeSnapshot()`, the inferred response type is `TakeSnapshotResponse`.
          "a_key": "", # Properties of the object. Contains field @type with type URL.
        },
        "metadata": { # Service-specific metadata associated with the operation. It typically contains progress information and common metadata such as create time.

        },
      }

`batchGet(parent, names=None, x__xgafv=None)`

    Returns the service configurations and enabled states for a given list of services.

    Args:
      parent: string, Parent to retrieve services from. If this is set, the parent of all of the services specified in `names` must match this field. An example name would be: `projects/123` where `123` is the project number. The `BatchGetServices` method currently only supports projects. (required)
      names: string, Names of the services to retrieve. An example name would be: `projects/123/services/serviceusage.googleapis.com` where `123` is the project number. A single request can get a maximum of 30 services at a time. (repeated)

        Allowed values
          1 - v1 error format

Interfaces are also described as "protocol buffer services" in some contexts, such as by the "service" keyword in a .proto file, but they are different from API Services, which represent a concrete implementation of an interface as opposed to simply a description of methods and bindings. They are also sometimes simply referred to as "APIs" in other contexts, such as the name of this message itself. See https://cloud.google.com/apis/design/glossary for detailed terminology.

If the field is not empty, the version in the package name will be verified to be consistent with what is provided here. The versioning schema uses [semantic versioning](http://semver.org) where the major version number indicates a breaking change and the minor version an additive, non-breaking change. Both version numbers are signals to users what to expect from different versions, and should be carefully chosen based on the product plan. The major version is also reflected in the package name of the interface, which must end in `v`, as in `google.feature.v1`. For major versions 0 and 1, the suffix can be omitted. Zero major versions must only be used for experimental, non-GA interfaces.

Any version prefix will be replaced by the version of the including interface plus the root path if specified. Example of a simple mixin: package google.acl.v1; service AccessControl { // Get the underlying ACL object. rpc GetAcl(GetAclRequest) returns (Acl) { option (google.api.http).get = "/v1/{resource=**}:getAcl"; } } package google.storage.v2; service Storage { // rpc GetAcl(GetAclRequest) returns (Acl); // Get a data record. rpc GetData(GetDataRequest) returns (Data) { option (google.api.http).get = "/v2/{resource=**}"; } } Example of a mixin configuration: apis: - name: google.storage.v2.Storage mixins: - name: google.acl.v1.AccessControl The mixin construct implies that all methods in `AccessControl` are also declared with same name and request/response types in `Storage`. A documentation generator or annotation processor will see the effective `Storage.GetAcl` method after inheriting documentation and annotations as follows: service Storage { // Get the underlying ACL object. rpc GetAcl(GetAclRequest) returns (Acl) { option (google.api.http).get = "/v2/{resource=**}:getAcl"; } ... } Note how the version in the path pattern changed from `v1` to `v2`. If the `root` field in the mixin is specified, it should be a relative path under which inherited HTTP paths are placed. Example: apis: - name: google.storage.v2.Storage mixins: - name: google.acl.v1.AccessControl root: acls This implies the following inherited HTTP annotation: service Storage { // Get the underlying ACL object. rpc GetAcl(GetAclRequest) returns (Acl) { option (google.api.http).get = "/v2/acls/{resource=**}:getAcl"; } ... }

Interfaces are also described as "protocol buffer services" in some contexts, such as by the "service" keyword in a .proto file, but they are different from API Services, which represent a concrete implementation of an interface as opposed to simply a description of methods and bindings. They are also sometimes simply referred to as "APIs" in other contexts, such as the name of this message itself. See https://cloud.google.com/apis/design/glossary for detailed terminology.

If the field is not empty, the version in the package name will be verified to be consistent with what is provided here. The versioning schema uses [semantic versioning](http://semver.org) where the major version number indicates a breaking change and the minor version an additive, non-breaking change. Both version numbers are signals to users what to expect from different versions, and should be carefully chosen based on the product plan. The major version is also reflected in the package name of the interface, which must end in `v`, as in `google.feature.v1`. For major versions 0 and 1, the suffix can be omitted. Zero major versions must only be used for experimental, non-GA interfaces.

Any version prefix will be replaced by the version of the including interface plus the root path if specified. Example of a simple mixin: package google.acl.v1; service AccessControl { // Get the underlying ACL object. rpc GetAcl(GetAclRequest) returns (Acl) { option (google.api.http).get = "/v1/{resource=**}:getAcl"; } } package google.storage.v2; service Storage { // rpc GetAcl(GetAclRequest) returns (Acl); // Get a data record. rpc GetData(GetDataRequest) returns (Data) { option (google.api.http).get = "/v2/{resource=**}"; } } Example of a mixin configuration: apis: - name: google.storage.v2.Storage mixins: - name: google.acl.v1.AccessControl The mixin construct implies that all methods in `AccessControl` are also declared with same name and request/response types in `Storage`. A documentation generator or annotation processor will see the effective `Storage.GetAcl` method after inheriting documentation and annotations as follows: service Storage { // Get the underlying ACL object. rpc GetAcl(GetAclRequest) returns (Acl) { option (google.api.http).get = "/v2/{resource=**}:getAcl"; } ... } Note how the version in the path pattern changed from `v1` to `v2`.

Example: apis: - name: google.storage.v2.Storage mixins: - name: google.acl.v1.AccessControl root: acls This implies the following inherited HTTP annotation: service Storage { // Get the underlying ACL object. rpc GetAcl(GetAclRequest) returns (Acl) { option (google.api.http).get = "/v2/acls/{resource=**}:getAcl"; } ... }

`list(parent, filter=None, pageSize=None, pageToken=None, x__xgafv=None)`

    List all services available to the specified project, and the current state of those services with respect to the project. The list includes all public services, all services for which the calling user has the `servicemanagement.services.bind` permission, and all services that have already been enabled on the project. The list can be filtered to only include services in a specific state, for example to only include services enabled on the project. WARNING: If you need to query enabled services frequently or across an organization, you should use [Cloud Asset Inventory API](https://cloud.google.com/asset-inventory/docs/apis), which provides higher throughput and richer filtering capability.

    Args:
      parent: string, Parent to search for services on. An example name would be: `projects/123` where `123` is the project number. (required)
      filter: string, Only list services that conform to the given filter. The allowed filter strings are `state:ENABLED` and `state:DISABLED`.
      pageSize: integer, Requested size of the next page of data. Requested page size cannot exceed 200. If not set, the default page size is 50.
      pageToken: string, Token identifying which result to start with, which is returned by a previous list call.
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:
      An object of the form:

They are also sometimes simply referred to as "APIs" in other contexts, such as the name of this message itself. See https://cloud.google.com/apis/design/glossary for detailed terminology.
                  "version": "A String", # A version string for this interface. If specified, must have the form `major-version.minor-version`, as in `1.10`. If the minor version is omitted, it defaults to zero. If the entire version field is empty, the major version is derived from the package name, as outlined below. If the field is not empty, the version in the package name will be verified to be consistent with what is provided here. The versioning schema uses [semantic versioning](http://semver.org) where the major version number indicates a breaking change and the minor version an additive, non-breaking change. Both version numbers are signals to users what to expect from different versions, and should be carefully chosen based on the product plan. The major version is also reflected in the package name of the interface, which must end in `v`, as in `google.feature.v1`. For major versions 0 and 1, the suffix can be omitted. Zero major versions must only be used for experimental, non-GA interfaces.

Any version prefix will be replaced by the version of the including interface plus the root path if specified. Example of a simple mixin: package google.acl.v1; service AccessControl { // Get the underlying ACL object. rpc GetAcl(GetAclRequest) returns (Acl) { option (google.api.http).get = "/v1/{resource=**}:getAcl"; } } package google.storage.v2; service Storage { // rpc GetAcl(GetAclRequest) returns (Acl); // Get a data record. rpc GetData(GetDataRequest) returns (Data) { option (google.api.http).get = "/v2/{resource=**}"; } } Example of a mixin configuration: apis: - name: google.storage.v2.Storage mixins: - name: google.acl.v1.AccessControl The mixin construct implies that all methods in `AccessControl` are also declared with same name and request/response types in `Storage`. A documentation generator or annotation processor will see the effective `Storage.GetAcl` method after inheriting documentation and annotations as follows: service Storage { // Get the underlying ACL object. rpc GetAcl(GetAclRequest) returns (Acl) { option (google.api.http).get = "/v2/{resource=**}:getAcl"; } ... } Note how the version in the path pattern changed from `v1` to `v2`. If the `root` field in the mixin is specified, it should be a relative path under which inherited HTTP paths are placed. Example: apis: - name: google.storage.v2.Storage mixins: - name: google.acl.v1.AccessControl root: acls This implies the following inherited HTTP annotation: service Storage { // Get the underlying ACL object. rpc GetAcl(GetAclRequest) returns (Acl) { option (google.api.http).get = "/v2/acls/{resource=**}:getAcl"; } ... }
