### Method Details

`analyzeContent(participant, body=None, x__xgafv=None)`

    Adds a text (chat, for example), or audio (phone recording, for example) message from a participant into the conversation. Note: Always use agent versions for production traffic sent to virtual agents. See [Versions and environments](https://cloud.google.com/dialogflow/es/docs/agents-versions).

    Args:
      participant: string, Required. The name of the participant this text comes from. Format: `projects//locations//conversations//participants/`. (required)
      body: object, The request body.
        The object takes the form of:

    { # The request message for Participants.AnalyzeContent.
      "assistQueryParams": { # Represents the parameters of human assist query. # Parameters for a human assist query.
        "documentsMetadataFilters": { # Key-value filters on the metadata of documents returned by article suggestion. If specified, article suggestion only returns suggested documents that match all filters in their Document.metadata. Multiple values for a metadata key should be concatenated by comma. For example, filters to match all documents that have 'US' or 'CA' in their market metadata values and 'agent' in their user metadata values will be ``` documents_metadata_filters { key: "market" value: "US,CA" } documents_metadata_filters { key: "user" value: "agent" } ```
          "a_key": "A String",
        },
      },
      "eventInput": { # Events allow for matching intents by event name instead of the natural language input. For instance, input `` can trigger a personalized welcome response. The parameter `name` may be used by the agent in the response: `"Hello #welcome_event.name! What can I do for you today?"`. # An input event to send to Dialogflow.
        "languageCode": "A String", # Required. The language of this query. See [Language Support](https://cloud.google.com/dialogflow/docs/reference/language) for a list of the currently supported language codes. Note that queries in the same session do not necessarily need to specify the same language. This field is ignored when used in the context of a WebhookResponse.followup_event_input field, because the language was already defined in the originating detect intent request.
        "name": "A String", # Required. The unique identifier of the event.
        "parameters": { # The collection of parameters associated with the event. Depending on your protocol or client library language, this is a map, associative array, symbol table, dictionary, or JSON object composed of a collection of (MapKey, MapValue) pairs: - MapKey type: string - MapKey value: parameter name - MapValue type: - If parameter's entity type is a composite entity: map - Else: depending on parameter value type, could be one of string, number, boolean, null, list or map - MapValue value: - If parameter's entity type is a composite entity: map from composite entity property names to property values - Else: parameter value
          "a_key": "", # Properties of the object.
        },
      },
      "messageSendTime": "A String", # Optional. The send time of the message from end user or human agent's perspective. It is used for identifying the same message under one participant. Given two messages under the same participant: - If send time are different regardless of whether the content of the messages are exactly the same, the conversation will regard them as two distinct messages sent by the participant. - If send time is the same regardless of whether the content of the messages are exactly the same, the conversation will regard them as same message, and ignore the message received later. If the value is not provided, a new request will always be regarded as a new message without any de-duplication.
      "queryParams": { # Represents the parameters of the conversational query. # Parameters for a Dialogflow virtual-agent query.
        "contexts": [ # The collection of contexts to be activated before this query is executed.
          { # Dialogflow contexts are similar to natural language context. If a person says to you "they are orange", you need context in order to understand what "they" is referring to. Similarly, for Dialogflow to handle an end-user expression like that, it needs to be provided with context in order to correctly match an intent. Using contexts, you can control the flow of a conversation. You can configure contexts for an intent by setting input and output contexts, which are identified by string names. When an intent is matched, any configured output contexts for that intent become active. While any contexts are active, Dialogflow is more likely to match intents that are configured with input contexts that correspond to the currently active contexts. For more information about context, see the [Contexts guide](https://cloud.google.com/dialogflow/docs/contexts-overview).
            "lifespanCount": 42, # Optional. The number of conversational query requests after which the context expires. The default is `0`. If set to `0`, the context expires immediately. Contexts expire automatically after 20 minutes if there are no matching queries.

If `Environment ID` is not specified, we assume default 'draft' environment. If `User ID` is not specified, we assume default '-' user. The following context names are reserved for internal use by Dialogflow. You should not use these contexts or create contexts with these names: * `__system_counters__` * `*_id_dialog_context` * `*_dialog_params_size`

Similarly, for Dialogflow to handle an end-user expression like that, it needs to be provided with context in order to correctly match an intent. Using contexts, you can control the flow of a conversation. You can configure contexts for an intent by setting input and output contexts, which are identified by string names. When an intent is matched, any configured output contexts for that intent become active. While any contexts are active, Dialogflow is more likely to match intents that are configured with input contexts that correspond to the currently active contexts.

Similarly, for Dialogflow to handle an end-user expression like that, it needs to be provided with context in order to correctly match an intent. Using contexts, you can control the flow of a conversation. You can configure contexts for an intent by setting input and output contexts, which are identified by string names. When an intent is matched, any configured output contexts for that intent become active. While any contexts are active, Dialogflow is more likely to match intents that are configured with input contexts that correspond to the currently active contexts. For more information about context, see the [Contexts guide](https://cloud.google.com/dialogflow/docs/contexts-overview).

Similarly, for Dialogflow to handle an end-user expression like that, it needs to be provided with context in order to correctly match an intent. Using contexts, you can control the flow of a conversation. You can configure contexts for an intent by setting input and output contexts, which are identified by string names. When an intent is matched, any configured output contexts for that intent become active. While any contexts are active, Dialogflow is more likely to match intents that are configured with input contexts that correspond to the currently active contexts.

If the training phrase does not need to be annotated with parameters, you just need a single part with only the Part.text field set. If you want to annotate the training phrase, you must create multiple parts, where the fields of each part are populated in one of two ways: - `Part.text` is set to a part of the phrase that has no parameters. - `Part.text` is set to a part of the phrase that you want to annotate, and the `entity_type`, `alias`, and `user_defined` fields are all set.

Similarly, for Dialogflow to handle an end-user expression like that, it needs to be provided with context in order to correctly match an intent. Using contexts, you can control the flow of a conversation. You can configure contexts for an intent by setting input and output contexts, which are identified by string names. When an intent is matched, any configured output contexts for that intent become active. While any contexts are active, Dialogflow is more likely to match intents that are configured with input contexts that correspond to the currently active contexts. For more information about context, see the [Contexts guide](https://cloud.google.com/dialogflow/docs/contexts-overview).
