  title: Agent Messages API
  description: 'This document refers to Symphony API calls to send and receive messages

    and content. They need the on-premise Agent installed to perform

    decryption/encryption of content.


    - sessionToken and keyManagerToken can be obtained by calling the

    authenticationAPI on the symphony back end and the key manager

    respectively. Refer to the methods described in authenticatorAPI.yaml.

    - Actions are defined to be atomic, ie will succeed in their entirety

    or fail and have changed nothing.

    - If it returns a 40X status then it will have sent no message to any

    stream even if a request to some subset of the requested streams

    would have succeeded.

    - If this contract cannot be met for any reason then this is an error

    and the response code will be 50X.

    - MessageML is a markup language for messages. See reference here:

    https://rest-api.symphony.com/docs/messagemlv2

    - **Real Time Events**: The following events are returned when reading

    from a real time messages and events stream ("datafeed"). These

    events will be returned for datafeeds created with the v5 endpoints.

    To know more about the endpoints, refer to Create Messages/Events

    Stream and Read Messages/Events Stream. Unless otherwise specified,

    all events were added in 1.46.

      summary: Import messages from other systems into Symphony.
      description: 'Sends a message to be imported into the system.

        Allows you to override the timestamp and author of the message with your desired values.

        The requesting user must have the Content Management role.

        The user that the message is intended to have come from must also be present in the conversation.

        The intended message timestamp must be a valid time from the past. It cannot be a future timestamp.

        Optionally the original message ID can be specified to identify the imported message for the purpose of repeat imports.

      summary: Post a message to multiple existing streams.
      description: 'Post a new message to the given list of streams. The stream can be a chatroom,

        an IM or a multiparty IM.


        You may include an attachment on the message.


        The message can be provided as MessageMLV2 or PresentationML. Both formats support Freemarker templates.


        The optional parameter "data" can be used to provide a JSON payload containing entity data.

        If the message contains explicit references to entity data (in "data-entity-id" element attributes),

        this parameter is required.


        If the message is in MessageML and fails schema validation a client error results


        This endpoint is idempotent, it means that a 200 response will be returned even if the message has not been

        delivered to some streams. Check the `errors` map from the response in order to see on which stream(s) the

        message has not been delivered.


        The maximum number of streams where the message can be sent is limitted to 100.


        Regarding authentication, you must either use the sessionToken which was created for delegated app access

        or both the sessionToken and keyManagerToken together.
