info:
  title: Symphony Agent Util 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.
