      description: |-
        This endpoint is used to send a message event to a room. Message events
        allow access to historical events and pagination, making them suited
        for "once-off" activity in a room.

        The body of the request should be the content object of the event; the
        fields in this object will vary depending on the type of event. See
        `Room Events`_ for the m. event specification.

      description: |-
        This endpoint can be used to send a message event to a room; however
        the lack of a transaction ID means that it is possible to cause message
        duplication if events are resent on error, so it is preferable to use
        `PUT /_matrix/client/api/v1/rooms/{roomId}/send/{eventType}/{txnId}`_.
