---

This example appears wrapped in the standard event wrapper used by all events delivered on the Events API.

    "token": "one-long-verification-token",

    "api_app_id": "A0PNCHHK2",
    "event": {
        "type": "message",
        "channel": "G024BE91L",
        "user": "U2147483697",
        "text": "Let's make a pact.",

    },

}

The semantics for this message event type are similar to the core message event sent through the RTM API. Messages often include many more fields than those shown above.

Differentiate multi-party direct messages from other message.* events by looking for the event's channel_type field set to "mpim".
