A message was sent to a channel

Facts

Works with

RTMEvents API

The posting permissions for a channel have been modified by a user.

Here's an example payload:

{
  "type": "message",
  "subtype": "channel_posting_permissions",
  "ts": "1614215651.001300",
  "user": "W01234",
  "text": "changed channel posting permissions.",
  "channel": "C01234",
  "event_ts": "1614215651.001300",
  "channel_type": "channel"
}

When an event occurs, we will send an HTTP POST request to your Request URL. The outer payload is uniform across all Events API methods, and contains fields like team_id and event. Learn more
