Message Failed

Description

The event will be triggered if a message sent through the Chat API has failed
any of the client validations. This can happen even after a successful request status
(status code 0) has been received.

The following flow outlines what happens when a message fails client validation:

1. The message is sent.
2. A response with a status of 0 is received, indicating a successful request.
3. The message reaches the client and fails client validation.
4. The failed callback is sent to the webhook, containing the unique message token
   and a string explaining the failure.

Note that failed messages will not be displayed to the recipient and no message delivered
or message seen events will be returned for it.
