Webhook for Exceptions When Group Messages Are Sent

Feature Overview
This callback allows you to monitor the exceptions on the application backend when group messages are sent, including:
The message sent contains an incorrect parameter (for example, the group ID does not exist).
The message sending frequency exceeds the limit.
The message sent is found to be non-compliant after content filtering.
The sender is muted.
Notes
To enable this callback, you must configure a callback URL and enable the corresponding switch for this callback. For more information on the configuration method, see Callback Configuration.
During this callback, the Chat backend initiates an HTTP POST request to the app backend.
After receiving the callback request, the app backend must check whether the SDKAppID contained in the request URL is the SDKAppID of the app.
For more security considerations, see the Security Considerations section in Third-Party Callback Overview.
Callback Triggering Scenarios
An app user sends a group message on the client.
The app admin sends a group message via a RESTful API call.
Callback Triggering Timing
It will be triggered after the Chat backend failed to deliver the group message to group members.
