Feature Overview

This callback allows you to view the deletion status of a topic in real time on the application backend. Specifically, you can view the real-time log of the topic deletion or sync the information to other systems.

Notes

To enable this callback, you must configure the URL. This callback and the callback after group disbanding use the same switch. For detailed directions, see Webhook 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.
You need to enable the topic feature in the console before using it.

Callback Triggering Scenarios

The application user deletes a topic on the client.
The application admin deletes a topic through the RESTful API.
