トピック情報変更コールバック

Feature Overview

This callback allows you to view the changes in the topic profile (topic name, topic introduction, topic notice, and topic profile photo) in real time on the application backend. Specifically, you can view the real-time log of the changed topic profile or sync the information to other systems.

Notes

To enable this callback, you must configure the URL. This callback and the callback after group profile modification use the same switch. For detailed directions, see Webhook Configuration.
During this callback, the IM 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

Callback triggering content

The topic profile includes the basic topic profile and custom topic field. Currently, this callback may be triggered by a change in the topic name, topic introduction, topic notice, or topic profile photo URL, and will not be triggered by a change in other basic topic profile.

Callback triggering methods

The app user modifies the topic profile on the client.
The app admin modifies the topic profile through the RESTful API.

Callback Triggering Timing

It will be triggered after the topic profile is changed.
