After a User Is Followed

Feature Description
The App backend can view the user's newly-added attention information in real time.
Notes
To enable this webhook, you must configure the webhook URL and enable the corresponding switch for this webhook. For more information on the configuration method, see Webhook Configuration.
During this webhook, the Chat backend initiates an HTTP POST request to the app backend.
After receiving the webhook 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 Webhook Overview.
