Callback After Recalling Group Messages

Overview

This webhook event is used by the app backend to check the recalls of group messages in real time.

Notes

To enable this webhook, you must configure a webhook URL and toggle on the corresponding protocol. For more information on the configuration method, see Webhook Configuration.
During this webhook event, 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.
