After a Group Message Is Sent

Feature Overview
This webhook event is used by the app backend to check users' group messages in real time. The app backend can be notified when a group message is sent successfully and can synchronize the data as required.
Limits
To enable this webhook, you must configure a callback URL and enable the corresponding switch for this webhook. 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.
