After a Room Is Entered

Feature Overview

The App backend can view room member joining messages in real time through this callback, including: notifying the app backend of a member joining a group, allowing the app to perform necessary data synchronization.

Notes

To enable the callback, a callback URL must be configured and the switch corresponding to this callback protocol activated. For configuration methods, see Third-party Callback Configuration document.
The direction of the callback is from the Room backend to the App backend via an HTTP POST request.
After receiving the callback request, the app backend must check whether the SDKAppID contained in the request URL is consistent with its own SDKAppID.

Scenarios

App users actively join a room through the client.

Callback Trigger Time

After users successfully join a room.
