Callback for Room Member Status Change

Feature Overview

The app backend can view users' online and offline status changes in the room in real time through this callback.

Notes

To enable this callback, you must configure the callback URL and toggle on the corresponding protocol. For more information on the configuration method, see Third party callback configuration documentation.
During this callback, the Live 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 consistent with its own SDKAppID.

Scenarios that may trigger this callback

App users successfully create a room through the client
App administrators successfully create a room via the REST API

Callback Trigger Time

After the room is created successfully.
