Feature Overview
This callback allows you to view users' group join requests in real time on the app backend. You can block such requests.
Notes
To enable this callback, you must configure a callback URL and toggle on the corresponding protocol. For more information on the configuration method, see Callback Configuration.
During this callback, the Chat 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 the SDKAppID of the app.
For more security considerations, see the Security Considerations section in Third-Party Callback Overview.
Callback Triggering Scenarios
An app user sends a group join request on the client.
Callback Triggering Timing
It will be triggered before the Chat backend adds the user sending the group join request to the group (or before the admin is notified if admin approval is required).
API Calling Description
Sample request URL
In the following sample, the callback URL configured in the app is https://www.example.com.
Example:
https://www.example.com?SdkAppid=$SDKAppID&CallbackCommand=$CallbackCommand&contenttype=json&ClientIP=$ClientIP&OptPlatform=$OptPlatform
