Feature Overview
This callback allows you to view a group member's request to invite another user to join the group on the app backend in real time. You can directly block such request on the app backend.
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 IM 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 request to invite another user to join the group on the client.
The app admin adds a user to a group through the RESTful API.
Callback Triggering Timing
This callback will be triggered before the IM backend adds the target user to the group (or after the friendship verification is passed, if relationship chain hosting is involved and friendship verification is configured in IM for the app).
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

Blocking certain members from joining the group
The app backend blocks certain users identified in the requests from being invited to the group. The identifiers of such users are returned in
RefusedMembers_Account.{"ActionStatus": "OK","ErrorInfo": "","ErrorCode": 0,"RefusedMembers_Account": [ // List of users who refused to join the group"jared"]}
Response fields
