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 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 group join request on the client.
Callback Triggering Timing
It will be triggered before the IM 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

Sample response

The group join request is not allowed to be further processed. The user cannot join the group, and the error code
10016 is returned to the caller.{"ActionStatus": "OK","ErrorInfo": "","ErrorCode": 1 // It indicates to reject the group join request.}
Response fields
Field | Type | Required | Description |
ActionStatus | String | Yes | Request result. OK: Successful; FAIL: Failed |
ErrorCode | Integer | Yes | Error code. 0 indicates to allow further processing; 1 indicates to reject the request. If you want to use the specified error code to reject a group join request, you need to pass in ErrorCode and ErrorInfo to the client, with ErrorCode in the range of [10100, 10200]. If a group join request requires admin approval, admin approval is still required even if 0 is returned in the callback. |
