Callback Before Updating User Information

Function Description​

The App business server can use this callback to receive requests from users to update their personal information. Additionally, the business server can modify and intervene in the request.

Precautions​

  • To enable the callback, it is necessary to configure the callback URL and activate the corresponding switch for this callback protocol. Configuration methods can be found in the Callback Explanation document.
  • The direction of the callback is an HTTP/HTTPS POST request initiated by OpenIMServer to the App backend.
  • After receiving the callback request, the App business server must verify whether the command parameter in the request URL is its SDKNAME parameter.
  • The APP business server must respond to this request within the timeout period.

Scenarios That May Trigger This Callback​

  • App users update their personal information through the client.
