Overview

This webhook event is used by the app backend to check users' group creation requests in real time. The app backend can also reject the requests.

Notes

To enable this webhook, you must configure a webhook URL and toggle on the corresponding protocol. For more information on the configuration method, see Webhook Configuration.
During this webhook event, the Chat backend initiates an HTTP POST request to the app backend.
After receiving the webhook 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 Webhook Overview.

Webhook Triggering Scenarios

The app user creates a group on the client.
The app admin creates a group through the RESTful API.

Webhook Triggering Timing

It will be triggered before the Chat backend creates a group.
