After a Official Account Is Full

Feature Overview

This webhook allows the app backend to monitor in real-time if the subscription count for the Official Account has reached its limit, ensuring users can subscribe.

Notes

To enable the webhook, you must configure the Webhook URL and toggle on the corresponding protocol. For more information on the configuration method, see Webhook Configuration.
During this webhook, 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 additional safety-related concerns, please refer to the Webhook Overview: Security Considerations document.
