After Official Account Is Subscribed

Feature Overview

After subscribing to the Official Account, the app backend can use this webhook to view the subscription messages in real-time, including: Notification to the app backend when a member subscribes to the Official Account, allowing the app to perform necessary data synchronization.

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.
