Callback After Sending an Official Account Message

Feature Overview

The app backend can use this webhook to check the broadcast messages of the official account in real time, including notifications that the app backend has successfully sent a official account message, allowing the app to perform the necessary data synchronization.

Notes

To enable the webhook, you must configure the Webhook URL and enable the corresponding switch for this webhook. 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, please refer to the Webhook Overview: Security Considerations document.

Webhook Triggering Scenarios

An app user sends a Official Account Message via the client.
The app administrator sends a Official Account Message via RESTful APIs.

Webhook Triggering Timing

The webhook is triggered after the Chat backend delivers the official account message to subscribers.
