Feature Overview

The app Backend can use this callback to view the status of group message read receipts in real-time. The app backend can perform operations such as data synchronization.

Notes

To enable the callback, you must configure a callback URL and toggle on the corresponding protocol switch. For detailed configuration methods, see Third-party Callback Configuration document.
During this callback, the Chat backend initiates an HTTP POST request to the app backend.
After the callback request is received, the app backend must check whether the SDKAppID contained in the request URL is consistent with its own SDKAppID.
For other security-related matters, please refer to the Webhook Overview - Security Considerations document.

Scenarios That May Trigger This Callback

An app user sends a read receipt message through the client.
An app user acknowledges group message read receipts through the client.
The app administrator sends a read receipt message via RESTful APIs.

Callback Trigger Time

Send a read receipt message or acknowledge a message as read.
