API Overclocking Alarm Callbacks

Feature Overview

When the request frequency of the API exceeds 80% of the threshold, the app backend is notified of the call frequency alarm information through a callback.

Notes

To enable the callback, you must configure the callback URL. For detailed configuration methods, see Webhook Configuration.
Once the callback URL is configured, an alarm callback is triggered by default if the request frequency exceeds the alarm threshold.
During this callback, the Chat backend initiates an HTTP POST request to the app backend.
After receiving the callback request, the app backend must check whether the SDKAppID contained in the request URL is consistent with its own SDKAppID.
For other security-related matters, see Webhook Overview - Security Considerations.

API Description

In the following example, the callback URL configured in the app is https://www.example.com Example:
