Callback after Call Ends

Feature Description
The App backend can monitor in real-time the dynamics of call ending through this callback. Five seconds after call termination, call details can be queried through the call record inquiry API.
Must-Knows
To enable the callback, you must configure the callback URL through the REST API and turn on the switch corresponding to this callback protocol. For the configuration method, see Set Callback Configuration.
The direction of the callback is that the Call backend initiates an HTTP POST request to the App backend.
After receiving a callback request, the App backend needs to verify whether the value of the SDKAppID parameter in the request URL is its own SDKAppID.
Callback Triggering Scenarios
Call termination.
Callback Triggering Timing
When the number of call participants is less than or equal to 1, trigger call termination and reclaim.
API Description
Sample Request URL
In the following example, the callback URL configured for the App is https://www.example.com.
Example:
