Callback Overview

To facilitate control over the app's features, LiveKit offers callback capabilities.

Feature Overview

Users can configure a callback to a specified URL via REST API. When the executed CallbackCommand is on the configuration list, it will trigger the callback.

Notes

Only one callback can be set per sdkAppId.
Ensure that the callback URL is accessible.

Callback Protocol

Third-party callbacks are based on HTTP/HTTPS protocols. The app backend must provide a callback URL to the live platform, and Instant Chat uses a POST request to initiate a callback to the app backend. When initiating a callback, Chat adds the following parameters to the URL provided by the app:
Parameter
Meaning
SdkAppId
SDKAppId assigned by the Chat console when an app is created
CallbackCommand
Callback Command Word
contenttype
Optional, usually set to JSON
ClientIP
Client IP address
OptPlatform
Client Platform, corresponding to different Platform Types, possible values include: RESTAPI (sending requests using REST API), Web (sending requests using Web SDK), Android, iOS, Windows, Mac, iPad, Unknown (sending requests using an unknown type of device)
