## Discussion

Forward this URL to your backend in your implementations of [`prepareAssistanceRequest(_:)`](/documentation/LiveCommunicationKit/LiveAssistanceExtension/prepareAssistanceRequest(_:)) and [`resumeRequest(_:)`](/documentation/LiveCommunicationKit/LiveAssistanceExtension/resumeRequest(_:)). When opened, this URL matches an interpreter and joins the call.

FaceTime generates this URL. Your extension only needs to pass it to your backend.
