Example: Client Feedback

example-client-feedback page anchor

In this Flow, a client will be notified that their call will be recorded. The call recording will then proceed and, if successful, will ask the client what their experience was like. After the client stops talking, the recording will be stopped. The specified Recording Status Callback URL for the Widget will handle all events of the recording.
