                        Optional. A publicly accessible HTTPS URL. When the task
                        status changes (processing / success / failed),
                        GoEnhance sends a POST request to this URL. The request
                        body is identical to the response of GET
                        /api/v1/jobs/detail. If your server does not respond
                        with HTTP 200, the notification is retried up to 3
                        times, with a 3-second timeout per attempt.
