I am looking into integrating with the Postmates API. Their documentation lists states that the Create a Delivery API returns a tracking url:
tracking_url: This url can be used to track the courier during the delivery
However, this does not mention what is returned. Is it the latitude and longitude? Is it an image?
What is actually returned by this URL?
It returns a web page with delivery status and a map. You can create a delivery using your sandbox key and check it out. If you want to get updates for the delivery you either need to setup a web-hook or pull delivery details using get delivery API.
