The Amazon Pay Delivery Tracker API lets you provide shipment tracking information to Amazon Pay so that Amazon Pay can notify buyers on Alexa when shipments are delivered. This API is channel-agnostic. That means that anywhere you use Amazon Pay, you can use the Delivery Tracker API. https://developer.amazon.com/docs/amazon-pay-onetime/delivery-notifications.html?ld=emexukapa-li-spad-uk-xxx

Since Amazon Pay needs updating anyway it would be very nice to also add the delivery tracker.
