Seller wants to use a Other carrier to handle seller fulfilled orders. That is, a carrier that is not USPS, UPS, FedEx.
We can mark the orders as shipped and push the tracking information using SP-API
POST /orders/v0/orders/{orderId}/shipment
However as this is not a Amazon listed carrier the tracking information is not automatically updated by Amazon. On the buyers side the order shows up as running late even after it is delivered by the courier.
How can the carrier or seller push the delivery status for the order? Is there a operation in SP-API to update the tracking status to delivered ? I was unable to see a way in the Seller Central to achieve this even using the UI.
How does Amazon automatically update the status of order for tracking with carriers like USPS, UPS, FedEx ? Do they pull the tracking information from these carriers or do the carriers somehow push status to Amazon ?
We want to not update the status and complete the order and prevent the buyer from logging a refund request.
