We are developing an integration with eBay for shipping purposes. Our platform takes care of labeling by communicating with a set of carriers. In general, we import some of the orders from eBay through the Trading API but we also want to synchronize the shipping statuses back to eBay so that our customers (sellers) can observe status updates there as well.
So far we are able to set an order as dispatched (through a CompleteSale call). Is there a way to set an order as "In transit", "out for delivery" and "delivered" through the API?
I have looked in the documentation and could not find anything regarding shipping statuses. Is there functionality available for setting the shipping status explicitly through the API?
