This is my first ebay integration ...
I have enabled the AuctionCheckoutComplete notification for my sandbox test seller account. When using the Sandbox UI, I am able to use a sandbox buyer account to purchase items from my buyer. This action successfully triggers the notification, and I receive it into my API.
What I can't test (mainly due to issues using the Sandbox UI) is what happens in a scenario where a buyer purchases multiple items (a basket of things). Do I get a notification per item in my basket, or do I get a single notification containing multiple items?
The GetItemTransactionResponse XML schema is confusing (to me). I can see a single Item element, but then there are multiple Transaction elements. Can anyone help me here? One way of resolving this is to enable my live seller account - and do my testing there - but I'm reluctant.
Obviously, if we had a fully functional Sandbox environment, this would not be a problem. I am making a big assumption that it's an issue with the Sandbox and not my local setup :)
