I need to mark an item as paid for on ebay when a payment is maid through an external payment page (not PayPal). I have been looking at CompleteSale, but this looks like I need a transactionID but how do I get a transactionID of a transaction that hasn't occured on ebay? Maybe im going about this the wrong way.
Anyone know how to mark an item as paid through ebay API? I have the item id, sellers ID and the payer's ebay id.
