我能够使用 PlaceOfferRequest (XML) 提供报价。我应该怎么做才能完成购买并将送货地址更新到他/她应该运送物品的地方?
我正在使用 XML 来发布请求。
While I can't find any official resource stating that completing purchases isn't possible, I'm 99% sure that its simply not possible. All you can do is redirect the user to the payments page, using this template for the URL:
http://payments.${DOMAIN}/ws/eBayISAPI.dll?CheckoutProcessor&item=${Item.ItemID}&transactionId=${TransactionID}
Where DOMAIN could be, for example, "sandbox.ebay.de" or just "ebay.com".
