eBay API call not working for UPC/EAN
问题 eBay's API findItemsByProduct operation would work on UPC and EAN. But unfortunately it is not working. The below HTTP GET request for example, throws an "Invalid product ID value." [error 41] http://svcs.ebay.com/services/search/FindingService/v1?SECURITY-APPNAME=MY-APP-ID-GOES-HERE&OPERATION-NAME=findItemsByProduct&SERVICE-VERSION=1.0.0&RESPONSE-DATA-FORMAT=XML&REST-PAYLOAD&productId.@type=EAN&productId=0016000275270&paginationInput.entriesPerPage=3 Note: Please replace the SECURITY-APPNAME
