eBay產品API getProductDetails - 產品ID值xxxx對產品ID類型無效UPC

Question

試圖通過提交UPC獲得易趣電機零件產品的EPID &附件目錄。

下面是用於該呼叫的代碼：

$appID = 'xxxxxxxxxxxxxxxxx'; 
$siteID = 'EBAY-MOTOR';       // siteID needed in request 
$verb = 'getProductDetails';     // the call being made: 
$version = '1.4.0';       // eBay API version 

///Build the request XML request which is first part of multi-part POST 
$xmlReq = '<?xml version="1.0" encoding="utf-8"?>' . "\n"; 
$xmlReq .= '<' . $verb . 'Request xmlns="http://www.ebay.com/marketplace/marketplacecatalog/v1/services">' . "\n"; 
$xmlReq .= "<productDetailsRequest>\n"; 
$xmlReq .= "<dataset>DisplayableProductDetails</dataset>\n"; 
$xmlReq .= "<productIdentifier><UPC>" . $upc . "</UPC></productIdentifier>\n"; 
$xmlReq .= "</productDetailsRequest>\n"; 
$xmlReq .= "</" . $verb . "Request>"; 

// Create a new eBay session (defined below) 
$session = new eBaySession_Product($appID, $version, $siteID, $verb); 

$respXmlStr = $session->sendHttpRequest($xmlReq); // send multi-part request and get string XML response 
print "respXmlStr: $respXmlStr\n"; 

if(stristr($respXmlStr, 'HTTP 404') || $respXmlStr == '') 
    die('<P>Error sending request'); 

$respXmlObj = new SimpleXMLElement($respXmlStr);  // create SimpleXML object from string for easier parsing 

這裏是響應：

Outcome: Failure 
ePID: 
Error Id: 18 
Error Domain: Marketplace 
Error Severity: Error 
Error Category: System 
Error Message: Product ID value 841380031426 is not valid for product ID type UPC. 
Error Subdomain: MarketplaceCatalog 
Version: 1.3.1 
Timestamp: 2017-03-29T16:13:43.672Z 

呼叫適用於不在所述零件&附件目錄的產品，例如一本哈利波特書，但我無法讓它適用於任何汽車零件UPC代碼。我知道841380031426是一個有效的UPC，所以我很難過。任何幫助深表感謝。

感謝，

附：已經嘗試過Product-findProducts，Shopping-> FindProducts和Finding-> findItemsByProduct調用，但沒有成功。

Answer 1

UPC不是哈利波特upcitemdb.com/upc/841380031426

如果841380031426是產品ID使用

$xmlReq .= "<productIdentifier><productid>" . $upc . "</productid></productIdentifier>\n"; 

實況這裏： https://developer.ebay.com/Devzone/product/CallRef/types/ProductIdentifier.html

一更多錯誤：

$siteID = 'EBAY-MOTOR'; 

哈利波特圖書不會在ebay馬達
