How to get eBay item URL based on item ID - php

Question

I would like to get the item URL based on the item ID. After searching, I found that I can use GetSingleItem to achieve my goal. However, I got an error:
eBay returned the following error(s):
2 : Unsupported API call.
The API call "GetSingleItem" is invalid or not supported in this release.
Here is my code (all configuration are correct because I can use GetOrders by using these configs):
$subverb = "GetSingleItem";
$requestXmlBody = '<?xml version="1.0" encoding="utf-8" ?>';
$requestXmlBody .= '<GetSingleItemRequest xmlns="urn:ebay:apis:eBLBaseComponents">';
$requestXmlBody .= "<ItemID>111986554711</ItemID>";
$requestXmlBody .= '</GetSingleItemRequest>';
//Create a new eBay session with all details pulled in from included keys.php
$session = new eBaySession($userToken, $devID, $appID, $certID, $serverUrl, $compatabilityLevel, $siteID, $subverb);
//send the request and get response
$responseXml = $session->sendHttpRequest($requestXmlBody);
if (stristr($responseXml, 'HTTP 404') || $responseXml == '')
die('<P>Error sending request');
//Xml string is parsed and creates a DOM Document object
$responseDoc = new DomDocument();
$responseDoc->loadXML($responseXml);
//get any error nodes
$errors = $responseDoc->getElementsByTagName('Errors');
$response = simplexml_import_dom($responseDoc);
$entries = $response->PaginationResult->TotalNumberOfEntries;
//if there are error nodes
if ($errors->length > 0) {
echo '<P><B>eBay returned the following error(s):</B>';
//display each error
//Get error code, ShortMesaage and LongMessage
$code = $errors->item(0)->getElementsByTagName('ErrorCode');
$shortMsg = $errors->item(0)->getElementsByTagName('ShortMessage');
$longMsg = $errors->item(0)->getElementsByTagName('LongMessage');
//Display code and shortmessage
echo '<P>', $code->item(0)->nodeValue, ' : ', str_replace(">", ">", str_replace("<", "<", $shortMsg->item(0)->nodeValue));
//if there is a long message (ie ErrorLevel=1), display it
if (count($longMsg) > 0)
echo '<BR>', str_replace(">", ">", str_replace("<", "<", $longMsg->item(0)->nodeValue));
} else { //If there are no errors, continue
if (isset($_GET['debug'])) {
header("Content-type: text/xml");
print_r($responseXml);
} else {
print("\n; 111986554711: " . $response->Item->ViewItemURLForNaturalSearch);
}
}
Any suggestion? Thank you .

Answer 1

As you discovered, you don't need the API to construct a simple eBay view item landing page URL.
The URL format you discovered works, but it's very old and might not be supported in full or for much longer.
Here's a simple URL format that is pretty current that you can use:
http://www.ebay.com/itm/122225724269

Answer 2

I got an answer without using api. Here is the answer: after I got item ID, I can use "http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=".$item_id to show my product on ebay.
I found this uri by using GetOrders API.
OrderArray.Order .TransactionArray.Transaction .Variation .VariationViewItemURL
Tip: "not optimized for natural search"
If anyone has any idea about "GetSingleItem", I am willing to know why my code doesn't work.
