Im starting to use the Oauth for Shopping API and also using HTTP headers and a curl with PHP.
Im wondering how i should ad the ItemID parameter? Is this how it should be done? Or should i set it later in the curl?
Or should it be specified in the url something like this?
curl_setopt($ch, CURLOPT_URL, "https://open.api.ebay.com/shopping?itemid=324779427803");
