if(curl_errno($ch))

}

When above code is run I am getting below error :

HTTP/1.1 404 Not Found

Please someone help, I am struggling with this for last 1 week but no success.

After a long struggle found the solution. Use below code it worked for me.

 <?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,
    "https://api.clickbank.com/rest/1.3/tickets/627JE7CZ/?type=rfnd&comment=&reason=ticket.type.refund.7&refundType=FULL");
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
/**
 * ClickBank doesn't allow POST parameters to be sent in; however, for the CURL POST to work correctly, the
 * CURL_POSTFIELDS option must be set, so we'll just set it to empty and put all our request parameters on the URL
 */
curl_setopt($ch, CURLOPT_POSTFIELDS, "");
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    "Accept: application/xml",
    "Authorization:DEV-enter your dev key here:API-enter your clerk key here"
));
$result = curl_exec($ch);
curl_close($ch);
?>
