Quickpay Cancel API

Hej

Kan nogen se hvad der er galt her, siden det ikke virker:

<?php
    $protocol = '3';
    $msgtype = 'cancel';
    $merchant = '27511171';
    $transaction = '35790454';
    $secret = 'minkodeher';

    $md5checked = md5($protocol . $msgtype . $merchant . $transaction . $secret);

   
$url = "https://secure.quickpay.net/ (...)
$postdata = "protocol=3&msgtype=cancel&merchant=27511171&transaction=35790454&md5check=$md5checked";


$ch = curl_init();    // initialize curl handle
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0');
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);

$result = curl_exec($ch);

$xml = new SimpleXMLElement($result);
echo $xml->qpstatmsg;

?>

Prøver at sende til Quickpay gennem deres API. Har fundet noget af koden her i forummet.

Disse oplysninger er givet fra Quickpay:

The QuickPay API is an open protocol that enables merchants to handle payments in a simple manner. The protocol is based on SSL encrypted HTTP communication and all actions are perfomed by sending a HTTP POST request to https://secure.quickpay.dk/ (...) (See Example 1). Upon each request sent, QuickPay will respond with a simple XML document (See Example 2). Please notice: do not send API requests to https://secure.quickpay.dk/ (...) /form/ is only for authorizes using the Quickpay Payment Window.

Example 1. HTTP POST request for cancel

POST /api HTTP/1.1
