$curl = curl_init();
curl_setopt_array($curl, array(
    CURLOPT_URL => $url,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_TIMEOUT => 30,
    CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
    CURLOPT_CUSTOMREQUEST => "POST",
    CURLOPT_POSTFIELDS => "<requestblock version=\"3.67\">\r\n  <alias>webservices@securetrading.com</alias>\r\n  <request type=\"AUTH\">\r\n    <operation>\r\n      <sitereference>test_site12345</sitereference>\r\n      <accounttypedescription>ECOM</accounttypedescription>\r\n    </operation>\r\n    <merchant>\r\n      <orderreference>Example AUTH</orderreference>\r\n      <termurl>https://www.example.com/termurl.cgi</termurl>\r\n      <name>Test Merchant</name>\r\n    </merchant>\r\n    <customer>\r\n      <ip>1.2.3.4</ip>\r\n    </customer>\r\n    <billing>\r\n      <amount currencycode=\"GBP\">2115</amount>\r\n      <town>Bangor</town>\r\n      <country>GB</country>\r\n      <payment type=\"VISA\">\r\n        <expirydate>10/2031</expirydate>\r\n        <pan>4111111111111111</pan>\r\n        <securitycode>123</securitycode>\r\n      </payment>\r\n    </billing>\r\n    <settlement/>\r\n  </request>\r\n</requestblock>",
    CURLOPT_HTTPHEADER => array(
        "accept-encoding: application/gzip",        
        "content-type: text/xml"
    ),
));
$response = curl_exec($curl);
