First data payment gateway integration soap fault error - php

Question

Hi I am trying to integrate First data payment gateway integration in soap request method using php. I have downloaded the working sample code from first data but when i am trying to submit a payment with the sample code they gave it is throwing me an error.
The entire php code is
<?php
class SoapClientHMAC extends SoapClient {
public function __doRequest($request, $location, $action, $version, $one_way = NULL) {
global $context;
$hmackey = "***********************"; // <-- Insert your HMAC key here
$keyid = "*****"; // <-- Insert the Key ID here
$hashtime = date("c");
$hashstr = "POST\ntext/xml; charset=utf-8\n" . sha1($request) . "\n" . $hashtime . "\n" . parse_url($location,PHP_URL_PATH);
$authstr = base64_encode(hash_hmac("sha1",$hashstr,$hmackey,TRUE));
if (version_compare(PHP_VERSION, '5.3.11') == -1) {
ini_set("user_agent", "PHP-SOAP/" . PHP_VERSION . "\r\nAuthorization: GGE4_API " . $keyid . ":" . $authstr . "\r\nx-gge4-date: " . $hashtime . "\r\nx-gge4-content-sha1: " . sha1($request));
} else {
stream_context_set_option($context,array("http" => array("header" => "authorization: GGE4_API " . $keyid . ":" . $authstr . "\r\nx-gge4-date: " . $hashtime . "\r\nx-gge4-content-sha1: " . sha1($request))));
}
return parent::__doRequest($request, $location, $action, $version, $one_way);
}
public function SoapClientHMAC($wsdl, $options = NULL) {
global $context;
$context = stream_context_create();
$options['stream_context'] = $context;
return parent::SoapClient($wsdl, $options);
}
}
$trxnProperties = array(

);
$client = new SoapClientHMAC("https://api.demo.globalgatewaye4.firstdata.com/transaction/v12/wsdl");
$trxnResult = $client->SendAndCommit($trxnProperties);
if(#$client->fault){
// there was a fault, inform
print "<B>FAULT: Code: {$client->faultcode} <BR />";
print "String: {$client->faultstring} </B>";
$trxnResult["CTR"] = "There was an error while processing. No TRANSACTION DATA IN CTR!";
}
//Uncomment the following commented code to display the full results.
echo "<H3><U>Transaction Properties BEFORE Processing</U></H3>";
echo "<TABLE border='0'>\n";
echo " <TR><TD><B>Property</B></TD><TD><B>Value</B></TD></TR>\n";
foreach($trxnProperties as $key=>$value){
echo " <TR><TD>$key</TD><TD>:$value</TD></TR>\n";
}
echo "</TABLE>\n";
echo "<H3><U>Transaction Properties AFTER Processing</U></H3>";
echo "<TABLE border='0'>\n";
echo " <TR><TD><B>Property</B></TD><TD><B>Value</B></TD></TR>\n";
foreach($trxnResult as $key=>$value){
$value = nl2br($value);
echo " <TR><TD valign='top'>$key</TD><TD>:$value</TD></TR>\n";
}
echo "</TABLE>\n";
// kill object
unset($client);
?>
When i submit the payment my page comes to this particular code and the error it throws is
Fatal error: Uncaught SoapFault exception: [HTTP] in C:\wamp\www\Fd\php\process.php:49 Stack trace: #0 C:\wamp\www\Fd\php\process.php(49): SoapClient->__doRequest('<?xml version="...', 'https://api.dem...', 'http://secure2....', 1, 0) #1 [internal function]: SoapClientHMAC->__doRequest('<?xml version="...', 'https://api.dem...', 'http://secure2....', 1, 0) #2 C:\wamp\www\Fd\php\process.php(104): SoapClient->__call('SendAndCommit', Array) #3 C:\wamp\www\Fd\php\process.php(104): SoapClientHMAC->SendAndCommit(Array) #4 {main} thrown in C:\wamp\www\Fd\php\process.php on line 48.
And the line 48 is
return parent::__doRequest($request, $location, $action, $version, $one_way);
I couldn't really figure out what this error is. Googled and tried various solutions but no success.Also I have both the soap and openssl enabled in my php server if that is of any help.
Thanks in advance for any help.

Answer 1

A little bit too late but anyways... just dump that garbage SOAP code, heres my early stage JSON and CURL version
<?php
class FirstData
{
protected $host = "api.demo.globalgatewaye4.firstdata.com";
protected $protocol = "https://";
protected $uri = "/transaction/v12";
/*Modify this acording to your firstdata api stuff*/
protected $hmackey = "XXXXXXXXXXXXXXXXXXXXXXX";
protected $keyid = "XXXXX";
protected $gatewayid = "XX000-00";
protected $password = "XXXXXXX";
public function request()
{
$location = $this->protocol . $this->host . $this->uri;
$request = array(
'transaction_type' => "00",
'amount' => 10.00,
'cc_expiry' => "0415",
'cc_number' => '4111111111111111',
'cardholder_name' => 'Test',
'reference_no' => '23',
'customer_ref' => '11',
'reference_3' => '234',
'gateway_id' => $this->gatewayid,
'password' => $this->password,
);
$content = json_encode($request);
var_dump($content);
$gge4Date = strftime("%Y-%m-%dT%H:%M:%S", time()) . 'Z';
$contentType = "application/json";
$contentDigest = sha1($content);
$contentSize = sizeof($content);
$method = "POST";
$hashstr = "$method\n$contentType\n$contentDigest\n$gge4Date\n$this->uri";
$authstr = 'GGE4_API ' . $this->keyid . ':' . base64_encode(hash_hmac("sha1", $hashstr, $this->hmackey, true));
$headers = array(
"Content-Type: $contentType",
"X-GGe4-Content-SHA1: $contentDigest",
"X-GGe4-Date: $gge4Date",
"Authorization: $authstr",
"Accept: $contentType"
);
//Print the headers we area sending
var_dump($headers);
//CURL stuff
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_URL, $location);
//Warning ->>>>>>>>>>>>>>>>>>>>
/*Hardcoded for easier implementation, DO NOT USE THIS ON PRODUCTION!!*/
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
//Warning ->>>>>>>>>>>>>>>>>>>>
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_VERBOSE, 0);
curl_setopt($ch, CURLOPT_HEADER, 1);

//This guy does the job
$output = curl_exec($ch);
//echo curl_error($ch);
$header_size = curl_getinfo($ch, CURLINFO_HEADER_SIZE);
$header = $this->parseHeader(substr($output, 0, $header_size));
$body = substr($output, $header_size);
curl_close($ch);
//Print the response header
var_dump($header);
/* If we get any of this X-GGe4-Content-SHA1 X-GGe4-Date Authorization
* then the API call is valid */
if (isset($header['authorization']))
{
//Ovbiously before we do anything we should validate the hash
var_dump(json_decode($body));
}
//Otherwise just debug the error response, which is just plain text
else
{
echo $body;
}
}
private function parseHeader($rawHeader)
{
$header = array();
//http://blog.motane.lu/2009/02/16/exploding-new-lines-in-php/
$lines = preg_split('/\r\n|\r|\n/', $rawHeader);
foreach ($lines as $key => $line)
{
$keyval = explode(': ', $line, 2);
if (isset($keyval[0]) && isset($keyval[1]))
{
$header[strtolower($keyval[0])] = $keyval[1];
}
}
return $header;
}
}
$firstdata = new FirstData();
$firstdata->request();

Answer 2

I tried SOAP with no success, finally had to switch to JSON.
#KukoBit's answer worked for me. Only problem was the date string which is expected in GMT. I solved it by calculating date as follows:
$gge4Date = strftime("%Y-%m-%dT%H:%M:%S", time() - (int) substr(date('O'), 0, 3)*60*60) . 'Z';
Hope this helps.
ps. I know this should be a comment, but due to points restrictions, I cannot.

Just a heads up for those who keep getting 'Unauthorized Request. Bad or missing credentials.' .
MAKE SURE you are NOT using your PRODUCTION credentials for DEMO environment. They will not work. Stop pulling your hair out :)
all you have to do is, goto
https://firstdata.zendesk.com/entries/21510561-first-data-global-gateway-e4sm-demo-accounts
Signup for a free demo. you will generate your hmac, and get your other data there , just like you do in production.

Answer 4

$client = new SoapClientHMAC("https://api.demo.globalgatewaye4.firstdata.com/transaction/v12/wsdl");
remove ".demo" => "https://api.globalgatewaye4.firstdata.com/transaction/v12/wsdl"
You use live access in api first data
