Payeezy：如何在php中对“标记完成”事务进行“预授权”事务

Question

Payeezy payment gateway has been integrated successfully with php. Kept transaction type as "AUTH_ONLY". To make the complete transaction will go to the admin panel and make it as tagged completion as shown in screen shot.

Now we want to allow the merchant to add the shipping fee, compute the total from within our application, and then send a request back to Payeezy with the total amount to be charged against the transaction tag that was received earlier and complete the previous pre-authorization as completed.

Here is the link how to achieve it, but unable to understand how to do with php.

Thanks in advance.

With regards, Sudhir

Answer 1

I got the proper code to do this. Here is the proper code in php and fill all the variables with proper payeezy values.

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");
$hashstr = "POST
text/xml; charset=utf-8
" . sha1($request) . "
" . $hashtime . "
" . parse_url($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 . "
Authorization: GGE4_API " . $keyid . ":" . $authstr . "
x-gge4-date: " . $hashtime . "
x-gge4-content-sha1: " . sha1($request));
      } 
   else {
    stream_context_set_option($context,array("http" => array("header" => "aut horization: GGE4_API " . $keyid . ":" . $authstr . "
x-gge4-date: " . $hashtime . "
x-gge4-content-sha1: " . sha1($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){
