RDP Hosted and Direct Tokenization API

Hosted Tokenization API – Push Notification Result

Push Notification Description

After the first phase, RDP payment gateway will process the tokenization process. The result
of the payment or transaction will then be communicated to merchant system through two
ways or methods. One of the methods is called ‘Push Notification’.

As the name suggest, RDP push the tokenization result to the merchant’s system as is indicated
by the URL that is sent within the request under the field of notify_url.

The following are the important points of this push notification:

It is a POST request toward notify_url.
The tokenization result is in a JSON formatted information
The tokenization result is put inside the BODY of the request
Merchant is required to response with status of 200 (OK) by default when no errors is happened, majority of web framework returns status 200.
In the case where merchant is not returning status 200, RDP system will be trying for 3 times consecutively.

Push Notification Handling Example

Below is the sample code for push notification handling in PHP programming language.

/* 
This sample code is retrieving the result from the BODY of an RDP push
notification, and parse the json into array, traverse and print it out to
the screen.
By default a successful PHP script returns status 200
*/

$content = '';
/* RETRIEVE RESULT FROM BODY */
$querystring = @file_get_contents('php://input');

$arrParam = array();
$prefix = '';
try {
   $arrParam = json_decode($querystring, true);
   $content .= $querystring;
   foreach($arrParam as $key => $val) {
      $content .=$key.'='.$val."\n";
   } 

   $prefix = "";
   if(isset($arrParam["mid"])) $prefix .= $arrParam["mid"];
   $prefix .= "_";
   if(isset($arrParam["transaction_id"])) $prefix .=
      $arrParam["transaction_id"];

   file_put_contents(
     "notif_log/".$prefix."-".date('Y_m_d_H_i_s').rand(100,999).'-res'.'.txt', $content);
}
catch (Exception $e) {
   file_put_contents(
      "notif_log/".$prefix."-".date('Y_m_d_H_i_s').rand(100,999). '-error-res'.'.txt',
      $e->getMessage());
}
