Payment results will be returned to the merchant system once payment is done or the user abandons the payment process. HTTP POST is the only method that payment gateway returns all parameters to a merchant's return URL for real-time status update, which the merchant can configure in merchant admin. Merchant system should block all other methods or parameters from an untrusted source.

Value of “channel” in return URL

Merchant is strongly recommended to implement IPN(instant payment notification) in order to acknowledge (ACK) on the receiving of payment status from the payment gateway. There are 2 ways to implement IPN. Please refer to the IPN section for details.

Examples of Payment Endpoint

You may use the sample for all 3 endpoints, i.e. Return URL, Notification URL, and Callback URL by making little modification based on your own requirements.

Sample return URL script for PHP

<?php

$sec_key ="xxxxxxxxxxxx"; //Replace xxxxxxxxxxxx with Secret_Key

/********************************
*Don't change below parameters
********************************/
$tranID 	=	$_POST['tranID'];
$orderid 	=	$_POST['orderid'];
$status 	=	$_POST['status'];
$domain 	=	$_POST['domain'];
$amount 	=	$_POST['amount'];
$currency 	=	$_POST['currency'];
$appcode 	=	$_POST['appcode'];
$paydate 	                  =	$_POST['paydate'];
$skey		=	$_POST['skey'];

/***********************************************************
* To verify the data integrity sending by PG
************************************************************/
$key0 = md5( $tranID.$orderid.$status.$domain.$amount.$currency );
$key1 = md5( $paydate.$domain.$key0.$appcode.$sec_key );

if( $skey != $key1 ) $status= -1; // Invalid transaction. 
// Merchant might issue a requery to PG to double check payment status

if ( $status == "00" ) {
  if ( check_cart_amt($orderid, $amount) ) {
  /*** NOTE : this is a user-defined function which should be prepared by merchant ***/
  // action to change cart status or to accept order
  // you can also do further checking on the paydate as well
  // write your script here .....
  }
} else {
  // failure action. Write your script here .....
  // Merchant might send query to PG using Merchant requery
  // to double check payment status for that particular order.
}

// Merchant is recommended to implement IPN once received the payment status
// regardless the status to acknowledge the PG
