Question

I am trying to integrate the hosted checkout with MasterCard.

guide: https://ap-gateway.mastercard.com/api/documentation/integrationGuidelines/index.html?locale=en_US

after complete ACS Emulator page, It's return "Your transactions was unsuccessful" error. How can I fix this error?

<?php

$orderid = "13441568";
$merchant = "XXXXX";
$apipassword = "XXXXX";
$returnUrl = "http://localhost/mpgs";
$currency = "USD";
$amount ="10.00";
$apiUsername= "merchant.xxx";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"https://test-gateway.mastercard.com/api/nvp/version/51");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "apiOperation=CREATE_CHECKOUT_SESSION&apiPassword=$apipassword&interaction.returnUrl=$returnUrl&apiUsername=$apiUsername&merchant=$merchant&order.id=$orderid&order.amount=$amount&order.currency=$currency");

$headers = array();
$headers[] = 'Content-Type: application/x-www-form-urlencoded';
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

$result = curl_exec($ch);
if(curl_errno($ch)) {
   echo 'ERROR:'. curl_error($ch);
}

curl_close($ch);

$sessionid = explode("=", explode("&", $result)[2])[1];
