$path = "$userAccountId.$orderId.$amount.$currency.$chargebackProtection";

$hash = hash_hmac('sha256', $path, $api_key, false);

You can generate the API key in Setting > Application > API

 console.log(e.data.message);
 console.log(e.data.transaction_ref_no); //Gateway transaction reference #
 alert(' Event message : ' + e.data.message);

}
