Pay Now iFrame is a UI component which allows for the simple integration of Pay Now Buttons into your website (e.g.. wordpress, booking engine, booking website) which generate secure payment forms to collect customer payment information. The information collected includes customer first and last name, card number, cvv code, expiration date, and billing information. This will allow you to process transactions for your customers without having to handle sensitive customer data.

Put this Script tag wherever you want to generate a button or auto load iframe change data-attributes’ values as per your account & payment request.

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

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

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

}
