Integration of the payment window

There are two ways of integrating the payment window:

  • Simple: JavaScript integration
  • Advanced: POST/GET submission

Simple​

This is the easiest way to integrate ePay as it requires only a minimum of programming experience. All necessary code is automatically generated by the included JavaScript.

Examples​

Simple: Overlay​

<script charset="UTF-8" src="https://ssl.ditonlinebetalingssystem.dk/integration/ewindow/paymentwindow.js" type="text/javascript"></script>
<script type="text/javascript">
    paymentwindow = new PaymentWindow({
        'merchantnumber': "ENTER YOUR MERCHANT NUMBER HERE",
        'amount': "10095",
        'currency': "DKK"
    });
</script>

<input onclick="javascript: paymentwindow.open()" type="button" value="Go to payment">

Simple: Integrated payment form​

Advanced​

This method is for advanced users only. The integration is based on building an HTML form and submitting it to the payment window by either POST or GET. The parameters must be defined in the input fields (usually these are of the type hidden).

It's also possible to link to the payment window with the parameters set in GET.

The URL to use is: https://ssl.ditonlinebetalingssystem.dk/integration/ewindow/Default.aspx

  action="https://ssl.ditonlinebetalingssystem.dk/integration/ewindow/Default.aspx"
