URL Fields

In your integration, you would calculate these fields within your code (process.php based on this example) and not expose these to the card holder on this page, or pass them as hidden fields.
version
order.id
Order ID of the existing Authorization transaction you wish to update.
transaction.id

Transaction Fields
method ** See Note 1 Below

Note 1: This field is used by this example to set the HTTP Method for sending the transaction. In your integration, you should determine the HTTP Method in your code (process.php based on this example) and never display it to the card holder or pass it as a hidden field.
