PHP Example - REST (JSON)

URL Fields
Order and Transaction IDs are required and used to calculate the URL along with the version and merchant ID. In your integration, you would use the values for these fields used in the initiate browser payment request within your code (process.php based on this example) and not expose these to the payer on this page, or pass them as hidden fields.
version
order.id	Order ID of the existing Initiate Browser Payment transaction you wish to confirm
transaction.id	Transaction ID of the existing Initiate Browser Payment transaction you wish to confirm
Transaction Fields
method	** See Note 1 Below
apiOperation
order.amount
order.currency


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 payer or pass it as a hidden field.
