Step 3: Create the formToken

Objective

Generate a formToken.

The formToken is a key generated by the gateway. It defines the payment context (amount, currency, order number, buyer contact details, etc.).

The formToken is the result of the response of the call to the Charge/CreatePayment REST Web Service. It is valid for 15 minutes.

I. Request for a simple payment

Example: .

amount : 9.90 €.
order: "myOrderId-999999",
buyer's email: "sample@example.com ".
