We have several forms that require taking a payment. So the user fills in the form answers certain questions and based on the answers a few is calculated. In order for the form to proceed they have to make a payment. We want to be able to pass off the form ID along with fee to a payment gateway to handle the fee processing. The payment gateway then sends back a confirmation or payment being made and receipt number which also has to be handled by the Nintex form & workflow.
Has as anyone done this? In particular with the payment gateway provider SecurePay in Australia?
