How do I get credit card verification code (CVN) in ReserveOrderAmountAction action?

[Former Member]

Hi, We have implemented an integration with a payment gateway. This integration occurs when the process action ReserveOrderAmountAction is executed. There we have a CreditCardPaymentInfo (process.getOrder().getPaymentInfo() ). We need to get the credit card verification number typed by user to send to the payment gateway but we are unable to find it on this paymentInfo. We have all information we need but no CVN. How can we get this information at this code point?

Thanks.
