I am writing a script to update the Authorize.net credit card for an ARB subscription. I see that CVV is not required. Is CVV only entered at the initial setup with a subscription?
What about if the user is changing the card entirely for a subscription?
Ok, so does that mean that it is just for show? They could enter the wrong CVV and it makes no difference?
Also, as a side note, is there any validation on the name associated with the card on file?
