I am using PayPal for credit card verification. VISA cards are working fine and I am receiving payments through them, but in case of AMEX (American Express) cards its not working. Its giving me the following error,
”Gateway Decline: This transaction cannot be processed. Please enter a valid Credit Card Verification Number.”
As VISA cards are working fine, so this may not be a problem at the PayPal end, I am not sure but I think there is some problem with magento, as in VISA cards the CVC number is of 3-digits and in AMEX its 4-digits, So may be Magento is sending only 3-digits to PayPal for verification and hence its replying with the above error.
I am using Magento ver. 1.1.6
Please tell me why its creating problem and how to solve this problem.
“Could someone from support team please respond?”
