I am using Paypal / Payflow Pro's Authorization Transaction (TRXTYPE=A) to validate credit card information. I am passing 0.00 as the AMT.
This works fine and can filter out wrong account number, expiration date as well as wrong CVV2 code by checking CVV2MATCH = X in the return string.
However, there is a problem with BILLTOZIP validation. Return value is always AVSZIP = Y even if I entered the wrong ZIP.
What's weird is... The CC used for this transaction is from US. I used a CC from Philippines and wrong ZIP was being recognized.
