Can you point me to a list of what are all the different possible codes for AVS and CVV?
I found the PayPal codes (PayPal address verified Y/N, PayPal account verified Y/N) but would like to know for our credit card transactions too (custom=TD OnlineMart/Bambora):
For a custom payment processor I don't think anybody here would know the answer to that. Probably need to have a look at the processor's API documentation and at your code to determine what they send back and how it's presented.
