I have a client (twelvesouth.com) that is using the "cc_type" field sent from the API transaction feed to reconcile their accounting. They've noticed a discrepancy between what FoxyCart provides and the card type Authorize.net reports as being used. It seems that the FC will default to "Visa" in some cases where another card type has been used.
The only common denominator we can see is that when a card type is listed incorrectly it gets listed as Visa. Any ideas?
