Some FoxyCart functionality may require or allow a transaction to be processed without a Card Security Code (the “CSC”, the numbers on the back of most cards). Some gateways, however, may disallow transactions without a CSC passed through. The situations where the CSC will not be transferred to the gateway are:
If you're using this functionality we strongly recommend turning off the CSC requirements in your gateway's settings, if possible. FoxyCart will always require a CSC, so a CSC will be sent when possible, but there are certain situations where the CSCs simply might not be available (as with recurring billing / subscriptions).
Also, please note that the CSC is not allowed to be stored, per PCI DSS.
Gateways that may have a problem processing transactions without a CSC include:
Almost every gateway provider also provides their customers with test accounts (also called development accounts or sandbox accounts) for use on the gateway's test environment. A test account will work on the test environment, but will not work on the live environment. Similarly, a live account will work on the live environment (the one that processes real transactions from real customers), but will not work on the gateway's own test environment. The two environments are generally completely separate, and any account on one will not work on the other.
To make testing easier for FoxyCart users, FoxyCart provides the ability to enter your own test account information with which to test. What is critical to understand is that, in almost all cases, a live account will not work on if the test gateway is selected in FoxyCart. FoxyCart will send the transaction to entirely separate systems based on your store's settings.
