When calling this method TransactionAmount must be set to 0. Set either CustomerAddress or CustomerZip to perform AVS checks. Set CVVData to perform CVV checks.
The following combinations are supported:
| Card Type | Verification | w/ AVS | w/ CVV | w/ AVS and CVV | Swiped w/ AVS |

Important Note: You must ping your list of service provider URLs and update the URL property to the service provider with the shortest response time every 100 transactions, as well as when your application initially starts. This is not a normal ICMP ping - to determine the fastest transaction URL you must use the special Ping method inside the FDMSRegister component. (You may update your list of service provider URLs with the FDMSRegister component's ServiceDiscovery method).
