The card verification number (CVN), which is printed or embossed on the back of the card, can be sent with the request and verified to help reduce the risk of fraud.
Each payment card company has its own name for this value:
- Mastercard calls it the Card Validation Code (CVC2).To use the CVN, include thecard_cvNumberfield in the request. This number is never transferred during card swipes and should be known only by the cardholder.
The reply message includes a raw response code and a mapped response code.
- Raw Response Code
- The value returned by the processor. This value is returned in the authorization reply in theprocessorInformation.cardVerification.resultCodefield. Use this value only for debugging purposes; do not use it to determine the card verification response.
- Mapped Response Code
- The predefined CyberSource value that corresponds to the raw response code. This value is returned in theprocessorInformation.cardVerification.resultCodeRawfield. See “CVN Codes” in
