Performing Credit Card Transactions

Card Security Code Validation

38 Payflow Pro Developer’s Guide

Even though your processor may be certified for card security code, they may not be certified

for all card types (for example, Visa CVV2 or MasterCard CVC2). The list will change as

PayPal continues to enhance its service offering.

Card Security Code Results

If you submit the transaction request parameter for card security code (that is, the CVV2

parameter), the cardholder’s bank returns a Yes/No response in the CVV2MATCH response

parameter, as described in the first table below. Card security code results vary depending on

your processing platform, as described in the next table.

N OTE: Check with your acquiring bank to determine how they handle CVV2MATCH.

Example CVV2 Request Parameter String

This example request parameter string includes the CVV2 parameter:

"TRXTYPE=A&TENDER=C&PWD=x1y2z3&PARTNER=PayPal&VENDOR=SuperMerchant&USER=Sup

erMerchant&&ACCT=5555555555554444&EXPDATE=0308&AMT=123.00

&CVV2=567"

Card security code mismatches cause a non-approved result

(RESULT = 114).

No CVV2MATCH value is returned.

First Data International Transactions that have card security code mismatches can come

back as an approved transaction (RESULT = 0).

The match or mismatch information is indicated in the

CVV2MATCH value.

As with AVS, if the Authorisation was successful, you must make

a decision based on the CVV2MATCH value whether or not to

proceed with the order.
