Performing Credit Card Transactions

Submitting Void Transactions

30 Payflow Pro Developer’s Guide

Fields Copied From the Original Transaction into the Credit Transaction

The following fields are copied from the original transaction into the Credit transaction (if

they exist in the original transaction). If you provide a new value for any of these parameters

when submitting the Credit transaction, then the new value is used. (Exceptions are ACCT,

EXPDATE, and SWIPE. These parameters retain their original values).

N OTE: These fields are not copied for referenced credits: TAXAMT, TAXEXEMPT,

DUTYAMT, FREIGHTAMT, and (for American Express only) DESC4.

N OTE: For processors that use the RECURRING parameter: If the RECURRING parameter

was set to Y for the original transaction, then the setting is ignored when forming the

Credit transaction.

Credit Transaction Parameter Strings

This is an example Credit transaction string (non-referenced credits not allowed):

"TRXTYPE=C&TENDER=C&PARTNER=PayPal&VENDOR=SuperMerchant

&USER=SuperMerchant&PWD=x1y2z3&ORIGID=VPNE12564395"

This is an example Credit transaction string (non-referenced credits allowed):

"TRXTYPE=C&TENDER=C&PARTNER=PayPal&VENDOR=SuperMerchant

&USER=SuperMerchant&PWD=x1y2z3&ACCT=5555555555554444&EXPDATE=0308

&AMT=123.00"

Submitting Void Transactions

The Void transaction (TRXTYPE=V) prevents a transaction from being settled but does not

release the Authorisation (hold on funds) on the cardholder’s account.
