Performing Credit Card Transactions

Submitting Credit Transactions

The Credit transaction (TRXTYPE=C) refunds the specified amount to the cardholder.

Required Credit Transaction Parameters

The required parameter data for a Credit transaction depends on the Allow non-referenced

credits security setting for your Payflow Pro account. A non-referenced credit is a Credit

transaction that does not use the credit card information from an existing transaction. Credit

card information must be supplied. As an example, Sally Smith calls you on the telephone to

cancel an order from your business. To refund her money, you credit her credit card by

submitting a non-referenced Credit transaction.

N OTE: The PayPal processor does not support non-referenced credits.

Guidelines and parameter requirements for Credit transactions differ depending on whether or

not non-referenced credits are allowed.

Non-Referenced Credits Not Allowed

When non-referenced credits are not allowed (the setting recommended by PayPal), then

Credit transactions are permitted only against existing Sale, Delayed Capture, and Voice

Authorisation transactions. To submit a Credit transaction when non-referenced credits are not

allowed, you must pass the following parameter:

ORIGID

Set the value of ORIGID to the PNREF value returned for the original transaction. (PNREF is

displayed as the Transaction ID in PayPal Manager reports. For details on PNREF, see

Chapter 4, “Responses to Credit Card Transaction Requests.”) If you do not specify an

amount, then the amount of the original transaction is credited to the cardholder.

Non-Referenced Credits Allowed

When non-referenced credits are allowed, then Credit transactions are permitted in any

amount up to the transaction limit for the credit card account that you specify. To submit a

Credit transaction when non-referenced credits are not allowed, you must pass values for the

following parameters:

ACCT

EXPDATE

AMT

IMPORTANT: The default security setting for Payflow Pro accounts is Allow

non-referenced credits = No, so sending the ORIGID is the preferred method

for performing Credit transactions. Using the ACCT, EXPDATE, or AMT

parameters for such accounts leads to Result code 117 (failed the security

check). For information on setting the security settings, see PayPal Manager

online help.
