Credit Card Transactions
Submitting Credit 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.
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
Authorization 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.) 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 allowed, you must pass values for the
following parameters:
z ACCT
z EXPDATE
z AMT
T
ABLE 4.5 Credit required parameter
Parameter Description
ORIGID (Required by some transaction types) ID of the original transaction that is being
referenced. This ID is returned by the PNREF parameter and appears as the
Transaction ID in PayPal Manager reports.
Limitations: 12 case-sensitive alphanumeric characters.
