Submitting Credit Card Transactions

Submitting Credit Transactions

Submitting Credit Transactions

The credit transaction (TRXTYPE=C) refunds the specified amount back to the cardholder. A

credit transaction can contain a reference to the original transaction (referenced) or not (non-

referenced) depending on how your account is setup. To issue a credit, the original transaction

can only be one of the following: a Sale (TRXTYPE=S), Delayed Capture (TRXTYPE=D) or

Voice Authorization (TRXTYPE=F). It is recommended that the merchant issue a credit only if

the original transaction has already settled. Even though it is possible to issue a credit to a

transaction that has not settled, it is recommended that you void such transactions.

Both the credit transaction and the original transaction will appear on the customer’s

statement.

Required Credit Transaction Parameters

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

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

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

provide the credit card information. As an example, Sally Smith calls you on the phone 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

non-referenced credits are allowed.

Non-Referenced Credits Not Allowed

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

the following parameter:

Parameter Description

ORIGID (Required by some transaction types) ID of the original transaction referenced.

The PNREF parameter returns this ID, and it appears as the Transaction ID in

PayPal Manager reports.

Limitations: 12 case-sensitive alphanumeric characters.
