Submitting Credit Card Transactions

Submitting Credit Transactions

60 31 July 2012 Gateway Developer Guide and Reference

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

Manager reports display the PNREF as the Transaction ID.) If you do not specify an amount,

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

Non-Referenced Credits Allowed

When non-referenced credits are allowed, 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:

 ACCT

 EXPDATE

 AMT

NOTE: The default security setting for Gateway accounts is Allow non-referenced credits =

No. Sending the ORIGID is the preferred method for performing credit transactions.

Using the ACCT, EXPDATE, or AMT parameters for such accounts leads to the return of

RESULT value 117 (failed the security check). To help reduce fraud, PayPal

recommends that you not activate non-referenced credits unless you have a business

reason. For information on setting the security settings, see PayPal Manager online

help.

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

Manager reports display the PNREF as the Transaction ID.) If you do not specify an amount,

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

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, the new value is used. (Exceptions are ACCT, EXPDATE, and

SWIPE. These parameters retain their original values.)

NOTE: These fields are not copied for referenced credits: TAXAMT, TAXEXEMPT, DUTYAMT,

FREIGHTAMT, and (for American Express only) DESC4.

NOTE: For processors that use the RECURRING parameter: If you set the RECURRING

parameter to Y in the original transaction, this setting is ignored when forming the

credit transaction.

Parameter Description

ORIGID (Required by some transaction types) ID of the original transaction that is being

referenced. The PNREF parameter returns this ID, and it appears as the

Transaction ID in PayPal Manager reports.
