Submitting Void Transactions
The Void transaction (TRXTYPE=V) prevents a transaction from being settled.
As part of its internal process, PayPal makes reasonable effort to process authorization
reversals for void transactions for debit and credit cards. Because the honoring of
authorization reversals is ultimately decided by the bank or issuer, there is no accurate way to
determine if an individual bank or issuer has honored an authorization reversal request.
N OTE: For more information on authorization reversals, see
http://en.wikipedia.org/wiki/Authorization_hold.
For information on authorization reversals related to the Paymentech New Hampshire and
FDMS North processors, see “Processors Requiring Additional Transaction Parameters” on
page 65.
When To Use a Void Transaction
Follow these guidelines:
z You can void Delayed Capture, Sale, Credit, Authorization, and Voice Authorization
transactions. You cannot void a Void transaction.
z You can only use a Void transaction on a transaction that has not yet settled. To refund a
customers money for a settled transaction, you must submit a Credit transaction.
Required Void Transaction Parameters
To submit a Void transaction, you must pass the following parameter:
ORIGID
Set ORIGID to the PNREF (Transaction ID in PayPal Manager reports) value returned for the
original transaction.
Fields Copied From the Original Transaction into the Void Transaction
The following fields are copied from the original transaction into the Void transaction (if they
exist in the original transaction). If you provide a new value for any of these parameters when
submitting the Void transaction, then the new value is used. (Exceptions are ACCT, EXPDATE,
and SWIPE. These parameters retain their original values).
TABLE 4.7 Void 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.
