Credit Card Transactions
Parameters Used in Credit Card Transactions
LASTNAME (Optional but recommended) Account holder's last name.
Limitations: 30 alphanumeric characters.
STREET (Optional) The cardholder’s street address (number and street name).
The STREET address is verified by the address verification service.
Limitations: 30 alphanumeric characters.
SWIPE (Required for card-present transactions only) Used to pass the Track 1 or Track 2 data
(card’s magnetic stripe information) for card-present transactions. Include either
Track 1 or Track 2 data—not both. If Track 1 is physically damaged, the point-of-sale
(POS) application can send Track 2 data instead.
The track data includes the disallowed = (equal sign) character. To enable you to use
the data, the SWIPE parameter must include a length tag specifying the number of
characters in the track data. For this reason, in addition to passing the track data, the
POS application must count the characters in the track data and pass that number.
Length tags are described in “Using Special Characters in Values” on page 20.
N OTE: SWIPE (card-present transactions) are not supported by the PayPal processor..
Limitations: Alphanumeric characters.
TENDER (Required) The method of payment. Values are:
z A = Automated clearinghouse
z C = Credit card
z D = Pinless debit
z K = Telecheck
z P = PayPal
See the Payflow ACH Payment Service Guide for details on the Automated
clearinghouse tender type.
TRXTYPE (Required) Indicates the type of transaction to perform. Values are:
z S = Sale transaction
z C = Credit
z A = Authorization
z D = Delayed Capture
z V = Void
z F = Voice Authorization
z I = Inquiry
z N = Duplicate transaction
N OTE: A type N transaction represents a duplicate transaction (version 4 SDK or
HTTPS interface only) with a PNREF the same as the original. It appears only
in the PayPal Manager user interface and will never settle.
ZIP (Optional) Account holder’s 5- to 9-digit ZIP (postal) code.
Limitations: Nine characters maximum. Do not use spaces, dashes, or non-numeric
characters.
