Credit Card Transactions
Submitting Card-Present (SWIPE) Transactions
3. Submit a new Sale transaction or Authorization/Delayed Capture transaction of $34 for the
rest of the shipment.
Once you have shipped the remainder of the product, you can collect the remaining $34 in
a Sale transaction that uses the initial Authorization as a reference transaction. (This is a
Sale transaction because only one Delayed Capture transaction is allowed per
Authorization.) This is the Sale transaction request:
TRXTYPE=S&TENDER=C&PWD=x1y2z3&PARTNER=PayPal&VENDOR=SuperMerchant&USER=S
uperMerchant&ORIGID=VXYZ01234567&AMT=34.00
This is the response:
RESULT=0&PNREF=VXYZ01234569&AUTHCODE=25TEST&AVSADDR=Y&AVSZIP=N
Submitting Card-Present (SWIPE) Transactions
Payflow Pro supports card-present transactions (face-to-face purchases).
N OTE: SWIPE (card-present) transactions are not supported by the PayPal processor.
Follow these guidelines to take advantage of the lower card-present transaction rate:
z Contact your merchant account provider to ensure that they support card-present
transactions.
z Contact PayPal Customer Service to request having your account set up properly for
accepting and passing swipe data.
z If you plan to process card-present as well as card-not-present transactions, set up two
separate Payflow Pro accounts. Request that one account be set up for card-present
transactions, and use it solely for that purpose. Use the other for card-not-present
transactions. Using the wrong account may result in downgrades.
z A Sale is the preferred method to use for card-present transactions. Consult
with your acquiring bank for recommendations on other methods.
