Submitting Credit Card Transactions

Submitting Reference Transactions (Tokenization)

Example Reference Transaction

In this example, you authorize an amount of $100 for a shipment and charge $66 for the first

partial shipment using a normal delayed capture. You charge the $34 for the final part of the

shipment using a reference transaction to draw credit card and shipping address information

from the initial authorization transaction.

This example procedure creates a reference transaction:

1. Submit the initial transaction, such as an authorization.

You use an authorization transaction for the full amount of the purchase of $100 as shown

in this transaction request:

TRXTYPE=A&TENDER=C&PWD=x1y2z3&PARTNER=PayPal&VENDOR=SuperMerchant

&USER=SuperMerchant&ACCT=5555555555554444&EXPDATE=1215&AMT=100.00

&INVNUM=123456789&BILLTOSTREET=5199 MAPLE&BILLTOZIP=94588

Note the value of the PNREF in the response:

RESULT=0&PNREF=VXYZ01234567&RESPMSG=APPROVED&AUTHCODE=123456&AVSADDR=Y

&AVSZIP=N

NOTE: The PNREF returned in the original transaction is valid in reference transactions for

12 months.

If the original transaction was processed by the PayPal processor, pass either the

PPREF or PNREF of the original transaction in the ORIGID parameter.

2. Capture the authorized funds for a partial shipment of $66.

When you deliver the first $66 worth of product, you use a normal delayed capture

transaction to collect the $66. Set ORIGID to the value of PNREF in the original

authorization as in this transaction request.

TRXTYPE=D&PWD=x1y2z3&PARTNER=PayPal&VENDOR=SuperMerchant

&USER=SuperMerchant&ORIGID=VXYZ01234567&AMT=66.00

The following is the response:

RESULT=0&PNREF=VXYZ01234568&AUTHCODE=25TEST&AVSADDR=Y&AVSZIP=N

NOTE: The TENDER parameter is not required in this step. The TENDER of the capture will

be the same as that of the original transaction.
