Performing Credit Card Transactions

Recharging to the Same Credit Card (Reference Transactions)

Example Reference Transaction

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

partial shipment using a normal Delayed Capture transaction. 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 Authorisation transaction.

Step 1 Submit the Initial transaction (Authorisation in this example)

You use an Authorisation transaction for the full amount of the purchase of $100, for example:

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

erMerchant&ACCT=5555555555554444&EXPDATE=0308&AMT=100.00&INVNUM=123456789&S

TREET=5199 MAPLE&ZIP=94588"

Note the value of the PNREF in the response:

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

IP=N

Step 2 Capture the authorised 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

Authorisation, for example:

"TRXTYPE=D&TENDER=C&PWD=x1y2z3&PARTNER=PayPal&VENDOR=SuperMerchant&USER=Sup

erMerchant&O RIGID=VXYZ01234567&AMT=66.00"

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

Step 3 Submit a new Sale 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 Authorisation as a reference transaction. (This is a Sale

transaction because only one Delayed Capture transaction is allowed per Authorisation.) For

example:

"TRXTYPE=S&TENDER=C&PWD=x1y2z3&PARTNER=PayPal&VENDOR=SuperMerchant&USER=Sup

erMerchant&O RIGID=VXYZ01234567&AMT=34.00"

RESULT=0&PNREF=VXYZ01234569&AUTHCODE=25TEST&AVSADDR=Y&AVSZIP=N

N OTE: In the case that your business model uses the Authorisation/Delayed Capture cycle for

all transactions, you could have chosen to use an Authorisation/Delayed Capture to

collect the $34 in this example. You would generate the Authorisation for the $34 using

the initial Authorisation as a reference transaction.
