Performing Credit Card Transactions

Submitting Authorisation/Delayed Capture Transactions

The return data for an Authorisation transaction is the same as for a Sale transaction. To

capture the authorised funds, perform a Delayed Capture transaction that includes the value

returned for PNREF, as described in Step 2 on page 27.

EXAMPLE 3.1 Example Authorisation Transaction Parameter String

Issue Authorisation-only Transaction

"TRXTYPE=A&TENDER=C&PWD=x1y2z3&PARTNER=PayPal

&VENDOR=SuperMerchant&USER=SuperMerchant&ACCT=5555555555554444&EXPDATE=0308

&AMT=123.00&COMMENT1=Second purchase

&COMMENT2=Low risk customer&INVNUM=123456789&STREET=5199 MAPLE&ZIP=94588"

XAMPLE 3.2 Example Authorisation Response

(Response parameters are described in detail in Chapter 4, “Responses to Credit Card

Transaction Requests”)

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

&AVSADDR=Y&AVSZIP=N

Step 2 Perform the Delayed Capture transaction

Set ORIGID to the PNREF value returned in the original Authorisation transaction response

string. (There is no need to retransmit the credit card or billing address information—it is

stored at PayPal.)

If the capture succeeds, the amount of the Capture is transferred to the merchant’s account

during the daily settlement process. If the capture does not succeed, the hold on the

cardholder’s open-to-buy is still in effect.

EXAMPLE 3.3 Example Delayed Capture Transaction Parameter String

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

&USER=SuperMerchant&ORIGID=VXYZ00887892"

XAMPLE 3.4 Example Delayed Capture Response

RESULT=0&PNREF=VXYZ00895642&AUTHCODE=25TEST&AVSADDR=Y&AVSZIP=N

Delayed Capture Transaction: Capturing Transactions for Lower Amounts

You can perform a Delayed Capture transaction for an amount lower than the original

Authorisation amount (useful, for example, when you make a partial shipment).

Delayed Capture Transaction: Capturing Transactions for Higher Amounts

You can perform a Delayed Capture transaction for an amount higher than the original

Authorisation amount, however, you are charged for an extra transaction. In addition, the

cardholder’s open-to-buy is reduced by the sum of the original Authorisation-only amount and

the final Delayed Capture amount.
