transaction information. CVV2 is needed for card security code validation. For details on card

Submitting Authorisation/Delayed Capture Transactions

An Authorisation (TRXTYPE=A) transaction places a hold on the cardholder’s open-to-buy

limit, lowering the cardholder’s limit by the amount of the transaction. It does not transfer

funds.

A Delayed Capture (TRXTYPE=D) transaction is performed after an Authorisation to capture

the original Authorisation amount. The Delayed Capture is scheduled for settlement during the

next settlement period.

Because Visa and MasterCard regulations prohibit capturing credit card transaction funds until

a product or service has shipped to the buyer, most processing networks implement an

Authorisation transaction followed by a Delayed Capture transaction.

When To Use Authorisation/Delayed Capture Transactions

If your business does not provide immediate fulfillment of products or services, you should

use this two-stage transaction solution, also known as Delayed Capture processing, because it

enables you to capture credit card transaction funds when your are ready to collect them.

N OTE: If you signed up for the PayPal processor with Fraud Protection Services, you must use

delayed capture processing for all sale transactions.

If your business provides immediate fulfillment and you are not using the PayPal processor

with Fraud Protection Services, you can use a simple Sale transaction instead. For details, see

“Submitting Sale Transactions” on page 24. If you need to recharge a credit card and you are

not storing the credit card information in your local database, you can perform a new reference

transaction based on a Sale. For details, see “Submitting Authorisation/Delayed Capture

Transactions” on page 25.

IMPORTANT: Only one Delayed Capture transaction is allowed per Authorisation

transaction.
