Performing Direct Payment Credit Card Transactions
Submitting Authorization/Delayed Capture Transactions
4
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
Authorization transaction followed by a Delayed Capture transaction.
When To Use Authorization/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.
If your business provides immediate fulfillment, you can use a simple Sale transaction instead.
For details, see “Submitting Sale Transactions” on page 23. 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 “Recharging to the Same
Credit Card (Reference Transactions)” on page 32.
