Transaction Types

The following paragraphs describe the transaction types.

Typically if products are shipped within 24 hours, a Sale transaction can be used. If the ship cycle is longer, an Auth should be used initially, and a Post Auth transaction issued after the product is shipped.

A Sale transaction will authorize the amount of the sale and capture the funds providing the authorization is approved. A Sale transaction is the equivalent of running an Authorization and then running a Post Authorization moments later.

An Authorization transaction will lower a cardholder s right to buy by the amount specified, and reserve that amount for the merchant. The amount will remain reserved for approximately seven days, at which time the card-issuing bank will release it. In order to capture the cardholder's funds, you must run a Post Authorization transaction within the seven-day window to settle the transaction.

A Post Authorization is used to capture funds from a previously obtained authorization, either electronically or by voice. If the authorization was obtained electronically, you must pass the original authorization number, and original invoice number of the authorization transaction. If the authorization was obtained through a voice authorization it is not necessary to pass an invoice number.

A Credit transaction credits money back to a cardholder's account. To reverse a sale that took place on or before the previous day's business, execute or run a credit transaction to give back the cardholder all or part of the funds captured in the original sale.

A Void transaction voids any Sale, Post Authorization, or Credit transaction that was submitted successfully on the same business day that the Void transaction was submitted. If the Sale or Post Authorization was processed during the previous day's business, then you must perform a Credit transaction to credit the cardholder's account. If you are attempting to reverse a credit that took place during a previous day's business, you must run a Sale transaction that will debit the cardholder's account and offset the credit.
