Sales

A sale is a bundled authorization and capture. Some processors and acquirers require a sale transaction instead of using separate authorization and capture requests.
For other processors and acquirers, you can
 request a sale instead of a separate authorization and capture when you provide the goods or services immediately after taking an order.
There are two types of sale processing: dual-message processing and single-message processing.

Single-Message Processing

Single-message processing treats the authorization and capture as a single transaction. There are important differences between dual-message processing and single-message processing:
  • Single-message processing treats the request as a full-financial transaction, and with a successful transaction, funds are immediately transferred from the customer account to the merchant account.
  • Authorization and capture amounts must be the same.
  • Some features cannot be used with single-message processing.
