Pre-Authorization

Overview

The pre-authorization command temporarily places a hold on a specific amount on a credit card before the final amount is known. Once the final amount is determined, you can submit a pre-authorization completion request using that amount and the transactionId of the original pre-authorization. To learn how to execute a pre-authorization completion request, visit Pre-Authorization Completion Command.
