Overview

An example. Note the username as a parameter and transaction key you will want to use later. The amount that you pass in will be rounded, so preferably pass in X.2 decimal so that no rounding occurs. It is rounded because if it looks like 00.000 Authorize.Net fails the transaction as incorrectly formatted.
