title: What is difference between Authorize.Net AIM line item and description
body: <p>I'm not sure what the difference between <code>description</code> and <code>lineitem</code>. Is line item a comma separated list of the products bought? I would like to know the variables max length and data type. Also, like to know what field appears in users credit card statement, description or lineitem. Cant find any good documentation.</p>
