Important: On February 25, 2016, all your merchants' transactions and expired, canceled or terminated ARB subscriptions (and their associated profiles) from 2013 will be permanently archived and no longer accessible in the Merchant Interface.
Authorize.Net retains your merchants' transaction history for a minimum of two years, which is accessible through the search feature of the Merchant Interface. As a standard business practice, we highly recommend that your merchants download and save their online transactions on an annual basis. That way the data will be available for their own records, even after it has been archived.
For detailed information on how to search for and download transactions within a specific date range, please see the Download Transaction File Guide at http://www.authorize.net/files/downloadguide.pdf.
