Recently Amazon has made some changes to their API that will affect users that have integrated with Amazon in Acctivate. In reference to this, Amazon may have sent you an email asking you if your company still plans on making calls/connection to the older version and mention a deadline of February 28th, 2017 to make the change.
To make sure you’re up to date by that deadline, simply download and install the 10.2 update for Acctivate. This will not only bring Acctivate up to date, but it will also put you in right standing with Amazon’s new API.
You can download the preview version of Acctivate 10.2 on this page.
