Another service provider (Authorize.Net) will be “flipping the switch” to require TLS v1.2 on Feb 28, 2018.  When that occurs, older versions of ShopSite (v12 sp2 r3 and earlier) will no longer be able to communicate with Authorize.Net for credit card processing.  Authorize.Net is one of the larger payment gateways so this switchover could affect a number of merchants.

What Version Am I Running?

To see what version of ShopSite you are running, log in to ShopSite and look at the footer. If you see “12 sp2 r4” or greater, you are good to go.  The current release of ShopSite at the time of this post is version 14.0.  Here’s what it looks like in version 12 at the bottom lower left of the screen.

This store would need to upgrade since it is running version 12 sp2 r2.3

Other Services Affected by TLS 1.2?

Beside Authorize.Net, First Data and UPS have recently made the switch over.  The next big payment gateway to make the switch is probably PayPal.  They are currently scheduled to switch on June 30, 2018.  View this kbase article to see what other service providers have announced switchover dates.  Since the PCI (Payment Card Industry) deadline is June 30, 2018, everyone will be requiring TLS 1.1 or 1.2 by then.
