Transport Layer Security (TLS) is an encryption protocol used to secure communications over the internet. When you see a lock icon in the address bar of your browser next to a URL that starts withhttps://, the connection uses TLS. TLS applies to all connections to Shopify, including your own connections and your customers’ connections. The most recent version of TLS protocol is TLS 1.2.
On June 20, 2018, Shopify will remove support for TLS versions 1.0 and 1.1 to better protect the data of anyone accessing the FanatikApps website, your storefront, or your admin page. If your browser does not support TLS 1.2, then after June 20, 2018 you will see connection errors when you visit FanatikApps sites.
Customers attempting to access your FanatikApps storefront whose browsers do not support TLS 1.2 will also see connection errors and won’t be able to load your site after June 20, 2018.
If you are an app developer and you want your app to continue to work with FanatikApps after June 20, 2018, then ensure that your applications connect toFanatikApps’s APIusing TLS 1.2. If your app only supports TLS 1.0 or 1.1, then you need to upgrade it to support TLS 1.2.
