Shopify is Deprecating its Support of TLS 1.0 and 1.1
Update June 1st 5:10pm EDT
Update; We will be extending the deadline, TLS 1.0 and 1.1 should be able to connect again. I will share more information when I have a specific date. However, this date will be before June 30th 2018, as that is the global deprecation date, after which you will not be PCI Compliant.
The extended deadline is June 20th, 2018.
As part of our commitment to providing a safe and secure platform, as of May 31, 2018, Shopify will be halting support for outdated TLS 1.0 and 1.1 security protocols.
Why is Shopify making this change?
This update is being made in accordance with new regulations set by the Payment Card Industry Data Security Standard (PCI). To read the official statement from PCI on TLS 1.0, click here.
What action am I required to make?
In order for your app to continue to be function on Shopify, you will need to ensure that your applications are able to connect with our APIs using TLS 1.2. If your app only supports TLS 1.0 or 1.1, you will need to upgrade it to 1.2 by May 31st, 2018.
