Does PayJunction Support TLS 1.2?

PayJunction has supported TLS 1.2 for years.

Beginning on June 1st, 2018, in accordance with PCI security guidelines, PayJunction will require the use of TLS 1.2 while establishing connections to our website at PayJunction.com.

This will impact traffic using old web browsers (as well as old code that makes API calls to our systems).

Therefore, merchants that are using older browsers that do not support TLS 1.2 or higher will not be able to access our website.

What does this mean and how do I fix this?

The simple answer is use an up-to-date modern web browser (i.e. latest versions of Internet Explorer, Chrome, Firefox, Safari, or Edge).

We highly recommend that all businesses update their internet browsers to the latest version in order to ensure support for TLS 1.2.

Below is a list of popular browsers and the versions that support TLS 1.2:

Minimum Required Browser Versions

  • Microsoft Internet Explorer: version 11 and above
  • Microsoft Edge: version 12 and above
  • Google Chrome: version 30 and above
  • Apple Safari: version 8.9 and above
  • Mozilla Firefox: version 34 and above
  • Opera Browser: version 20 and above

TLS 1.2 Also Required for Development (PayJunctionLabs.com)

As of June 17, 2016, TLS 1.2 is required in order to establish an API connection and in order to login to the test account at PayJunctionLabs.com.

If you are receiving TLS/SSL errors when attempting to reach payjunctionlabs.com, please ensure that the code running on your server and/or browser supports TSL 1.2 or greater.

June 1st, 2018 will be the deadline for all API connections to use TLS 1.2 when connecting to all production systems at PayJunction.com.

TLS Fallback Prevention

If a connection is established with TLS 1.2, then nothing will allow that connection to be downgraded to an earlier version of TLS (provided your code or browser also supports TLS fallback prevention)

Thus, you can ensure that your connection is only using TLS 1.2 by making sure your system supports TLS 1.2 with fallback prevention (regardless of other customer connections to PayJunction).
