Does PayJunction Support TLS 1.2?

Beginning on June 30, 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 and software applications that make API calls to our systems.

  1. To continue using the PayJunction website (https://www.payjunction.com), merchants must use updated browsers that support TLS 1.2 or higher. 
  2. Software applications that integrate with PayJunction via our API must use TLS 1.2 or higher in order to avoid interruption after June 30, 2018.

What does this mean and how do I fix this?

I use PayJunction.com to process transactions, how does this affect me?

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

I use a software application that integrates with PayJunction to process payments, how does this affect me?

The vast majority of software applications have already updated their product to use TLS 1.2 or higher. If you are uncertain about whether your software application requires an update, then we recommend that you contact the software provider and ask them to confirm that they have updated the software to support TLS 1.2. 

TLS 1.2 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).
