Important Message - System Changes may be Required

What’s changing?

NAB Transact is upgrading the protocols used (TLS 1.0 and 1.1) to secure all external connections made to our systems and enforcing mandatory TLS 1.2 communication from early next year (date yet to be confirmed). This means all merchant API communications with NAB Transact will need to use TLS 1.2 from this date. 


NOTE: TLS versions 1.0 and 1.1 will not work after the change.


What do I need to do?

Checklist: Preparing for the system upgrade to TLS 1.2


- If your website is hosted, check with your hosting provider if they support TLS 1.2

- If you host your own website, check if your system already supports TLS 1.2

- If you or your hosted environment do not support TLS 1.2, arrange/request an upgrade

- Code your system to always use the highest version of TLS available; avoid hardcoding versions


Update your Production Environment to support TLS 1.2


You will need to verify and if necessary, update your production environment to ensure it supports TLS 1.2 November 21st, 2017.


Note: NAB Transact’s test/demo environment was upgraded to TLS 1.2 in May 2017, so you can begin your integration testing well in advance.
