Leveraging the payments community to make subscriptions unstoppable
Adyen merchants must upgrade their communication with the live Adyen platform to support TLS 1.2 by February 19th 2018.
Early TLS (TLS 1.0 / TLS 1.1) has known weaknesses and therefore does not provide sufficient security.
We recommend the use of TLS 1.2 to safeguard sensitive cardholder data during transmission over open, public networks such as the internet.
TLS 1.2 connectivity has been available for some time and earlier TLS versions will be disabled in two phases:
September 25th 2017 - Early TLS disabled on Adyen’s Test platform / February 19th 2018 – Early TLS disabled on Adyen’s Live platform
We encourage scheduling the upgrade as soon as possible to adhere to industry best practices.
Merchants should upgrade server-to-server and modification requests notifications to use TLS 1.2 on February 19th 2018.
Direct API Merchants and Client Side Encryption (CSE) Merchants using early TLS versions need to upgrade their systems to connect to the Adyen platform using TLS 1.2.
Merchants using Adyen’s POS solution may need to upgrade their firmware and/or library versions to support TLS 1.2.
As a general guideline:
Merchants with Hosted Payment Page integrations do not need to make further changes if server-to-server notifications and modifications requests use TLS 1.2.
