PayPal will stop working on 30th of June and merchants will be unable to accept payments if they’ve not updated their websites to the latest standards which includes an upgrade to TLS.
The deadline for merchants to upgrade to Transport Layer Security (TLS) 1.2 June 30, 2018 and PayPal are requiring all merchants to upgrade their security protocols to TLS 1.2, in line with the requirements set by the Payment Card Industry (PCI) Council. The TLS protocol is used to encrypt communications between your platform and PayPal’s servers.
What do you need to do to upgrade to TLS?
Merchants should verify whether their website supports TLS 1.2 and, if necessary, make appropriate updates.
If you have a hosted service
Contact your provider to ensure they support TLS 1.2 and HTTP/1.1
Does your system already support TLS 1.2 and HTTP/1.1?
If the answer is yes then you’re all set. If not, then you need to upgrade to TLS 1.2 and HTTP/1.1 before the 30th of June.
Have you hard coded an earlier version of TLS or HTTP?
Update your code to always use the latest version of TLS and HTTP supported by PayPal endpoints.
