PayPal will stop working on the 30th of June if merchants haven’t updated their websites to the latest standards. These new standards include an upgrade to Transport Layer Security (TLS). Merchants will, if not updated, not be able to accept payments any longer.
The deadline for merchants to upgrade to TLS 1.2 is June 30th, 2018. PayPal is requiring all merchants to upgrade their security protocol to TLS 1.2, in line with recent requirements set by the Payment Card Industry Council (PCI). This protocol is used to encrypt communications between the PayPal servers and a merchant’s platform. To upgrade to TLS 1.2, merchants should verify whether their website supports TLS 1.2, or perform the necessary updates.
