October 17, 2019 - TLS (and its predecessor SSL) are cryptographic protocols that provide authentication and data encryption for clients connecting with web servers. As new vulnerabilities are discovered, older cryptographic protocol versions are deprecated to maintain secure environments. On Tuesday, January 21, 2020, Smarty (formerly SmartyStreets) will require clients to use TLSv1. 2 or greater to connect with Smarty APIs without interruption. Clients using TLSv1. 0 or TLSv1. 1 will no longer be able to connect.
