Transport Layer Security (TLS) is a cryptographic protocol used to provide encryption over a network. You may already be familiar with Secure Sockets Layer (SSL), the predecessor to TLS. When you visit a web page and see 'HTTPS' in the URL, that indicates that the web page is sent over an encrypted connection.

Our REST and SOAP APIs use the same methods of encryption. TLS 1.2 is the latest version of TLS and has been around for ~10 years. It's well supported in web browsers and modern operating systems. TLS 1.2 represents the industry benchmark for encryption and will ensure the highest level of security for your data.
