What do I need to do to use TLS?

Overview

You want to know if you need to change anything in your configuration to use TLS rather than SSL.

Environment

AvaTax Integrations

Resolution

  • Avalara's connectors are equipped to auto-negotiate using TLS.  You don't need to change anything in your systems in order to use a TLS connector.
    • The primary AvaTax endpoint supports TLS 1.2, 1.1, and 1.0
    • If your connector supports TLS 1.2 they should be able to negotiate over security protocol without any issues
    • As of April 2016 there are no plans to disable TLS 1.0 support on the AvaTax endpoints
