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