You want to know if you need to change anything in your configuration to use Transport Layer Security (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.
- NOTE: Apple, Google, Microsoft and Mozilla will disable Transport Layer Security (TLS) 1.0 and 1.1 support in their respective browsers in the first half of 2020.
- The primary AvaTax endpoint supports TLS 1.2, 1.1, and 1.0 (1.1 and 1.0 until deprecation in first half of 2020).
- If your connector supports TLS 1.2 they should be able to negotiate over security protocol without any issues. Please use TLS 1.2 as your default.
