Can I whitelist a singular IP to access the AvaTax web service?

Overview

Using an external facing web portal to leverage the AvaTax service.

Environment

AvaTax SOAP API

AvaTax REST API

Resolution

No whitelisting should be needed to send information to AvaTax.  Depending on your network set up, you may need to whitelist the AvaTax URL that corresponds with the environment that you are using:
 

AvaTax Production:  https://avatax.avalara.net
AvaTax Development:  https://development.avalara.net

 

To determine if any whitelisting is needed for inbound traffic, you will want to consult with your IT department.
