Avalara provides two different ways of accessing their tax calculation tools: SOAP and REST APIs.
Currently SOAP(Legacy) is their most extensively supported form of tax calculation. While REST is less extensive, it still provides much of what SOAP will.
SOAP is configured as the default mechanism for calculating taxes with the Broadleaf Avalara Tax Module.
