REST API Makes AvaTax Integration Easy

With any third party integration two things are absolutely essential – an easy and reliable API platform, and knowledgeable, responsive tech staff to help with the integration.  I’m glad to say, Avalara’s AvaTax REST system provides both! -Early integrator

AvaTax gives you fast and up-to-date sales tax calculation based on geo-location (which kicks ZIP code calculation’s ass). So you get the most accurate sales tax calculation possible anywhere in the 11,000+ North American tax jurisdictions.

Our REST API provides the power of Avalara’s calculation engine to your application. Three advantages of using our REST API, which supports both JSON and XML message formats:

  • Quick and flexible interface
  • Code easily with query strings
  • No need for internal server

Here is a get sample:,-122.51702/get.jsonp?saleamount=1

Here is the return:

AvaTaxResponse(/* json result */)

(see more documentation)

Easy as that. Plus this integration also allows your business to leverage our powerful Certificate and Return management tools. But this is not just about our REST API integration. This is about you and what you need from our service. Any comments or questions? Leave them below.
