AvaTax API 19.6 Patch Notes

This article is about the June 2019 monthly update to the AvaTax API.

Sandbox testing window

The AvaTax release schedule includes a preview period during which time the latest software is available for integration testing in the AvaTax Sandbox Environment two weeks before launching to production. If your engineering team would like a sandbox account for integration testing purposes:

• Development and Solutions Partners (DSP), please contact your Business Development Manager.
• Avalara customers, please contact your Customer Account Manager or open a support ticket.

Partner Integration Certification API

If you write an integration with Avalara APIs, this API will be your friend. It tests 17 scenarios to give you a detailed examination of your integration completeness. When a scenario examination has failed, the API returns a detailed message explaining why. It's important to continue testing this API throughout the development of an integration, until the endpoint returns a Success tag. 

Multi-Tax enablement in TaxContent API

Previously, Tax Content API only supported SalesAndUse tax type scenarios. In this release, we’re enabling Multi-Tax content into API results so partners can trigger UnitOfBasis, TaxSubType, and Parameters results with Item-included TaxContent API calls. And in the next release, we’ll enable TaxApplicationLevel results that indicate whether a TaxOnTax calculation has occurred.
