AvaTax API 18.12 Patch Notes

This article is about the December 2018 monthly update to the AvaTax API.

Environment URL Release Date
Sandbox https://sandbox-rest.avatax.com 2018-12-26
Production https://rest.avatax.com 2019-01-07

Sandbox Testing Window

The AvaTax release schedule includes a preview period where 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, please contact your account manager or open a support ticket.

Advanced Items Setup

In addition to existing basic configurations for Items, we are now allowing more advanced settings, including:

Items can be tagged into multiple classification systems. As opposed to Avalara tax code being the only way of classifying your item, we are now supporting more than 100 classification systems recognized worldwide, including HTS, TARIC, etc. We are also continuing supporting Avalara Tax Code with a system code of AVATAXCODE.

Items can be set up with parameters, which were previously only allowed in transactions. Calling CreateTransaction with a pre-configured item with parameters will allow your transaction request a lot cleaner.

Definition APIs in supporting configuring Items

In assisting setting up your items to facilitate your transactions, we are providing a suite of new definition APIs:

ListParametersByItem is similar to the existing ListParameters, but provides you the more refined result set that are relevant to your profile setup (service subscriptions, nexus configuration and items).

ListProductClassificationSystems provides all classification systems recognized by Avalara.

ListProductClassificationSystemsByCompany is similar to the API above, but returns the more refined result set that are relevant to your profile setup (nexus configurations).

Swagger loading time is improved

We improved Swagger loading time by pre-compiling the swagger.json file and cached it in memory.
