AvaTax API 18.9 Patch Notes

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

Environment URL Release Date
Sandbox https://sandbox-rest.avatax.com 2018-09-11
Production https://rest.avatax.com 2018-09-25

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.

Pagination Improvements

The AvaTax API presents a standard method for pagination using the pattern set out in the Microsoft REST API Guidelines. This standard uses the query string parameters $top and $skip to indicate the number of records you wish to fetch.

All AvaTax APIs enforce a maximum number of records that can be fetched in a single API request. The limit is set at 1,000 records. Your code will receive information about the total number of records detected by your fetch call so that you can display the appropriate pagination information and allow users to browse through records.

The REST API 18.9 release includes more documentation about pagination and standardizes the wording used to be more consistent.

Improvements to Custom Tax Rules

Avalara customers can use the TaxRules API suite to customize the behavior of the tax calculation engine. If you have received custom tax rulings from your auditor, or if your customers have special rules for exemptions, or for many other cases, these tax rules can help ensure that your software works the way your accounting department wants.

This release contains customized error messages and better documentation for common use cases.
