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.

Throttling on DownloadReport API

DownloadReport API is an endpoint that can utilize significant server memory. In 19.8, we’re adding throttling control to this endpoint to prevent its impact on service stability. If receive a response of “429 – Too many requests” from this endpoint, please be aware that it’s due to the new throttling mechanism we’ve added.

Multiple Exemption API enhancements

We’ve refined our Exemption APIs in multiple areas:

  • EcmsId has been added the Certificate model to indicate whether the Exemption Certificate has taken effect on exempting transactions
  • Attributes have been enabled for Customers through the newly created ListAttributesForCustomer API, LinkAttributesToCustomer API, and UnlinkAttributesFromCustomer API
  • DocumentExists field has been added to the Certificate model to flag whether a PDF has been created for the file uploaded
  • PoNumber can now be updated in the UpdateCertificate API

Reflecting origin name in Access-Control-Allow-Origin header

In our 19.5 Patch Notes, we talked about adding the new Access-Control-Allow-Origin header to our API response to enhance client-side security with browser usage. This header was initially introduced in “permissive” mode, so it wouldn’t prevent client side from displaying API content across domains. In this release, we switched from “permissive” mode to “restrictive” mode, so that after the change, only registered websites will be able to build UI to display Avalara content.

If you have a use case to serve Avalara API response directly into your client’s browser, please contact us so we can work with you on registering your domain name.
