AvaTax API 17.12 Patch Notes
This article is about the December 2017 monthly update to the AvaTax API.
During the months since the 17.9 Patch Notes, our team has been hard at work tuning the performance of AvaTax for the once-a-year sales events that happen in November. Here’s a summary of the improvements that have been made since the September release:
- Reduced the impact of calling the GetTransactionByCode API and GetTransactionByTypeAndCode API. This change improved performance for customers whose products used a mix of calls to these APIs alongside creating new transactions.
- Eliminated caching delays caused by updating user credentials or license keys rapidly before they had time to propagate through the AvaTax storage cluster.
- Enforced a limitation on the ListTransactionsByCompany API to avoid extremely long timeouts for customers with a large number of transactions. By default, this API now limits you to fetching data within the current 30-day window.
- Better query optimization when fetching data from our data store, and better use of our three-tiered data caching strategy throughout the REST API.
- Improved performance for the free TaxRatesByPostalCode API.
These changes were released gradually during the October and November timeframe as our team prepared for Black Friday and Cyber Monday sales events.
MultiDocument API Suite
Are you building a marketplace website that provides the ability for a wide variety of vendors to list their wares? Does your company make purchases for multiple business entities with a single transaction? If so, you may be a candidate for Avalara’s newest API: the MultiDocument API Suite.
This collection of APIs makes it convenient to record a transaction for a variety of vendors in one place, and to automatically break up the transaction so that it can be reported on multiple separate tax returns, one per business entity. We’ll update our documentation for this feature and share with you a variety of blog posts explaining how this API suite can help you create, track, adjust, and reconcile transactions in a multi-vendor marketplace.
Support for Country and Region Naming
As of the December release of AvaTax, all of our APIs now allow you to specify full length country names, abbreviations, and even some common misspellings of various countries. We have subscribed to the International Standards Organization’s ISO3166 database, which provides us with official names and abbreviations of countries and region codes throughout the world and in many popular languages.
Now that you are able to use fully spelled out names of countries and regions in all AvaTax APIs, here are a few examples:
- You can now use UNITED STATES as well as US when referring to the United States.
- You can now use CALIFORNIA as well as CA when referring to the west coast state.
- You can now use ZURICH or ZÜRICH as well as ZH when referring to the region within Switzerland. Character accents are optional, but supported.
- You can now use GERMANY or DEUTSCHLAND or ALLEMAGNE as well as DE to refer to the Republic of Germany. The same country name is available in certain formally recognized linguistic variants.
Changes to CreateTransaction
A variety of improvements and bugfixes have been made to the CreateTransaction API.
- If you omit the field
datewhen calling the CreateTransaction API, you will now get a proper error message indicating that the field cannot be null or empty.
- For consistency, the field
customerUsageTypeis being replaced with
entityUseCode. We have chosen to standardize on the naming of this field all throughout our API; so please expect to see the same field have the same name in all instances.
