Web Services

What are Web Services?
Web Services provide you with direct access to the Kansas Department of Revenue's technology platform. Using the Web Service we provide, you can access Sales tax rate data using address and/or zip code information and tie the data into your shopping cart checkout process or accounting system in real time.

How do I use KDOR's Web Services?

  1. Create a free retailer account.
  2. Download the WSDL (Web Service Description Language) from the secured retailer account area (available after creating your account). A WSDL is a document written in XML which describes a Web service. It specifies the location of the service and the operations (or methods) the service exposes.
  3. Integrate KDOR's Web Service into your existing application. To do this, you must be familiar with the code your shopping cart is written in, and also the code must be modifiable.

Boundary and Rate Tables

IMPORTANT: Beginning with Jan. 2009, the boundary file addresses will no longer be consolidated. This means that the file will now contain 500,000+ records and will be in a zip archive with the rate file. You will need a tool such as WinZip or WinRar to access the files.
