Notice: Effective May 1st, 2014, access to the HIW web services API will require the use of an API key. Please request an API key if you haven’t done so already. In addition to this requirement, prior versions of the services (v3 and v4) will be deprecated and will no longer be accessible. All API calls must use the v5 URL shown below and include an API key as described here.

The Health Indicators Warehouse provides access to the underlying data through the use of an Application Programming Interface (API) which is designed to present information to systems with disparate architectures and technologies. The API exposes two distinct web services; a RESTful service and a SOAP-based service to provide access to the data.
