Overview of the HIW Web Services

API

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 Health Indicators Warehouse API exposes two distinct web services; a RESTful service and a SOAP-based service to provide access to the data. The methods required to access the underlying services are documented in the Service Methods and Service Types pages.
