As of May 31, 2013, the HIW team will be archiving older versions (Versions 1 and 2) of its APIs for RESTful and SOAP services. Please update your API code to access Version 3 as needed. The base URLs for the Version 3 services can be found at http://www.healthindicators.gov/Developers/Overview. Changes and updates include addressing adding FIPS codes to web service results, and exposing several additional service methods based on foreign keys and unique indices. We also anticipate releasing Version 4, which will have a new data model, in the coming weeks. More details to follow as well as complete API release notes. Contact us at HealthIndicators@cdc.gov with any technical or other HIW questions.
