Welcome to the Health Chain Developer Portal! The portal provides access to Health Chain's APIs, which are based on the Health Level 7® (HL7) Fast Healthcare Interoperability Resources (FHIR®) 4.0.1 standards.
The Provider Directory API facilitates searches for Health Chain Medicare Advantage and US Commercial in-network California providers. Note: The inclusion of the US Commercial California Plans will include all network contracted providers for any in-scope CA Plan and will be effective on February 28, 2024.
You'll find several resources on the portal to help you create your applications. How to Connect topics that provide steps on how to get your application connected to the Health Chain FHIR server; and Implementation Guides, which provide information on the how the FHIR spec is implemented, along with interactive access to the API so you can try it out within your browser.
