This article explains how Amazon HealthLake now supports SMART on FHIR 1.0.0, enabling secure interoperability between healthcare applications and patient data through standardized authorization frameworks.

• SMART on FHIR enables developers to build applications once for multiple healthcare systems
• Supports four use cases: standalone/EHR-launched patient and provider applications
• Authorization workflow involves discovery, authorization request, code exchange, token validation, and refresh
• HealthLake requires Lambda function for token introspection and IdP configuration during datastore creation
• Configuration includes authorization strategy, metadata storage, and fine-grained authorization settings
• Benefits include improved interoperability, patient engagement, clinical workflow customization, and developer innovation

SMART on FHIR support in HealthLake enables healthcare providers to integrate third-party applications securely while giving patients controlled access to their health data through standardized protocols.
