FHIR Service URLs for Patient EHI Access #
Overview #
LegendEHR provides standardized HL7® FHIR® R4 (Fast Healthcare Interoperability Resources) endpoints to allow patients and authorized third-party applications to securely access their Electronic Health Information (EHI).
All endpoints use HTTPS (TLS 1.2 or higher) and SMART on FHIR–based OAuth 2.0 authorization through AWS Cognito.
