# FHIR Service URLs for Patient EHI Access

# 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.

### **Base FHIR Service Endpoints**

**FHIR Base URL (R4):**

[https://healthlake.us-east-1.amazonaws.com/datastore/8d8ae0ebc52744d8d9c6af8009bef7e6/r4/](https://healthlake.us-east-1.amazonaws.com/datastore/8d8ae0ebc52744d8d9c6af8009bef7e6/r4/)

This is the primary base URL for accessing FHIR resources such as Patient, Observation, Condition, Encounter, and MedicationRequest.
