CharmHealth FHIR API

CharmHealth EHR FHIR API conforms to FHIR R4 (4.0.1) and the US Core STU 3.1.1 Implementation Guide. It supports 30+ FHIR resources covering clinical (AllergyIntolerance, Condition, Procedure, Immunization, MedicationRequest), care coordination (CarePlan, CareTeam, Goal, Encounter), administrative (Patient, Practitioner, Organization, Location, Appointment), diagnostic (DiagnosticReport, Observation), and documentation resources (DocumentReference, QuestionnaireResponse, Provenance). Authentication uses SMART on FHIR with OAuth 2.0 authorization code flow, PKCE for public clients, and JWT-assertion backend services authorization for system access.
