Integration
FHIR (Fast Healthcare Interoperability Resources)
FHIR (Fast Healthcare Interoperability Resources) is the HL7 standard for exchanging healthcare data through web APIs. Modern AI integrations with EHRs read patient data through FHIR endpoints, which return structured resources (Patient, Encounter, Observation, MedicationRequest) in JSON. FHIR is the default integration layer for healthcare AI in 2026 — deployments that hand-roll EHR integration outside FHIR are doing avoidable work.
