FHIR Router

The FHIR Router dispatches incoming REST interactions — read, search, create — to the appropriate handler and shapes responses per FHIR R4 rules.

Thin routing layer

Authentication and consent run before the router hands off to handlers — it never touches Clinical Data directly.

Responsibilities

Maps URLs and verbs to internal handlers (Patient, Observation, Encounter, …).
Applies pagination and _summary rules for search sets.
Invokes SMART Auth Filter and Consent Check before handlers touch Clinical Data.
