  title: Medblocks Connections API
  version: '2026-04-25'
  description: 'Developer API for the Medblocks Platform.


    Connect any patient to one or more EHRs (Epic, Cerner, Athena, …) via a single hosted PatientSession, then pull their unified FHIR records through this API. Server-to-server only — no browser-side calls. Authenticate every request with a Bearer secret key.


    **Resources:** `PatientSession`, `Patient`, `Connection`, `FhirSource`. **Conventions:** date-pinned versioning (optional `Version` header), a typed error envelope on every non-2xx response.'
