  title: Canvas Medical SMART on FHIR US Core Retrieval
  summary: Discover server capabilities, locate a patient, then pull the US Core clinical summary - problems, vitals/labs, medications, and allergies.
  description: >-
    The canonical SMART on FHIR read flow against the Canvas FHIR R4 API. The
    CapabilityStatement is fetched first (the SMART App Launch conformance step),
    a patient is located by demographics, read by id, and then the US Core data
    classes are retrieved for that patient: Conditions (problem list),
    Observations (vitals and labs), MedicationRequests, and AllergyIntolerances.
    Every step inlines its request so the flow can be read and executed without
    opening the underlying OpenAPI description.
