  title: Medplum Schedule Encounter
  summary: Create a Practitioner, create an Encounter linking the patient and practitioner, then read it back.
  description: >-
    Models the start of a clinical visit. The workflow creates a Practitioner
    resource, then creates an Encounter that references both an existing Patient
    (the subject) and the new Practitioner (a participant), and finally reads the
    Encounter back to confirm its status. Every step spells out its FHIR request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.
