  title: Medplum FHIR Resource CRUD
  summary: Create a FHIR R4 resource, read it back by id, update it, then search the resource type for it.
  description: >-
    A generic FHIR RESTful API lifecycle against the Medplum FHIR R4 backend. A
    resource of any type is created with the generic resource-type create
    operation, read back by id, updated by id, and finally located through a
    type-level search. This exercises the core HL7 FHIR R4 create, read, update,
    and search interactions that underpin US Core and any other FHIR profile.
    Every step inlines its request so the flow is self-contained.
