  "id": "388a86c8-2544-46d6-bcdb-289627ce5afb",
  "type": "message",
  "timestamp": "2022-11-01T09:21:11.764Z",
  "entry": [
      "fullUrl": "urn:uuid:f80930be-add3-4e35-89d5-7b0e3f08e868",
      "resource": {
        "resourceType": "MessageHeader",
        "id": "f80930be-add3-4e35-89d5-7b0e3f08e868",
        "event": {
          "code": "|example",
          "system": ""
      "fullUrl": "",
      "resource": {
        "resourceType": "Patient",
        "id": "12345",
