          {
              "resourceType": "Bundle",
              "type":"transaction",
              "entry":[
                  {
                      "resource":{
                          "resourceType": "Patient",
                          "name":[{
                              "given": ["Johnathan Wick"],
                              "family": "Doe"
                          }],
                          "identifier":[{

                      },
                      "request": {
                          "method": "PUT",
                          "url":"Patient?identifier=dont-kill-my-dog"

                      "fullUrl": "urn:uuid:f9b53a03-cdea-4d61-8ec3-99fffd5cc6ab"

                  },
                  {

                          "code": {
                              "text": "Heart Rate"
                          },
                          "valueQuantity": {
                              "value": 72,
                              "unit": "beats/minute"
                          },
                          "subject": {
                              "reference": "Patient/urn:uuid:f9b53a03-cdea-4d61-8ec3-99fffd5cc6ab"
                          }
                      },
                      "request": {
                          "method": "POST"
                      }
                  },
                  {
                      "request":{
                          "method":"GET",
                          "url":"Patient?identifier=dont-kill-my-dog"
                      }
                  }
              ]

          }   

3. In the given Payload the Patient Johnathan Wick with Identifier dont-kill-my-dog will be created if he does not exist along with the Observation referenced to him. If he already exists in the database, only the Observation will be created referenced to him.
