API - Send Vital Signs
This API sends the vital signs readings of the patient
Scope
This transaction involves the requestor sending a POST request to the FHIR service to submit an Observation resource. The request is received by the FHIR Service that extracts and assemble the vital signs readings as per the RCM HL7 FHIR Implementation Guide specification and creates the record.
Upon successful creation, the FHIR Service returns an HTTP response code (i.e 2xx) and the same Observation resource, together with the observation id.
For unsuccessful creation, the FHIR Service returns an HTTP response code (i.e 4xx or 5xx) and an OperationOutcome resource.
