The Systemedx FHIR API is based on FHIR Release 3 (STU) Version 3.0. It is a REST based API that can return data in either XML or JSON.

The Systemedx FHIR API uses OAuth 2 for authentication. This requires the use of a Bearer token in the Authorization Header.

The API has patient search functionality with built-in rights management to ensure only authorized individuals can access patient data. To access data you must be a patient, provider, or other EHR user who has been given access rights.
