Zus stores data in our operational data store according to the Fast Healthcare Interoperability Resources Release 4 (FHIR R4) specification, maintained by the HL7 organization (HL7). We offer a robust FHIR REST API, as detailed in our API Reference.

Authentication

The Zus FHIR REST APIs support the same HTTP Authorization token used throughout Zus APIs. See Authenticating for API Access for instructions on obtaining a bearer token.
