FAQ: Register as a Developer (OnyxOs)

Q: What can I access when I have registered as an OnyxOS developer?

OnyxOs supports a growing number of HL7 FHIR Implementation Guides. We provide the APIs that are defined in the Capability Statements provided by the guides. These APIs are therefore available via the OnyxOs Developer Sandbox.

Onyx is also working with a growing number of Health Plans to support their compliance with the CMS Interoperability and Patient Access Rule. As these Health Plans go live, as a Registered OnyxOS Developer, you will be able to request access to the production FHIR APIs of those Health Plans.
