# Firely Server FHIR REST API

**Canonical:** https://apis.io/apis/firely-server/firely-server-fhir-rest-api/  
**Provider:** Firely — https://apis.io/providers/firely-server/  
**Documentation:** https://docs.fire.ly/projects/Firely-Server/

Firely Server FHIR REST API is one of 3 APIs that [Firely](https://apis.io/providers/firely-server/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include FHIR, REST, Healthcare, CRUD, and Search. The published artifact set on APIs.io includes API documentation.

Every Firely Server (formerly Vonk) instance exposes the standard HL7 FHIR REST API contract — type-level and instance-level CRUD, search, history, batch/transaction, capability statement (/metadata), conditional operations, and conformance-driven validation — plus pluggable modules for Terminology Services, Bulk Data Access ($export), SMART on FHIR, CDS Hooks, Subscriptions/PubSub, FHIR Mapping Language, and custom search parameters. Firely Server supports FHIR R4, R4B, R5, and STU3 across MongoDB and SQL Server backends and is G10, ONC, and ISiK certified. The API contract is the HL7 FHIR specification itself; there is no public hosted multi-tenant base URL — customers self-host Firely Server on Windows, Linux, macOS, Docker, or Kubernetes.
