FHIR API Development Services
Build ONC-compliant FHIR R4 APIs, SMART on FHIR applications, and scalable healthcare interoperability platforms with our certified FHIR development team.
What We Do
From FHIR server architecture to ONC certification — our team delivers every layer of your FHIR implementation.
FHIR R4 Server Development
We build fully conformant FHIR R4 servers using HAPI FHIR, Microsoft Azure Health Data Services, Google Cloud Healthcare API, or custom implementations — tailored to your use case.
SMART on FHIR Authorization
We implement SMART on FHIR app launch and authorization flows — both standalone and EHR launch — using OAuth 2.0 and PKCE for secure, standards-compliant app access.
US Core & Da Vinci Implementation
We implement US Core, Da Vinci PDex, CRD, DTR, and other critical implementation guides required for ONC compliance, CMS interoperability, and prior authorization workflows.
Bulk FHIR & Analytics Exports
We implement FHIR Bulk Data Access (Flat FHIR) for large-scale data exports — supporting population health analytics, payer-provider data exchange, and regulatory reporting.
How It Works
Our FHIR development process is designed for compliance, performance, and long-term maintainability.
FHIR Capability Assessment
We assess your systems, data model, and regulatory requirements to define the right FHIR architecture and implementation guide scope.
FHIR Server & API Build
Our engineers build your FHIR server, resource endpoints, search parameters, and authorization layer to specification.
Conformance Testing
We validate your FHIR implementation against Touchstone, the Inferno test suite (ONC), and your target EHR's certification requirements.
Production Deployment & Support
We deploy to your cloud infrastructure, monitor API health and performance, and provide ongoing maintenance and support.
Why Choose Our FHIR Team
ONC/CMS Compliance Ready
Our FHIR implementations are built to meet ONC Final Rule, CMS Interoperability Rule, and CMS prior authorization requirements — including Inferno test suite validation.
EHR-Connected from Day One
We have direct experience integrating FHIR APIs with Epic open.epic.com, Cerner fhir.cerner.com, and other major EHR FHIR endpoints.
Cloud-Native Architecture
We build FHIR solutions on Azure Health Data Services, Google Cloud Healthcare API, AWS HealthLake, or self-hosted HAPI FHIR — based on your infrastructure preference.
Frequently Asked Questions
What FHIR version do you develop for?
Our primary focus is FHIR R4, which is required by ONC, CMS, and all major EHR vendor FHIR APIs. We also support FHIR R3 (DSTU3) for legacy integrations and FHIR R5 for forward-looking implementations.
Can you help us pass the ONC Inferno test suite?
Yes. We have experience preparing FHIR implementations for the ONC Inferno certification test suite, including US Core profile conformance, SMART on FHIR authorization, and Bulk Data Access testing.
Do you build FHIR client applications as well as servers?
Absolutely. We build both FHIR servers (exposing FHIR APIs) and FHIR client applications (consuming FHIR APIs from Epic, Cerner, or other sources) — as well as full FHIR integration pipelines.
