FHIR Integration & API Development
HL7 FHIR is the standard modern healthcare data exchange is built on. We design, build, and maintain FHIR R4/R5 APIs, SMART on FHIR applications, and EHR integrations that connect your product to Epic, Oracle Health, athenahealth, and the wider healthcare ecosystem — securely, conformantly, and in production.
One Standard for Connected Healthcare
FHIR (Fast Healthcare Interoperability Resources) turns clinical data into well-defined, web-native resources — Patient, Encounter, Observation, MedicationRequest — accessible over REST APIs. Since the 21st Century Cures Act made standardized APIs mandatory for certified EHRs, FHIR is no longer optional: it is how healthcare software talks to the rest of the ecosystem.
FHIR API Development
We build and expose conformant FHIR R4 REST APIs on top of your existing product, EMR, or legacy database — using facade architectures, HAPI FHIR, or Firely so you become interoperable without re-platforming.
EHR Connectivity
We integrate your application with the FHIR endpoints of Epic, Oracle Health (Cerner), athenahealth, and MEDITECH — reading and writing demographics, encounters, medications, results, and documents through the vendors' app programs.
SMART on FHIR Applications
Clinician- and patient-facing apps that launch inside the EHR with SMART launch context and OAuth 2.0 scopes — single sign-on, correct patient context, and app-gallery distribution to health systems.
OFF-THE-SHELF VS. CUSTOM
Off-the-Shelf FHIR Tools vs. a Built-for-You Integration
Turnkey FHIR gateways get you a conformant endpoint fast — but they rarely survive contact with a real vendor sandbox, a messy legacy feed, or an app-review cycle. Here's where a custom integration earns its cost.
Legacy HL7 v2 data
Off-the-Shelf
Often dropped, or requires a separate paid module to bridge v2 feeds into FHIR
Custom-Built with Woltrio
HL7 v2 and C-CDA mapped into FHIR resources as part of the same integration, so nothing gets silently lost
Vendor-specific quirks (Epic, Oracle Health…)
Off-the-Shelf
Generic mapping breaks on vendor-specific extensions, rate limits, and app-review requirements
Custom-Built with Woltrio
Built and tested against the real vendor sandbox, including app registration and review — not just the base spec
Clinical meaning
Off-the-Shelf
Maps fields structurally without understanding what an Encounter or MedicationStatement means clinically
Custom-Built with Woltrio
Engineers who know the clinical context, so mappings preserve meaning, not just JSON shape
Ongoing monitoring
Off-the-Shelf
Black-box uptime dashboard, little visibility when a mapping silently breaks
Custom-Built with Woltrio
Health checks and alerting built for your specific data flows, plus a team that already knows the integration when something changes
Cost model
Off-the-Shelf
Recurring per-connection or per-call licensing that scales with your usage
Custom-Built with Woltrio
A one-time engineering investment you own outright, with support scoped to what you actually need
If your product needs to move real clinical data through real vendor endpoints — not just pass a conformance test — a built-for-you integration is what holds up in production.
Full-Spectrum FHIR Engineering
Interoperability doesn't end at a conformant endpoint. We cover the full lifecycle — mapping legacy formats, moving population-scale data, securing access, and keeping exchanges real-time.
Translate ADT, ORU, and ORM feeds and C-CDA documents into FHIR resources so legacy interfaces and modern APIs coexist during your transition — no big-bang rewrite required.
THE BIGGER PICTURE
What We Integrate Around Your EHR
FHIR is the modern layer, but it rarely stands alone. A real interoperability project usually means bridging your EHR to payers, exchanges, labs, pharmacies, and patient-facing apps — each speaking its own protocol.

Why Digital Health Teams Choose Woltrio
FHIR projects fail on clinical nuance and vendor quirks, not on JSON. We bring both the standards depth and the production EHR integration experience to ship exchanges that hold up in the real world.
Clinical Data Fluency
Our engineers know what an Encounter, a ServiceRequest, and a MedicationStatement mean clinically — so mappings preserve meaning, not just structure.
Compliance Built In
HIPAA, the Cures Act API mandate, and information-blocking rules shape every architecture decision from day one — not as an afterthought before go-live.
Production Integration Experience
We've shipped integrations against certified vendor endpoints with their rate limits, app review processes, and version drift — and we build the monitoring that keeps them healthy.
Our FHIR Integration Delivery Process
- 01
Use-Case & Data Discovery
We define which clinical data needs to move, in which direction, and under whose authorization — and inventory the source systems, vendors, and standards involved.
- 02
Architecture & Profile Selection
We choose the right architecture — native FHIR server, facade, or integration engine — and pin the FHIR version, profiles, and implementation guides your exchange must conform to.
- 03
Implementation & Mapping
We build the APIs, apps, and mappings — with test fixtures for the messy real-world data that vendor sandboxes never show you.
- 04
Conformance & Security Testing
We validate against Inferno and Touchstone, exercise SMART launch and consent flows end to end, and load-test rate-limited vendor endpoints before anything touches production.
- 05
Go-Live, Monitoring & Support
We deploy with health checks, alerting, and dashboards for API traffic — and stay on for vendor version changes, app re-reviews, and new use cases.
