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.

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.

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

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.
