HL7 FHIR integration without breaking the EHR contract
Most healthcare integration failures happen at the boundary between what a sandbox promises and what a live EHR instance actually returns. We build against FHIR R4 resources (Patient, Encounter, Observation, MedicationRequest, DocumentReference) using SMART on FHIR launch sequences and OAuth2 scopes, and we test against the vendor's certification environment before touching a production tenant.
Where a hospital still runs HL7 v2 feeds for ADT or lab results alongside a newer FHIR API, we build the interface engine to carry both, mapping v2 segments to FHIR resources instead of forcing a hospital to migrate everything at once. Rate limits, webhook retries and version drift between a health system's sandbox and production FHIR server get handled in the integration layer, not discovered after go-live.
- SMART on FHIR app launch and OAuth2 scope negotiation
- HL7 v2 to FHIR R4 resource mapping for legacy ADT and lab feeds
- Webhook-based sync with retry and dead-letter handling for dropped messages
