FHIR Integration Services
Connect your digital health product or enterprise platform to Epic, Cerner, Athena, and any FHIR R4-compliant EHR. Patient data aggregation, real-time clinical events, and SMART app launch.
The Challenge
EHR FHIR APIs Are Inconsistent — Integration Takes Specialist Knowledge
Every major EHR vendor implements FHIR R4 differently. Epic supports certain search parameters that Cerner does not. Athena has undocumented rate limits that only appear under load. Some vendors require custom extensions to access clinical data that should be in standard FHIR resources. SMART on FHIR app launch flows have subtle differences between EHR systems that require separate testing and handling. If you are building a digital health product that connects to multiple EHRs, you need an integration engineer who has already encountered and solved these problems — not one who will spend months discovering them at your expense.
Deliverables
FHIR Integration Capabilities

Process
Integration Delivery Process
A clear, predictable engagement model with no surprises.
EHR Vendor Assessment
Assess each target EHR's FHIR implementation — supported resource types, search parameters, authentication flow, rate limits, and known non-standard behaviours. Produce an integration specification before development begins.
Sandbox Integration Build
Build the integration against EHR sandbox environments. Implement SMART auth flows, data mapping, error handling, and retry logic. Document every vendor-specific behaviour encountered.
Conformance & Security Testing
Validate FHIR conformance, test SMART launch flows in all supported EHR versions, perform security testing on auth token handling, and load test under production-representative data volumes.
App Store Submission Support
Support Epic App Orchard, Cerner App Marketplace, or Athena Marketplace submission processes — including technical review preparation and responding to reviewer feedback.
Production Deployment & Monitoring
Go-live with full integration monitoring — latency, error rates, token refresh failures, and data quality checks. Post-launch support and SLA-backed incident response.
