Challenge
Customer security review drags launch
Agnotic approach
We start Vendor Services sign-up and security-questionnaire prep before engineering is complete, and plan review time into the schedule.
Epic
Epic integration services
Your product needs Epic data, but each health system controls its own Epic access. We connect you through Vendor Services and Showroom, SMART on FHIR launch with scoped OAuth2, FHIR R4 resources and HL7 v2 feeds, so the integration reaches production at real sites.

What are Epic integration services?
Epic integration services connect your product to Epic through the interfaces Epic publishes for developers: FHIR R4 APIs, SMART on FHIR app launch and HL7 v2 interfaces. Agnotic Technologies builds these integrations for hospitals and digital health teams, covering sandbox testing, Vendor Services and Showroom steps, and go-live at each customer site.
Epic exposes clinical data through several channels. FHIR R4 serves resource access, SMART on FHIR with scoped OAuth2 serves apps launched inside the chart, and HL7 v2 carries ADT, ORU and ORM event feeds. Each path has its own registration, security review and go-live gate.
The friction is rarely the code: it is access. Vendor Services sign-up (which replaced Epic App Orchard), sandbox provisioning, scope approval and site-by-site enablement follow Epic's timelines and your customer's IT governance. We scope those dependencies first so the integration doesn't stall in a sandbox.
How does an Epic integration fit together?
A blueprint for connecting your platform to Epic across FHIR R4, SMART on FHIR launch, and HL7 v2 interfaces, with the auth, mapping, and monitoring layers production needs.
Common failure modes
Where do Epic integrations fail?
Challenge
OAuth2 scopes are over- or under-requested
Agnotic approach
We map each Epic FHIR call to a least-privilege scope up front, so approval is clean and the app passes security review.
Challenge
FHIR coverage varies by Epic version and site
Agnotic approach
Per-site capability assessment identifies what FHIR R4 supports and where we fall back to HL7 v2.
Challenge
Sandbox access lands late
Agnotic approach
We run mapping and interface build in parallel against synthetic data so work isn't blocked waiting on credentials.
Which Epic APIs and interfaces do we build on?
We name the exact surface up front, because that's what determines what's buildable, and by when.
Vendor Services & Showroom
Vendor Services sign-up for Epic support, documentation and an expanded test sandbox, and an Epic Showroom listing where you want Epic customers to find your product.
SMART on FHIR launch + OAuth2 scopes
EHR and standalone SMART on FHIR launch with scoped OAuth2: patient/*, user/*, and system/* scopes, launch context, and refresh-token handling for apps that run inside the Epic chart.
Epic FHIR API (R4)
Read and write against Epic's FHIR R4 API: Patient, Encounter, Observation, MedicationRequest, DocumentReference, and Bulk FHIR $export for population-level pulls.
HL7 v2 interfaces
ADT (admit/discharge/transfer), ORU (results), and ORM (orders) message feeds via Bridges or an interface engine where FHIR coverage doesn't reach.
Terminology & coding alignment
SNOMED CT, LOINC, ICD-10, and RxNorm mapping so data that leaves Epic lands correctly coded in your system, and vice versa.
Observability & reconciliation
Interface health dashboards, failed-message alerting, and reconciliation workflows so a dropped ADT or throttled FHIR call is caught before it becomes a clinical gap.
Where it runs
What do teams build with Epic EHR integration?
Embedded clinical apps
SMART on FHIR apps that launch in-context inside the Epic chart for point-of-care workflows.
Patient-facing apps
Authenticated patient access to their Epic record via SMART on FHIR patient scopes.
Analytics & registries
Bulk FHIR $export feeding population health, quality, and research platforms.
Results & orders flow
ORU results and ORM orders routed between Epic and lab, imaging, or specialty systems.
RPM & device data
Remote monitoring and wearable vitals written back to the Epic record as Observations.
Care coordination
ADT-driven event triggers powering referral, care-management, and transition-of-care tooling.
Epic integrations that reach a real site
Most Epic builds stall on access and review, not code. We plan those gates in from the start.

Our Process
How do we build an Epic integration?
Access, mapping, and customer approvals run as parallel tracks so the integration reaches a real Epic site on a plan you can track.
1.
Discovery & Scope
We map target Epic sites, the FHIR R4 resources and HL7 v2 messages you need, and the SMART on FHIR scopes the app will request, then confirm the Vendor Services and Showroom path.
Access-first
2.
App Registration & Sandbox
Create the app and client IDs, provision sandbox access, and validate OAuth2 launch and scope approval against Epic's test data.
Sandbox-gated
3.
Build & Test
Build the FHIR R4 and HL7 v2 interfaces plus SMART on FHIR launch, then validate against synthetic and partner-assisted data with terminology mapping in place.
Audit-ready
4.
Go-Live & Monitoring
Phased site enablement with interface health dashboards, scope and rate-limit awareness, and alert routing for failed messages.
Monitored go-live
Surface & pace
Which Epic integration surface fits your use case?
Not every Epic need uses the same channel. Here's how we choose, and what sets the pace of each.
| Surface | Method | What sets the pace | Notes |
|---|---|---|---|
| FHIR R4 API | RESTful resource read/write | Resources and scopes enabled at each site | Modern default; coverage depends on Epic version and enabled resources. |
| SMART on FHIR | OAuth2 launch + scopes | Scope approval and the customer's security review | Embedded apps that open inside the Epic chart. |
| HL7 v2 interfaces | ADT / ORU / ORM feeds | Interface build and testing with each site's Epic team | Per-site interface build; still common for legacy event flows. |
| Bulk FHIR | $export bulk data | System-level access approved by the customer | Best for population-level analytics; needs system-level scopes. |
Real-world Epic schedules are driven more by access and review than by engineering, so we plan both with your customer's Epic team from the start.

Why Partner With Us
15-Minute Scoping CallWhy bring your Epic work to Agnotic?
We treat the integration as a first-class workstream: access, compliance, and go-live planned from the first sprint.
Compliance-first by default
HIPAA-ready architecture, BAA-covered data flows, and least-privilege OAuth2 scopes designed in from sprint one, not retrofitted before an Epic security review.
Access-aware planning
We start Vendor Services sign-up and sandbox access immediately and surface Epic and customer-IT blockers to leadership early.
Real integration engineers
Engineers who have shipped FHIR R4, SMART on FHIR, and HL7 v2 to production: your team won't be educating ours on the surface.
Clinical-domain depth
We understand the workflows behind ADT, orders, and results, so mappings reflect how clinicians actually work, not just the schema.
Our relevant experience
Real Epic integrations, not just familiarity
Frequently Asked Questions
It depends on the surface (FHIR R4, SMART on FHIR or HL7 v2), how many Epic sites you need, whether you write data back, and how quickly each health system's Epic team can approve access, configure your app and join testing. We plan those gates in from the start rather than discovering them at the end.
Cost depends on the surfaces in scope, the number of resources and messages, whether you need write-back, and how many sites you roll out to. SMART on FHIR embedded apps, HL7 v2 interfaces and multi-site rollouts add effort. We scope against your exact Epic surface and share an estimate after a discovery call.
Not always. Showroom is where Epic customers discover products for use with Epic, so a listing matters if you sell to many Epic organizations. Vendor Services adds Epic support, more documentation and an expanded test sandbox. Either way, each health system decides whether to switch your app on, so we plan that approval with your customer.
The health system's Epic team approves your app or interface, configures it in their own Epic environment, grants the access and scopes it needs, and joins testing before go-live. We give their analysts a clear build list early, so their part is scheduled rather than discovered late.
Yes. We route remote-monitoring vitals and wearable data into Epic as FHIR Observations (subject to scopes and site policy), and connect telehealth and scheduling workflows via FHIR R4 and HL7 v2. Device and RPM data flows are a core part of our integration work.
Yes. FHIR R4 is our default where Epic exposes the resources you need, and we add SMART on FHIR launch for embedded apps. HL7 v2 (ADT, ORU, ORM) remains necessary for many legacy event feeds: we build both, often in the same integration.
