Challenge
OAuth2 tokens expire and break sync
Agnotic approach
We implement robust refresh-token handling with proactive renewal and alerting so connections never silently drop.
Elation Health is a primary-care EHR with one of the most developer-friendly APIs in the space. We build real integrations on it — REST, OAuth2, event webhooks, and FHIR R4 — for primary-care groups and digital-health startups.
Trusted by global innovators
























Elation Health is a clinical-first EHR built around primary care, with a Collaborative Health Record and a genuinely developer-friendly REST API. It exposes resources for patients, appointments, clinical notes, problems, medications, orders, and more, with OAuth2 authorization, event webhook subscriptions, a sandbox, and ONC-certified FHIR R4 endpoints for patient access.
That clean API is why Elation is a favorite among digital-health builders — but production still requires registering an API application, handling per-practice OAuth2 tokens with refresh, subscribing to and reliably processing event webhooks, and respecting rate limits. We build against the rich REST surface and the certified FHIR endpoints and reconcile the two into one model.
See how we structure Elation integrations with OAuth2, event webhooks, and reliable sync across clinical resources.

Common failure modes
Challenge
OAuth2 tokens expire and break sync
Agnotic approach
We implement robust refresh-token handling with proactive renewal and alerting so connections never silently drop.
Challenge
Rate limits throttle busy practices
Agnotic approach
We build request budgeting, backoff, and batching so high-volume primary care stays in sync without hitting caps.
Challenge
Webhook deliveries can be missed
Agnotic approach
We pair webhooks with periodic reconciliation polls so no event is permanently lost.
Challenge
REST vs FHIR data models diverge
Agnotic approach
We map both surfaces to one canonical model so your app sees consistent data regardless of source endpoint.
We build against Elation's exact surface — the REST resources, event webhooks, and certified FHIR R4.
The documented REST resources for patients, appointments, clinical notes, problems, medications, and orders — the rich proprietary surface most builds use.
Per-practice OAuth2 flows with access and refresh tokens and scoped access so each connected practice stays isolated.
Webhook subscriptions for patient, appointment, and clinical events so your app reacts in near real time instead of polling.
Elation's ONC (g)(10)-certified FHIR R4 resources for standardized, patient-access clinical reads where interoperability matters.
Problems, medications, and order data wired to the correct patient and encounter with terminology alignment.
A resilient sync layer with backoff, retry, and rate-limit awareness so busy primary-care practices stay reliably in sync.
Where it runs
Startup apps that read and write Elation clinical data via OAuth2.
Sharing structured clinical data across care-team platforms.
Virtual visits with documentation synced back to the record.
Wearable and device readings attached to the patient record.
Clinical and operational analytics built on Elation events.
Reminders and intake driven by live appointment events.
Elation's REST API is a joy to build on — production reliability is what turns a prototype into a live primary-care integration.

Standards we build against
App registration, OAuth2, and webhook wiring run in parallel with clinical mapping so your Elation integration lands on schedule.
We map the REST resources and events you need and confirm whether the proprietary API, FHIR, or both fit your workflows.
We register the API application, wire OAuth2 with refresh, and validate scopes and rate limits in the sandbox.
We build the REST and webhook integrations with retry and reconciliation, validated against sandbox and pilot-practice data.
Phased rollout with webhook-delivery monitoring, token-refresh health, and failed-sync alerting.
Surface at a glance
How we think about each Elation surface — method, use, and notes.
| Surface | Method | Typical use | Notes |
|---|---|---|---|
| REST API | REST + OAuth2 | Patients, notes, orders | Rich, well-documented proprietary surface. |
| Webhooks | Event subscriptions | Real-time updates | Requires reliable receiver + retry handling. |
| FHIR R4 | REST + OAuth2 | Certified clinical reads | ONC (g)(10) scope; narrower than REST API. |
| Sandbox | Test environment | Pre-prod validation | Validate scopes and flows before go-live. |
Elation's clean docs make prototyping fast; production reliability is where the real work lies.
Related proof of the API-first, compliant delivery an Elation build needs: for Lera Health we shipped a privacy-first data layer and event-driven clinical workflows end to end — the same OAuth2, webhook, and reconciliation discipline we bring to developer-friendly EHRs.

We turn Elation's clean API into a production integration with the reliability primary-care practices need.
Lean, milestone-driven cycles built for founder timelines — a working Elation integration in weeks, not quarters.
HIPAA-ready token handling, PHI isolation, and BAA-covered infrastructure designed in from sprint one.
A team that owns the integration end to end — engineering, QA, and reliability — with one point of accountability.
We've built compliant clinical products, so notes, problems, and orders are wired correctly the first time.
