Challenge
Revised daily documents overwrite good data
Agnotic approach
Idempotent, version-aware ingestion so revisions update cleanly without corrupting history.
We integrate the Oura API v2 end to end — OAuth2 consent, daily sleep, readiness, activity, and HRV endpoints, and webhook subscriptions — normalized into FHIR Observations through a HIPAA-compliant pipeline. Real integrations, not just familiarity.
Trusted by global innovators
























Oura's ring produces some of the most trusted consumer sleep and recovery data — nightly sleep stages, readiness and resting heart rate, HRV, temperature deviation, and daily activity — exposed through the Oura API v2 as a cloud REST interface. Users authorize your app via OAuth2, after which you read daily summary documents and can subscribe to webhooks for new data.
The nuance is in the daily-document model and derived scores. Oura returns already-derived daily sleep, readiness, and activity scores alongside raw samples, so your pipeline must decide what to store and how to reconcile late-arriving or revised documents. Mapping Oura's sleep stages, HRV, and temperature signals into FHIR Observations with correct coding — and handling webhook re-delivery cleanly — is what turns a wellness feed into a clinical or research-grade source.

Common failure modes
Challenge

Agnotic approach
Idempotent, version-aware ingestion so revisions update cleanly without corrupting history.
Challenge
Webhook re-delivery double-counts data
Agnotic approach
De-duplication keyed on document identity keeps the record accurate.
Challenge
Derived scores mistaken for raw signals
Agnotic approach
We map both scores and underlying samples to distinct FHIR Observations with clear provenance.
Challenge
Refresh tokens expire and break sync
Agnotic approach
Robust token rotation and re-consent flows so users don't silently drop off.
The exact Oura API v2 surface your integration rides on.
Daily sleep, readiness, activity, HRV, and temperature endpoints returning summary documents.
Authorization Code flow with scoped consent and refresh-token rotation for ongoing access.

Standards we build against
A phased approach across app registration, OAuth2, and FHIR mapping.
We map the Oura endpoints and scopes your use case needs and their FHIR targets.
Register the Oura app, configure scopes and redirect URIs, and build the Authorization Code flow.
Document pulls, webhook subscriptions, revision handling, and FHIR mapping validated against test accounts.
Phased rollout with webhook-health and reconciliation monitoring once live.
Data model
Oura's daily-document model shapes the integration.
| Data | Endpoint | Access | Notes |
|---|---|---|---|
| Sleep | Daily sleep | OAuth2 scope | Stages, efficiency, and resting heart rate. |
| Readiness | Daily readiness | OAuth2 scope | Readiness score, HRV balance, temperature. |
| Activity | Daily activity | OAuth2 scope | Activity score, steps, and calories. |
| Notifications | Webhook subscription | Webhook | New/updated documents; reconcile against pulls. |
Daily documents can be revised after first delivery, so idempotent reconciliation matters.
Related proof of compliant, integration-heavy delivery: the privacy-first data layer we built for Lera Health reflects the discipline we bring to ingesting Oura sleep and readiness data into a compliant FHIR record.

We ship Oura integrations that handle the daily-document model cleanly.
