Challenge
Revised daily documents overwrite good data
Agnotic approach
Idempotent, version-aware ingestion so revisions update cleanly without corrupting history.
Sleep, recovery and research products need Oura Ring data they can trust, soon after members sync. We build the Oura API v2 connection end to end (OAuth2 consent, daily sleep, readiness, activity, heart rate and webhook subscriptions) mapped into FHIR Observations through a HIPAA-ready pipeline.
Trusted by global innovators
























The Oura API v2 gives apps consented access to Oura Ring data, including daily sleep, readiness, activity, heart rate and workouts, through OAuth2 and webhooks. It suits sleep, recovery, women's health and research products. Agnotic Technologies builds the connection, the consent flow and the pipeline that maps Oura data into your platform.
Oura's ring produces trusted sleep and recovery data (sleep stages, readiness, resting heart rate, HRV, temperature deviation and daily activity) through the Oura API v2 cloud REST interface. Users authorize your app via OAuth2; you then read daily summary documents and can subscribe to webhooks.
The nuance is the daily-document model. Oura returns derived sleep, readiness and activity scores with raw samples, so the pipeline decides what to store and reconciles revised documents. Mapping sleep stages, HRV and temperature into coded FHIR Observations and handling webhook re-delivery make it research-grade.
A pipeline from the Oura API v2 to a FHIR-native record for sleep, readiness, and recovery.

Common failure modes
Challenge
Revised daily documents overwrite good data
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
Reliable 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.
Subscriptions on new and updated documents, reconciled against pulls to keep the record current.
Sleep stages, readiness, resting heart rate, HRV, and temperature deviation at document fidelity.
Each metric mapped to FHIR R4 with LOINC codes, UCUM units, and clear provenance.
Handle late-arriving and revised daily documents so the longitudinal record stays accurate.

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 | daily scope | Stages, efficiency, and resting heart rate. |
| Readiness | Daily readiness | daily scope | Readiness score, HRV balance, temperature. |
| Activity | Daily activity | daily scope | Activity score, steps, and calories. |
| Heart rate | Heart rate | heartrate scope | Time-series heart rate. |
| Notifications | Webhook subscription | Webhook | New/updated documents; reconcile against pulls. |
Daily documents can be revised after first delivery, so idempotent reconciliation matters.

The Oura API V2 is the only available integration point for Oura data; the previous V1 API has been sunset.
