OURA API V2 INTEGRATION

Direct access to the Oura Cloud infrastructure to pull high-fidelity sleep architecture, HRV, and temperature deviation data.

The Oura Ring Gen3 is arguably the most accurate consumer sleep staging device available. While the app provides a "Readiness Score," our methodology requires bypassing this subjective aggregation to analyze the raw rMSSD (HRV) and temperature deviation values directly.

Authentication

Access requires generating a Personal Access Token (PAT) from the Oura Cloud developer portal. This token must be passed as a Bearer token in the Authorization header of every request.

curl -H "Authorization: Bearer YOUR_TOKEN_HERE" \
     https://api.ouraring.com/v2/usercollection/sleep \
     -d start_date=2023-11-01 \
     -d end_date=2023-11-30

This endpoint yields the critical `rmssd_5min` array, providing the necessary resolution to calculate your own rolling baselines and detect acute parasympathetic suppression.
