How the Oura API integration works
- Data delivery
- Oura pushes to Terra on change
- Expected latency
- Seconds after the provider syncs
- Data types
- Activity, Body, Daily and Sleep, normalized by the Terra unified API
- Credentials
- Terra manages the Oura API credentials, so there is nothing to register
Two ways to receive Oura data
When data is available from an Oura device, Terra sends it straight to your webhook. During your Terra account setup you'll be prompted for a callback URL, and that is where Terra POSTs each payload.
Oura notifies Terra as soon as new data is available, and we POST the normalized payload straight to your webhook. No polling needed.
Oura's Activity
Payload Preview
Terra API preserves the raw data from the wearable, it just standardizes the units and the json format. It doesn’t augment or change the raw data in any way.
Data is organized into one of 6 data types.

Sleep Metric Variation Across Wearables
We analyzed sleep data from 77,000+ nights across six major wearables, then zoomed in on same-person, same-night overlaps to isolate true device differences. The headline: most trackers converge on sleep duration — averages cluster around ~7 hours and median night-to-night differences are typically ~15–22 minutes. But once you break sleep into stages, agreement falls apart: REM, deep, and light can diverge by hours in direct comparisons, highlighting how much staging depends on each company’s sensors and algorithms. The takeaway is practical: trust trends in total sleep time, treat stage minutes as directional, and avoid over-optimizing for a “perfect” score when the underlying measurements don’t match.

How HRV Actually Works
We unpack what HRV really is and how it actually works to demystify the data from Apple Watch, Fitbit, and Garmin. Some devices deliver stronger signals for daily recovery (RMSSD), tightly linked to resting heart rate, while Apple produced significantly higher variability by measuring broader autonomic balance (SDNN). The results expose a fundamental metric divide: these devices are speaking different mathematical languages, meaning your choice of wearable determines whether you are tracking training readiness or overall stress.

Benchmarking Wearable Sleep Data Reliability
We analyzed sleep data from over 5,000 real-world nights across Apple Watch, Fitbit, and Garmin users. Garmin delivered the longest, most consistent sleep duration with the lowest variability and almost no outliers, while Apple consistently under-reported deep sleep and showed the highest error rates. The results reveal clear winners and losers in wearable sleep-tracking accuracy — and why device choice matters for long-term trends.
