How Suunto API integration works.
User connects their Suunto account
Open Wearables handles the Suunto API OAuth flow. Your users authorize access through Suunto's standard consent screen. Token management is handled automatically.
Data is normalized to a unified schema
Workout data, GPS traces, heart rate, altitude, and activity metrics from Suunto are ingested and mapped to Open Wearables' unified health data schema. Consistent structure across all connected providers.
Your application calls one unified API
The same endpoints work for every provider. No Suunto-specific parsing logic, no managing individual workout endpoints.
Suunto is just the start.
One unified health data API, every provider. Plus health scores and AI reasoning.
All providers, one schema
Garmin, Whoop, Oura, Strava, Apple Health, Polar, Samsung Health, Google Health Connect. Same endpoints, same data format.

Why Open Wearables for Suunto.
Outdoor and multisport data
Suunto specializes in outdoor sports. Trail runs, hikes, ski touring, open-water swims. GPS traces, altitude profiles, and elevation data are first-class in the Suunto API. Open Wearables exposes all of it.
Full GPS trace data
Route polylines, elevation profiles, and split data for every recorded workout. Open Wearables normalizes Suunto's GPS format into the same structure used by Garmin and Strava.
No Suunto-specific parsing in your backend
No need to learn Suunto's response format or endpoint structure. Your application queries one schema regardless of the provider.
Combine with other providers
Pair Suunto outdoor activity data with Oura sleep or Whoop recovery in one query. One schema, every device.
