Garmin Integration

Garmin wearables (Forerunner, Fenix, Venu, vivoactive) provide continuous heart rate, HRV, stress scores, and activity data. Integrate with Nefesh via the Garmin Connect IQ SDK or the Garmin Health API.

Integration Options

Method	Best For	Data
Connect IQ App	Real-time streaming	HR, HRV, stress, activity level
Health API	Batch/historical sync	Daily summaries, sleep, activities

Connect IQ (Real-Time)

Build a Connect IQ data field or widget that reads sensor data and sends it to your companion app on the phone. The companion app forwards the data to Nefesh.

Health API (Batch Sync)

Register for Garmin Health API access, subscribe to push notifications for user activities, and forward the data to /v1/ingest.
