Garmin API

Garmin APIs provide high-resolution health and fitness data from millions of wearables to third-party platforms via secure, RESTful integrations.

The Garmin Connect Developer Program offers four primary integration paths: Health API, Activity API, Women's Health API, and Training API. These tools allow developers to sync over 30 specific metrics (such as VO2 max, Sleep Score, and Pulse Ox) from devices like the fēnix and Forerunner series. The architecture utilizes OAuth 2.0 for authentication and relies on real-time webhooks to push data immediately upon device sync. This setup supports a global user base of over 66 million active accounts, providing precise biometric insights for corporate wellness, insurance, and clinical research applications.
