How to integrate with the Fitbit API: ROOK simplifies access to Fitbit wearable data for health, fitness, and insurance apps.
How it connects
Fitbit is now called Google Health. ROOK's Fitbit Web API integration delivers body metrics, physical activity and sleep data from Fitbit devices as structured JSON, by webhook and API.
Our Fitbit integration delivers notifications within minutes after a user completes an event and syncs their app.
