How to integrate with the Polar API: ROOK simplifies access to Polar wearable data for health, fitness, and insurance apps.
How it connects
ROOK's Polar Web API integration delivers body metrics, physical activity and sleep data from Polar devices as structured JSON, by webhook and API.
Harness the power of Polar data to personalize user experiences, driving higher engagement and retention.
Our Polar integration delivers notifications within minutes after a user completes an event and syncs their app.

FAQ
What teams ask before they connect Polar through ROOK.
ROOK extracts 84 Polar fields covering physical activity, sleep and body and vital signs data, grouped into summaries and events. The data each user shares depends on the permissions they grant when they connect Polar.
Our Polar integration delivers notifications within minutes after a user completes an event and syncs their app.
No. ROOK handles the Polar connection, so you only enable Polar as a data source in the ROOK portal.
Through the Polar cloud API. Users authorize their Polar account once and ROOK keeps pulling new data, with no mobile development on your side.
