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

FAQ
What teams ask before they connect Withings through ROOK.
ROOK extracts 83 Withings 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 Withings.
Our Withings integration delivers notifications within minutes after a user completes an event and syncs their app.
No. ROOK handles the Withings connection, so you only enable Withings as a data source in the ROOK portal.
Through the Withings cloud API. Users authorize their Withings account once and ROOK keeps pulling new data, with no mobile development on your side.
