Fitbit API
APIAPI for accessing Fitbit fitness and health data
Overview
The Fitbit API provides RESTful endpoints to retrieve and manage user fitness/health data, including activity stats (steps, calories), sleep cycles, heart rate metrics, nutrition logs, weight trends, and device info. Responses are in JSON format. Use cases include building personalized wellness apps, syncing data with medical platforms, creating custom fitness dashboards, or enabling coaches to track client progress. It uses OAuth 2.0 for secure authentication, supporting both read operations (data retrieval) and write operations (logging activities, setting goals).
Example Integration (JavaScript)
