How Integration Works

Real-time data streaming with event-driven architecture

Event-Driven Sync
Instant data delivery via webhooks

Polar notifies Healix whenever new data is available, and we immediately POST the normalized data to your webhook endpoint.

Available Data Types:

Activity
Daily
Sleep
Historical Data Access
Query past data with HTTP requests

Request historical data or data over extended periods using HTTP endpoints with start_date and end_date parameters.

Data Formats:

JSON
FIT File
FHIR
