Polar API Integration

Terra's Polar API integration will enable your users to sync their Polar watches & heart rate straps with your app. The Polar API integration will give you detailed insights through providing users' highly accurate heart rate, sampled as frequently as every second, and will provide you with Polar's proprietary step count whenever a user's device syncs to the cloud. You will also receive heart rate zone information for users' workouts, and summaries of users' sleep for each night.

How the Polar API integration works

Data delivery: Polar pushes to Terra on change
Expected latency: Seconds after the provider syncs
Data types: Activity, Daily and Sleep, normalized by the Terra unified API
Credentials: Terra manages the Polar API credentials, so there is nothing to register

Two ways to receive Polar data

When data is available from a Polar device, Terra sends it straight to your webhook. During your Terra account setup you'll be prompted for a callback URL, and that is where Terra POSTs each payload.

Polar notifies Terra as soon as new data is available, and we POST the normalized payload straight to your webhook. No polling needed.

Terra API preserves the raw data from the wearable, it just standardizes the units and the json format. It doesn’t augment or change the raw data in any way.

Data is organized into one of 6 data types.

People Often Ask Us...

How do I access Polar data via API?

Terra provides a web API integration with Polar. After your users authenticate through Terra's widget, their Polar watch and heart rate strap data is automatically synced to your app via webhooks or available through the REST API.

How quickly does Polar data reach my app?

Polar notifies Terra as soon as new data is available, so the normalized payload reaches your webhook within seconds of the user's device syncing. Workout data, daily activity summaries, and sleep information all arrive without you asking for them.

What data is available from Polar through Terra?

Through Terra's Polar integration, you can access activity, daily and sleep data. This includes highly accurate heart rate sampled as frequently as every second, proprietary step counts, heart rate zone information for workouts, and nightly sleep summaries.

How much does the Polar API integration cost?

Every Terra plan includes unlimited integrations, so there is no separate charge for Polar. Pricing is credit-based, with 100,000 credits included each month and usage-based rates beyond that. Every plan carries a 30-day money-back guarantee, so you can build against real Polar data risk-free.
