Polar Continuous Heart Rate API is one of 19 APIs that [Polar](https://apis.io/providers/polar/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification and an AsyncAPI event-driven specification. Tagged areas include Continuous Heart Rate. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, an AsyncAPI specification, and code examples.

This resource allows partners to access their users' continuous heart rate data. Continuous heart rate is recorded with supported devices when the heart rate tracking is turned on in device settings. Samples are recording in 5 minute intervals. Heart rate samples from training sessions are not available through this resource. Training sessions samples have more precise sampling interval and they can be accessed from the [training data resource](#exercises). <a href="https://support.polar.com/en/support/the_what_and_how_of_polars_continuous_heart_rate">Supported devices</a>
