# How do I read partial field availability on the support page?

On the [wearable-data support page](https://docs.tryterra.co/reference/health-and-fitness-api/supported-integrations), a **partial-support indicator means data may arrive from that device but not all fields will be populated**. This reflects both device hardware and what the provider's API exposes for that model.

Availability is device- and provider-specific. For example, some HRV/VO2 max metrics depend on hardware generation, and certain fields like Polar resting HR via the Body event are not currently delivered.

**Check per-field and per-device support** rather than assuming full coverage.
