# Where do Garmin VO2 max and sleep score appear?

Garmin metrics are **split across payload types**, so inspecting only the daily webhook makes them look empty. Listen to the body and sleep events, not just daily:

* **VO2 max**: body data payload (in the measurements section, alongside bodyfat and weight), only on days the device computes or changes it (typically after qualifying outdoor runs/rides).
* **HRV**: sleep payload.
* **Sleep score**: sleep payload.
* **Body Battery**: daily payload.
* **Respiration**: under breaths data in the sleep payload.

Some metrics visible in the Garmin app (e.g. endurance score) are not exposed by Garmin's API and cannot be delivered.

Separately, Garmin devices only support realtime streaming of heart rate, so `STEPS`, `SPEED` and other realtime types will not stream. See the [data models reference](https://docs.tryterra.co/reference/health-and-fitness-api/data-models) for field locations.
