# Why are glucose and temperature samples missing?

Sample-level data such as glucose and temperature readings is **only included when the request sets `with_samples=true`**. With `with_samples=false`, detailed samples are stripped from the payload.

If a field is still absent with samples enabled, the provider may not expose it through their API. In that case it can be raised with the provider as an enhancement.
