# Why are Garmin step samples empty but totals correct?

This is **expected Garmin behaviour**.

* **Step totals** come from Garmin's dailies webhook, sent reliably each sync.
* **Step samples** (the sub-daily time series) come from a separate epochs webhook that Garmin pushes inconsistently, depending on the device and the granularity it recorded and synced.

When no epoch data arrives for a day, the step samples array is empty even though the total is populated. The total is always present.

Encourage users to **sync via the Garmin Connect app** for the best chance of sample data.
