# Does the activity webhook include GPS and lap data?

Activity payloads include:

* **GPS samples** at `data[].position_data.position_samples`
* **Lap splits** at `data[].lap_data.laps`

These arrive when samples are enabled on your account. Indoor activities have an empty `position_samples` array (no GPS) but still include laps.

If a payload looks like it is missing this data, **share it** so it can be compared against stored data.
