# Can I get raw original Garmin FIT files?

The FIT files Terra delivers are **generated from its internal unified data model**, the same as the JSON standard payloads, not the raw original device FIT files. Raw provider FIT delivery isn't supported.

For Garmin specifically, the original FIT file and the beat-to-beat R-R intervals inside it aren't reachable, because Garmin data comes from their JSON feed, which excludes the original activity file.

For efficient discovery:

{% stepper %}
{% step %}
Pull activities with `with_samples=false` to get lightweight JSON summaries (carrying activity type).
{% endstep %}

{% step %}
Re-pull only the ones you want with `with_samples=true`.
{% endstep %}

{% step %}
Use `to_webhook=false` for a synchronous response on ranges of 28 days or under.
{% endstep %}
{% endstepper %}

Raw original telemetry beyond the normalised FIT output is a feature request we may consider, but don't support today.
