You would receive a Historical Pull Completion eventimmediately after the connection creation.
However, if you query Vital API immediately, you would observe no historical data.
The Historical Pull Completion event for Garmin connections does not indicate availability of historical data through the Vital API.

The Incremental Data stage
All historical and new data are delivered incrementally as Data Events (daily.data.*.*).
This behaviour is exclusive to Garmin, as a downstream effect of Garmin’s unique historical data access mechanism for third-party integrations.
Normally, when a user with an existing connection re-authenticates with the provider through Vital Link, Vital re-runs
the Historical Data Backfill stage automatically.However, this does not apply to Garmin connections — you must first deregister said users’ existing Garmin connection for the re-run to take effect.
