Deprecated: no data-fetching endpoint (timeseries, workouts, sleep, summaries, health-scores, etc.) accepts external_user_id - they all require the Open Wearables UUID. This field was added early in the project but never wired into those endpoints, so it only works as a filter on GET /users. Store the UUID returned by POST /users in your own system instead.
