# Get User

`GET /api/v1/users/{user_id}`

## Path parameters

- `user_id` string, uuid, required

## Headers

- `X-Open-Wearables-API-Key` string, nullable

## Response `200`

Successful Response

- UserRead
  - `id` string, uuid, required
  - `created_at` string, date-time, required
  - `first_name` string, nullable
  - `last_name` string, nullable
  - `email` string, email, nullable
  - `external_user_id` string, nullable — 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.
  - `last_synced_at` string, date-time, nullable
  - `last_synced_provider` string, nullable
  - `has_active_connection` boolean

## Other responses

- `400` — Validation error
- `401` — Authentication required
- `404` — User not found
- `422` — Validation Error
