# List the measurement IDs the current user is watching

`GET /projects/{project_id}/lab/watched`

Return the IDs of measurements the current user is watching.

A flat list of IDs for membership testing on the client. Includes watches on
measurements that may since have finished; the Lab wall intersects them with
its live channels, so finished watches simply do not surface.

## Path parameters

- `project_id` string, required

## Response `200`

Successful Response

- WatchedMeasurementIds — The set of measurement IDs the requesting user is currently watching. Returned as a flat list of IDs (not full rows) because callers only need to test membership — e.g. to mark channels as watched on the Lab wall.
  - `measurement_ids` string[] — IDs of live measurements the user is watching

## Other responses

- `422` — Validation Error
