# List planned measurements for a project

`GET /projects/{project_id}/planned_measurements`

## Request

- Base URL: `https://api.ionworks.com`
- URL: `https://api.ionworks.com/projects/{project_id}/planned_measurements`
- Auth: none declared

List a project's planned measurements.

``name`` supports Supabase filter operators (e.g. ``ilike.%formation%``
for a partial match, ``eq.Formation`` for an exact match).

``channel_id`` and ``protocol_id`` are exact match.

``started_measurement_id`` finds the request a real measurement came from,
which is what a measurement page needs to link back to its request.

``q`` is the search box's free-text query, which also matches the related
names the table shows; it composes with the column filters above.
