# Update Project

> Update an existing project's fields

# PUT /projects/{project_id}

Updates an existing project. Only the fields included in the request body are modified; omitted fields remain unchanged.

## Notes

* Requires workspace write access.
* The `project_id` path parameter is the workspace-scoped project index.
* All fields are optional. Provide only the fields you want to change.
* Updatable fields: `name`, `status`, `locationId` or `globalLocationId`, `timezoneOverride`, `boundaryGeometry`, `projectDetails`.
* If `locationId` or `globalLocationId` is provided, the referenced location must exist in the workspace.
* The `status` field must be a valid lifecycle stage: `prospecting`, `development`, `financing`, `construction`, `operating`, or `archived`.
* Returns the full updated project resource on success.
* Returns `404` if the project or the referenced location does not exist.
