Pass force=true to delete permanently. A project with logged time is refused with 409 has_logged_time. A soft delete leaves the project's notes, drive items and tags in place, so a restore brings it back intact; only force=true removes them.

Path parameters

projectintegerRequired

The Project's numeric id. Accepts a soft-deleted record.

Query parameters

Unknown parameters are refused with 400, naming the parameter.

forceboolean

Delete permanently instead of soft-deleting, so the record cannot be restored. It needs no token ability beyond the one every delete needs.

Default: false

Request headers

If-Matchstring

The ETag a write is conditional on. A stale validator is 412 precondition-failed.

Response 204

Returns no content.
