Delete a project label
Remove a label from the workspace's project label catalog. A successful delete returns 204 with an empty body. Only workspace owners and admins can delete project labels.
You can still delete a label that projects carry. The delete removes the label's links to those projects and leaves the projects otherwise unchanged.
Path Parameters
slug:requiredstringThe workspace slug. It appears in your Plane URLs. In https://app.plane.so/my-team/projects/, the slug is my-team.
pk:requiredstring (uuid)The id of the project label to delete.
Response shaping
fields:optionalstringComma-separated list of fields to return. Unrequested keys are omitted from the response, not returned as null, so absent means "not requested" and null means "actually null". id always comes back whether or not you name it.
Pass all for every requestable field. An unknown name is a 400 that lists the valid set and suggests the closest match, so a typo can't silently cost you the saving.
Requestable here: color, created_at, created_by_id, description, id, name, sort_order, updated_at, updated_by_id.
See Sparse fields.

406 | not_acceptable | The Accept header asks for a representation the API can't produce. |
409 | governance_migration_in_progress | A governance migration is running, so the workspace is read-only. Retry after it finishes. |

Deletes are soft
The label stops appearing in the API and in Plane, but the row is kept. There is no restore operation, so treat the 204 as final.
