Delete a label

DELETE/api/v2/workspaces/{slug}/projects/{project_id}/labels/{pk}/

Remove a label from a project. The label is removed from every work item that carried it. Nothing else about those work items changes.

A successful delete returns 204 with an empty body. Don't parse the response.

Path parameters

slug:requiredstring

The workspace slug. It appears in your Plane URLs. In https://app.plane.so/my-team/projects/, the slug is my-team.

project_id:requiredstring (uuid)

The project the label belongs to.

pk:requiredstring (uuid)

The label id to delete.

Response shaping

fields:optionalstring

Comma-separated list of fields to return. Fields you don't request are left out of the response instead of coming back as null, so a missing key means you didn't ask for it and null means the value is null. id is always included, whether or not you name it.

Pass all to get every requestable field. An unknown field name returns 400 with the list of valid names and the closest match, so a typo is caught instead of being silently ignored.

Requestable here: color, created_at, created_by_id, description, external_id, external_source, id, name, parent_id, sort_order, updated_at, updated_by_id.

See Sparse fields.

Scopes

projects.labels:write

Errors

Status	Code	Cause
400	invalid_request	A path parameter is malformed, for example a pk that isn't a UUID.
400	workspace_managed	The workspace has governance turned on, so project labels are read-only. The body has error and code keys instead of the problem format. See Workspace governance.
401	unauthorized	Missing or invalid credentials.
402	payment_required	The feature this endpoint belongs to isn't enabled on your plan, or is switched off.
403	forbidden	Your role or token scope can't delete labels.
404	not_found	No such label in this project, or the workspace or project is outside your tenant.
406	not_acceptable	The Accept header asks for a representation the API can't produce.
409	conflict	The write collides with an existing record or a business rule.
413	payload_too_large	The request body is over the size limit.
415	unsupported_media_type	The Content-Type isn't one this endpoint accepts.
429	rate_limited	Throttled. Honor the Retry-After header before retrying.

Labels have no delete protection. No label is pinned the way a project's default state is, and a label still applied to work items deletes normally.

Deleting is not the same as unassigning

If you only want the tag off a few work items, update those work items' label_ids instead. Deleting the label strips it from every work item in the project at once, and there is no undelete endpoint. To undo it, you have to recreate the label and reapply it everywhere.

Deleting twice

A repeated delete returns 404, not 204. Treat both as "the label is gone" when your job is idempotent.
