Delete a cycle

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

Remove a cycle from a project. The delete is a soft delete — the cycle stops appearing in reads and its name is freed for reuse.

A successful call returns 204 with an empty body. There is nothing to parse, so branch on the status code.

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 cycle belongs to.

pk:requiredstring (uuid)

The cycle to delete.

Deleting the cycle does not delete its work items

Work items that were in the cycle survive the delete — they simply lose their cycle assignment. Move them to another cycle first if the assignment matters, using Transfer work items between cycles.

Deleting a cycle that is already deleted returns 404, so the call is safe to retry: treat both 204 and 404 as "gone".

Response shaping

fields:optionalstring

Comma-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: created_at, created_by_id, description, end_date, external_id, external_source, id, logo_props, name, owned_by_id, sort_order, start_date, timezone.

See Sparse fields.

expand:optionalstring

Comma-separated relations to embed alongside the ids: owned_by (the cycle owner).

Expansion is separate-key: ?expand=state keeps state_id and adds a state object next to it, so an id is never replaced by an object. An unknown value is a 400.

?fields= and ?expand= are independent namespaces. Relation names are not valid ?fields= tokens (and vice versa), and an expanded object survives field filtering — ?fields=id,name&expand=state returns id, name and state. See Expanding relations.

Errors

Status	Code	Cause
400	invalid_request	A malformed path parameter, for example a pk that isn't a UUID.
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 cycles in this project.
404	not_found	No such cycle, wrong project, or the record is outside your tenant.
406	not_acceptable	The Accept header asks for a representation the API can't produce.
409	conflict	The cycle's current state blocks deletion.
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.
