Get a cycle

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

Fetch one cycle by id. The response is the same cycle object the list endpoint returns for each row, so you only need this call when you already hold an id.

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. A cycle id from a different project returns 404, not the record.

pk:requiredstring (uuid)

The cycle to retrieve.

No ?expand= on cycles

Cycles do not support ?expand=. owned_by_id and created_by_id are always plain ids — resolve them against the members endpoints when you need display names.

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.
