Get a cycle

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

Fetch one cycle by id. The response is the full cycle object, including the six progress counts that list rows leave out unless ?fields= names them. See Progress counts.

An archived cycle resolves here too, with archived_at set, even though the default list hides it.

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.

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: archived_at, backlog_issues, cancelled_issues, completed_issues, created_at, created_by_id, description, end_date, external_id, external_source, id, logo_props, name, owned_by_id, progress_snapshot, sort_order, start_date, started_issues, timezone, total_issues, unstarted_issues, updated_at, updated_by_id.

See Sparse fields.

expand:optionalstring

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

Expanded objects get their own 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 returns 400.

?fields= and ?expand= take separate sets of names. Relation names aren't valid in ?fields=, field names aren't valid in ?expand=, and field filtering never removes an expanded object: ?fields=id,name&expand=state returns id, name and state. See Expanding relations.
