Get a workspace workflow transition

GET/api/v2/workspaces/{slug}/workflows/{workflow_id}/state-transitions/{pk}/

Retrieve one transition of a catalog workflow, with its target, its rejection state, and its approvers.

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.

workflow_id:requiredstring (uuid)

The catalog workflow the transitions belong to.

pk:requiredstring (uuid)

The id of the transition.

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, id, member_ids, rejection_state_id, required_approvals, transition_state_id, updated_at, workflow_state_id.

See Sparse fields.
