Get a state
Retrieve one state by id. Reach for this when you already hold a state_id — from a work item, a webhook payload, or a stored mapping — and need its current name, color, or group.
Checking group before you act is the reliable way to tell whether a work item is finished: a state named Done in one project and Shipped in another both report group: "completed".
Path Parameters
slug:requiredstringThe 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 state belongs to. A state id from a different project returns 404, even inside the same workspace.
pk:requiredstring (uuid)The id of the state to retrieve.
Response shaping
fields:optionalstringComma-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: color, created_at, created_by_id, description, external_id, external_source, group, id, is_default, is_triage, name, sequence.
See Sparse fields.

Errors
| Status | Code | Cause |
|---|---|---|
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 read this project's states. |
404 | not_found | No such state, project, or workspace — or it's outside your tenant. |
406 | not_acceptable | The Accept header asks for a representation the API can't produce. |
429 | rate_limited | Throttled. Honor the Retry-After header before retrying. |
The response is flat
The state object has no nested records. created_by_id is returned as an id, so fetch the user separately if you need their name.
Existence is never leaked
A state outside your tenant returns 404, not 403. If you are resolving a cached id and get a 404, re-read the project's workflow with List states instead of retrying.
