List states

GET/api/v2/workspaces/{slug}/projects/{project_id}/states/

Return the states in a project as a paginated list. This is how you resolve a state name to the state_id you need when creating or moving a work item, and how you build a state picker that stays in sync with the project's workflow.

Results are scoped to a single project — states are never shared across projects, so there is no workspace-wide state list.

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 whose states you want to list.

Query Parameters

Filters combine with AND. The enum-backed filters group and group__in are validated: an unrecognized value is rejected with a 400 invalid_request instead of quietly returning an empty list, so a typo surfaces immediately rather than looking like "no results". order_by and paginate are not validated — an unrecognized order_by silently falls back to the default ordering and anything other than paginate=cursor silently uses offset pagination, so check your spelling there.

group:optionalstring

Return only states in this workflow group. One of backlog, unstarted, started, completed, cancelled, or triage.

Use the group__in variant to match several groups at once, passing them comma-separated — ?group__in=started,completed. Filtering by group is the portable way to ask "what counts as in progress here", because every project names its states differently but the groups are fixed.

is_default:optionalboolean

Return only the project's default state (true) or only the non-default states (false). Pairing ?is_default=true with ?per_page=1 is the cheapest way to find where new work items will land.

external_id:optionalstring

Return states whose external_id matches exactly. Use it to find the state you previously created for a record in another system.

external_source:optionalstring

Return states that came from a particular system, for example github or jira. Combine it with external_id — an external_id is only unique within its source.

search:optionalstring

A search term matched against the state name.

Ordering

order_by:optionalstring

Field to sort by. Prefix with - for descending.

• sequence , -sequence — the project's own workflow order
• created_at , -created_at — when each state was added
• id , -id

Order by sequence when you are rendering the workflow to a user; it is the order the project itself uses.

Pagination

per_page:optionalinteger

Page size. Defaults to 50, maximum 200. Most projects have fewer than 20 states, so one page is usually the whole workflow.

offset:optionalinteger

Number of rows to skip from the start of the result set. Maximum 10000. Read the next value from the response rather than computing offsets yourself.

paginate:optionalstring

Set to cursor to opt into the COUNT-free keyset envelope, which returns next_cursor and has_more instead of next and total_count. Omit it for the default offset envelope.

count:optionalboolean

Defaults to true. Set to false to skip the COUNT(*) behind total_count; the field is then omitted from the response.

Response shaping

fields:optionalstring

Comma-separated list of fields to return on each row. 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.

Read the group, not the name

A project can rename In Progress to Building at any time, and reporting keeps working because boards and burndowns read group. Write integrations the same way: match on group, and treat name as a label for humans.
