List labels

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

Return the labels defined in a project. Use it to build a label picker, to resolve label names to ids before writing label_ids on a work item, or to look up a label you imported by its external_id.

Results are paginated. Labels from other projects are never included — a project's labels are its own.

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 labels you want.

Query Parameters

Filters

parent_id:optionalstring (uuid)

Return only the labels nested under this label.

Pair it with parent_id__isnull=true to get the opposite view — every top-level label in the project. Use parent_id__isnull=false for every label that has a parent.

external_id:optionalstring

Return labels whose external_id matches. Combine with external_source to resolve a record from another system to its Plane label without keeping a local id map.

external_source:optionalstring

Return labels that came from this system, for example github or jira.

Search

search:optionalstring

A search term matched against the label name. Use it to power type-ahead in a picker rather than downloading every page and filtering client-side.

Ordering

order_by:optionalstring

Field to sort by. Prefix with - for descending. Defaults to sort_order.

• sort_order , -sort_order — the project's own label ordering
• created_at , -created_at — newest or oldest first
• id , -id

A value outside this list is not rejected — it silently falls back to the default sort_order. Check your spelling: a typo in order_by fails silently and shows up as a differently sorted page, not as an error.

Pagination

per_page:optionalinteger

Page size. Defaults to 50, maximum 200.

offset:optionalinteger

Number of rows to skip from the start of the result set. Maximum 10000. Read the next value from the response and send it back as offset to walk forward.

paginate:optionalstring

Set to cursor to switch from the default offset envelope to the keyset cursor envelope, which skips the COUNT(*) and returns next_cursor and has_more instead of next and total_count. Send the returned next_cursor back as cursor to fetch the following page.

Only created_at and id are cursor-eligible, because a keyset needs a strictly ordered column and sort_order is neither unique nor monotonic. Pair paginate=cursor with order_by=created_at or order_by=id — the default sort_order ordering is rejected with 400 ordering_not_cursor_eligible.

Most projects have few enough labels that the default offset envelope is all you need.

count:optionalboolean

Defaults to true. Set to false to omit total_count and skip the count query.

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, id, name, parent_id, sort_order.
