Get a work item

GET/api/v2/workspaces/{slug}/projects/{project_id}/work-items/{pk}/

Retrieve one work item by its UUID. This is the endpoint to use after a list call, or any time you already hold the work item's id.

Unlike the list endpoint, this response populates custom_fields — the work item type's custom property values, keyed by property name. If you only have a PROJ-142-style key and not the project UUID, use Get a work item by identifier instead.

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 work item belongs to.

pk:requiredstring (uuid)

The work item's UUID. This lookup is UUID-only — a PROJ-142 identifier here returns 404.

Query Parameters

expand:optionalstring

Comma-separated relations to embed alongside the ids: assignees (the assigned users), cycle (the cycle it belongs to), labels (the applied labels), modules (the modules it belongs to), parent (its parent work item), state (the work item's state object), type (its work item type).

Expansion is separate-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 is a 400.

?fields= and ?expand= are independent namespaces. Relation names are not valid ?fields= tokens (and vice versa), and an expanded object survives field filtering — ?fields=id,name&expand=state returns id, name and state. See Expanding relations.

Archived work items are not returned

An archived work item sits outside the default query set, so a read of one returns 404 — the same response as a work item that never existed. Unarchive it first if you need to read it again. See Archive a work item.

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: archived_at, assignee_ids, created_at, created_by_id, custom_fields, cycle_id, id, identifier, is_draft, label_ids, module_ids, name, parent_id, priority, project_id, sequence_id, start_date, state_id, target_date, type_id.

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 work items in this project.
404	not_found	No such work item, it belongs to another project or tenant, or it's archived.
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.

What you get here that a list doesn't give you

• custom_fields — the work item type's custom property values. The list endpoint returns null for this field on every row to avoid resolving properties per row; only single-item reads populate it.
• Cheaper expansion — ?expand= works on both, but expanding one work item is a fixed cost while expanding a full page multiplies it.

Everything else — the field set, the sparse *_id shape — is identical to a row from List work items.
