Create a worklog

POST/api/v2/workspaces/{slug}/projects/{project_id}/work-items/{work_item_id}/worklogs/

Worklogs record time spent on a work item. Create a worklog.

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

The project the resource belongs to. Accepts the project UUID or its bare identifier, for example ENG.

work_item_id:requiredstring

The work item the resource hangs off. Accepts the work item UUID or its PROJ-123 identifier.

Body Parameters

duration:requiredinteger

Time logged, in minutes.

description:optionalstring

Free-form description.

Response shaping

fields:optionalstring

Comma-separated list of fields to return. Unrequested keys are omitted, not returned as null. id always comes back. Pass all for every requestable field. An unknown name is a 400. See Sparse fields.

Requestable here: created_at, created_by_id, description, duration, id, logged_by_id, updated_at, work_item_id.

expand:optionalstring

Comma-separated relations to embed: logged_by.

Expansion is separate-key — ?expand=state keeps state_id and adds a state object next to it. ?fields= and ?expand= are independent: naming a relation in ?fields= is a 400, and expanded objects survive field filtering. See Expanding relations.
