Get an activity

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

Activities are the append-only audit trail on a work item. Read a single activity by id.

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 belongs to. Accepts the work item UUID or its PROJ-123 identifier.

pk:requiredstring (uuid)

The activity id.

Response shaping

fields:optionalstring

Comma-separated list of fields to return. Fields you don't request are left out of the response instead of coming back as null. id is always included. Pass all to get every requestable field. An unknown field name returns 400. See Sparse fields.

Requestable here: actor_id, comment, created_at, duration, epoch, external_id, external_source, field, id, issue_comment_id, new_identifier_id, new_value, old_identifier_id, old_value, updated_at, verb, work_item_id.

expand:optionalstring

Comma-separated relations to embed: actor.

Expanded objects get their own key: ?expand=state keeps state_id and adds a state object next to it. ?fields= and ?expand= work independently. Naming a relation in ?fields= returns 400, and field filtering never removes an expanded object. See Expanding relations.
