Get an activity
Activities are the append-only audit trail on a work item. Read a single activity by id.
Path Parameters
slug:requiredstringThe workspace slug. It appears in your Plane URLs — in https://app.plane.so/my-team/projects/, the slug is my-team.
project_id:requiredstringThe project the resource belongs to. Accepts the project UUID or its bare identifier, for example ENG.
work_item_id:requiredstringThe work item the resource hangs off. Accepts the work item UUID or its PROJ-123 identifier.
pk:requiredstring (uuid)The activity id.
Response shaping
fields:optionalstringComma-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: 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, verb, work_item_id.
expand:optionalstringComma-separated relations to embed: actor.
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.
