Get a workflow activity

GET/api/v2/workspaces/{slug}/projects/{project_id}/workflows/{workflow_id}/activities/{pk}/

Retrieve one entry from a project workflow's audit trail by id. The entry must belong to the workflow in the path. An entry from another workflow returns 404.

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

workflow_id:requiredstring (uuid)

The workflow the entry belongs to.

pk:requiredstring (uuid)

The id of the activity entry.

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: actor_id, created_at, epoch, field, id, new_identifier, new_value, old_identifier, old_value, state_id, verb, workflow_id.

See Sparse fields.
