# Store items in last task run's dataset

`POST /v2/actor-tasks/{actorTaskId}/runs/last/dataset/items`

Appends an item or an array of items to the end of the last Actor task run's default dataset.

This endpoint is a shortcut that resolves the last task run's `defaultDatasetId` and proxies to the
[Store items](/api/v2/dataset-items-post) endpoint.
