# List Work Items

`GET /v1/environments/{environment_id}/work?beta=true`

Note: these endpoints are called automatically by the pre-built environment worker provided in the SDKs and CLI, for orchestrating sessions with self-hosted sandbox environments. They are included here as a reference; you do not need to invoke them directly.

List work items in an environment.
