## Get Work Item

`BetaSelfHostedWork beta().environments().work().retrieve(WorkRetrieveParamsparams, RequestOptionsrequestOptions = RequestOptions.none())`

**get** `/v1/environments/{environment_id}/work/{work_id}`

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.

Retrieve detailed information about a specific work item.

### Returns

- `class BetaSelfHostedWork:`

  Work resource representing a unit of work in a self-hosted environment.

  Work items are queued when sessions are created or when long-dormant sessions
  receive new messages. The environment worker polls for work to execute in a
  self-hosted sandbox.

  - `String id`

    Work identifier (e.g., 'work_...')

  - `Optional<String> acknowledgedAt`

    RFC 3339 timestamp when the work item was acknowledged and assigned to a self-hosted sandbox

  - `String createdAt`

    RFC 3339 timestamp when work was created

  - `BetaSessionWorkData data`

    The actual work to be performed

    - `String id`

      Session identifier (e.g., 'session_...')

    - `JsonValue; type "session"constant`

      Type of work data

      - `SESSION("session")`

  - `String environmentId`

    Environment identifier this work belongs to (e.g., `env_...`)

  - `Optional<String> latestHeartbeatAt`

    RFC 3339 timestamp of the most recent heartbeat

  - `Metadata metadata`

    User-provided metadata key-value pairs associated with this work item

  - `Optional<String> startedAt`

    RFC 3339 timestamp when work execution started

  - `State state`

    Current state of the work item

    - `QUEUED("queued")`

    - `STARTING("starting")`

    - `ACTIVE("active")`

    - `STOPPING("stopping")`

    - `STOPPED("stopped")`

  - `Optional<String> stopRequestedAt`

    RFC 3339 timestamp when stop was requested

  - `Optional<String> stoppedAt`

    RFC 3339 timestamp when work execution stopped

  - `JsonValue; type "work"constant`

    The type of object (always 'work')

    - `WORK("work")`
