## Record Heartbeat

`BetaSelfHostedWorkHeartbeatResponse beta().environments().work().heartbeat(WorkHeartbeatParamsparams, RequestOptionsrequestOptions = RequestOptions.none())`

**post** `/v1/environments/{environment_id}/work/{work_id}/heartbeat`

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.

Record a heartbeat for a work item to maintain the lease.

### Parameters

- `WorkHeartbeatParams params`

  - `String environmentId`

  - `Optional<String> workId`

  - `Optional<Long> desiredTtlSeconds`

    Desired TTL in seconds

  - `Optional<String> expectedLastHeartbeat`

    Expected last_heartbeat for conditional update (optimistic concurrency). Use literal 'NO_HEARTBEAT' to claim an unclaimed lease (first heartbeat). For subsequent heartbeats, echo the server's previous last_heartbeat value exactly. Returns 412 Precondition Failed if the actual value doesn't match.
