Record Heartbeat

client.Beta.Environments.Work.Heartbeat(ctx, workID, params) (*BetaSelfHostedWorkHeartbeatResponse, error)
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
workID string
params BetaEnvironmentWorkHeartbeatParams
EnvironmentID param.Field[string]

Path param

DesiredTTLSeconds param.Field[int64] Optional

Query param: Desired TTL in seconds

ExpectedLastHeartbeat param.Field[string] Optional

Query param: 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.

Betas param.Field[[]AnthropicBeta] Optional

Header param: Optional header to specify the beta version(s) you want to use.
