Streaming de eventos

$client->beta->sessions->events->stream(string sessionID, ?list<BetaManagedAgentsDeltaType> eventDeltas, ?list<AnthropicBeta> betas, ?string workspaceID): ManagedAgentsStreamSessionEvents

GET/v1/sessions/{session_id}/events/stream

Parameters

sessionID: string

eventDeltas?:optional list<BetaManagedAgentsDeltaType>

When set, this connection also receives streaming deltas (event_start, event_delta) while an event is being produced, before the event itself arrives. Deltas are best-effort; when the final event is produced it carries the complete content. A model request that ends early (an error or interrupt) produces no final event — its terminal span.model_request_end closes the preview. Accepts one or more event types to preview and may be repeated: agent.message streams content_delta fragments; agent.thinking is start-only — a signal that the agent has begun extended thinking, concluded by the agent.thinking event itself. Only previews of the requested event types are sent.

betas?:optional list<AnthropicBeta>

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

workspaceID?:optional string

Returns

class ManagedAgentsStreamSessionEvents
