Claude Managed Agents: Webhooks for Task Completion Notifications

What Are Webhooks in Claude Managed Agents?

Claude Managed Agents now supports webhooks for task completion notifications, enabling developers to receive real-time callbacks when long-running agent tasks finish — without polling or maintaining persistent connections. This makes it straightforward to build asynchronous workflows where an agent runs independently and downstream systems are notified automatically upon completion.

How It Works

When launching an agent task, developers can register a webhook endpoint to receive a notification payload when the task completes. The agent runs its full workflow — which may span minutes, hours, or longer depending on task complexity — and posts the completion notification to the registered URL once finished.

This model decouples task execution from result consumption. Systems that trigger agent tasks no longer need to hold open connections or implement polling loops; they simply register a webhook and wait for the notification to arrive. The webhook payload includes task status and output metadata, enabling downstream systems to route results appropriately.

What You Can Build With It

Webhooks unlock a wide range of integration patterns that are impractical with synchronous agent calls:

• Slack notifications: Alert team channels or specific users when an agent completes a report, draft, or analysis task
• Custom dashboards: Push task completion events to internal monitoring or tracking systems for visibility into agent workload and throughput
• Task routing systems: Trigger follow-on workflows automatically when an agent finishes — for example, sending a completed draft to a review queue or routing an analysis result to a downstream processing step
• Human-in-the-loop review: Notify reviewers when agent output is ready for approval before being acted on

Why It Matters

Long-running agent tasks are a core use case for Claude Managed Agents, but without an event-driven notification mechanism, integrating them into larger systems requires awkward polling patterns that waste resources and add latency. Webhooks make agent tasks first-class asynchronous operations that compose cleanly with the rest of a developer's infrastructure.

Status and Availability

Webhooks are available in public beta alongside Outcomes, Multiagent Orchestration, and Memory. Developers can get started through Claude Console at platform.claude.com.
