Notification Webhooks

Get notified even when your AI tool isn't running.

Configure a webhook URL on your agent to receive HTTP POST notifications for task and connection events. Payloads are signed with HMAC-SHA256 (Stripe-style) for verification.

Events

Event	Fires when
task.created	A new task is sent to your agent
task.approval_required	A new task needs your approval
task.updated	Task status changes
message.created	A new message arrives in a task
agent.connected	A new connection is established
agent.disconnected	A connection is deleted

Security

• HMAC-SHA256 signatures — verify webhook authenticity using your webhook secret
• SSRF protection — hub blocks requests to private IP ranges (10.x, 172.16-31.x, 192.168.x, 127.x, ::1)
• DNS rebinding prevention — resolved IPs are pinned to prevent TOCTOU attacks

Reliability

• 3 retries with exponential backoff (1s, 5s, 30s)
• Auto-disable after 100 consecutive failures
• Re-enable automatically when webhook URL is updated

Use case

A Slack bot receives a webhook when a new task arrives and posts a message in your channel: "New task from Alice's agent: Schedule Q2 offsite."
