Original: Why Webhooks Time Out for Long-Running Autonomous Agents (and the Fix)
Short summary
Webhooks fail for long-running autonomous agents because they assume short-lived, stateless HTTP handlers. Timeouts, retries, NAT churn, and per-sender endpoints all break down when agents are busy for minutes. The proposed fix is Pilot Protocol, which gives agents permanent outbound tunnels with NAT traversal, eliminating the need for inbound endpoints or stable public IPs.
- •Webhooks timeout because they assume short-lived stateless handlers, not agent reasoning loops
- •Retries, NAT churn, and IP changes silently break webhook delivery to agents
- •Pilot Protocol offers persistent outbound tunnels with NAT traversal as an alternative
