Debug Webhook Failures
Instantly
Eliminate event debugging headaches with our Structural Reconstruction Engine. Receive, reconstruct, and diagnose every failed event in seconds.
Everything You Need to Debug Event-Driven Systems
Stop wasting hours debugging mysterious async failures. Hookmetry does the heavy lifting.
Real-Time Event Monitoring
Capture and inspect every webhook, AI callback, or automation event your application receives. View headers, payloads, and signatures instantly.
Automatic Signature Validation
Validate Stripe, GitHub, and custom HMAC signatures automatically. Identify authentication failures before they reach your logic.
Reconstruction Engine
Proprietary heuristic engine that piece-by-piece reconstructs failed events to identify structural mismatches and signature gaps.
Adaptive Intelligence
Goes beyond static error codes. Automatically detects advanced failure patterns across Stripe, n8n, GitHub, and custom agents.
Event Replay
Test your endpoints by replaying captured events. Perfect for development and debugging without waiting for external triggers.
CLI Intelligence
Run `hookmetry diagnose` from your terminal to get probable causes, framework-specific fixes, and reconstruction summaries locally.
Built for Modern Architectures
From legacy webhooks to next-gen AI agent callbacks.
Webhook Integrations
Debug Stripe payment confirmations, GitHub repository events, and Shopify updates. Automatically validate HMAC signatures and detect middleware mutations.
AI Agent Callbacks
Monitor async responses from LangChain, OpenAI structured outputs, or custom MCP tool calls. Instantly see why your agent failed to parse a response.
Workflow Automations
Catch failures in n8n, Zapier, or Make workflows before they silently drop critical data. Reconstruct the exact JSON payload that caused the crash.
How It Works
Get failure intelligence in minutes, not hours.
Create Endpoint
Get a secure, isolated ingress URL for your integration.
Configure Source
Add the URL to Stripe, GitHub, n8n, or your AI framework.
Ingest Events
Events are captured, stored, and signatures validated.
Diagnose
Our engine reconstructs failures step-by-step automatically.
