Real-time webhook debugging for developers
In-Depth Tutorials
Master complex webhook integrations with production-ready patterns, security hardening, and failure recovery strategies.
Implementing HMAC-SHA256 Signature Verification
Secure your endpoints against spoofed requests. Learn how to validate the `X-HookCheck-Signature` header using base64-encoded secret keys, handle timestamp drift beyond the 300-second tolerance window, and integrate verification middleware with Express.js, FastAPI, and Gin.
Read Signing GuideConfiguring Exponential Backoff & Dead Letter Queues
Design resilient delivery pipelines that survive transient network failures. Configure custom retry intervals (15s, 2m, 10m, 1h, 4h), set maximum attempt thresholds, and route exhausted payloads to Amazon SQS or RabbitMQ for manual replay and audit logging.
Read Retry Logic GuideAdvanced Error Mapping & Payload Transformation
Handle non-2xx responses gracefully without losing event context. Map HTTP 4xx/5xx status codes to custom retry policies, parse JSON error bodies from Stripe or GitHub, and use HookCheck’s transform middleware to normalize nested schemas before forwarding to your internal services.
Read Error Handling GuideStreaming Event Logs via WebSocket & Server-Sent Events
Replace polling with persistent connections for live debugging. Connect your dashboard to HookCheck’s `/ws/logs` endpoint, filter streams by environment tags (`prod-us-east`, `staging-eu-west`), and maintain sub-50ms latency for real-time payload inspection.
