HookLab Lifetime Deal
Webhooks are supposed to make integrations seamless, but when something goes wrong, finding the cause isn’t always straightforward. A payment may not update, a notification might not arrive, or an automation may simply not run—even if the provider indicates that the webhook was successfully delivered. Without seeing the actual request that reached your application, you’re left digging through logs and making educated guesses.
The biggest challenge is that many debugging tools don’t show the complete picture. Missing headers, invalid signatures, unexpected payloads, or formatting differences can all cause integrations to fail. Recreating those exact requests manually takes time, slows development, and can turn a simple bug into hours of frustrating troubleshooting.
HookLab simplifies webhook debugging by showing you exactly what your application receives. Create a webhook endpoint in seconds, capture incoming requests in real time, inspect headers and payloads, verify signatures, and replay the same request whenever you need to test a fix. Instead of trying to reproduce an issue from scratch, you can work with the original request and resolve problems much faster.
Whether you’re integrating Stripe, GitHub, payment gateways, or your APIs, HookLab gives you the tools to debug with confidence. From one-click request replay to built-in signature verification and privacy-focused request handling, everything is designed to help developers spend less time troubleshooting and more time building reliable applications.
Why Choose HookLab?
Webhook integrations often fail for reasons that are difficult to identify. Missing headers, invalid signatures, unexpected payloads, or formatting differences can consume hours of debugging.
HookLab removes the guesswork by showing every incoming request exactly as it arrives. You can inspect headers, query parameters, JSON bodies, and replay captured events against your local, staging, or production environments. Whether you’re testing Stripe, GitHub, payment gateways, or custom APIs, HookLab provides everything you need to troubleshoot webhooks quickly and confidently.

HookLab is a developer-friendly webhook inspection and replay platform that helps you capture incoming requests, validate webhook signatures, inspect raw payloads, and replay events without rebuilding test environments.
Key Features
- Capture Every Incoming Webhook: Generate a unique webhook endpoint instantly and inspect every request as it arrives. View HTTP methods, headers, query parameters, and request bodies without additional setup.
- Replay Requests with One Click: Resend captured webhook events to localhost, staging, or production environments. Reproduce issues consistently without asking external services to trigger events again.
- Verify Webhook Signatures: Built-in verification for Stripe and GitHub signatures helps ensure your webhook requests are authentic and haven’t been modified during transmission.
- Inspect Raw Payloads: See webhook data exactly as it was received. Pretty-printed JSON makes large payloads easy to read while preserving the original request for accurate debugging.
- Create Unlimited Endpoints: Organize multiple projects using dedicated webhook endpoints, making it easier to separate development, testing, and production workflows.
- Custom Response Simulation: Return custom HTTP status codes or delayed responses to test retry logic and error-handling behavior before deployment.
- Replay Across Any Environment: Forward captured requests to local development servers, QA environments, staging, or live applications with identical payloads.
- Privacy-First Request Handling: Sensitive headers like Authorization, Cookies, and API keys are automatically excluded before storage, helping protect confidential information.
- White-Label Endpoints: Use your own custom domain for webhook endpoints to provide a more professional experience for internal teams and clients.
- Developer-Friendly Dashboard: Monitor requests in real time through a clean interface designed to help developers quickly identify payload issues, header mismatches, and integration failures.
Use Cases
- Debug Payment Webhooks: Quickly troubleshoot Stripe payment events, subscription updates, refunds, and checkout notifications without waiting for another transaction.
- Test GitHub Webhooks: Capture repository events, verify signatures, and replay requests while building GitHub Apps or CI/CD workflows.
- Validate Third-Party Integrations: Inspect webhook payloads from CRMs, marketing tools, payment gateways, and automation platforms before they reach your application.
- Improve Local Development: Replay production webhook events directly to your localhost to reproduce bugs without affecting live systems.
- Test Error Handling: Return custom HTTP responses and delays to verify retry mechanisms, fallback logic, and webhook resilience.
- Support Client Integrations: Provide branded webhook endpoints using your own domain for agencies managing integrations across multiple client projects.
