Endpoints, requests & monitors

Built for real-world workflows

Whether you're debugging integrations, monitoring production, converting emails, or testing locally—Hooklistener has you covered.

Debug third-party integrations

Point Stripe, Shopify, or GitHub webhooks to a Debug Endpoint and watch payloads stream in live. Inspect headers, validate signatures, and replay failed requests to staging or prod.

Resolve issues 10x faster

Never miss broken webhooks

Configure Monitors on critical endpoints to get instant alerts when webhooks stop arriving. Receive notifications via Email or Slack before customers notice issues.

Catch failures before users do

Parse emails as webhooks

Convert order confirmations, notifications, and automated emails into HTTP webhooks. Create an Email Inbox and forward parsed data to any API endpoint automatically.

Save hours of manual parsing

Test webhooks locally

Use the CLI to tunnel live webhook traffic to your local development environment. No ngrok setup required—authenticate once and start receiving payloads instantly.

Start testing in under 30 seconds

Works with any HTTP source — Stripe, GitHub, Shopify, Twilio, and thousands more.

Powerful capabilities

Everything you need for webhook visibility

Inspect webhook deliveries, replay captured requests, and jump to our webhook debugger for deep payload troubleshooting when integrations break.

Custom Response Rules: configure status codes, headers, and response bodies for incoming webhook requests — ideal for testing retry logic and error handling.

Capture everything

Full HTTP capture including method, headers, body, query params, cookies, IP address, and TLS details. Nothing gets lost.

Inspect in real-time

Watch requests stream in live. Beautify JSON, validate signatures, search by content, and filter by source or status.

Learn more

Replay anywhere

Forward requests to production, staging, or localhost via CLI tunnel. Compare responses and debug with confidence.

Learn more

Share with your team

Generate shareable inspection links. Collaborate on debugging sessions without granting full account access.

Learn more

Instant alerts

Configure Monitors to detect silent integrations. Get notified via Email or Slack before issues impact users.

Learn more

Secure by default

TLS everywhere, encrypted storage, custom response codes to hide internals, and role-based access for teams.

Custom responses

Custom Webhook Responses

Define custom HTTP status codes, headers, and response bodies for every webhook endpoint. Simulate real API behavior during testing — including delays, errors, and conditional logic.

1. Configure your endpoint

Pick an HTTP status, set response headers, and craft the JSON (or plain text) body you want returned to the caller.

2. Simulate real-world behavior

Add artificial latency or intermittent 5xx responses to validate your retry, timeout, and backoff logic end-to-end.

3. Ship with confidence

Use the same endpoint across local dev, CI, and staging. Swap response rules per environment without touching your code.

Frequently asked questions

What is a webhook?
A webhook is an HTTP callback that pushes event data to your endpoint the moment something happens. Instead of polling an API, the provider sends a signed POST payload to the URL you configure, letting services like Stripe, GitHub, or Slack keep your application in sync in real time.
What is Hooklistener?
Hooklistener is a complete webhook toolkit for developers. It combines Debug Endpoints for capturing and inspecting webhooks, Monitors for alerting when integrations go silent, Email Inboxes for converting emails to webhooks, and a CLI tool for tunneling payloads to your local development environment. Everything you need to debug, monitor, and forward webhooks.
What are Debug Endpoints?
Debug Endpoints are unique HTTPS URLs that capture every incoming HTTP request with full details—headers, body, query params, IP address, and TLS information. You can inspect requests in real-time, replay them to any destination, share inspection links with teammates, and keep up to 60 days of history on paid plans. They're perfect for debugging third-party integrations without touching your production code.
How do Monitors work?
Monitors watch your Debug Endpoints for inactivity and send alerts when webhooks stop arriving. You configure a timeout threshold (1-1440 minutes), and if no requests arrive within that window, Hooklistener notifies you via Email and/or Slack. Cooldown periods prevent alert spam, and you can track alert history and last-request timestamps to diagnose issues quickly.
What are Email Inboxes?
Email Inboxes let you create unique email addresses (like notifications@hookinbox.com) that automatically convert incoming emails into HTTP webhooks. When an email arrives, Hooklistener parses the content (from, to, subject, body, attachments) and forwards it to your configured HTTP endpoints. Perfect for automating workflows triggered by transactional emails, notifications, or alerts.
How does the CLI work?
The Hooklistener CLI lets you receive live webhook payloads on your local machine. After authenticating with a simple device code flow, you can create a tunnel that forwards requests from any Debug Endpoint to localhost. It works behind firewalls, requires no ngrok setup, and gives you full request details including headers, body, and cookies for local debugging.
Why do teams choose Hooklistener over webhook.site or Hookdeck?
Teams choose Hooklistener for the complete toolkit approach:
  • Debug Endpoints with up to 60-day retention, request replay, and team sharing—not just temporary request bins.
  • Monitors that alert you via Email and Slack when integrations break, before customers notice.
  • Email Inboxes that convert any email into webhooks for workflow automation.
  • CLI tunneling for local development without complex ngrok configurations.
Can I use Hooklistener for free?
Yes. The Free plan includes 1 Debug Endpoint with 1 day of request history—enough to get started and explore the platform. When you need more, the Pro plan adds unlimited requests, 10 endpoints, 14-day retention, CLI access, and Email Inboxes. Sign up free.
