Webhooks fail silently. The provider sent the payload, your endpoint returned 200, but your handler stopped processing it three versions ago. Nobody noticed until a customer complained.
Hooklistener monitors watch your endpoints for inactivity — not just uptime. If expected webhooks stop arriving, you get an alert before your customers notice.
Monitors are attached to your Debug Endpoints. Configure the threshold, pick your alert channels, and stop worrying about silent failures.
Set the silence window that triggers an alert — from 1 minute to 24 hours. Match the threshold to how frequently each provider sends webhooks.
Get notified where your team already works. Configure one or both channels per monitor. Alerts include the endpoint name, last-seen timestamp, and threshold.
Prevent alert fatigue. After an alert fires, the cooldown suppresses duplicate notifications for a configurable period.
When webhooks resume, Hooklistener logs the recovery event. Full timeline: when silence started, when the alert fired, and when traffic came back.
Route alerts to the right people. Send Stripe alerts to the payments team, GitHub alerts to platform eng. Not everything goes to the same channel.
Every alert and recovery is logged. Track patterns over time — which integrations are flaky, how long outages last, and whether your thresholds need tuning.
Uptime monitors ping your server to see if it responds. Inactivity monitors watch real webhook traffic to see if your integration is actually working. They catch different failures.
| Uptime Monitoring | Inactivity Monitoring | |
|---|---|---|
| What it watches | Whether your server responds to synthetic pings | Whether real webhook traffic is still arriving from your providers |
| Catches | Server crashes, DNS failures, network outages | Broken handlers, provider-side failures, silent config changes, expired API keys |
| Blind spot | Your server is up but your Stripe handler has been silently broken for a week | None — if webhooks stop, you know |
| Alert trigger | Endpoint returns non-2xx or times out | No webhook received within your configured threshold |
| False positives | High — transient network blips, maintenance windows | Low — if your provider is sending and your endpoint is healthy, traffic flows |
Monitors watch for silence, not errors. If expected webhooks stop arriving within your configured threshold, you get an alert.
Pick any Debug Endpoint and set an inactivity threshold — the window of silence that triggers an alert. Thresholds range from 1 minute to 24 hours.
Get alerted via Email, Slack, or both. Alerts go to the people who can actually fix the problem — not a noisy shared channel.
Prevent alert spam. After an alert fires, the cooldown suppresses duplicate notifications for a configurable period so your team isn't buried in noise.
When webhooks start arriving again, Hooklistener logs the recovery event. You get a full timeline: when it went silent, when the alert fired, and when it recovered.
Move from one-off bins to a production-grade webhook platform with replay, forwarding, and monitoring built in. Compare features side-by-side and migrate in minutes.
Persist webhook history for 14+ days, search instantly, and replay to any environment.
Send events to QA, staging, and production with conditional routing and transformations.
Invite collaborators, mask secrets, and stay audit-ready—no public bins or shared tokens.
Why not just use PagerDuty or Datadog?
Those tools monitor your infrastructure — servers, containers, error rates. Hooklistener monitors your webhook integrations specifically. It knows when Stripe stopped sending, not just when your CPU spiked.
Can I monitor webhooks from any provider?
Yes. Any webhook that hits your Hooklistener endpoint is monitored. Stripe, GitHub, Shopify, Twilio, or your own internal services.
Is this included in the free plan?
Monitors are available on Pro ($12/mo) and Team ($20/mo) plans. The free plan includes a Debug Endpoint with request history to get started.
Connect Claude Code, Cursor, or Codex to Hooklistener's MCP server and your agent gets 46 tools for endpoints, requests, automations, schedules, and email. You get the same data live in the dashboard.
Free plan includes MCP access. No credit card required.
