Vercel webhooks
Test and debug Vercel webhooksfor deployments and builds
Capture deployment created, succeeded and failed events as Vercel sends them, and build release notifications on real payloads.
See every Vercel deployment event
Vercel webhooks power deployment notifications, build monitoring and release automation. When webhook events fail, teams ship without knowing a deploy broke.
Hooklistener keeps every Vercel request with its headers and body. Follow a deployment from start to finish, read the signature header your code checks, and use replay (Pro) to test your automation.
Vercel webhook challenges
Deployment tracking gaps
A build started but you never saw it finish. You need every deployment event for that build in one place.
Signature validation issues
Vercel's webhook signature check fails in your handler without saying why.
Multi-environment noise
Preview and production deployments arrive on the same webhook, and the event you care about gets buried.
How Hooklistener helps with Vercel webhooks
Raw body and headers for your signature check
See the exact body and signature header Vercel sent, so you can find out why your own verification code rejects a deployment event.
Search Vercel events by environment
Search the request history for a Vercel deployment ID or target, and keep saved filters (Pro) for production deploys so preview events stop burying them.
Inactivity monitors for deployments
Get an email, Slack or signed-webhook alert when Vercel deployment events stop arriving, so a build that started but never finished does not go unnoticed.
Try it: point Vercel at a free webhook URL or run a test with the webhook tester.
Vercel automation workflows
Release notifications
Tell the team about production deployments in Slack, Discord or a custom dashboard.
Quality gates
Trigger end-to-end tests, Lighthouse checks or security scans on preview deployments.
Incident response
Follow failed deployments and rollbacks, and alert on-call engineers when a production build fails.
Replay a failed webhook without re-triggering the provider
Once a delivery is captured, you can resend its exact headers and body to localhost, staging or production from the dashboard or through your coding agent over MCP, so the provider never has to fire a new event. Replay is on Pro and above. Read the replay guide.

Frequently asked questions
Does Hooklistener validate Vercel signatures?
No. Built-in signature verification covers Stripe, GitHub and Slack. Hooklistener keeps the raw body and Vercel's signature header so you can check your own verification code against the exact request.
Can I see preview deployments?
Yes. Every deployment event Vercel sends to the endpoint is captured, and you can search the history by branch, commit or environment.
Do you capture domain events?
Hooklistener captures any event Vercel sends to the endpoint, so the events you subscribe to show up in the history.
Can I replay deployment events?
Yes. Replay is on Pro and above. Resend a captured Vercel event to test notifications or quality gates.
Know when a Vercel deploy breaks
Capture and inspect every Vercel deployment event, and get alerted when they stop.
