What is Webhook Tester?
NewKit's webhook tester generates a unique, temporary URL you can point any webhook-sending service to. Every request that arrives —GET, POST or any method— is captured instantly and shown with its method, headers, query string and body, without you having to deploy a single server.
It is the fastest way to debug integrations from Stripe, GitHub, Shopify, Zapier or any form: point the webhook at your URL, fire the event and see exactly what is being sent. The URL is ephemeral (requests are kept for 2 hours) and runs on Cloudflare Workers, so capture is virtually instant from anywhere in the world.
Frequently asked questions
Is it free?
Yes, all NewKit tools are completely free.
How does it work without installing anything?
The tool runs on Cloudflare Workers at the edge: your browser makes a lightweight request to our server, which performs the network lookup and returns the result. There is nothing to configure.
Is there a usage limit?
To keep the service free and within Cloudflare's free tier, we apply a reasonable daily request limit. For normal use you will not notice it.
