I added this feature to customize response headers. Please have a look if its what you had in mind. It is available only for logged in users when creating a new webhook or editing an existing one.

Thank you for the feedback. I will add a feature to customize response headers today.

Any other features you would like to see in the app?

Honestly no… testing them needn’t be a complex process!

There is another service that allows for scripting which I’m sure some people love, but I just need somewhere I can set the response.

I built a small tool to help debug and inspect webhooks more easily. It gives you a unique URL where you can see incoming requests, headers, payloads, and even replay them.

Built in Go, it’s lightweight, open source, and free to use.

Try it out: https://testwebhook.xyz

Code: https://github.com/muliswilliam/webhook-tester

Would love your feedback or suggestions!

This post falls under Show HN and should probably follow the guidelines (eg. title should begin with Show HN:). See https://news.ycombinator.com/showhn.html

Tool itself looks interesting and I've been looking for something like this several times. I'm bookmarking it for next time.

Thank you, I will post it in show HN

I didn't see any sort of license in the repository. If your intention is that people can self-host, it would be nice to include some sort of license so that it's clear what the terms of use are for self-hosting.

Neat looking project! Thanks for sharing!
