Test and debug webhooks with Hookdeck Inspect. Get a live URL you and your agent can use, plus mock webhooks for 500+ providers. It's free, no account or setup required.
Request bins have been around for ages, but were built for humans. We thought it time to build something agent-native.
Inspect is a webhook tester you can use with your agent. No skills, MCP, or server setup required.
Get a URL and see requests arrive live, with payloads exactly as sent. Or paste the URL into Claude or Codex and it’ll tell you when a request lands, and use it to build your handler.
What's included:
Mock webhooks from 500+ providers, including Stripe, Shopify and GitHub
A live request feed that you and your agent can use
A path to production: forward to localhost with CLI, then move to Event Gateway for queues, retries and transforms.

This is smart, and I love to see something not entirely dripping in AI for once
Hookdeck is pretty awesome. TBH webhooks have always been a thorn in our sides, so any attempts to make the problem suck less is greatly appreciated!
Every DM in StorkPlus reaches our agents as a Meta webhook, and the slow part is messaging our own test page just to see one payload again. Does the mock list cover WhatsApp, Messenger and Instagram events? And can an Inspect URL answer Meta's hub.challenge verification, so I can point a real test app at it too?
Nice idea making a request bin that the agent can read too. Do the mock webhooks from the 500+ providers include valid signatures, so I can test signature verification in my handler, or just the payload shape?
The bit that stands out to me is the path to production — most test bins are a dead end, but here you can forward to localhost with the CLI and then graduate the same flow to Event Gateway for queues and retries. Also like that you can paste the URL into Claude or Codex and have the agent tell you when a request actually lands, instead of me babysitting a refresh button.
a live url i can hand to an agent without setting up a server is handy
the provider examples should also save that awkward step of waiting for a real event just to check the payload shape
Mock payloads for 500 plus providers is the part that saves real time, because most of my webhook debugging is spent getting a provider to fire the one event I actually need to see.
