Replay saved webhook requests without touching the provider again
HookNexus lets you capture a real delivery once, inspect it in the dashboard, and replay the saved request to your connected client when you need another test pass.
Why replay matters
A lot of webhook debugging time is wasted recreating the same provider action after every code change. Replay shortens that loop. You capture the real request once, keep the payload and headers available in HookNexus, and resend the saved delivery when you want another validation pass.
A practical replay workflow
- Capture a real delivery from Stripe, GitHub, Shopify, Slack, or another webhook sender.
- Inspect the saved request in HookNexus so you know the body, headers, and timing look correct.
- Connect the client you want to test, such as a local CLI forwarding target or another supported downstream client.
- Replay the saved request when your handler changes and you want another pass without recreating the original event.

Use replay when the original event is expensive to recreate
This is common with payment flows, store actions, or complex bot triggers where reproducing the same event again takes time or changes external state.
Use replay when your code changed but the payload did not
If the request itself is still valid and you only want to validate a new handler version, replay is usually the fastest route to another test.
Use replay with localhost forwarding
Replay becomes especially useful once the same saved request can be sent back into your local debugging loop instead of living as a read-only record in the dashboard.
What replay is best at
- Re-testing a real request after changing your handler logic.
- Comparing how the same payload behaves before and after a code fix.
- Keeping debugging momentum when the upstream provider action is slow, manual, or hard to reproduce.
What replay does not replace
- Replay does not create a new upstream provider event.
- Replay does not change the original business state in Stripe, GitHub, Shopify, Slack, or another sender.
- Replay is best for validating your handling workflow after capture, not for simulating every possible provider-side change.

FAQ
Do I need to trigger the provider again every time I change my handler?
No. That is the main reason replay exists. Once the original request is captured, you can resend the saved delivery instead of recreating the same provider action.
Is replay useful if my app is still running locally?
Yes. Replay is especially useful after you connect localhost forwarding or another client and want to validate code changes against the same request again.
Does replay create a new provider event?
No. Replay resends the saved request from HookNexus. It helps you re-test your own handling workflow, not create a brand new upstream event in Stripe, GitHub, Shopify, Slack, or another provider.
