A webhook request viewer for the part after the request arrives
HookNexus helps you inspect headers, payloads, request history, and delivery timing so you can understand what the sender actually sent before changing your handler.
Why a request viewer matters
A lot of webhook bugs happen after the sender has already reached you. The request exists, but the handler still fails. A request viewer helps you inspect what actually arrived so you can compare the real payload and headers with what your code expected.
If you searched for a webhook viewer, a request inspector, or a webhook request inspector, this is usually the problem you are trying to solve: the request is already there, and now you need to understand it.
What a good request viewer should show
- The full request body, not just a partial event summary.
- Headers, query parameters, delivery timing, and repeated attempts.
- Enough history to compare multiple deliveries instead of treating each one as disposable.
- A path into replay or localhost forwarding once you know what the request contains.
- The kind of detail a webhook payload viewer or request inspector is expected to make obvious at a glance.
Use it for payload shape mismatches
If your handler expects one structure but the real event looks different, a request viewer usually tells you faster than generic logs.
Use it for header-dependent logic
This is useful when the bug depends on request metadata, retries, content type, or provider-specific headers rather than body data alone.
Use it before you replay or forward
Request viewing is often the step that tells you whether the next best move is replaying the saved delivery or sending it into localhost.
Request viewer vs provider dashboard
Provider dashboards are useful, but they keep you inside one sender's view of the event. A request viewer becomes more valuable when you want the same inspection workflow across Stripe, GitHub, Shopify, Slack, and generic webhook senders.
That is also why teams often describe the same need with different words such as webhook viewer, request inspector, or webhook payload viewer.
Request viewer vs request bin
If your main need is a public URL and a quick confirmation that the request arrived, start with a request bin. If the request is already present and your real problem is understanding payloads, headers, timing, or retries, the request viewer is the better mental model.
FAQ
What is the difference between a request viewer and a request bin?
A request bin is usually about getting a public URL and seeing that a request arrived. A request viewer is about understanding the request after capture: payload shape, headers, delivery timing, retries, and what your app should do next.
Do I need a request viewer if I already have provider logs?
Provider logs can help, but a dedicated request viewer is useful when you want one place to inspect the exact request across providers and connect it to replay or localhost debugging.
Is HookNexus closer to a webhook viewer or a request inspector?
It can serve as both. Some teams search for a webhook viewer, others call the same need a request inspector. In practice the workflow is the same: inspect the real request after capture and decide what to do next.
When should I move from request viewing to replay or localhost forwarding?
Move on when the request is already visible and the next question becomes how your own code handles it. That is where replay and localhost forwarding save more time than inspection alone.
