Webhooks deserve a better workbench.
A webhook looks simple from a distance: something happens, a request is sent, and another system responds. The interesting part begins when those three steps stop lining up.
The event is the starting point.
A delivery log usually starts with an HTTP request. A developer often starts with a different question: what happened to this event? The same event might have several delivery attempts, each with a different outcome. Treating those attempts as unrelated rows makes the developer reconstruct the story by hand.
An event-first workbench can keep the original payload, delivery history, and destination together. The goal is straightforward: answer the next question without opening another tab.
A status code needs a little context.
A 200 response confirms that a server returned a successful HTTP response. It does not prove that the receiving application finished its work. A timeout is similarly ambiguous: the receiver may have processed the request even though the sender never saw the response.
Useful tooling preserves that distinction. Show what was sent, when it was sent, which response was observed, and what remains unknown. Clear language helps a developer decide whether to investigate, wait, or try again.
Replay is an engineering decision.
Replaying an event is useful when a receiver has been fixed or a delivery has failed. It can also repeat a side effect. The interface should make the destination and event identity visible before a replay, and the receiving application should use an appropriate idempotency strategy.
A workbench should retain the original event and append a new delivery attempt. That keeps the history understandable. An apparent success should never erase the failed attempts that explain why a replay was needed.
Bring the context together.
An event workbench should bring the payload, destination, and delivery history into a single context. Finding an event, reading its state, and choosing the next action should feel like parts of the same task.
The most valuable details are often ordinary ones: a stable event identity, a readable payload, a response tied to the attempt that produced it. Together, they give developers a reliable basis for investigation.
