01Overview

Reqhaven is a deployed developer tool for inspecting incoming webhook requests in real time.

02The Problem

Webhook integrations are difficult to debug when request payloads, headers, and signatures disappear inside external systems or logs.

03My Role

I built and deployed the full-stack tool, including unique webhook inboxes, live request capture, payload inspection, request replay, and Stripe signature verification.

04Approach

A unique inbox captures requests at the debugging boundary; Fastify persists them in SQLite and WebSockets updates the React interface when new data arrives.

05Solution

The finished workflow lets developers receive a webhook request, inspect its payload, replay it, and verify Stripe signatures from one live interface.

06Technical Details

Request capture to interface

  1. 01Webhook request
  2. 02Fastify API
  3. 03SQLite persistence
  4. 04WebSocket event
  5. 05React interface
07Impact

Live request capture, payload inspection, replay, and Stripe signature verification in one deployed workflow.
