Use case · API Integrations

Ship webhook integrations in a day, not a week.

Every new provider integration starts with the same questions: what does the payload look like, how do I verify signatures, what events fire when? HookSense answers all three in 30 seconds.

What's painful today

  • Provider docs describe payloads in the abstract — the actual bytes (header order, field names, encoding) only show up in real events.
  • Signature verification is the #1 webhook bug: wrong algorithm, wrong header, wrong body encoding. Catching it after deploy is expensive.
  • Integrations with 5+ providers mean 5+ different signing schemes, payload shapes, and retry behaviors to learn from scratch.

How HookSense solves it

Auto-detect provider and event

HookSense identifies Stripe, GitHub, Shopify, Slack, Twilio, SendGrid, and more from headers alone — and tags every request with the event type (`checkout.session.completed`, `push`, `orders/create`).

Verify signatures with one click

Drop in the signing secret; HookSense verifies every signature in real time — Stripe, GitHub, Shopify, custom HMAC. Failed verifications are highlighted so you can debug encoding, not crypto.

One UI for every provider

Stop context-switching between Stripe Dashboard, GitHub Webhooks page, and Shopify admin. Every captured request looks the same in HookSense, so you build pattern matching once.

See it in code

Verify a Stripe signature in your handler

// HookSense already verifies signatures in the UI for live debugging.
// In production, mirror the same verification logic in your handler:

import { createHmac, timingSafeEqual } from "crypto";

function verifyStripe(body: string, header: string, secret: string) {
  const [t, v1] = header.split(",").map(p => p.split("=")[1]);
  const expected = createHmac("sha256", secret)
    .update(`${t}.${body}`)
    .digest("hex");
  return timingSafeEqual(Buffer.from(v1), Buffer.from(expected));
}

FAQ

Which providers does HookSense support out of the box?

Auto-detection and signature verification ship for Stripe, GitHub, Shopify, Slack, Twilio, SendGrid, Clerk, and LemonSqueezy. Any other provider works — you just configure the signature scheme manually.

Can I use HookSense for outbound webhooks too?

HookSense is focused on inbound webhook inspection. For outbound delivery (you're the sender), look at Hookdeck or Svix. The Replay feature lets you re-send captured webhooks, which covers most retry/forwarding use cases.

How do I document the integration after it's working?

Export any captured request as cURL, JSON, or a code snippet. Drop these into your integration docs as canonical examples — they'll always reflect real provider behavior.
