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
HookSense is the callback layer for AI agents: an agent calls create_callback_endpoint, awaits the result with wait_for_callback, and trusts it because verify_signature already checked 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_signature, no crypto in your code
Drop in the signing secret; HookSense verifies every signature — Stripe, GitHub, Shopify, custom HMAC — and your agent or handler gets the result via `verify_signature` over MCP. Failed verifications are highlighted so you 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 the inbound callback layer — an agent or app creates an endpoint and awaits results sent to it. For outbound delivery at scale (you're the sender, fanning out to many consumers), look at Hookdeck or Svix. The replay_callback tool lets you re-send any captured callback, which covers most retry and re-forwarding needs.
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.
Give your agent a callback URL in 30 seconds.
