Stripe Webhooks

When to Use This Skill

• Setting up Stripe webhook handlers
• Debugging signature verification failures
• Understanding Stripe event types and payloads
• Handling payment, subscription, or invoice events

Essential Code (USE THIS)

Express Webhook Handler

const express = require("express");
const stripe = require("stripe")(process.env.STRIPE_SECRET_KEY);

const app = express();

// CRITICAL: Use express.raw() for webhook endpoint - Stripe needs raw body
app.post("/webhooks/stripe", express.raw({ type: "application/json" }), async (req, res) => {
  const signature = req.headers["stripe-signature"];

  let event;
  try {
    // Verify signature using Stripe SDK
    event = stripe.webhooks.constructEvent(
      req.body,
      signature,
      process.env.STRIPE_WEBHOOK_SECRET // whsec_xxxxx from Stripe dashboard
    );
  } catch (err) {
    console.error("Stripe signature verification failed:", err.message);
    return res.status(400).send(`Webhook Error: ${err.message}`);
  }

  // Handle the event
  switch (event.type) {
    case "payment_intent.succeeded":
      console.log("Payment succeeded:", event.data.object.id);
      break;
    case "customer.subscription.created":
      console.log("Subscription created:", event.data.object.id);
      break;
    case "invoice.paid":
      console.log("Invoice paid:", event.data.object.id);
      break;
    default:
      console.log("Unhandled event:", event.type);
  }

  res.json({ received: true });
});

Python (FastAPI) Webhook Handler

import stripe
from fastapi import FastAPI, Request, HTTPException

stripe.api_key = os.environ.get("STRIPE_SECRET_KEY")
webhook_secret = os.environ.get("STRIPE_WEBHOOK_SECRET")

@app.post("/webhooks/stripe")
async def stripe_webhook(request: Request):
    payload = await request.body()
    signature = request.headers.get("stripe-signature")

    try:
        event = stripe.Webhook.construct_event(payload, signature, webhook_secret)
    except stripe.error.SignatureVerificationError:
        raise HTTPException(status_code=400, detail="Invalid signature")

    # Handle event...
    return {"received": True}

payment_intent.payment_failed	Payment failed
customer.subscription.created	New subscription started
customer.subscription.deleted	Subscription canceled
invoice.paid	Invoice payment successful
checkout.session.completed	Checkout session finished

For full event reference, see Stripe Webhook Events

Environment Variables

STRIPE_SECRET_KEY=sk_test_xxxxx      # From Stripe dashboard
STRIPE_WEBHOOK_SECRET=whsec_xxxxx    # From webhook endpoint settings

Local Development

# Install Hookdeck CLI for local webhook testing
brew install hookdeck/hookdeck/hookdeck

# Start tunnel (no account needed)
hookdeck listen 3000 --path /webhooks/stripe

We recommend installing the webhook-handler-patterns skill alongside this one for handler sequence, idempotency, error handling, and retry logic. Key references (open on GitHub):

• Handler sequence — Verify first, parse second, handle idempotently third
• Idempotency — Prevent duplicate processing
• Error handling — Return codes, logging, dead letter queues
• Retry logic — Provider retry schedules, backoff patterns
