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

Express Webhook Handler

```javascript

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

```python

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}

```

| Event | Description |

|-------|-------------|

| payment_intent.succeeded | Payment completed successfully |

| 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 |

```bash

STRIPE_SECRET_KEY=sk_test_xxxxx # From Stripe dashboard

STRIPE_WEBHOOK_SECRET=whsec_xxxxx # From webhook endpoint settings

```

```bash

# Install Hookdeck CLI for local webhook testing

brew install hookdeck/hookdeck/hookdeck

# Start tunnel (no account needed)

hookdeck listen 3000 --path /webhooks/stripe
