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}

Recommended: webhook-handler-patterns

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
