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}

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
