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

Verification (core)

Stripe ships official SDK helpers that verify the Stripe-Signature header (HMAC-SHA256 over timestamp.body) and parse the event in one call. Pass the raw request body — don't JSON.parse first.

Node:

const stripe = require('stripe')(process.env.STRIPE_SECRET_KEY);

const event = stripe.webhooks.constructEvent(
  rawBody,                                  // Buffer or string of the raw HTTP body
  req.headers['stripe-signature'],
  process.env.STRIPE_WEBHOOK_SECRET         // whsec_… from the webhook endpoint settings
);
// Throws Stripe.errors.SignatureVerificationError on tampering or stale timestamp

Python:

import stripe

event = stripe.Webhook.construct_event(
    raw_body,                                 # bytes of the raw HTTP body
    request.headers["stripe-signature"],
    os.environ["STRIPE_WEBHOOK_SECRET"],
)
# Raises stripe.error.SignatureVerificationError on tampering or stale timestamp

Environment Variables

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

Local Development

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
