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

For complete handlers with route wiring, event dispatch, and tests, see:
