Add Webhooks Automatically
Example session with this skill installed
Add an incoming Stripe webhook handler to my Express app to handle 'checkout.session.completed' events. Ensure it verifies signatures and uses the existing Redis queue for processing.
- Read your context and instructions
- Compiled the add webhooks automatically
Project Detected: Node.js / Express
Webhook Integration Added
- Stripe
- Incoming
- checkout.session.completed
Security Controls
- stripe-signature verification via raw-body middleware
- STRIPE_WEBHOOK_SECRET env reference
Reliability Controls
- Idempotency check via event ID
- Processing offloaded to BullMQ queue
Files Modified
- src/routes/webhooks.js
- src/middleware/verifyStripe.js
- .env.example
Commands Executed
- npm install stripe
Validation Result
Signature logic and route parsing verified with local mock.
How to Test
npm test src/routes/webhooks.test.js

About this skill
The problem
Integrating webhooks manually often leads to insecure endpoints, missing signature verification, and race conditions. Developers frequently struggle with idempotency, handling retries, and keeping secrets out of version control.
What it does
- Detects your application stack and routing conventions to scaffold native webhook handlers.
- Implements mandatory signature verification and raw body preservation for secure provider handshakes.
- Adds idempotency logic and event ID tracking to prevent duplicate processing.
- Configures outgoing webhook retries with bounded backoff and configurable timeouts.
- Generates environment variable placeholders and updates test suites without hardcoding secrets.
Frameworks & tools
Works with any stack including Node.js (Express, NestJS), Python (FastAPI, Django), Ruby on Rails, and PHP. Supports integrations for Stripe, GitHub, Slack, Shopify, and custom providers.
Why this beats prompting it yourself
Standard LLMs often overlook the nuances of webhook security, such as raw body requirements for HMAC verification or the need for background task offloading. This skill enforces a security-first architecture, ensuring your endpoints aren't just functional, but production-ready and resilient to failures.
Use cases
- Adding a Stripe checkout completion handler with signature verification.
- Building a GitHub App that responds to push events via repository webhooks.
- Setting up reliable outgoing Slack notifications with automated retries.
- Repairing a broken webhook integration that lacks proper error handling.
Known limitations
Requires an existing project structure to detect conventions. Cannot verify external delivery without user-provided sandbox credentials.
