Lo que puedes crear

E-commerce Checkout Integration

Build secure checkout flows with Stripe Elements or PayPal buttons, including cart total validation and order confirmation webhooks.

Subscription Billing System

Implement recurring payment logic with proper handling of trial periods, proration, failed payment retries, and cancellation flows.

Payment Webhook Handler

Create robust webhook endpoints that verify signatures, ensure idempotency, and handle payment events like successful charges and disputes.

Prueba estos prompts

Basic Stripe Checkout Setup 
Help me create a basic Stripe checkout integration for my e-commerce site. I need a payment form using Stripe Elements, server-side payment intent creation, and webhook handling for successful payments.
Subscription with Trial Period 
I need to implement a subscription plan with a 14-day free trial using Stripe Billing. Show me how to create the subscription, handle the trial period, and process the first payment when the trial ends.
Webhook Security Implementation 
Create a secure webhook endpoint for Stripe that verifies signatures, checks for duplicate events, and handles payment_intent.succeeded and charge.disputed events. Include database storage for processed event IDs.
Multi-Provider Payment Gateway 
I need to support both Stripe and PayPal checkout options. Design an abstraction layer that allows switching between providers, with unified payment confirmation handling and error reporting.

Mejores prácticas

  • Always verify webhook signatures using official SDK methods before processing any payment events
  • Implement idempotency by storing processed event IDs to prevent duplicate order fulfillment
  • Use tokenization (Stripe Elements, PayPal SDK) to avoid handling raw card data and reduce PCI scope

Evitar

  • Never store raw credit card numbers, CVV codes, or full magnetic stripe data in your database
  • Do not skip webhook signature verification even in development environments
  • Avoid processing webhooks synchronously for expensive operations - return 200 OK quickly then process asynchronously

Preguntas frecuentes

What payment processors does this skill support?
This skill provides integration guidance for Stripe, PayPal, and Square. Stripe is recommended for most use cases due to excellent documentation and developer experience.
Do I need PCI compliance to use this skill?
When using tokenization (Stripe Elements, PayPal SDK), your PCI scope is significantly reduced to SAQ-A. You still need basic compliance but do not handle raw card data directly.
How do I test payment integrations without charging real cards?
All payment providers offer test mode with test API keys and test card numbers. Use test mode during development and only switch to live keys when ready for production.
What happens if a webhook is delivered multiple times?
Payment providers retry webhooks that do not receive a 2xx response. Implement idempotency by storing event IDs and checking before processing to prevent duplicate orders.
Can this skill handle refunds and disputes?
Yes, it provides code patterns for processing refunds through payment provider APIs and handling dispute webhooks with proper notification and record keeping.
How do I handle subscription plan changes and proration?
The skill generates code for Stripe Billing subscription updates with proration behavior configuration, including immediate charges or credits at next billing cycle.
