Payment Integration & Billing
Integrates Stripe, PayPal, and Square payment gateways with a focus on security, PCI compliance, and robust webhook handling.
The Payment Integration skill empowers Claude to architect and implement secure financial workflows using industry-leading providers like Stripe and PayPal. It provides domain-specific guidance on building checkout flows, managing recurring subscriptions, and implementing critical security measures such as webhook signature verification and request idempotency. By enforcing PCI compliance best practices—such as never handling raw card data—this skill ensures that developers build reliable, production-ready billing systems that handle edge cases, failed payments, and asynchronous events effectively.
