What problem does it solve? Stripe integrations involve many API choices and common pitfalls, such as picking Checkout Sessions versus PaymentIntents, configuring Connect accounts, or enabling automatic tax without an active registration. This Skill routes each integration question to the correct current Stripe API and flags deprecated patterns and security mistakes before they ship. ## Core Features & Use Cases - Integration Routing: Maps your use case (one-time payments, subscriptions, marketplaces, tax, Treasury) to the recommended Stripe API and a detailed reference file. - Deprecated API Guardrails: Blocks legacy patterns like the Charges API, Sources API, v1 Connect account types, and hardcoded payment_method_types, with migration paths to modern equivalents. - Security Best Practices: Covers restricted API keys, secrets vaults, webhook signature verification, CSP headers, OAuth state parameters, and incident response for compromised keys. - Use Case: You are building a SaaS app with subscriptions and need to collect sales tax. The Skill directs you to Billing APIs with Checkout Sessions, confirms your tax registration is active before enabling automatic_tax, and ensures you omit payment_method_types for dynamic payment methods. ## Quick Start Ask how to set up Stripe Checkout for a subscription with automatic tax collection and secure webhook handling.
