What problem does it solve? Choosing the wrong Stripe API or using deprecated patterns leads to failed integrations, security vulnerabilities, and costly rewrites. This Skill routes every Stripe question to the correct current API and enforces critical rules before any payment code is written. ## Core Features & Use Cases - Integration Routing: Maps your use case (one-time payments, subscriptions, marketplaces, usage-based billing, tax, embedded finance) to the correct Stripe API with a decision table. - Deprecated API Prevention: 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 Enforcement: Covers restricted API keys, webhook signature verification, OAuth CSRF protection, and incident response for compromised keys. - Use Case: You are building a marketplace and unsure whether to use Express accounts or destination charges. The Skill routes you to Accounts v2 with the correct dashboard, fee, and liability configuration for your business model. ## Quick Start Ask the assistant to plan a Stripe integration for your business model, such as setting up subscriptions with a 14-day trial using Checkout Sessions.
