# Stripe Integration Expert

Comprehensive guidance for integrating Stripe payments including subscriptions, usage-based billing, webhooks, and multi-platform support (Next.js, iOS, Android, Flutter) with Supabase database synchronization.

> **Philosophy:** Use Stripe Checkout for simplicity, Payment Intents for customization. Always verify webhooks. For Supabase sync, prefer **Stripe Sync Engine** (one-click, zero maintenance) unless you need custom schemas. Never expose secret keys to clients.
