Use when integrating Stripe payments, building subscription systems, or implementing secure checkout flows.</h2>\n<h1>Stripe Integration</h1>\n<p>Master Stripe payment processing integration for robust, PCI-compliant payment flows including checkout, subscriptions, webhooks, and refunds.</p>\n<h2>When to Use This Skill</h2>\n<ul>\n<li>Implementing payment processing in web/mobile applications</li>\n<li>Setting up subscription billing systems</li>\n<li>Handling one-time payments and recurring charges</li>\n<li>Processing refunds and disputes</li>\n<li>Managing customer payment methods</li>\n<li>Implementing SCA (Strong Customer Authentication) for European payments</li>\n<li>Building marketplace payment flows with Stripe Connect</li>\n</ul>\n<h2>Core Concepts</h2>\n<h3>1. Payment Flows</h3>\n<p><strong>Checkout Sessions</strong></p>\n<ul>\n<li>Recommended for most integrations</li>\n<li>Supports all UI paths:\n<ul>\n<li>Stripe-hosted checkout page</li>\n<li>Embedded checkout form</li>\n<li>Custom UI with Elements (Payment Element, Express Checkout Element) using <code>ui_mode='custom'</code></li>\n</ul>\n</li>\n<li>Provides built-in checkout capabilities (line items, discounts, tax, shipping, address collection, saved payment methods, and checkout lifecycle events)</li>\n<li>Lower integration and maintenance burden than Payment Intents</li>\n</ul>\n<p><strong>Payment Intents (Bespoke control)</strong></p>\n<ul>\n<li>You calculate the final amount with taxes, discounts, subscriptions, and currency conversion yourself.</li>\n<li>More complex implementation and long-term maintenance burden</li>\n<li>Requires Stripe.js for PCI compliance</li>\n</ul>\n<p><strong>Setup Intents (Save Payment Methods)</strong></p>\n<ul>\n<li>Collect payment method without charging</li>\n<li>Used for subscriptions and future payments</li>\n<li>Requires customer confirmation</li>\n</ul>\n<h3>2. Webhooks</h3>\n<p><strong>Critical Events:</strong></p>\n<ul>\n<li><code>payment_intent.succeeded</code>: Payment completed</li>\n<li><code>payment_intent.payment_failed</code>: Payment failed</li>\n<li><code>customer.subscription.updated</code>: Subscription changed</li>\n<li><code>customer.subscription.deleted</code>: Subscription canceled</li>\n<li><code>charge.refunded</code>: Refund processed</li>\n<li><code>invoice.payment_succeeded</code>: Subscription payment successful</li>\n</ul>\n<h3>3. Subscriptions</h3>\n<p><strong>Components:</strong></p>\n<ul>\n<li><strong>Product</strong>: What you're selling</li>\n<li><strong>Price</strong>: How much and how often</li>\n<li><strong>Subscription</strong>: Customer's recurring payment</li>\n<li><strong>Invoice</strong>: Generated for each billing cycle</li>\n</ul>\n<h3>4. Customer Management</h3>\n<ul>\n<li>Create and manage customer records</li>\n<li>Store multiple payment methods</li>\n<li>Track customer metadata</li>\n<li>Manage billing details</li>\n</ul>\n<h2>Quick Start</h2>\n<pre><code>import stripe\n\nstripe.api_key = \"sk_test_...\"\n\n# Create a checkout session\nsession = stripe.checkout.Session.create(\n    line_items=[{\n        'price_data': {\n            'currency': 'usd',\n            'product_data': {\n                'name': 'Premium Subscription',\n            },\n            'unit_amount': 2000,  # $20.00\n            'recurring': {\n                'interval': 'month',\n            },\n        },\n        'quantity': 1,\n    }],\n    mode='subscription',\n    success_url='https://yourdomain.com/success?session_id={CHECKOUT_SESSION_ID}',\n    cancel_url='https://yourdomain.com/cancel'\n)\n\n# Redirect user to session.url\nprint(session.url)\n</code></pre>\n<h2>Detailed patterns and worked examples</h2>\n<p>Detailed pattern documentation lives in <code>references/details.md</code>.
