Use when integrating Stripe payments, building subscription systems, or implementing secure checkout flows. Stripe Integration Master Stripe payment processing integration for robust, PCI-compliant payment flows including checkout, subscriptions, webhooks, and refunds. When to Use This Skill Implementing payment processing in web/mobile applications Setting up subscription billing systems Handling one-time payments and recurring charges Processing refunds and disputes Managing customer payment methods Implementing SCA (Strong Customer Authentication) for European payments Building marketplace payment flows with Stripe Connect Core Concepts 1. Payment Flows Checkout Sessions Recommended for most integrations Supports all UI paths: Stripe-hosted checkout page Embedded checkout form Custom UI with Elements (Payment Element, Express Checkout Element) using ui_mode='custom' Provides built-in checkout capabilities (line items, discounts, tax, shipping, address collection, saved payment methods, and checkout lifecycle events) Lower integration and maintenance burden than Payment Intents Payment Intents (Bespoke control) You calculate the final amount with taxes, discounts, subscriptions, and currency conversion yourself. More complex implementation and long-term maintenance burden Requires Stripe.js for PCI compliance Setup Intents (Save Payment Methods) Collect payment method without charging Used for subscriptions and future payments Requires customer confirmation 2. Webhooks Critical Events: payment_intent.succeeded : Payment completed payment_intent.payment_failed : Payment failed customer.subscription.updated : Subscription changed customer.subscription.deleted : Subscription canceled charge.refunded : Refund processed invoice.payment_succeeded : Subscription payment successful 3. Subscriptions Components: Product : What you're selling Price : How much and how often Subscription : Customer's recurring payment Invoice : Generated for each billing cycle 4. Customer Management Create and manage customer records Store multiple payment methods Track customer metadata Manage billing details Quick Start import stripe stripe.api_key = "sk_test_..." # Create a checkout session session = stripe.checkout.Session.create( line_items=[{ 'price_data' : { 'currency' : 'usd' , 'product_data' : { 'name' : 'Premium Subscription' , }, 'unit_amount' : 2000 , # $20.00 'recurring' : { 'interval' : 'month' , }, }, 'quantity' : 1 , }], mode= 'subscription' , success_url= 'https://yourdomain.com/success?session_id={CHECKOUT_SESSION_ID}' , cancel_url= 'https://yourdomain.com/cancel' ) # Redirect user to session.url print (session.url) Detailed patterns and worked examples Detailed pattern documentation lives in references/details.md . Read that file when the navigation tier above is insufficient. Testing # Use test mode keys stripe.api_key = "sk_test_..." # Test card numbers TEST_CARDS = { 'success' : '4242424242424242' , 'declined' : '4000000000000002' , '3d_secure' : '4000002500003155' , 'insufficient_funds' : '4000000000009995' } def test_payment_flow (): """Test complete payment flow.""" # Create test customer customer = stripe.Customer.create( email= "test@example.com" ) # Create payment intent intent = stripe.PaymentIntent.create( amount= 1000 , automatic_payment_methods={ 'enabled' : True }, currency= 'usd' , customer=customer. id ) # Confirm with test card confirmed = stripe.PaymentIntent.confirm( intent. id , payment_method= 'pm_card_visa' # Test payment method ) assert confirmed.status == 'succeeded'
