Master Stripe payment processing integration for robust, PCI-compliant payment flows including checkout, subscriptions, webhooks, and refunds.

When to Use This Skill

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'
)

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="[email protected]"
    )

    # 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'
