Integrating secure payment infrastructure for web applications

Core Idea: Stripe is a payment processing platform that enables businesses to accept online payments through a secure API, handling the complexities of payment verification, security compliance, and funds transfer.

Key Elements

• Key features

  • Secure payment processing
  • Multiple payment methods support
  • Subscription billing
  • Global currency handling
  • Fraud prevention tools
  • PCI compliance management

• Integration approaches

  • Direct API integration
  • Pre-built components (Elements, Checkout)
  • Mobile SDKs
  • Server-side libraries
  • No-code payment links

• Implementation steps

  1. Create Stripe account and obtain API keys
  2. Set up development environment with test keys
  3. Implement client-side payment collection
  4. Create server-side payment processing endpoints
  5. Configure webhooks for event handling
  6. Test payment flow in test mode
  7. Switch to live mode for production

• Code example (Next.js Stripe integration)

// Server-side API endpoint
// pages/api/create-payment-intent.js

import Stripe from 'stripe';

const stripe = new Stripe(process.env.STRIPE_SECRET_KEY);

export default async function handler(req, res) {
  if (req.method !== 'POST') {
    return res.status(405).json({ error: 'Method not allowed' });
  }

  try {
    const { amount, currency, description } = req.body;
    
    // Create a PaymentIntent with the order amount and currency
    const paymentIntent = await stripe.paymentIntents.create({
      amount: amount,
      currency: currency || 'usd',
      description: description,
      automatic_payment_methods: {
        enabled: true,
      },
    });

    res.status(200).json({
      clientSecret: paymentIntent.client_secret,
    });
  } catch (error) {
    console.error('Error creating payment intent:', error);
    res.status(500).json({ error: error.message });
  }
}

• Payment methods supported
  • Credit and debit cards
  • Digital wallets (Apple Pay, Google Pay)
  • Bank transfers (ACH, SEPA)
  • Buy Now Pay Later (Klarna, Afterpay)
  • Local payment methods (Alipay, iDEAL, etc.)

Additional Connections

• Broader Context: Payment Gateway Architecture (Stripe as a payment gateway implementation)
• Applications: Subscription Business Models (recurring payment implementation)
• See Also: PCI DSS Compliance (security standards for handling payments)
