🍎 Apple Pay : Guide d’Intégration

Fonctionnement Technique

// Apple Pay integration example
const applePaySetup = {
  requirements: {
    certificate: 'Apple Pay merchant certificate',
    ssl: 'TLS 1.2+ mandatory',
    domain: 'Registered Apple Pay merchant domain',
    server: 'Stripe/Adyen handles complexity'
  },

  // Easy path: Use payment processor
  recommended_approach: {

      'Apple Pay certificate',
      'Tokenization',
      'Fraud detection',
      'Compliance'
    ],
    effort: 'Integration: 4-8 hours'
  },

  // Code example (simplified)
  implementation: `
    // Stripe + Apple Pay integration
    const paymentRequest = new PaymentRequest(
      [{ supportedMethods: ['apple-pay'] }],
      {
        total: { label: 'Total', amount: { currency: 'EUR', value: '99.99' } }
      }
    );

    paymentRequest.show().then(result => {
      // Send tokenized payment to server
      fetch('/pay', {
        method: 'POST',
        body: JSON.stringify({
          payment_token: result.details.paymentToken
        })
      });
    });
  `,

  fees: '1.5-2.9% + fixed fee per transaction',

Duration: 5-10 seconds total (vs 45+ seconds card form)

Impact on conversions:
- Mobile conversion: +25-30% vs card form
- Cart abandonment: -15-20%
- NPS impact: +10-15 points for payment experience
