const result = await Eitri.exposedApis.applePay.pay({
  countryCode: "US",
  currencyCode: "USD",
  shippingMethods: [
     { identifier: "standard", label: "Standard Shipping", amount: 150, detail: "5-7 business days" }
  ], 
  summaryItems: [
    { label: "Subtotal", amount: 300 },
    { label: "Shipping", amount: 150 },
    { label: "Total", amount: 450, type: "final" }
  ],
})
Output:
{
  paymentData: "<REDACTED>",
  paymentMethod: { 
    type: "credit",
    network: "MasterCard",
    displayName: "MasterCard 1111"
  },
  transactionIdentifier: "<REDACTED>"
