Online payments

You can accept payments through Apple Pay via Checkout (Hosted Payments Page - HPP) or via eComm API.

Follow the integration steps below to process transactions via Verifone ecomm API.

Merchant onboarding

1. Merchant shall register a merchant ID through Apple (see instructions here: https://developer.apple.com/library/archive/ApplePay_Guide/Configuration.html#//apple_ref/doc/uid/TP40014764-CH2) 
2. Merchant needs to request through Verifone the generation of the cryptographic keys. Verifone generates cryptographic keys and provide the public key via a Certificate Signing Request (CSR) to the merchant.
3. Merchant shall upload the CSR to the Apple Developer portal in return, Apple will provide the merchant a certificate.
    (see instructions here: https://developer.apple.com/library/archive/ApplePay_Guide/Configuration.html#//apple_ref/doc/uid/TP40014764-CH2) 
4. Merchant shall import the certificate that received in step #3 in Verifone.
5. Merchant will need to download and host the domain-verification file at the following path: https://[DOMAIN_NAME]/.well-known/apple-developer-merchantid-domain-association

Generate a unique merchant_reference

The merchant_reference needs to be unique to identify the shopper when they are redirected to your server by Apple Pay. In the next step, you will be creating a transaction through the API, the transaction will return an id that needs to be stored safely with the reference. When the shopper returns, you can use this reference to confirm either through the webhook or through the GET transaction API call if the shopper has successfully completed the transaction.

Web Integration

An Apple Pay web integration consists of implementing both client side and server side components. You will need to implement the following:

• Create your apple pay button and initialize your apple pay session when clicked.
  https://developer.apple.com/documentation/apple_pay_on_the_web/displaying_apple_pay_buttons_using_javascript
• Initiate the merchant session by calling the on the validatemerchant event and provide the response to the session.completeMerchantValidation callback.
  https://verifone.cloud/api-catalog/verifone-ecommerce-api#operation/validationUrl
• Use the Apple Pay token to make a wallet transaction API call and complete the apple pay session based on the response.

Code sample

const ApplePaymentOptions = {
  countryCode: "US",
  currencyCode: "USD",
  merchantCapabilities: ["supports3DS"],
  supportedNetworks: ["visa", "masterCard", "amex", "discover"],
  total: {
    label: "Demo (Card is not charged)",
    type: "final",
    amount: "1.99",
  },
};

const canMakePayments =
  window.ApplePaySession && window.ApplePaySession.canMakePayments();

let session;
function handleApplePayRequest(formValues) {
  if (canMakePayments) {
    session = new window.ApplePaySession(3, ApplePaymentOptions);
    session.onpaymentauthorized = makeTransaction(formValues);
    session.addEventListener("validatemerchant", validateMerchant);
    session.begin();
    console.log("INFO - BEGIN SESSION...");
  }
}

function validateMerchant(e) {
  // Pass the validation URL and domain to your server to make the wallet transaction API call
  fetch(`YOUR_ENDPOINT`, {
    method: "POST",
    headers: REQUEST_HEADERS,
    body: JSON.stringify({
      validation_url: e.validationURL,
      domain: window.location.hostname
    }),
  })
    .then((res) => res.json())
    .then((sessionObject) => {
      session.completeMerchantValidation(sessionObject);
    })
    .catch((err) => console.log("ERROR - MERCHANT VALIDATION: ", err));
}

function makeTransaction(formValues) {
  return (e) => {
    const applePaymentObject = e.payment;
    const payload = {
      token: applePaymentObject.token.paymentData,
    };

    // Pass the apple pay token to your server to make the wallet transaction API call
    fetch(`YOUR_ENDPOINT`, {
      method: "POST",
      headers: REQUEST_HEADERS,
      body: JSON.stringify(payload),
    })
      .then((res) => res.json())
      .then((res) => {
        // Check the response status and complete the payment session
        if (res.status === 'AUTHORIZED') {
          session.completePayment(0);
        }
      })
      .catch((err) => console.log("ERROR: ", err));
  };
