Apple Pay integration

Apple Pay™ is a payment option for the customer. Apple securely stores the customer's card information and hands it over to the merchant for processing.

NOTE
We currently only support Apple Pay for the web, native iPhone app support is coming soon.

Implementation modes

Apple Pay can be emebedded two ways into your payment flow. In the first case, it will be displayed on Barion Smart Gateway ("Hosted Gateway"), which needs no further configuration and/or development on your side. The second option is to display the Apple Pay button on your site ("integrated mode"), however this needs configuration and development on your side. This page will discuss the latter.

Prerequisits

IMPORTANT
To integrate this feature you have to develop the integration yourself! You need to understand Javascript code and it is also required to modify your webshop's server code!
  • you must have a Barion wallet
  • the beforementioned Barion wallet must have and approved shop
  • for every currency you plan to conduct payments in you have to make sure there is an account created in your Barion wallet. This means that if you plan to have USD payments then there should be an USD account created in your wallet.
  • all the example codes assume the availability of jQuery

Limitations

Technical

Shop

  3. The JS code receives a session data
  4. The JS code sends this information to the server side of the merchant
  5. The server side gathers the information necessary to call the /v2/ApplePay/ValidateSession endpoint.
  6. Apple Pay screen is displayed, where the customer can select the card, shipping address and contact details.

Configuration

Domain verification file

First head over to secure.barion.com, and under Manage My Shops page select the appropriate one, and from the dropdown, click on settings. At the bottom click the Manage Apple Pay settings blue button under the Apple Pay Settings section. On the next page Click on the Download domain verification file button, which will download a domain association file. You should place this file at the content root of all of your sites, you're about to use apple pay in integrated mode. The file must:

  • have Content-Type: text/plain in the header.
  • be externally accessible.
  • not be password protected.
  • the file cannot be behind a proxy or redirect.
  • your site must use https.

Configure Domains

On the exact same page you've downloaded the domain association file, enter all the domains (one in each line, without https:// or https://) you're intending to use Apple Pay.

Development

Include the Apple Pay SDK

Include the following code snippet in the header of your checkout page: <script src="https://applepay.cdn-apple.com/jsapi/v1/apple-pay-sdk.js"></script>

Display the Apple Pay button

Add the Apple Pay button to your checkout page as discussed here

Create an Apple Pay session

When the user taps the Apple Pay button, provide a payment request and create the session as discussed here

Subscribe to the onvalidatemerchant event

Call your backend, which will in turn call the Barion Api ValidateSession endpoint in the event handler with the provided url as the payload:

	 appleSession.onvalidatemerchant = function (event) {
		// TODO: disable Apple Pay button
		const data = {
			SessionValidationUrl: event.validationURL
		};

		$.ajax({
			method: "POST",
			url: "https://yourserver.com/ValidateApplePaySession",
			data: data,
			success: function (response, status, xhr) {
				const merchantSession = JSON.parse(response.ApplePaySessionResponse);
				appleSession.completeMerchantValidation(merchantSession);
			},
			error: function (xhr, status, error) {
				// failure callback
				// TODO: enable Apple Pay button
			}
		});
	};

Subscribe to the onpaymentauthorized event

Call your backend, which will in turn call the Barion Api StartPaymentWithAppleToken endpoint in the event handler with the provided payment payload:

	appleSession.onpaymentauthorized = function (event) {
		let cart = {
			Payload = event.payment
			PaymentType = "Immediate",
			Mode = "",
		};

		$.ajax({
			method: "POST",
			url: "https://yourserver.com/StartApplePayment",
			data: cart,
			success: function (response, status, xhr) {
				if (response.IsSuccessful && response.PaymentStatus === 40) {
					appleSession.completePayment(appleSession.STATUS_SUCCESS);
				} else {
					appleSession.completePayment(appleSession.STATUS_FAILURE);
				}
			},
			error: function (xhr, status, error) {
				appleSession.completePayment(appleSession.STATUS_FAILURE);
			}
		});
	};

Call ApplePaySession.begin method

Call the begin method, and the merchant validation process begins. So your final client side code will look like this:

var request = {
  countryCode: 'HU',
  currencyCode: 'HUF',
  supportedNetworks: ['visa', 'masterCard', 'amex', 'discover'],
  merchantCapabilities: ['supports3DS'],
  total: { label: 'Your Merchant Name', amount: '1000.00' },
};
var appleSession = new ApplePaySession(3, request);
appleSession.onvalidatemerchant = function (event) {...}
appleSession.onpaymentauthorized = function (event) {...}
appleSession.begin();
