Integration
Initial Setup
Step 1: Add the Apple Pay Script
Include the following script tag in the <head>
section of your HTML page:
<script src='https://test-pay.dnapayments.com/components/apple-pay/apple-pay-component.js'></script>
Step 2: Create a DOM Element
Create a container where the Apple Pay button will be rendered:
<div id='apple-pay-btn-container'></div>
Event Handlers for Apple Pay
Step 3: Handling the onClick Event
The onClick
event is triggered when the Apple Pay button is clicked. You can use this handler to manage the click event:
function onClick() {
console.log('Apple Pay button has been clicked');
}
Step 4: Handling Errors with onError
The onError
event handles errors that occur during the Apple Pay process. It is essential to handle these errors gracefully to ensure a good user experience:
function onError(error) {
console.log('Error occurred:', error);
// Implement additional error handling logic
}
Step 5: Handling the onCancel Event
The onCancel
event is triggered when a user cancels the Apple Pay transaction. Implement this callback to reset the checkout process or notify the user:
function onCancel(event) {
console.log('Payment was cancelled:', event);
// Reset the checkout state
}
Step 6: Handling the onPaymentSuccess Event
The onPaymentSuccess
event is triggered when a payment is successfully processed. Use this handler to finalize the transaction and retrieve customer details:
function onPaymentSuccess(result) {
console.log('Payment has successfully been processed', result);
// Implement further actions such as redirecting to a success page or storing the payment details
}
Step 7: Creating a Combined Events Object
You can create an events object that consolidates all event handlers for easier management:
const events = {
onClick,
onError,
onPaymentSuccess,
onCancel
};
Button Initialization
Step 8: Configure paymentData
Before initializing the Apple Pay button, you need to configure the paymentData
object, which contains the details of the payment transaction, such as the currency, amount, and customer details.
const paymentData = {
currency: 'GBP', // The currency of the transaction
description: 'Shoes', // A brief description of the items or services being purchased
paymentSettings: {
terminalId: 'YOUR_TERMINAL_ID', // Your terminal ID
returnUrl: 'https://example.com/success.html', // URL to redirect upon successful payment
failureReturnUrl: 'https://example.com/failure.html', // URL to redirect upon payment failure
callbackUrl: 'https://example.com/callback', // URL for server-to-server callbacks
failureCallbackUrl: 'https://example.com/failure-callback' // URL for handling callback failures
},
customerDetails: {
accountDetails: {
accountId: 'uuid000001' // Unique identifier for the customer account
},
billingAddress: {
firstName: 'John',
lastName: 'Doe',
addressLine1: 'Fulham Rd',
postalCode: 'SW6 1HS',
city: 'London',
country: 'GB'
},
deliveryDetails: {
deliveryAddress: {
firstName: 'John',
lastName: 'Doe',
addressLine1: 'Fulham Rd',
addressLine2: 'Fulham',
postalCode: 'SW6 1HS',
city: 'London',
phone: '0475662834',
country: 'GB'
}
},
email: 'example@email.com',
mobilePhone: '+441234567890'
},
orderLines: [
{
name: 'Running shoe', // Item name
quantity: 1, // Quantity of the item
unitPrice: 24, // Price per unit
taxRate: 20, // Tax rate applied
totalAmount: 24, // Total amount for this item
totalTaxAmount: 4, // Total tax amount for this item
imageUrl: 'https://www.example.com/logo.png', // URL of the item's image
productUrl: 'https://www.example.com/AD6654412.html' // URL to the product page
}
],
deliveryType: 'service', // Type of delivery (e.g., service, physical)
invoiceId: 'YOUR_INVOICE_ID', // Unique identifier for the transaction invoice
amount: 24 // Total transaction amount
};
Step 12: Initialize the Button
To initialize the Apple Pay button and configure it for processing transactions, use the following method:
window.DNAPayments.ApplePayComponent.create(
document.getElementById('apple-pay-btn-container'), // The container element where the button will be rendered
paymentData, // Your configured payment data
events, // The events object containing all your event handlers
'YOUR_ACCESS_TOKEN', // Your access token
);
The access token returned from the API is an object that includes several fields such as access_token
, expires_in
, token_type
, and others. Only the access_token
field should be passed during button initialization. For more details on how to obtain the access token, follow the instructions outlined here.
When obtaining the access token, make sure to pass the following scopes to ensure proper initialization of the button: payment integration_seamless
