Apple Pay on the Web
Interactive Demo

Try an Apple Pay test transaction using the button below.
Transactions made on this site do not charge your card.


Use this page to learn how to enable Apple Pay on the web using Apple Pay JS or the Payment Request API. This demo preconfigures the Apple Pay button below with default values. Explore further by modifying values in the code blocks throughout the page to customize payment sheet experiences. This demo displays a transcript of server responses after each transaction for context. Click or tap the the "Show Transcript" tab to view the transaction transcript.

As well as letting you try out the Apple Pay JavaScript APIs, this demo can also serve as a tutorial for your own implementation. It assumes you have already set up your environment to process Apple Pay transactions, and are familiar with Apple Pay best practices. Before starting your integration, we recommend reviewing Getting Started with Apple Pay and the Apple Pay on the Web Human Interface Guidelines. For more information about supporting Apple Pay on your website, see Apple Pay on the Web.

This demo uses Apple Pay JS version 3, and to run this demo you must be using:

  • iOS devices running iOS 11 or later
  • Safari 11 on macOS 10.13 or later

Display an Apple Pay button

To display an Apple Pay Button, use the following code to load the button script into your webpage from the content delivery network:

<script src=""></script>

The JavaScript Apple Pay button provides a variety of Apple Pay button types that you can use on your website to initiate a transaction. You can specify the Apple Pay button style, type, and localization using attributes. Use CSS to set other properties, such as the size and corner radius. Using the official Apple Pay button element ensures your site will display the latest style, render correctly across devices, and follow Apple Guidelines. For design guidance, see Human Interface Guidelines > Apple Pay > Buttons and Marks.

Try it: Display Settings

Use the following tools to try the different display settings on the button shown below:

apple-pay-button {
  --apple-pay-button-width: 150px;
  --apple-pay-button-height: 30px;
  --apple-pay-button-border-radius: 3px;
  --apple-pay-button-padding: 0px 0px;
  --apple-pay-button-box-sizing: border-box;
<apple-pay-button buttonstyle="black" type="plain" locale="en"></apple-pay-button>

Create a Payment Request

When your customer clicks or taps the Apple Pay button, you must first construct an ApplePaySession object which includes the ApplePayPaymentRequest dictionary detailing the transaction details the payment sheet will display.

The ApplePayPaymentRequest requires details including: the total payment for the transaction, the currency, and the supported payment networks. You can optionally pass lineItems to show additional charges and discounts, and shippingMethods to allow the customer to choose from different shipping options. If you require address or contact details from your customer, request them by passing values in the requiredShippingContactFields or requiredBillingContactFields.

You can set up recurring payments, such as subscriptions, that feature different payment intervals (for example, annual or monthly) and billing cycles (for example, regular or trial) by passing recurringPaymentRequest to the ApplePayPaymentRequest and with the ApplePayLineItem that has recurring paymentTiming.

You can set up deferred payments, where a user pays at a later date with the ApplePayLineItem that has recurring paymentTiming and a valid date in the deferredPaymentDate property.

You can set up automatic reload payments, such as store card top-ups, by passing automaticReloadPaymentRequest to the ApplePayPaymentRequest and with the ApplePayLineItem that has automaticReload paymentTiming, the amount to describe reload amount, and the automaticReloadPaymentThresholdAmount to describe the threshold amount balance that is reached before automatically applying the reload amount.

You can set up multi-token transactions to process and display payments with multiple merchants on one payment sheet, for example, a booking site where a user pays for a hotel, flight, and car rental from different merchants. You can do this by passing ApplePayPaymentTokenContext in the multiTokenContexts property to the ApplePayPaymentRequest.

Try it: ApplePayPaymentRequest

Modify the values in the ApplePayPaymentRequest shown below and click or tap the Apple Pay button to view the payment sheet. Choose Basic Request to see a payment sheet with only the required fields. Choose Detailed Request to show code including optional fields, such as lineItems. Choose Recurring Payment Request to demo a recurring payment, using the ApplePayRecurringPaymentRequest and the relevant fields in ApplePayLineItem like recurringPaymentStartDate. Choose Deferred Payment Request to demo a deferred payment, using the relevant fields in ApplePayLineItem like deferredPaymentDate. Choose Automatic Reload Payment Request to demo automatic reload payments, using the relevant fields in ApplePayLineItem like automaticReloadPaymentThresholdAmount. Choose Multi-Merchant Payment Request to show how to create a request for multiple payment tokens on a transaction by passing one ApplePayPaymentTokenContext for each token in the multiTokenContexts property.

Complete Merchant Validation

Before being able to display the payment sheet to the customer, you must generate a valid payment session by interacting with Apple Pay Servers. For security reasons, your server must do this, not your browser client code, unlike everything else in this demo. To start the merchant validation process, call the begin method on the session object you created above.

Once you do, the browser will invoke your onvalidatemerchant handler, which must fetch a merchant session from your server.

Refer to the instructions in Requesting an Apple Pay Payment Session document to implement your server endpoint responsible for fetching the merchant session object from Apple Pay servers. If successful, Apple Pay servers will return a merchant session object, which your server must then pass back as the response to the browser.

Once you have the merchant session response object in the browser, you must complete your onvalidatemerchant handler by passing that object to the completeMerchantValidation method on the session object. The browser will then display the payment sheet.

The following code shows an example of how to validate merchant:

session.onvalidatemerchant = event => {
    // Call your own server to request a new merchant session.
      .then(res => res.json()) // Parse response as JSON.
      .then(merchantSession => {
      .catch(err => {
        console.error("Error fetching merchant session", err);

Respond to Payment Sheet Interactions

After merchant validation is complete, Apple Pay provides the information about your customer’s payment sheet selections so that you can calculate the final transaction cost. The final details of a transaction may depend on user payment method, billing address, shipping address, or shipping method. To handle these adjustments, implement the optional handlers onpaymentmethodselected, onshippingmethodselected, and onshippingcontactselected. When the browser calls one of these handlers, you have 30 seconds to process it and call the corresponding callback function, otherwise the transaction times out. All callbacks accept an object with newTotal (required), newLineItems (optional), newMultiTokenContexts (optional), newRecurringPaymentRequest (optional) and newAutomaticReloadPaymentRequest (optional) keys. In addition, you may specify newShippingMethods to update shipping methods, and errors to indicate problems with the user's selected shipping address when calling completeShippingContactSelection.

errors (optional)

Demo Note: The test transaction always passes in a default success response when it calls completePaymentMethodSelection. The test transaction passes in newLineItems and newTotal when it calls completeShippingMethodSelection. See responses in the transcript.

Request a Shipping Address

If you pass requiredShippingContactFields in the payment request with a postalAddress value, Apple Pay provides redacted address information before the user authenticates the transaction. After the user authenticates, Apple Pay provides the full contact information.

The redacted payment information includes only the data needed to complete required transaction tasks, such as calculating taxes or shipping costs, and may differ based on the user's geographic region.

The following code shows an example of a redacted payment information:

    "administrativeArea": "CA",
    "country": "United States",
    "countryCode": "US",
    "familyName": "",
    "givenName": "",
    "locality": "San Francisco",
    "phoneticFamilyName": "",
    "phoneticGivenName": "",
    "postalCode": "94114",
    "subAdministrativeArea": "",
    "subLocality": ""

Try it: completeShippingContactSelection

Choose 'Success' with or without updating line items and total below. Choose 'Failure' to see completeShippingContactSelection response with custom errors. You may edit the ApplePayShippingContactUpdate response object below to experiment with different responses. Click or tap the Apple Pay button below to see how the payment sheet displays updates or address errors.

Authorize the Payment

Finally, you must implement the onpaymentauthorized handler, that will be responsible for processing the transaction. After the user authenticates the transaction using Face ID, Touch ID, or their device passcode, this handler gets called with the encrypted Apple Pay token, as well as the shipping and billing fields if you requested them in the ApplePayPaymentRequest. To finalize the transaction, you need to pass the encrypted payment token to your payment processor using their API.

Once you receive the response from your payment processor, call the completePayment method on the session and indicate either STATUS_SUCCESS, or STATUS_FAILURE with an array of associated ApplePayError objects.

You may also validate the shipping and billing info, and invoke the completePayment method immediately, without calling the payment processor, if you detect an problem with the selected options (for example, if a user has selected a shipping address in a location that you do not service). Use the contactField key to specify the exact field that is causing the error.

Try it: completePayment

Use the following values to customize the completePayment response below:

Choose Success below to default to STATUS_SUCCESS. Choose Failure to see a completePayment response with custom errors.

Click or tap the Apple Pay button below to see how the payment sheet completes the payment.
