Let buyers who use Safari pay with Apple Pay on your website, authorizing each payment with Touch ID or Face ID.
Adding Apple Pay to your website has two parts. First, you register and verify your domain with Apple through the Finix Dashboard. Then, you add the Apple Pay button and session logic to your site and process the resulting token with the Finix API.
After setup, buyers on Safari can complete checkout with Apple Pay and you process the payment like any other Finix transaction.
Finix recommends passing the address field shown in the steps below. If you do not pass the address, the card network charges additional dues and assessments per transaction.
Before you start, familiarize yourself with the Apple Pay requirements for Finix, including the Finix API key, seller onboarding, and Apple Developer account steps.
See a live demo of Apple Pay on the Finix sample store. All of the sample store code is available in the accept-a-payment GitHub project.
The Apple Pay button does not render in the Finix sample store unless you are logged in on the Apple Developer site.
In the sample store, add a few items to your cart and click Pay with Tokenization Form.

An express checkout button brings up the Apple Pay button. The sample store uses Sandbox credentials, so you are not charged.

Before you can accept Apple Pay, verify and register your domain with Apple. You complete this step in the Finix Dashboard. After you register the domain, download the verification file and host it on your website.
Register at either the Application level or the Merchant level.
To register at the Application level:
- Log in to your Finix Dashboard and click Developer.
- Click the Alt Payment Methods tab.
- Click Add Web Domain and follow the instructions to host the verification file.

Do not click Submit on step 3 in the modal until you've uploaded the verification file that Finix generates in the steps below.
- Enter a domain name.

- Download the verification file.

- Host the verification file at
/.well-known/apple-developer-merchantid-domain-association.

After you verify and register your domain with Apple, add the Apple Pay library. This script lets your site call the Apple Pay API.
<script src="https://applepay.cdn-apple.com/jsapi/1.latest/apple-pay-sdk.js"></script>After you add the Apple Pay library, add an HTML element named apple-pay-button.
Apple requires the button to be named apple-pay-button.
The button element supports the following attributes.
| Field | Type | Description |
|---|---|---|
buttonstyle | string, optional | Color of the button. Available values are black, white, and white-outline. |
type | string, required | The button type that initiates the transaction. For the full list of available button types, pass one of Buy (default), Plain, Add Money, Book, Checkout, Continue, Contribute, Donate, Order, Pay, Reload, Rent, Set Up, Subscribe, Support, Tip, or Top Up. |
locale | string, required | The language of the button. |
To preview every Apple Pay button style, see Apple Pay's interactive demo.
<style>
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;
}
</style>
<apple-pay-button
buttonstyle="black"
type="plain"
locale="en"
></apple-pay-button>After you add the Apple Pay button, create an ApplePaySession by passing a version number and an ApplePayPaymentRequest object to the constructor. To collect a billing address, include requiredBillingContactFields in the request. Then call begin() on the session to start the payment flow.
The ApplePayPaymentRequest object accepts the following fields.
| Field | Type | Description |
|---|---|---|
countryCode | string, required | The ISO country code. |
currencyCode | string, required | The currency code of the locale. |
merchantCapabilities | array, required | The payment types, such as credit or debit, that the merchant supports. The value supports3DS is required. |
supportedNetworks | array, optional | The payment networks the merchant supports. Included networks are amex, discover, jcb, masterCard, and visa. |
total | object, required | The label field is a short, localized description of the line item. The amount field is the monetary amount of the line item in the format 0.00. |
requiredBillingContactFields | array, optional | Pass postalAddress to obtain a postal address and the buyer's name after the buyer authorizes the transaction. If you do not retrieve the address to pass to Finix, additional fees apply. |
var createAndStartApplePaySession = function(description, amount) {
var applePaySession = new ApplePaySession(6, {
"countryCode": "US",
"currencyCode": "USD",
"merchantCapabilities": ["supports3DS"],
"supportedNetworks": [ "visa", "masterCard", "amex", "discover"],
"total": { "label": description, "amount": amount },
"requiredBillingContactFields": ["postalAddress"]
});
applePaySession.begin();
}A Buyer Identity is required before you can process a payment. You can create a new Buyer Identity with the Finix API, or use an existing one.
All Buyer Identity fields are optional. Finix recommends including basic information (name, email, address, and phone) to make payment operations easier.
To find and reuse an existing Buyer Identity:
- Log in to your Finix Dashboard.
- In the left sidebar, select Data Resources → Identities.
- Search for the Buyer Identity you want to use, and confirm its Role is Buyer.
- Copy the Buyer Identity ID (for example,
IDjWktr7BPDGhz4amrPJZoXg).
After you start an Apple Pay session, validate and complete an Apple Pay merchant session with POST /apple_pay_sessions. Your server securely exchanges certificates with Apple's servers and Finix to complete the setup.
To validate the session, set up the onvalidatemerchant function to capture the validation URL and send it, along with the merchant details, to your backend. Your server processes the request with Finix and returns Apple's validation response. Then, call completeMerchantValidation() with the response to authorize the session.
var validateMerchantSession = function(applePaySession) {
applePaySession.onvalidatemerchant = function(event) {
try {
var validationURL = event.validationURL
console.log("Validating merchant with url: " + validationURL );
if (validationURL) {
var request = {
provider: "APPLE_PAY",
validation_url: validationURL,
merchant_identity: merchantIdentity,
domain: "www.finixtestmerchant.com",
display_name: "Finix Test Merchant"
}
// call your server, which then calls Finix's /apple_pay_sessions
fetch(serverUrl, {
method: "POST",
headers,
body: JSON.stringify(request)
}).then((response) => response.json())
.then((data) => {
// the session details return as a string; parse them into an object
var merchantSession = JSON.parse(data['session_details']);
applePaySession.completeMerchantValidation(merchantSession);
})
} else {
console.log("Merchant validation failed");
}
}
catch(err) {
console.log(err);
throw err;
}
}
}Next, pass the validation_url into a POST request to apple_pay_sessions. Finix returns a merchantSession object that you use in the next step.
The request accepts the following arguments.
| Field | Type | Description |
|---|---|---|
display_name | string, required | The merchant name shown to buyers when they pay with Apple Pay and Touch ID. |
domain | string, required | The domain where the buyer initiates the payment. |
merchant_identity | string, required | The merchant identity ID used when registering the business with Apple Pay through the registration API. To find it, log in to your Finix Dashboard and go to Developer → Finix Integration → Merchant Identity ID (for example, IDmULj61C8ke6Y7qQiKENJ7). |
validation_url | string, required | A validation URL that the Apple SDK front end provides for every payment. |

}
}After the merchant session validates, Apple Pay prompts the buyer to authenticate with Touch ID, Face ID, or a device passcode.
When the buyer authorizes the payment, the onpaymentauthorized function provides an encrypted token. Your site sends this token to your backend for processing with Finix. Your backend returns the result, which you use to call completePayment() and finalize the Apple Pay session.
var processPayment = function (applePaySession) {
applePaySession.onpaymentauthorized = function (event) {
try {
//token received from Apple
var paymentToken = event.payment;
if (paymentToken) {
console.log("Payment token from Apple: " + paymentToken);
// extract billing details
var addressData = {
country: paymentToken.billingContact.countryCode,
postal_code: paymentToken.billingContact.postalCode,
};
var name = paymentToken.billingContact.givenName + " " + paymentToken.billingContact.familyName;
// send Finix API stringified form of the isolated token
var third_party_token = {
token: paymentToken.token,
};
var stringifiedPaymentToken = JSON.stringify(third_party_token);
// call the server to handle the orchestration of Finix calls
processPaymentFromServer(stringifiedPaymentToken, addressData, name);
applePaySession.completePayment(applePaySession.STATUS_SUCCESS);
console.log(
"Finix processed transaction successfully with token: " +
paymentToken,
);
} else {
console.log(
"Payment token from Apple is null - payment failed to process.",
);
applePaySession.completePayment(applePaySession.STATUS_FAILURE);
}
} catch (err) {
console.log(err);
throw err;
}
};
};Then, your server passes the payment token as third_party_token, the address data as address, and the value for name when creating a Payment Instrument.

}Alternatively, create an Authorization and capture it later with two separate API calls. This is useful when you need to verify the payment details first and capture a specific amount later. For more information, see Creating and capturing an Authorization.
