Visa Checkout is a third-party service that stores payment and shipping information for its users to streamline the checkout process. Instead of entering payment information on your checkout page, users can click the Visa Checkout button instead. Your Stripe integration receives a unique ID that it can use to create a charge against the payment information stored in the user’s Visa Checkout account.

Integrating the Visa Checkout button

To get started, generate your Visa Checkout API key in the Dashboard. There are two keys, a sandbox key that you can use while testing, and a production key that works in live mode.

<script type="text/javascript" src="https://sandbox-assets.secure.checkout.visa.com/checkout-widget/resources/js/integration/v1/sdk.js"></script>

<img alt="Visa Checkout" class="v-button" role="button" src="https://sandbox.secure.checkout.visa.com/wallet-services-web/xo/button.png">

To initialize the button, add an onVisaCheckoutReady function that invokes V.init:

function onVisaCheckoutReady() {
  V.init({
    apikey: '{{VISA_CHECKOUT_ID}}',
    paymentRequest:{
      subtotal: '10.00',
      currencyCode: 'USD'
    },
    settings: {
      displayName: 'My Website'
    }
  });
}

The Visa Checkout JavaScript SDK automatically invokes the onVisaCheckoutReady function when it finishes loading. The paymentRequest property accepted by V.init requires the following parameters:

By default, American Express, MasterCard, Visa, and Discover card brands are accepted, all shipping and billing countries are also enabled.

For more details about the V.init function and the parameters that it accepts, refer to Visa’s documentation. There are optional paymentRequest properties that support a range of other features, including promotions, discounts, and taxes. There are also optional settings properties that allow you to control the shipping information options.

Completing the payment

When the user clicks the Visa Checkout button on your checkout page, it opens a lightbox where they can select an existing payment method from their account or input a new one. When the user completes the process, the Visa Checkout JavaScript SDK in the browser emits a payment.success event with a unique ID that your application can use to complete the transaction.

The following code shows how to handle the payment.success event and confirm the PaymentIntent you created at the beginning of the checkout flow. See accept a payment to learn how to manage your checkout flow using Payment Intents.

// PaymentIntent client secret passed from server-side.
// See: https://stripe.com/docs/payments/accept-a-payment?platform=web
// for more information on how to do this.
const clientSecret = '{{CLIENT_SECRET}}';

V.on('payment.success', async (payment) => {
  const intent = await stripe.confirmCardPayment(clientSecret, {
    payment_method: {
      card: {
        visa_checkout: {
          callid: payment.callid,
        },
      },
    },
  });
  // Perform logic for payment completion here
});

Testing Visa Checkout

To test your integration against Visa Checkout’s sandbox, create a new Visa Checkout user account during the checkout process on your website. Configure the account to use the test card number 4242 4242 4242 4242, a random three-digit CVC number, and any expiration date in the future. Complete the checkout process as normal. If everything works correctly, Visa Checkout redirects you back to your application, which creates the charge as expected.
