Google Pay Drop-in integration

On this page, you can find additional configuration for adding Google Pay to your Drop-in integration.

When shoppers select Google Pay, Drop-in presents the Google Pay payment sheet where shoppers choose a card they want to use. If shoppers select a card that requires 3D Secure authentication, Drop-in also handles redirecting shoppers to another website to complete the verification.

Before you begin

Before starting your Google Pay integration:

1. Build a Drop-in integration.
2. Add Google Pay in your Customer Area.
3. Follow the setup steps in the Google Pay documentation.

API reference

You don't need to send additional fields for Google Pay. To see optional fields that you can send for all payment methods, choose the endpoint you integrated:

• /sessions: This is the default with Drop-in v5.0.0 or later.
• /payments: If you implemented an additional use case.

Drop-in configuration

Load the Google Pay API JavaScript library

We recommend that you preload the the Google Pay API JavaScript library, by including the
following script in your checkout page:

<script src="https://pay.google.com/gp/p/js/pay.js"></script>

Required configuration

Select which endpoint you're integrating:

/sessions /payments

/sessions /payments

This is the default with Drop-in v5.0.0 or later.
There's no additional configuration you need to include for Google Pay.

If you implemented an additional use case.

Parameter name	Required	Description
amount.value		The value of the payment, in minor units.
amount.currency		The currency code of the payment.
countryCode		The two-letter country code of your merchant account.

The following example shows how to configure Drop-in:

Google Pay configuration

const googlePayConfiguration = {
    amount: {
        value: 1000,
        currency: "EUR"
    },
    countryCode: "NL",
    //Set this to PRODUCTION when you're ready to accept live payments
    environment: "TEST"
};

Include the googlePayConfiguration object when creating a configuration object:

AdyenCheckout configuration

const configuration = {
  // ...  other required configuration
  paymentMethodsConfiguration: {
    googlepay: googlePayConfiguration
  }
};

Optional configuration

This optional configuration parameter is only accepted on the dropin instance.

Instant payment button configuration

Use the instantPaymentTypes object to display the Google Pay payment button at the top of the list of available payment methods. The sample below shows how to do this:

const dropin = checkout.create('dropin', {
    // ... other optional configuration
    // For v5.30.0 or later: you can also use the value googlepay.
    instantPaymentTypes: ['paywithgoogle']
}).mount('#dropin-container');

Optional Google Pay configuration

You can configure:

• The merchant name that appears on the Google Pay payment sheet.
• The Google Pay button appearance.
• Your payment requirements.
• The card types that you accept.
• The payment methods that you support.
• Event handlers to use.

Merchant info

Configure the merchant name rendered in the payment sheet. See MerchantInfo for more details.

Button options

Configure the Google Pay button. See ButtonOptions for more details.

Payment data

Configure your payment requirements. See PaymentDataRequest for more details.

Card parameters

Configure accepted card types. See Card Parameters for more details.

Payment method support

Specify which payment methods are supported. See IsReadyToPayRequest for more details.

Events

The following event handlers are supported for Google Pay.

Recurring payments

To make recurring Google Pay payments, you first need to create a shopper token and then make subsequent recurring transactions with the token.

Refer to Tokenization for more information and detailed instructions.

Test and go live

To test Google Pay, log in to a Google account and create a Google Pay wallet with the details of a real card, not a test card. When you make a test payment, the card number is automatically mapped to our test card number starting with 4111, so the real card is not charged.

You can check the status of a Google Pay test payment in your Customer Area > Transactions > Payments.

For more information, see Google Pay's test environment setup for Web.

Before you go live

1. Make sure your API credential has the API Clientside Encryption Payments role. Check this in your live Customer Area or ask your Admin user to verify.
2. Go to your live Customer Area to configure your Google Merchant ID.
3. Complete the steps in the Google Pay API deploy to production documentation for Web.

In the live environment, note that Google Pay will only be available if:

• The shopper is logged in to their Google account.
• The shopper has at least one valid payment method on their Google Pay account.
