Google Pay Drop-in integration

Add Google Pay to an existing 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:

  • Build a Drop-in integration.
  • Follow the setup steps in the Google Pay documentation.
  • Add Google Pay in your Customer Area.
  • API reference

    You don't need to send additional fields for Google Pay. See the /payments endpoint API reference for the optional fields you can send.

    Drop-in configuration

    There is no required Google Pay specific integration for Drop-in.

    Optional configuration

    You can optionally include the following properties when you configure AdyenCheckout:

    Property Description Default

    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 start testing Google Pay, log in to a Google account and create a Google Pay wallet.

    There are two approaches to using this wallet for testing:

    Enroll your wallet in Google's test card suite. Test card suite pre-populates your wallet with a group of cards to use in the TEST environment. These are related to Adyen's collection of test cards, and cover scenarios including:

    • Cards stored as FPAN
    • Cards stored as DPAN (only when testing through native Android and Chrome on Android)
    • Cards enabled for 3DS2

    When you start the payment flow and open the list of test cards, each card is marked with the applicable scenario.

    You can check the status of a Google Pay test payment in your Customer Area > Transactions > Payments, whether you used a card from the test card suite or or not. Remember that cards outside the test card suite are mapped to an Adyen test card of the same brand.

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

    Before you go live

    We recommend that you test the scenarios described in Google Pay’s API reference for Android in your live environment.

    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 all the steps in the Google Pay API deploy to production documentation for Android.

    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.
