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:
You don't need to send additional fields for Google Pay. See the /payments endpoint API reference for the optional fields you can send.
There is no required Google Pay specific integration for Drop-in.
You can optionally include the following properties when you configure
||Your Google Merchant ID. This can be anything for testing. Before you go live, get your Google Merchant ID from the Google Pay & Wallet Console.||The corresponding merchant ID value from the

||The status of the total price. Possible values:

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, create a Google Pay wallet and add the details for a real card.
When you test with this card it will be masked to one of our test cards, so there are no charges to your card. Your test transactions show test card details of the same brand in your Customer Area.
You can enrol your wallet in the Google Pay test card suite to use their test cards, which cover a limited number of scenarios. For example, you cannot test changes to your configuration in the
PaymentDataRequest object using the Google Pay test card suite because Google Pay API always returns the same output.
Currently, Google Pay wallets enrolled in the Test Card Suite return only full PAN tokens (FPANs) for test payments, and not device authenticated tokens AKA Cryptograms.
To test 3D Secure 2, you can use American Express or Discover cards, which trigger 3D Secure 2 challenge flows in the test environment. You cannot use any other card brands or any of Google Pay's test cards to test 3D Secure 2.
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 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.
- 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.
- Go to your live Customer Area to configure your Google Merchant ID.
- 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.
