This page explains how to add Google Pay to your existing 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.

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:
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.
- Make sure that 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.
