There are two approaches to using this wallet for testing: * **Enroll in test card suite** Enroll your wallet in Google's [test card suite](https://developers.google.com/pay/api/android/guides/resources/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. * **Without test card suite** You upload real credit cards to your wallet, which are mapped to one of Adyen's [test cards](/development-resources/test-cards-and-credentials/test-card-numbers) of the same brand. Your card is not charged. To test 3D Secure 2, you must use American Express or Discover cards, which trigger 3D Secure 2 challenge flows in the test environment. You cannot use any other card brands. You can check the status of a Google Pay test payment in your [Customer Area](https://ca-test.adyen.com/) > **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](https://developers.google.com/pay/api/android/guides/test-and-deploy/integration-checklist#about-the-test-environment). ### Before you go live We recommend that you test the scenarios described in [Google Pay’s API reference for Android](https://developers.google.com/pay/api/android/reference/client) in your live environment. 1. Make sure that your API credential has the **API Clientside Encryption Payments role**. Check this in your [live Customer Area](https://ca-live.adyen.com/) or ask your Admin user to verify. 2. Go to your [live Customer Area](https://ca-live.adyen.com/) to configure your [Google Merchant ID](https://developers.google.com/pay/api/android/reference/request-objects#MerchantInfo). 3. Complete all the steps in the Google Pay API [deploy to production documentation for Android](https://developers.google.com/pay/api/android/guides/test-and-deploy/deploy-your-application). 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. ## Advanced flow Drop-in ## Requirements | Requirement | Description | | | -------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------- | - | | **Integration type** | Make sure that you have an existing Advanced flow [Android Drop-in integration](/online-payments/build-your-integration/advanced-flow?platform=Android). | | | **Setup steps** | Before you begin, [add Google Pay in your Customer Area](/payment-methods/add-payment-methods). | | ### Add Additional Configuration ## Add additional configuration for Google Pay [Add a configuration object](/online-payments/build-your-integration/advanced-flow/?platform=Android\&integration=Drop-in#3-optional-add-a-configuration-object) with the following parameters: | Parameter | Required | Description | | ---------------------------------- | -------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `setAllowCreditCards` | | Set if you support credit cards.
