Integration checklist

Use the following checklist to ensure you've completed all of the required steps in your Android integration.

About the test environment

Our test environment doesn't return live chargeable tokens in the PaymentData response, but the test environment allows us to test elements of your purchase:

  • Confirmation pages
  • Receipts
  • Billing address (optional)
  • Billing phone number (optional)
  • Shipping address (optional)
  • Email address (optional)

An Unrecognized App error appears on the Google Pay payment sheet until your app has production access.

The value of the environment parameter from WalletOptions indicates whether the server runs in a production or in a test environment. The environment value can be one of the following:

  • WalletConstants.ENVIRONMENT_PRODUCTION
  • WalletConstants.ENVIRONMENT_TEST

For testing and development, use WalletConstants.ENVIRONMENT_TEST.

Test your integration

Before you submit your integration to Google for validation in ENVIRONMENT_TEST, ensure that you've fulfilled the exit criteria for each of the following functional and brand checks.

1. Basics

Ensure that your current risk checks and controls for card or PAN transactions are also applied to the Google Pay transactions. Google Pay validation and fraud checks aren't intended to replace your risk management processes.
Ensure that you've read and are ready to accept our Terms of Service. Registration with the Google Pay API requires that you have access to the account owner email address of your Android application.
Use the data received from the Google Pay API to process transactions only. All other use cases require separate, express consent from the user.
Confirm the payment card authentication and card networks are accepted by the payment processor in your country.
If you complete a DIRECT tokenizationSpecification type integration, you must annually rotate your public encryption key and provide PCI Attestation to Google via the Business Console. PCI Attestation can be submitted by a third-party or Qualified Security Assessor certified by the PCI Security Standards Council, and approved by an Approved Vendor or Qualified Assessor.

2. Branding tests

Use our approved assets and adhere to all elements of our Brand guidelines.
Ensure the Google Pay payment button only appears after your app has confirmed the user's ability to pay through the isReadyToPay() function.
Confirm that the displayed Google Pay payment button dimensions match similar buttons and elements on the page.
Choose an appropriate button based on the background color of the area where it's intended to appear.

3. Functional tests

When you request a CARD payment method type with PAN_ONLY card authentication, complete the cards on file test:

  1. If applicable, remove all cards from the Google Pay Android application.
  2. If applicable, remove all cards on file from pay.google.com.
  3. Return to your integration.
  4. Click Google Pay.
  5. Validate that you see the option to add a card.
  6. Add a card from a supported network, as defined in allowedCardNetworks.
  7. Validate that you see the added card with a network logo in the selector.

When you request a CARD payment method type with CRYPTOGRAM_3DS card authentication, complete the Android device token test:

  1. Check that your card issuer is supported, and add an eligible card in the Google Pay Android application.
  2. Return to your integration.
  3. Click Google Pay.
  4. Validate that you see the added card with card art in the chooser.

If you've confirmed that your processor supports CRYPTOGRAM_3DS card authentication, you might proceed, even if CRYPTOGRAM_3DS card authentication isn't available to you as an Android user or cardholder.

If you require a shipping address, test processing of the shipping address in varied states of completion. Try the following methods:

  • Test variances on a full name to be parsed into structured fields, such as John, John Doe, and Jane Doe Smith.
  • Accurately parse all address lines returned by the Google Pay API, which might exceed the total number of address lines typically collected in your standard checkout flow.
  • Verify that the returned country component of the address matches your site's supported shipping destinations. If you specified shipping restrictions, enter an unsupported shipping address and verify it's not allowed in the Google Pay payment sheet.
If you require a telephone number, test the parse and storage of the telephone number to the data standards of your app for different formats such as +14155551212, 14155551212, (415) 555-1212.
Ensure that Google Pay is displayed on parity with other third party payment methods.
For users who don't have any payment information stored on their account within your app, Google Pay should be defaulted or shown prominently as the payment method.
For users who previously selected Google Pay at checkout and indicated Google Pay as their preference for payment within your app, Google Pay should be the default payment method for their subsequent purchase.
A final price must be displayed to the user before the transaction is processed. If the amount to be charged has varied based on data received from the Google Pay API you're expected to show a confirmation page with a final price.
