About Google Pay API

Supported features

The Google Pay API has several supported features.

Supported forms of payment

The Google Pay API may return cards or network tokens.

Recurring billing and subscriptions

Support for recurring billing is tied to the payment method returned in the Google Pay API response. Both tokenized cards and cards on file can be used for recurring billing. To process recurring billing, the merchant doesn't have to call our API at a cadence. Rather, the payment credential is stored on the merchant side for recurring payments. The merchant uses their payment gateway APIs to manage recurring billing.

Google Pay supports recurring payments if the following statements are true:

• Merchants comply with network rules, such as merchant-initiated transactions.
• Terms of payment are disclosed and accepted by the user within the merchant’s buyflow.

We also support recurring billing with variable amounts. For example, monthly phone bills for mobile carriers are supported. To get more information, merchants must contact their payment gateway representative.

Auto-reload or "top-up"

To process an auto-reload charge for the same cost, the merchant doesn't have to call our API each time. The payment credential is stored on the merchant side and reused. To get more information, merchants must contact their payment gateway representative.

Chargebacks

Merchants can handle transaction reversals for cancellations, reimbursements, or disputes in the manner that they currently handle chargebacks for other forms of payment. To get more information, merchants must contact their processors representative.

Donation collection

Approved nonprofit organizations (NPOs) can integrate the Google Pay API to collect donations, if, and only if, they provide documentation to prove, certify, and validate their nonprofit status. For example, US NPOs must provide valid 501(c)3 status proof from the IRS in order to qualify.

General FAQ

The following FAQ apply to merchants.

I use a major PSP to manage all risk and Strong Customer Authentication. What should I know about GPay?

The Google Pay API returns payment methods in a signed and encrypted payload. The returned payment methods consist of either PAN or tokenized cards made of device PAN (DPAN) and cryptograms.

Tokenized card payloads are processed without additional step-up or challenge.

Card payloads that consist of PAN require 3D Secure through an in-house or a PSP-provided solution.

If your PSP manages all the risk and SCA logic, make sure that your Google Pay API integration includes the following properties:

• merchantInfo.merchantName (Android, Web): The merchant name is rendered in the payment sheet.
• transactionInfo.countryCode (Android, Web): This indicates where the transaction processes. You must specify the acquirer bank country.
• transactionInfo.totalPrice (Android, Web): The total monetary value of the transaction with an optional decimal precision of two decimal places.

How can merchants promote Google Pay acceptance in their apps and sites to their users?

To highlight support for Google Pay, make sure to use the assets available in our Android and Web brand guidelines.

If you have an Android integration, you can note in the Play Store description that you now support Google Pay. For web integrations, you can directly add a description to the merchant website.

Can ecommerce platforms support Google Pay?

Yes, Google Pay API supports onboarding ecommerce platforms. Payment processor, gateway, or ecommerce platform partners that host a checkout page on behalf of their merchants can use Google Pay’s hosted checkout feature.

See our Find supported payment methods for in-store and contactless purchases page for a list of countries and the banks in each that support Google Pay tokens (CRYPTOGRAM_3DS). Both supported and unsupported cards are listed.

What's the difference between Google Play In-app Billing and the Google Pay API?

Google Play developers that sell digital goods and services on Android apps must use Google Play In-app Billing, as specified in the Play Developer Policy Center. Examples of In-app Billing include virtual game products, app functionality or content, and cloud software products. See the Google Play Billing overview page to learn more about In-app Billing.

When used in apps, the Google Pay API is only available for physical products and services.

Does Google Pay charge any fees?

Google Pay doesn't additionally charge users, merchants, and developers additional fees to use the Google Pay API for payments. Merchants, specifically, continue to pay processing fees to their payment processor.

What does Google do to validate credentials and prevent fraud?

All cards added to Google go through a verification authorization to validate card details, which include the card verification code (CVC). Google also runs a proprietary risk engine based on instrument data, Google account profiles, purchase history, locations, and device information. Merchants, however, must continue to use their current fraud and risk assessment tools with Google Pay transactions.

Does the Google Pay API integration work in WebViews?

For Android apps which use WebViews, you must invoke platform specific Android Google Pay APIs. See Binding JavaScript code to Android code for examples.
