Google Pay

Add Google Pay to android apps for these supported countries.

Important

The following Google Pay payments receive liability shift in SCA impacted regions:

Mastercard
Visa (where device PAN/"CRYPTOGRAM_3DS" is used)

Get started

Read through the GooglePay Overview.
Ask your Implementation Manager to enable Google Pay.
Your Implementation Manager supplies you with a Gateway Merchant ID which you need to supply in your integration with Google Pay API.
Follow the GooglePay tutorial and complete the GooglePay test checklist to ensure a successful integration.

Important

*You must set the allowedAuthMethods card parameter to "CRYPTOGRAM_3DS" as described here. This is to ensure only network tokens and cryptogram are passed in a tokenized card payload. This means no step-up challenge is required.
To be SCA compliant, you must provide the country code in your request to the Google Pay API when you process in an SCA impacted region.

Google Pay payment request

Here is an example of a Google Pay authorization request. For more information on taking a Google Pay payment take a look at our Payments API documentation.
