Hosted Checkout
The easiest way to use Google Pay is by using the Dintero checkout solution, where we handle the whole payment flow for you. If you are already using Dintero checkout you just need to enable Google Pay.
Getting started
To use Google Pay as a payment method you have to ensure you follow Google Pay APIs Acceptable User Policy and accept Google Pay APIs Terms of Service.
You also have to set up a Dintero account.
Enable Google Pay on your Dintero account
During your onboarding, Google Pay will generally be enabled as a payment method by default. If it's not enabled, you can go to settings and payment methods. There you can enable Google Pay as a payment method for your account. If you use payment profiles ensure that Google Pay is added to the relevant profiles.
Authentication methods
Google Pay can provide both cards on file (PAN_ONLY) or device tokens (CRYPTOGRAM_3DS). Device tokens are bound to an Android device and authenticated with a 3-D Secure cryptogram. Both authentication methods are supported for hosted checkout.
3-D Secure
Device tokens will generally not require 3-D Secure authentication as they are already authenticated, while PAN_ONLY will generally require 3-D Secure authentication. For hosted checkout we will handle 3-D Secure for you, both determining if it is required as well as handling the authentication flow.
Testing
Sandbox Environment
If you enable test mode and create a payment with Google Pay, you will get a dialog where you can select the card with the desired behavior. This uses a Google Pay sandbox to simulate getting a payload from Google Pay.
The test payments will not charge any cards.
Production Testing
Once you are ready to test in production you can enable Google Pay for production and try payments. Note that this will actually charge your card, but you can cancel or refund the payment after testing.
If you want to avoid exposing Google Pay to customers while testing in production you can set up a payment profiles and add Google Pay to a profile that isn't used for customers.
