Setup

The Google Pay API facilitates fast and easy online purchases. With the API set up, shoppers don't have to manually enter their payment information on your site. Instead, their payment information, such as their name, email, billing and shipping addresses, are already pre-entered in a payments selection dialog that's displayed to the shopper.
