This page gives instructions for setting up Google Pay™ with embedded fields. This option lets a customer use any payment method stored in their Google account. When selected, Google returns a payment token that you can use in lieu of card details, providing your customers another safe and easy option for payment.

Google Pay™ with embedded fields has the following benefits:

• Versatile - Supported on all major web browsers. (Maast does not currently support Android integrations.)
• Flexible - Simply use embedded fields to collect payment information from your customers, or integrate with Google Pay™ to request the payload from the Google server.
• Secure - All cardholder data is collected and processed by Maast, a PCI DSS certified Level 1 compliant Service Provider.
