Google Pay

The Tietoevry E-Commerce Payment Gateway (EGW) provides native support for Google Pay, enabling merchants to accept fast, secure, and tokenized payments from Android and Chrome users. Google Pay simplifies the checkout experience by removing the need for manual card entry and leverages stored credentials with biometric authentication to ensure high conversion and strong security.

Google Pay – Gateway Owner Responsibility

To enable Google Pay for live transactions, the Gateway Owner (e.g., Bank or PSP) must register and manage the Google Pay Merchant account. This includes:

• Registering a valid Google Pay Merchant ID

• Accepting the terms of use for Google Pay APIs

• Ensuring adherence to Google’s branding and usage guidelines

These responsibilities apply to both deployment models:

• Managed Service – Tietoevry handles technical integration, but legal/commercial enablement is the responsibility of the Gateway Owner.

• On-Premises – The Gateway Owner is accountable for the full setup and regulatory registration with Google.

Integration via EGW

Google Pay is supported through both the EGW Hosted Checkout Page and API-based integrations, with all required token handling and scheme compliance managed by EGW. Merchants benefit from streamlined onboarding and simplified compliance requirements.

Integration Highlights:

• Hosted Checkout: - Google Pay button appears automatically for eligible browsers and devices.

• API-Based Checkout - Merchants using custom checkout can integrate via Google Pay JS and route payment tokens through EGW.

• Tokenized Transactions - Uses Visa Token Service (VTS) and Mastercard MDES for secure, network-based tokenization.

• Merchant Registration - Managed by Tietoevry; no direct setup with Google is required from the merchant.

Customer Checkout Flow

1. Customer selects Google Pay on the checkout page.

2. Google Pay interface opens with pre-filled card and address data.

3. Customer authenticates using biometrics or device passcode.

4. EGW processes the token and completes the transaction securely.

5. Real-time confirmation is provided on the site or in the app.
