Integrate Google Pay into your checkout flow with Cardflo. This allows customers to pay quickly and securely using stored card details across Android devices and Chrome browsers.
Google Pay helps accelerate the payment process, reducing cart abandonment by offering a familiar and efficient payment option.
Enabling Google Pay through a Cardflo-connected gateway reduces checkout friction and improves conversion rates for mobile transactions. This one-tap payment solution simplifies the purchase journey and tackles issues of drop-off caused by complex payment processes.
Google Pay overview
Google Pay serves as a digital wallet and payment platform that facilitates card-not-present transactions by utilising payment credentials stored in a user's Google Account. Within the payments stack, it acts as a container for various funding sources, including credit, debit, and prepaid cards.
When a customer initiates a transaction, Google Pay generates a virtual account number or a cryptogram, depending on whether the merchant is using network tokenisation or encrypted payloads. This mechanism abstracts the primary account number from the merchant environment, which can reduce the scope of PCI DSS compliance.
For the acquirer and issuer, Google Pay transactions are processed via standard scheme rails, often benefiting from the security protocols of the underlying mobile device.
The system supports both web-based integrations through Chrome and in-app experiences on Android, using the Google Pay API to pass encrypted payment data through a gateway to the relevant card scheme.
How google Pay works
Customer initiates payment session
The customer selects the Google Pay button within a merchant's checkout or mobile application. The Google Pay API displays a payment sheet where the customer chooses their preferred card and confirms the transaction. Identification often relies on biometric data or device passcodes to verify the user.
Encrypted payload generation
Once authorised by the user, Google generates an encrypted payment token or a dynamic cryptogram. This payload contains the necessary card information or a network token, along with transaction-specific data, ensuring that the actual primary account number is not exposed directly to the merchant's server during the transmission.
Gateway transmission and decryption
The merchant sends the encrypted payload to their PSP or gateway. The gateway decrypts the data to identify the card details or passes the network token directly to the acquirer. This step ensures that the transaction remains within the established secure rails for card processing.
Issuer authorisation and settlement
The acquirer submits the authorisation request to the issuing bank via the card scheme. The issuer validates the cryptogram and checks for available funds. Upon approval, an authorisation code is returned, and the transaction is eventually captured for settlement within standard industry timeframes.
Why google Pay matters
Friction reduction and conversion
By removing the requirement for manual data entry of card numbers, expiry dates, and CVVs, Google Pay minimises the mechanical hurdles at the point of purchase. In mobile-first environments, these friction points often lead to cart abandonment. Digital wallets allow for a compressed checkout experience that can lead to higher successful authorisation rates compared to traditional manual entry.
Advanced security through tokenisation
Google Pay utilises network tokenisation where available, replacing the physical card secondary account number with a device-specific token. Because these tokens are typically restricted to a specific merchant or device, the risk of fraudulent use following a data breach is significantly reduced. This architecture aligns with modern security standards and protects the integrity of the payment lifecycle.
Google Pay use cases
Android grocery basket checkout
Grocery applications using the Google Pay API must confirm payment quickly before reserved delivery slots or time-sensitive stock allocations expire. Cardflo routes Google Pay network tokens from Android biometric flows to suitable acquirer partners, while reporting links each authorisation, capture and refund to the merchant’s basket reference.
Android sportsbook account funding
Licensed sportsbook operators accepting Google Pay deposits on Android must apply player limits and gambling controls without delaying pre-event account funding. Cardflo routes the network token to acquirer partners that support the operator’s MCC and market, while transaction references help finance teams reconcile deposits, reversals and withdrawals.
Google Pay event ticket checkouts
Stadium ticket sellers face concentrated Chrome checkout traffic when allocated seats and short-lived reservations are released for major fixtures. Cardflo routes Google Pay network tokens through multi-acquirer routing, helping operators manage authorisation traffic while holding on to order references for later voids, partial captures and event refund reconciliation.
Google Pay by the numbers
Typical industry observations suggest that digital wallets can reduce the time spent in the checkout flow by several minutes compared to manual card entry.
Industry reports often indicate a measurable uplift in conversion rates on mobile devices when one-tap payment methods like Google Pay are implemented.
Merchants using network tokens via digital wallets often see a marginal increase in authorisation rates due to reduced friction and better card life-cycle management.

Questions about Google Pay
Which Google Pay API components are required for Chrome checkout integration?
Chrome checkout integration uses the Google Pay JavaScript API to check availability, present the payment sheet and return an encrypted payment data response. The merchant configuration defines supported card networks, authentication methods and the gateway parameters required by Cardflo.
A server-side payment request then passes the returned payload into Cardflo for validation and submission through the appropriate regulated acquirer partner.
How should Android apps pass Google Pay payment data to Cardflo?
An Android app requests payment data through the Google Pay API and receives an encrypted payment method payload after the customer confirms the transaction.
The app should send that payload, the order reference, amount and currency to the merchant’s server rather than attempting to interpret sensitive fields locally. The server submits the request to Cardflo, where it is validated and routed through the configured acquirer partner network.
How do Android biometric checks affect the Google Pay checkout flow?
Google Pay may require the customer to unlock or verify on the Android device before releasing payment data, depending on the device, stored credential and issuer requirements.
That verification occurs within the Google Pay flow, so merchants should not build a separate biometric capture step into the checkout. The resulting payment request can still be subject to additional authentication or issuer checks when required by the transaction context.
Can Google Pay be used for recurring or merchant-initiated transactions?
Yes, Google Pay can be used to facilitate the initial customer-initiated transaction (CIT). During this process, the merchant or their gateway can obtain a token that is used for subsequent merchant-initiated transactions (MIT).
This is a common practice for subscription models, allowing the merchant to bill the customer at regular intervals without requiring the customer to be present for every billing cycle.
How does Google Pay help reduce chargebacks or disputes?
While Google Pay does not provide an absolute guarantee against chargebacks, the use of device-level authentication (biometrics/passcodes) provides stronger evidence of cardholder participation compared to simple CVV checks.
In cases where network tokenisation and cryptograms are used, the risk of 'lost and stolen' fraud is significantly lowered. However, ‘friendly fraud’ or service-related disputes remain a possibility and are handled via the standard scheme dispute process.
What data does the merchant receive when a customer uses Google Pay?
The merchant receives the necessary information to complete the order via the Google Pay API response. This typically includes the payment cryptogram or token, the card brand and last four digits (for display purposes), and, if requested, the customer's shipping and billing addresses.
This reduces the need for the merchant to collect this data via manual forms, though the merchant remains responsible for processing this data in accordance with GDPR or other privacy regulations.
