About Google Pay

How does it work?

Як відбувається процес покупки для клієнта через Google Pay


The user clicks the Google Pay payment button and sees a payment sheet with a list of supported payment methods.


The user selects a payment method and Google Pay securely returns a payment token for that method to your website.


Your website submits the payment token, along with details about the purchase, to its backend.


To execute the payment, the backend processes the purchase and sends the payment token to the payment service provider.

Integration with Google Pay step by step:

PSP XPAY offers Partners two ways to integrate Google Pay on their website:

  • payment page - checkout XPAY;

  • direct integration via Google Pay API.

Integration with the payment page allows Partners to get a "Google Pay" payment button without significant changes and heavy coding in payment processing. 

Direct integration through the Google Pay API requires refinement on the part of the Partner and requires compliance with Google's requirements and procedures.
