you can listen to paymentmethod event [0] and check the paymentMethod details which contains the billing details like name, email etc [1] which you can use for the validation.

[0] https://stripe.com/docs/js/payment_request/events/on_paymentmethod
[1] https://stripe.com/docs/api/payment_methods/object?lang=go#payment_method_object-billing_details

that's how you can do the validation

but make sure you call complete function to close the Google Payment sheet before you call the update

paymentRequest.on('paymentmethod', function(ev) { 
.....
ev.complete('fail'); 
...
// update 
})
