How to validate paymentMethod billing address fields

[rrigoni]

I'm following your examples here and I'm trying to validate the payment method billing address and display errors but only a generic error message is displayed in the PaymentRequest dialog saying There was an error while placing your order. Please try again!.

Displaying errors for the shipping address works just fine.

I'm trying to add the following error object for testing in the paymentRequest.retry(errors).

let errors = {
                paymentMethod: {
                    cardNumber: "asd",
                    cardholderName: "asd",
                    cardSecurityCode: "asd",
                    expiryMonth: "asd",
                    expiryYear: "asd",
                    billingAddress: {
                        addressLine: "asd",
                        region: "ads",
                    }
                }
            };

I tried to register the request.onpaymentmethodchange event but it never gets called.

Do you have an example on how to achieve that? Or any suggestion on the correct way to implement the billing address validation for the selected payment method?

Thanks

Hi @rrigoni , your code is correct, but Chrome currently does not implement retrying with payment method errors. Keep in mind that, even after Chrome implements it, it's up to individual payment apps to add support for this feature.

@romandev : I recall that you implemented the retry code (thank you!!!). Were you planning to add support for the paymentMethod field as well?

Thanks. So for basic-card it will also depend on Chrome to handle the error messages properly, right?

That is correct, but keep in mind that a 3rd party payment handler could also register as a basic-card provider.
