How to get PaymentGateWayURL when connecting the gateway to Apple Pay?

Could you please tell me where can I get PaymentGateWayURL who wants Apple Pay integration with website.

Now I read the Doc from the alpha Bank there is that you sign a certificate signed by the Bank, but what in the end you will have gateWayURL - no one says anything.

It needs to return Apple Pay in the request session (ApplePaySession), specifically in the handler onvalidatemerchant
After which it is possible to conduct a request for validation of the seller, specifying the certificate, key, and ID
