I am having app where you can have stores(merchants) those who are using 2 payment providers. Merchant 1: order.example.com/<merchantId 1 > Merchant 2: order.example.com/<merchantId 2> Both the payment gateways their own payment processing certificates. So i assume to configure two payment processing certificates, i need to create two apple pay MIDs in my dev portal. Or can i use one MID and configure both? if yes, please mention how to do it the next question is about the domain association. I am having a single backend hosting all the merchant sites mentioned in above. If i have to MIDs, which means there are to domain association files that needs to be hosted in the server's welknown directory. Could you mention the possibilities of resolving above issue >
