Host the client billing payment form on a custom

Host the client billing payment form on a custom domain

Instead of webpayments.io (is a nice solution, but...) it would be better to have the possibility like the custom domain for customer but here for us. Setting up a CNAME record pointing webpayments.io and charge our customers within our own full domain name, that gives more trust to our customers and is more elegant and nice for us. For example "secure.example.com" when the customer receive the payment link
