My doubt is which one domain comes in the Header, params Shopify-Shop-Domain, the documentations said in the description:
"The permanent domain of the merchant's shop. Can be used to identify which shop is initiating the payment."
Referent: https://shopify.dev/apps/payments/processing-a-payment
If I change the default domain(myname.myshopify.com) to a custom domain(myname.com) which one comes like Shopify-Shop-Domain in PaymentProcess?
