New to Shopify: checkout with your domain name!
You have probably noticed that since the end of July, the checkout is no longer done on a URL of the type checkout.shopify.com but with the domain name configured on your Shopify site.
Another good news for merchants using Shopify and which will further improve the user experience of their customers at the most crucial moment of the purchase funnel.
No configuration is necessary. This change has automatically been applied to all Shopify sites.
