Can international clients make purchases during my live event?

If you are using the integrated checkout solution with Shopify, depending on how your shipping zone is set up on your Shopify Admin, the Livescale platform will apply the same shipping zone rule options.

However, if you are using the redirected (no code) checkout solution, anybody can buy from your store, provided that you ship to that country, because they are redirected to your website directly. In other words, all your custom eCommerce rules will apply.
