I’m a shopify App proxies developer, I know shopify will forward the proxy URL to me which is like
/proxy/extra/path/components?extra=1&extra=2&shop=shop-name.myshopify.com&logged_in_customer_id=1&path_prefix=%2Fapps%2Fawesome_reviews×tamp=1317327555&signature=4c68c8624d737112c91818c11017d24d334b524cb5c2b8ba08daa056f7395ddb
so I can get the domain in request query param ‘shop’, but in custom domain scene, i still get the domain like xxx.myshopify.com, how can i get the custom domain?
