Posso executar a aplicação web FooSales no meu próprio domínio?

Yes, the FooSales web app is bundled with the plugin. If you were previously accessing the web app at https://web.foosales.com you can launch the bundled web app directly from your WordPress admin dashboard by clicking the Launch POS button from the FooSales menu. Authentication is handled automatically and any cross-origin resource sharing (CORS) issues should no longer be an issue since any server requests will be performed on your store’s same domain.
