To be an approved sales channel, your app must use the Sales Channel Account UI Kit for interface design and development. While the Embedded App SDK allows you to embed your sales channel directly inside of the Shopify admin, using resources in the Sales Channel Account UI Kit will enable your sales channel to also look and feel consistent with other sales channels and the rest of Shopify.
The UI Kit includes styled modules and components for merchant onboarding and account configuration within your sales channel, such as notice banners, setting controls, form inputs and modals. The UI Kit also outlines best practices for these design components to promote a consistent experience across Shopify admin for our merchants, making it easy for Shopify merchants to get started with using your sales channel.
