Using app extensions with Shopify POS
Merchants can use Shopify POS to sell in person with Shopify. Merchants can use Shopify POS to create a cart for each customer, customize the cart in several ways, and then accept payment with a range of payment methods. With the Shopify POS App SDK you can extend or add new features to Shopify POS for the iPad.
There are three types of integrations with the POS SDK: full-screen apps, Edit Cart, and Order Completion. Full screen apps are launched from the App Grid, which is accessed through the Apps button on the side navigation menu. All installed apps appear on the grid and become tappable buttons. The other three integrations make use of a specific UI element where you can integrate your app. You can find out more information on these integrations below.
App extensions can be setup from the pages of your partner Dashboard as described below.
