POS cart app extension
You can extend your apps into Shopify Point of Sale to perform actions on the cart. We're starting with the loyalty program use case, allowing merchants to redeem customer loyalty points and apply promotions to the cart. To set up the POS cart app extension the following steps are required:
- Configure the app extension in the Partner Dashboard by specifying the path segment that will be appended to the app’s base URL.
- Create the POS cart app extension endpoints so your app can receive requests from Shopify. Shopify uses REST calls and structured JSON to communicate with your app.
