Hello, this is a question about the new Shopify subscriptions app, we have been approved to test. Our developer is creating upsell/cross-sell functionality for our product, cart, and checkout pages and we would like to offer subscriptions as upsells for appropriate products during the purchase process. With the new Shopify subscriptions app will our developer have access to the appropriate APIs or other methods for adding a subscription item to the cart? If so, is there any documentation for that?
