​
Overview

ZeroSettle provides native support for Apple’s StoreKit 2 framework, enabling developers to integrate payment incentives directly into their existing in-app purchase flows. Wherever StoreKit subscription transactions are supported, you can add a ZSCheckoutButton to offer incentivized checkout through ZeroSettle.

​
Implementation

Add the ZSCheckoutButton to your subscription or product purchase flow by providing the StoreKit product ID and user ID: 
import StoreKit
import ZeroSettle

ZSCheckoutButton(
    productId: "com.yourapp.premium.monthly",
    userId: currentUser.id
)

​
Integration Example

Here’s a complete example showing how to integrate ZeroSettle with your existing StoreKit purchase flow: 
import SwiftUI
import StoreKit
import ZeroSettle

struct SubscriptionView: View {
    let product: Product
    let userId: String
    
    var body: some View {
        VStack(spacing: 20) {
            // Your existing subscription UI
            Text(product.displayName)
            Text(product.displayPrice)
            
            // Add ZeroSettle checkout option
            ZSCheckoutButton(
                productId: product.id,
                userId: userId
            )
            
            // Or traditional StoreKit purchase
            Button("Buy with App Store") {
                Task {
                    try await product.purchase()
                }
            }
        }
    }
}

​
Technical Details

The ZSCheckoutButton component integrates directly with Apple’s StoreKit 2 SDK and ZeroSettle’s backend infrastructure to provide the following functionality: The button uses the provided productId to match against your StoreKit product configuration and the userId to identify the purchaser. When tapped, it initiates a ZeroSettle checkout flow that automatically applies any applicable incentive discounts configured in your dashboard.

​
Button Parameters

ZSCheckoutButton(
    productId: String,  // StoreKit product identifier
    userId: String       // Your app's user identifier
)
