Quick Start

Recommended Pattern: Service Wrapper

For better testability and state management, we recommend wrapping the SDK in a service class:

using System.Collections.ObjectModel;

public interface IStoreService
{
    ObservableCollection<IaphubProduct> ProductsForSale { get; }
    ObservableCollection<IaphubActiveProduct> ActiveProducts { get; }

    Task InitializeAsync();
    Task<IaphubReceiptTransaction> BuyAsync(string sku);
    Task RestoreAsync();
    Task LoginAsync(string userId);
    Task LogoutAsync();
}

public class StoreService : IStoreService
{
    private readonly SemaphoreSlim _refreshLock = new(1, 1);

    public ObservableCollection<IaphubProduct> ProductsForSale { get; } = new();
    public ObservableCollection<IaphubActiveProduct> ActiveProducts { get; } = new();

    public async Task InitializeAsync()
    {
        await IaphubSdk.StartAsync(
            // Found in IAPHUB dashboard
            appId: "your-app-id",
            // Found in IAPHUB dashboard
            apiKey: "your-api-key",
            // Set to true to allow purchases without user login
            allowAnonymousPurchase: false,
            // Enable StoreKit V2 (recommended, requires App Store Server API configuration)
            enableStorekitV2: true
        );

        IaphubSdk.OnUserUpdate += async (s, e) => await RefreshProductsAsync();

        await RefreshProductsAsync();
    }

    private async Task RefreshProductsAsync()
    {
        if (!await _refreshLock.WaitAsync(0)) return;

        try
        {
            var products = await IaphubSdk.GetProductsAsync();

            ProductsForSale.Clear();
            foreach (var product in products.ProductsForSale)
                ProductsForSale.Add(product);

            ActiveProducts.Clear();
            foreach (var product in products.ActiveProducts)
                ActiveProducts.Add(product);
        }
        finally
        {
            _refreshLock.Release();
        }
    }

    public Task<IaphubReceiptTransaction> BuyAsync(string sku) => IaphubSdk.BuyAsync(sku);
    public Task RestoreAsync() => IaphubSdk.RestoreAsync();
    public Task LoginAsync(string userId) => IaphubSdk.LoginAsync(userId);

    public async Task LogoutAsync()
    {
        await IaphubSdk.LogoutAsync();
        ProductsForSale.Clear();
        ActiveProducts.Clear();
    }
}

Then register it in your DI container:

// MAUI (MauiProgram.cs)
builder.Services.AddSingleton<IStoreService, StoreService>();

Make sure to call InitializeAsync() when your app starts.
