BazaarPayment 1.0.1

📦 BazaarPayment

BazaarPayment is a lightweight and easy-to-use .NET library for handling in-app purchases via Cafe Bazaar on Android.
It simplifies the integration of the Bazaar payment system for .NET MAUI and Xamarin.Android apps without needing to write any Java code or use Poolakey directly.

✨ Features

• Supports both in-app purchases and subscriptions
• Simple, async-based API
• No extra dependencies required
• Works with .NET MAUI and Xamarin.Android
• Secure and easy to integrate

⚙️ Installation

Install-Package BazaarPayment

⚙️ Usage Example

1. Initialize the library

using BazaarPayment;

List<string> products = new() { "coin_pack_1", "subscription_premium" };

BazaarHelper.Initialize(this, "YOUR_RSA_KEY_HERE", products);

Initialize must be called once when the app starts (e.g., in your main Activity).

2. Purchase a product

var result = await BazaarHelper.Purchase("coin_pack_1");

if (result.Status)
    Console.WriteLine($"Purchase successful: {result.Product.productId}");
else
    Console.WriteLine("Purchase failed.");

3. Purchase a subscription

var result = await BazaarHelper.Subscription("subscription_premium");

if (result.Status)
    Console.WriteLine("Subscription activated!");

4. Query existing purchases/subscriptions

var purchases = await BazaarHelper.CheckPurchases();
var subscriptions = await BazaarHelper.CheckSubscriptions();

5. All availible items to purchase

var items = await BazaarHelper.AllInappItems();
var subs = await BazaarHelper.AllSubItems();

6. Consume a product (for repeatable items)

await BazaarHelper.Consume(purchaseModel);

7. Data Models (PurchaseModel)

public class PurchaseModel
{
    public string? productId { get; set; }
    public string? purchaseToken { get; set; }
    public string? state { get; set; }
    public string? payload { get; set; }
    public string? signature { get; set; }
    public string? orderId { get; set; }
    public string? originalJson { get; set; }
    public string? purchaseTime { get; set; }
    public string? type { get; set; }
}

8. ItemModel

Contains product details.

public class ItemModel
{
    public string? productId { get; set; }
    public string? description { get; set; }
    public string? price { get; set; }
    public string? title { get; set; }
    public string? type { get; set; }
}

⚠️ Notes

• Call BazaarHelper.Initialize() once before using any other methods.
• All operations are asynchronous — make sure to use await.
• If a purchase or subscription fails or is canceled, the returned Status will be false.
• Always validate the purchase signature on your server to ensure transaction integrity.
• The RSA key must match the one from your Bazaar developer panel.
• For consumable items, remember to call Consume() after a successful purchase.
• Do not call Initialize() multiple times — the helper automatically handles initialization state.
• The library depends on a small bridge layer (PoolakeyHelper) that must exist in your Android project.
• Make sure to declare all your product IDs when calling Initialize().
• All callbacks return strongly typed models (PurchaseModel, ItemModel) for simplicity.
