SLVZ.Billing.Myket 1.0.3

📦 SLVZ Billing Myket

SLVZ Billing Myket is a lightweight and easy-to-use .NET library for handling in-app purchases via Myket on Android.
It simplifies the integration of the Myket payment system for .NET MAUI apps without needing to write any Java code directly.

✨ Features

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

⚙️ Installation

Install-Package SLVZ.Billing.Myket

⚙️ Usage Example

1. Initialize the library

using SLVZ.Billing;

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

InAppBilling.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

using SLVZ.Billing;

var result = await InAppBilling.Purchase("coin_pack_1" , "Optional payload");

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

3. Purchase a subscription

using SLVZ.Billing;

var result = await InAppBilling.Subscription("coin_pack_1" , "Optional payload");

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

4. All availible items to purchase

using SLVZ.Billing;

var items = await InAppBilling.AllAvailibleItems();

It will return all subs and purchase items with details

5. Consume a product (for repeatable items)

using SLVZ.Billing;

var result = await InAppBilling.Consume(purchaseModel);

if (result.Status)
    Console.WriteLine($"Item '{result.ProductID}' Consumed");

6. Data Models (PurchaseModel)

public class PurchaseModel
{
    public string? productId { get; set; }
    public string? purchaseToken { get; set; }
    public JsonElement? 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; }
}

7. 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 InAppBilling.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 Myket 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.
• Make sure to declare all your product IDs when calling Initialize().
• All callbacks return strongly typed models (PurchaseModel, ItemModel) for simplicity.
