We're in the process of updating our Windows SDKs. The content below relates to our previous version. Please contact our support team if you wish to implement Windows in-app checkouts or licensing.
1 Add to project
Include the PaddleSDK.dll file into your project. If using Visual Studio this can be done by choosing “Add Reference…” and browsing to the DLL.
2 Integration code
To get started you will need to create an instance of the Paddle client. We recommend using the CreateSharedInstance method to create a single instance that can be statically referenced throughout your application via
public static Paddle CreateSharedInstance(string apiKey, long vendorId, string productId)
public partial class MainForm : Form
var paddle = Paddle.CreateSharedInstance("298c1c56fa2c2733220d54fdf211ea49", 13578, "503866");
