This guide will walk you through installing the official C# SDK and running your first scan. In just a few minutes, you’ll be able to check content for plagiarism, AI-generated text, and more directly from your .NET application.

🔑 Before you begin

In order to start integrating Copyleaks API, you'll need an account and an API key:

• Don't have an account? Sign up for free
• You can find your API key on the API Dashboard

🚀 Get Started

1. Installation

   First, install the official Copyleaks package from NuGet into your project using the Package Manager Console.

   Install-Package Copyleaks

2. Quick Example: Scan Text

   Caution

   Remember to replace the placeholder credentials and webhook URL with your actual values.

   Program.cs

   using System;
   using System.Text;
   using System.Threading.Tasks;
   using Copyleaks.SDK.V3.API;
   using Copyleaks.SDK.V3.API.Models.Requests;
   using Copyleaks.SDK.V3.API.Models.Requests.Properties;
   
   public class Program
   {
       // --- Your Credentials ---
       private const string USER_EMAIL = "YOUR_EMAIL_ADDRESS";
       private const string USER_KEY = "YOUR_API_KEY";
       private const string WEBHOOK_URL = "https://your-server.com/webhook/{STATUS}";
       // --------------------
   
       public static async Task Main(string[] args)
       {
           try
           {
               // Log in to the Copyleaks API
               Console.WriteLine("Authenticating...");
               var identityClient = new CopyleaksIdentityApi();
               var loginResponse = await identityClient.LoginAsync(USER_EMAIL, USER_KEY);
               Console.WriteLine("✅ Logged in successfully!");
   
               // Prepare your content for scanning
               Console.WriteLine("Submitting text for scanning...");
               var apiClient = new CopyleaksScansApi();
               var scanId = Guid.NewGuid().ToString();
               var textToScan = "Hello world, this is a test.";
               var base64Content = Convert.ToBase64String(Encoding.UTF8.GetBytes(textToScan));
   
               // Configure the scan
               var scanProperties = new ClientScanProperties();
               scanProperties.Sandbox = true; // Turn on sandbox mode for testing
               scanProperties.Webhooks = new Webhooks { Status = new Uri($"{WEBHOOK_URL}") };
   
               var fileDocument = new FileDocument
               {
                   Base64 = base64Content,
                   Filename = "test.txt",
                   PropertiesSection = scanProperties
               };
   
               // Submit the scan to Copyleaks
               await apiClient.SubmitFileAsync(scanId, fileDocument, loginResponse.Token);
               Console.WriteLine($"🚀 Scan submitted successfully! Scan ID: {scanId}");
               Console.WriteLine("You will be notified via your webhook when the scan is complete.");
           }
           catch (Exception ex)
           {
               Console.WriteLine($"🛑 An error occurred: {ex.Message}");
           }
       }
   }

3. Understanding the Code

   The example code performs four main actions to submit a scan:

   1. Login: It authenticates with your email and API key to get a secure login token. This token is required for all subsequent requests.
   2. Prepare Content: It takes a simple string of text and converts it into a Base64 string.
   3. Configure Scan: It creates a ClientScanProperties object to define the scan’s behavior. We enable sandbox mode for safe testing and provide a webhook URL for completion notifications.
   4. Submit for Scanning: It creates a FileDocument with the content and properties, then sends it to the Copyleaks API. The process is asynchronous; Copyleaks will notify your webhook URL once the scan is complete.

🗺️ Next Steps

Now that you’ve submitted your first scan, here are some recommended steps:
