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 start, ensure you have the following:

Get Started

1

Installation

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

Quick Example: Scan Text

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

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.
