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

   The SDK requires Java 11 or higher. Add the official copyleaks-java-sdk dependency to your project’s pom.xml file.

   pom.xml

     <dependency>
         <groupId>com.copyleaks.sdk</groupId>
         <artifactId>copyleaks-java-sdk</artifactId>
         <version>4.3.0</version>
     </dependency>

2. Quick Example: Scan Text

   Caution

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

   ScanExample.java

   import classes.Copyleaks;
   import models.response.CopyleaksAuthToken;
   import models.submissions.CopyleaksFileSubmissionModel;
   import models.submissions.properties.SubmissionProperties;
   import models.submissions.properties.SubmissionWebhooks;
   import java.nio.charset.StandardCharsets;
   import java.util.Base64;
   import java.util.Random;
   
   public class ScanExample {
       // --- Your Credentials ---
       private static final String EMAIL_ADDRESS = "YOUR_EMAIL_ADDRESS";
       private static final String KEY = "YOUR_API_KEY";
       private static final String WEBHOOK_URL = "[https://your-server.com/webhook/](https://your-server.com/webhook/){STATUS}";
       // --------------------
   
       public static void main(String[] args) {
           CopyleaksAuthToken token;
           try {
               // Log in to the Copyleaks API
               System.out.println("Authenticating...");
               token = Copyleaks.login(EMAIL_ADDRESS, KEY);
               System.out.println("✅ Logged in successfully!");
   
               // Prepare your content for scanning
               System.out.println("Submitting text for scanning...");
               String textToScan = "Hello world, this is a test.";
               String base64Content = Base64.getEncoder().encodeToString(textToScan.getBytes(StandardCharsets.UTF_8));
               String filename = "test.txt";
               String scanId = Integer.toString(new Random().nextInt(100000));
   
               // Configure the scan
               SubmissionWebhooks webhooks = new SubmissionWebhooks(WEBHOOK_URL);
               SubmissionProperties submissionProperties = new SubmissionProperties(webhooks);
               submissionProperties.setSandbox(true); // Turn on sandbox mode for testing
   
               CopyleaksFileSubmissionModel submissionModel = new CopyleaksFileSubmissionModel(base64Content, filename, submissionProperties);
   
               // Submit the scan to Copyleaks
               Copyleaks.submitFile(token, scanId, submissionModel);
               System.out.println("🚀 Scan submitted successfully! Scan ID: " + scanId);
               System.out.println("You will be notified via your webhook when the scan is complete.");
   
           } catch (Exception e) {
               System.out.println("🛑 An error occurred:");
               e.printStackTrace();
           }
       }
   }

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 CopyleaksAuthToken object, which is required for all subsequent requests.
   2. Prepare Content: It takes a simple string of text and encodes it into Base64 format.
   3. Configure Scan: It creates a SubmissionProperties object containing SubmissionWebhooks to define the scan’s behavior. We enable sandbox mode for safe testing and provide the webhook URL.
   4. Submit for Scanning: It creates a CopyleaksFileSubmissionModel 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.
