How to Generate an EAN-13 Barcode as a PNG File

EAN barcodes are the one of most commonly used barcode variants worldwide. With our EAN-13 generating API, you can validate and generate new barcodes as PNG files for your business in the blink of an eye. Below, you can take advantage of snippets provided in Java to easily make a custom-code connection for your business.

Start by installing the Java SDK with Maven. Add the below reference to the repository found in pom.xml:

<repositories>
    <repository>
        <id>jitpack.io</id>
        <url>https://jitpack.io</url>
    </repository>
</repositories>

Next up, add a reference to the dependency:

<dependencies>
<dependency>
    <groupId>com.github.Cloudmersive</groupId>
    <artifactId>Cloudmersive.APIClient.Java</artifactId>
    <version>v4.25</version>
</dependency>
</dependencies>

Now to finish — add in the import classes & the barcode-generating function, then include your Cloudmersive API key:

// Import classes:
//import com.cloudmersive.client.invoker.ApiClient;
//import com.cloudmersive.client.invoker.ApiException;
//import com.cloudmersive.client.invoker.Configuration;
//import com.cloudmersive.client.invoker.auth.*;
//import com.cloudmersive.client.GenerateBarcodeApi;
ApiClient defaultClient = Configuration.getDefaultApiClient();
// Configure API key authorization: Apikey
ApiKeyAuth Apikey = (ApiKeyAuth) defaultClient.getAuthentication("Apikey");
Apikey.setApiKey("YOUR API KEY");
// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)
//Apikey.setApiKeyPrefix("Token");
GenerateBarcodeApi apiInstance = new GenerateBarcodeApi();
String value = "value_example"; // String | Barcode value to generate from
try {
    byte[] result = apiInstance.generateBarcodeEAN13(value);
    System.out.println(result);
} catch (ApiException e) {
    System.err.println("Exception when calling GenerateBarcodeApi#generateBarcodeEAN13");
    e.printStackTrace();
}

Just like that, you’re ready to generate new barcodes.
