Generate Barcode online using .NET REST API.

In a world increasingly reliant on information and seamless data exchange, the need for efficient barcode generation has never been more critical. Barcodes serve as a universal language for machines, simplifying processes across various industries. Whether it’s tracking inventory, managing sales, or enhancing security, barcodes play a pivotal role. In this guide, we’ll explore how to generate barcodes effortlessly using a powerful .NET REST API. Additionally, we’ll emphasize the importance of saving these crucial pieces of information in the widely compatible JPG format, ensuring seamless integration and accessibility across a plethora of applications and systems.

.NET REST API for Barcode Generation

Generating barcodes with precision and efficiency is made possible through Aspose.BarCode Cloud SDK for .NET. This robust software development kit simplifies the process of barcode creation, allowing you to seamlessly integrate barcode generation capabilities into your applications. It also provides the ability to decode barcodes from various image formats, enabling a comprehensive approach to barcode management. Whether it’s creating QR codes, UPC-A, Code 39, or many others, this SDK covers a wide array of barcode symbologies.

In order to use the SDK, first we need to search Aspose.BarCode-Cloud in NuGet packages manager and click the Add Package button. Secondly, we need to visit cloud dashboard, to obtain your personalized client credentials.

Given below is the explanation regarding above stated code snippet.

BarcodeApi barcodeApi = new BarcodeApi(configuration);

Firstly, initialize an instance of BarcodeApi class while passing the Configuration object as an argument.

var request = new GetBarcodeGenerateRequest(type, text)
    TextAlignment = "center",
    TextLocation = "Below",
    format = "JPG"

We have specified that the text in barcode shall be at the bottom of the image, center aligned and the output format shall be JPG.

Stream response = barcodeApi.GetBarcodeGenerate(request)

Call the API to generate the barcode of type Code39Standard.

using (FileStream stream = File.Create("BarcodeGenerated.jpg"))

A simple routine to save the resultant Barcode in JPG format to a local drive.

How to Generate Barcode using cURL Commands

Generating barcodes using Aspose.BarCode Cloud through cURL commands is a versatile and efficient method. cURL is a command-line tool widely used for making HTTP requests, making it an ideal choice for integrating with Aspose.BarCode Cloud API. Furthermore, with cURL commands, you can swiftly initiate barcode generation requests. This approach also enables you to automate and script the generation process, facilitating batch or repetitive barcode creation.

Now, please execute the following command to generate a JWT access token:

curl -v "" \
 -X POST \
 -d "grant_type=client_credentials&client_id=163c02a1-fcaa-4f79-be54-33012487e783&client_secret=c71cfe618cc6c0944f8f96bdef9813ac" \
 -H "Content-Type: application/x-www-form-urlencoded" \
 -H "Accept: application/json"

Once we have the JWT token, please execute the following command to generate a barcode and save the output on local drive.

curl -v "" \
-X GET \
-H  "accept: image/jpg" \
-H  "authorization: Bearer {accessToken}" \
-o "resultantBarcode.jpg"

Replace accessToken with JWT access token generated above.


In conclusion, generating barcodes is a crucial task with implications across various sectors, from inventory management to customer engagement. Both approaches, utilizing the comprehensive Aspose.BarCode Cloud SDK for .NET and leveraging the versatile cURL commands with Aspose.BarCode Cloud, offer powerful solutions. Nevertheless, both paths lead to an efficient barcode generation, empowering businesses to enhance data encoding, accessibility, and automation seamlessly.
