This tutorial demonstrates how to generate QR codes with a C# REST API. You’ll create a QR‑code generator using the C# Low Code API combined with the Aspose.BarCode Cloud SDK for .NET, and discover how to fine‑tune every property of the resulting QR‑code image for complete customization.
Prerequisite
- Create an account and get API credentials for creating a QR Code
- Download Aspose.BarCode Cloud SDK for Dotnet to generate a QR Code in an image
- Set up a C# project with the above SDK
Steps for QR Code Builder with C# REST Interface
- Include Aspose.BarCode Cloud SDK API and model classes
- Initialize the configuration with API base URL, client ID, and client secret
- Specify the file name where the QR Code image will be saved
- Create an instance of GenerateApi using the configured settings
- Call the GenerateAsync method to create a QR Code with the desired text and image format
- Open a file stream to prepare for writing the generated QR Code image
- Copy the generated QR Code stream into the file for storage
These steps summarize the process for a 2D code generator with C# .NET-based API. First, set up the Aspose.BarCode Cloud SDK by configuring your API credentials and choosing a file name for the QR Code. Then, generate the QR Code with your desired text and format, and save it to a file for use.
Code for QR Builder using C# RESTful Service
Now that you’ve seen the example, you have a complete QR‑tag generator built with a C# REST API. By invoking GenerateAsync(), you can create a barcode or QR code asynchronously—simply provide the text to encode along with any optional settings such as style, size, colors, or rotation. The method assembles the request, sends it to the service, and returns the finished code as a stream ready for saving or immediate use.
By following these steps, you’re now equipped to generate QR codes effortlessly with the C# REST API. Ready to create barcodes too? Check out our companion guide Generate barcode with C# REST API.
