Learn how to generate a custom QR code with the C# REST API in a fast‑track, step‑by‑step tutorial. We’ll guide you through building a custom QR code generator using the C# Low‑Code API and the .NET‑based Cloud SDK, covering every required parameter, demonstrating QR‑code customizations, and showing you how to save the final output as an image on your local disk.
Prerequisite
- Create an account and get API credentials for generating custom QR codes
- Download Aspose.BarCode Cloud SDK for Dotnet to personalize QR codes
- Set up a C# project with the above SDK
Steps to Make Custom QR Code with C# REST Interface
- Start by adding the using lines so your program knows about the Aspose.BarCode Cloud classes
- Create a configuration object and give it the base API address, your client ID, and your client secret
- Make a GenerateApi object from your configuration so you can send barcode requests
- Set up the data you want to encode — in this case, a QR code containing a web link
- Pick colors, image type, rotation, resolution, and size for the barcode image
- Run the GenerateBodyAsync method with your settings to build the barcode image
- Open a new file stream called output.png to hold the generated image
- Copy the data from the generated barcode into your file so it’s saved on your computer
These steps outline the process for developing a custom QR generator using C# RESTful Service. First, connect your app to Aspose.BarCode Cloud by importing the right classes, setting up the configuration, and creating a GenerateApi object. Then you provide the QR code data, customize its look, generate the barcode, and save the resulting image as output.png on your computer.
Code to Customize a QR Code with C# .NET-based API
The example above shows how to create a custom barcode with C# REST API. By configuring the BarcodeImageParams section you control every visual aspect—colors, size, sharpness, format, and even rotation—enabling you to fine‑tune the output for any printing or display requirement.
That’s it—you now have a fully functional QR‑code generator powered by a C# REST API. When you’re ready to decode QR codes, check out our step‑by‑step guide on Scan QR code with C# REST API.
