This article provides an overview of the QR API, its core functionalities, and how it can be used to integrate QR Code generation into your systems.
QR API is a powerful tool that allows developers to integrate QR Code generation seamlessly into their applications, systems, or websites. With this API, you can create various types of QR Codes, including URL, text, vCard, and more, directly from your backend or server-side applications. This document will help you understand the basics of QR API and how it can be utilized effectively in your projects.
A. Getting Started with QR API
To start using the QR API, you need to have an account and obtain your API key. This API key is essential for authentication and must be included in your API requests.
- Step 1: Sign up on the QR API website and log in to your account.
- Step 2: Navigate to Get API Key section to retrieve your unique API key.
- Step 3: Use this API key in all your API requests as a header or query parameter for authentication.
B. Creating a Simple QR Code
Once you have your API key, you can start generating QR Codes. Here’s a simple example of how to create a QR Code using the API.
-
Endpoint:
/create-qr-code - Method: POST
-
Parameters:
-
data(string): The data to encode in the QR Code (e.g., a URL). -
size(optional, integer): The size of the QR Code in pixels (default: 300). -

Example request:
curl -X POST https://api.qrapi.io/create-qr-code \
-H "Authorization: Bearer YOUR_API_KEY" \
-d "data=https://yourwebsite.com" \
-d "size=300" \
-d "format=png"C. Handling API Responses
Each API request returns a JSON response containing the generated QR Code or error messages if the request fails. Here’s how to handle the responses:
- Success Response: Includes a URL to the generated QR Code image.
- Error Response: Includes an error code and message describing what went wrong.
Example response:
{
"status": "success",
"qrCodeUrl": "https://api.qrapi.io/qr/abc123.png"
