QR Code Generator API

"The simplest QR code generator API designed to generate 2D QR Codes. Qr code data are important for products inventory, shipment tracking, and storing important information."

About 2D QR Code

A 2D QR (Quick Response) code is a type of two-dimensional barcode that can encode a variety of data types, including text, URLs, contact information, and more. QR codes are similar to traditional 1D barcodes, but they can store much more information in a smaller space, and they can be read using a smartphone or other mobile device.

QR codes were first developed in Japan by Denso Wave, a subsidiary of Toyota, in 1994. They were originally designed for tracking parts in vehicle manufacturing, but have since become popular in a wide range of applications, such as marketing, payment systems, and authentication.

QR codes can store various types of data, including text, URLs, contact information, and even entire files. To read a QR code, you need a QR code scanner app on your smartphone or other mobile device. Once the app is open, you simply point your device's camera at the QR code, and the app will read the code and display the encoded data.

QR Code API Features

QR codes have become increasingly popular in recent years, as they can be used to quickly and easily share information and URLs, as well as for marketing and advertising purposes. For example, a QR code could be printed on a product label or in a magazine ad, and users could scan the code to access more information or to visit a website. This QR code generator API popular for QR code use in mobile tagging, personal information, URLs, phone numbers, vCard, Wifi sharing, and data sharing. QR Codes can contain large amounts of information in a small space. Following are some features:

  • Capable of containing virtually any data desired.
  • Popular for its use in mobile tagging and data sharing.
  • Can contain large amounts of data and can be spread throughout multiple barcodes.
  • Micro and Standard versions can be used to vary the size of the qrcode.

Your API Authentication Key

We use API keys to authenticate all the requests. You can view and manage your API keys in the My Account -> My APIs Center page. Your API keys can be used to access our all the APIs, So be sure to keep them secure. Do not share your secret API keys in publicly accessible areas such as GitHub, client-side code, and so forth.

                                                        XXXX-XXXX-XXXX-XXXX (login to see your free API Key)

API Base URL and Endpoints

The API Base URL serves as the foundation or root of the API's endpoints. It represents the common prefix shared by all API endpoints. An Endpoint URL represents a specific operation or resource provided by the API. It is appended to the API Base URL to form a complete URL for a particular API call.

Base URL:


Endpoint for QR Code Generator:

                                                    POST /qrcode 

API Request Method POST

This API use POST HTTP method to get data from our server. All API requests must be made over HTTPS ("S" stands for secure). Calls made over plain HTTP or without authentication key will not allowed.

Request Parameters

An API endpoint is a URL (Uniform Resource Locator) that is used to access a specific resource on a web server. API endpoints are the URLs that clients use to interact with a web API, and they typically consist of a base URL followed by a path that identifies a specific resource or action.

For QR code request

Parameter Description
This is your authentication api key to get requested data from our servers. This is mandatory parameter otherwise data request will be failed. Go to API Key.
This is barcode type. You can see the corresponding values of qr_type from this supported qrcode datatype list.
QR code posted data / information which you want to convert into QR code. You can see the corresponding format of qr_data for particular QR code type from this supported data format list.
This parameter used to set the Error Correction Level of QR code. The value should be from (L, M, Q, H). Default value is M.
This parameter used to set the matrix points size of QR code. The value range should be from (1 - 10). Default value is 4.
This parameter used to set the outer frame margin from generated QR code. The value range should be from (1 - 100) pixels. Default value is 2.
This parameter used to set image format of qrcode. The value should be in (png, jpg). Default value is png.

Example Post Data Request (in Json format)

    "key": "XXXX-XXXX-XXXX-XXXX (login to see your free API Key)",
    "qr_type": "1",
    "qr_data": {
        "tel": "+918888888888"

Response Format

API response format refers to the format in which data is returned from an API endpoint after a request is made. We use JSON format for API response data. JSON (JavaScript Object Notation): JSON is a lightweight data interchange format that is easy to read and write. It is widely used for API response data because it is easy to parse and manipulate in many programming languages.

QR Code Example Response

QR code response data in JSON format with base64 image and svg image string. You can store them into your database or use them directly into your project.

Also you can use Postman platform which enables you to create mock servers to assist with API development and testing. A mock server simulates the behavior of a real API server by accepting requests and returning responses. By adding a mock server to your collection and adding examples to your requests, you can simulate the behavior of a real API.
