QRGen API - A Dynamic QR Code Image Generator

Introduction

QRGen is an API that enables you to create custom dynamic QR Codes that are optimized for North American mobile camera phones. Based on the data payload we have optimized the compression, size, and error correction code parameters. Our goal is to make it as easy and painless as possible for you to embed dynamic QR Codes in to your application.

Usage

  • *We now support HTTPS (SSL) for integration of QR Codes with secure websites.
  • Include the following in an <IMG> tag as if it were an image location .../qrgen?... examples and parameters are listed below.

PHONE CALL

Raw Data

Advanced Parameters

By default QRGen will automatically compute the optimum values targeted for North American phones based on the data provided. For some background as to what these parameters do we recommend you read http://www.denso-wave.com/qrcode/aboutqr-e.html

Width

The desired width of the image. If none is supplied the width of your image is determined by the size parameter. We advise using this parameter rather than trying to fiddle with the size parameter.

  • Parameter Type: numeric
  • Valid range: 15-500

Ecc

This determines the error correction level of the QR code. We strongly recommend that you let us pick which ECC level to use. If you insist on picking it yourself please read "Error Correction" on http://www.denso-wave.com/qrcode/qrgene2-e.html.

  • Parameter Type: character
  • Valid Range: H, Q, M, L

Cap

This is some text rendered just beneath the QR Code in bold text. It should be something short, like a title for the QR code.

  • Parameter Type: string

Subcap

This is some text rendered just beneath the main caption. It can be a little bit longer than the caption but you don't have a lot of room to work with. Note that subcaptions can be hard to read if your QR code width is less than 300 pixels.

  • Parameter Type: string

NoCap

Instructs the generator to disable the subcaption.

  • Parameter Type: numeric
  • Valid Range: 0 - 1

Color

Generate image using this color foreground.

  • Parameter Type: string
  • Hexadecimal string representing RGB color values: RGB(0,0,255) = '0000FF'

Background Color

Generate image using this color background.

  • Parameter Type: string
  • Hexadecimal string representing RGB color values: RGB(255,0,0) = 'FF0000'

MMS/Email Tags

Generate a tag for the free MMS/EMail QR code decoding service.

  • Parameter Type: numeric
  • Valid values:
    • 0 - Tag is turned off.
    • 1 - Tag is rendered in arrow style.
    • 2 - Tag is rendered in sidebar style.
