QR Codes
Generate QR codes and have the image returned to you in the format you specify.

GET https://qrcodegenerator.api.littleappy.co/qrcode/basic
Creates and returns a QR code in the specified file format.
Query Parameters
Content*
String
The URL encoded content to be embedded within the generated QR code, such as a URL or text. This is what is displayed/used by QR code readers.
License
String
License key, required to avoid watermark and use paid license features.
PixelsPerModule
Double
Default value: 20 Number of pixels per module. For example, 20 pixels per module will result in an image approximately 400x400px.
PrimaryColor
String
Default value: #000 The colour of the code pattern. Must be a valid HEX code.
SecondaryColor
String
Default value: #FFF The colour of the code background. Must be a valid HEX code.
EnableMargin
Bool
Default value: true Adds a margin around the outside of the QR code. Otherwise known as the quiet zone.
ErrorCorrectionLevel
String
Default value: M Accepted values: Q, H, L, M Uses the Reed-Solomon Code to correct the QR code content if the code is partially unreadable (eg. through damage or dust). The higher the level, the more data is stored making the image larger.
Size
String
Default value: 150 Size of QR code, specified in pixels
Heading
String
Optional heading string that shows below the QR code. Truncation will occur if the string length is longer than the QR code, but this depends on the size of your QR code specified in PixelsPerModule and Size.
Subtitle
String
Optional subtitle string that shows below the QR code. Truncation will occur if the string length is longer than the QR code, but this depends on the size of your QR code specified in PixelsPerModule and Size.
FileType
String
Default value: Svg Accepted values: Svg, Jpg, Png, Gif, Ascii File format that the QR code is returned in. Note that some formats require a paid license, or may not support all functionality listed above.
EnableTransparentBackground
Bool
Default value: false
If true, SecondaryColor is ignored and a transparent background is used. Note that the export format must be PNG for this to work, as JPEGs do not support transparency. You also still need to send a background color in case a transparent background isn't possible.
