PixelsPerModule
Required
Default value: 20
Number of pixels per module. For example, 20 pixels per module will result in an image approximately 400x400px.
No
Content
Required
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.
No
PrimaryColor
Default value: #000
The colour of the code pattern. Must be a valid HEX code.
No
SecondaryColor
Default value: #FFF
The colour of the code background. Must be a valid HEX code.
No
EnableMargin
Default value: true
Adds a margin around the outside of the QR code. Otherwise known as the quiet zone.
No
ErrorCorrectionLevel
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.
No
Size
Default value: 150
Size of QR code, specified in pixels
No
Heading
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.
Yes
Subtitle
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.
Yes
FileType
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.
No
License
License key, required to avoid watermark and use paid license features.
Yes
Automation Script Support
If you're using our Airtable automation script, you can use all of the above customisations. Simply append any of the above values to the URL specified within the script. For example, the snippet below adds support for the Heading and Subtitle fields:
// Fetch the field and value for the heading field
let headingContentField = table.getField(“Your Heading Field");
var headingContent = record.getCellValueAsString(headingContentField);
​
// Fetch the field and value for the subtitle field
let subtitleContentField = table.getField(“Your Subtitle Field");
var subtitleContent = record.getCellValueAsString(headingContentField);
​
// Update the 'url' below to include support for the heading and subtitle fields
// Note the addition of '&heading=' + encodeURIComponent(headingContent) + '&subtitle=' + encodeURIComponent(subtitleContent)
updatedRecord.fields[imageAttachmentField.name] = [
    {
        url: 'https://qrcodegenerator.api.littleappy.co/api/qrcode/basic?Content=' + encodeURIComponent(content) + '&heading=' + encodeURIComponent(headingContent) + '&subtitle=' + encodeURIComponent(subtitleContent) + '&FileType=Png&ErrorCorrectionLevel=' + errorCorrectionLevel + '&PixelsPerModule=20&License=' + encodeURIComponent(licenseKey),
        filename: record.id + ".png"
    }
];
