Code 11 barcode API

What Code 11 is for

Code 11 encodes numbers and the dash in a compact linear barcode. Its main home is telecommunications, where it labels circuit boards and equipment.

Make one from a URL

Send the text and get the image back. Your API key goes in a header.

curl "https://barcode.fmdeploy.com/v2/barcode/code11?text=0123-4567&label=true" \
  -H "Authorization: Bearer bc_live_your_key" -o code11.png

Add &output=svg for a vector image that stays sharp at any print size.

From FileMaker

Insert from URL [ Select ; With dialog: Off ; Target: Items::Barcode ;
  "https://barcode.fmdeploy.com/v2/barcode/code11?label=true&text=" & GetAsURLEncoded ( Items::Code ) ;
  cURL options: "--header \"Authorization: Bearer " & $$BARCODE_KEY & "\"" ]

What it accepts

Digits and the dash. The check digit is added for you. Example: 0123-4567

If the text can’t be encoded, the API answers with a clear message instead of a broken image.

Options

Set the bar width with scale, the bar height with thickness, and turn the text under the bars on with label. You can also choose the label font and size, rotate the image in quarter turns, set the DPI stored in a PNG, or ask for SVG. The documentation lists every parameter and its default.
