UPC/EAN 5-digit extension barcode API

What UPC/EAN 5-digit extension is for

The 5-digit extension sits to the right of a UPC or EAN barcode. Book publishers use it for the suggested retail price, with the first digit giving the currency.

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/upcextension5?text=90200&label=true" \
  -H "Authorization: Bearer bc_live_your_key" -o upcextension5.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/upcextension5?label=true&text=" & GetAsURLEncoded ( Items::Code ) ;
  cURL options: "--header \"Authorization: Bearer " & $$BARCODE_KEY & "\"" ]

What it accepts

Exactly 5 digits. Example: 90200

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.
