MSI Plessey barcode API
Digits-only barcode used for shelf labels and inventory control in retail and warehouses.

What MSI Plessey is for
MSI, a variant of Plessey, is a numeric barcode used mostly on retail shelf-edge labels and for stock counts in warehouses.
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/msi?text=0123456&label=true" \ -H "Authorization: Bearer bc_live_your_key" -o msi.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/msi?label=true&text=" & GetAsURLEncoded ( Items::Code ) ; cURL options: "--header \"Authorization: Bearer " & $$BARCODE_KEY & "\"" ]
What it accepts
Digits only. A Mod 10 check digit is added for you. Example: 0123456
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.
