How to use your barcode generator URL
Learn how to build barcode image URLs using your personal generator key, pass barcode parameters, and test the service.
Find your URL in “My Barcodes”
On the My Barcodes page you will find a separate generator URL for each barcode type you have access to, such as Linear Barcodes, DataMatrix, QR Code and PDF417.

The key parameter identifies your personal access to the production barcode generator, which creates regular barcodes rather than DEMO-marked images. Get your actual key from My Barcodes after registration; YOUR_KEY above is only a placeholder.
Add barcode parameters after the key
Append the parameters you need after key=YOUR_KEY, separating each additional parameter with &. The generator returns a barcode image based on those values.

Try the demo generators
You can test BCMaker before using your production URLs. The following demo generator endpoints do not require your personal key:
Demo endpoints are for testing. Use your account-specific production generator URLs when you need normal, non-demo barcode images.
