Publishers and API
Is there an API for publishers and printers?
Answer
Yes. With the Barcode Rocket API, publishers and printers make barcodes straight from their own title system: one per call, or up to 100 in one call as a ZIP. It uses the same engine as the site, and keys are issued by Barcode Rocket, starting with a trial key.
How to start
- Read the API documentation.
- Ask for a trial key. It returns the PNG preview only, up to 100 previews a day, so you can connect your system.
- When you are ready, we send a live key. It returns print-ready PDFs.


What it can do
- One barcode per call, as a vector PDF or a PNG preview.
- Up to 100 barcodes per call, each with its own price, in one ZIP with an errors.csv for lines that are not valid. Live keys only.
- Custom templates made for your house, enabled for your key only.
Good to know
Keep the key on your server and never put it in a web page or an app. If a key leaks, tell us and we revoke it at once.
Price
Live keys, volume and house templates are paid services, agreed in writing case by case and billed by invoice. See the Terms, section 11 (Paid services).
