The Dieline Dimensions API gives you the flat outside dimensions of a packaging dieline as a list of parts, in milliseconds, for any set of variables.
It is built for the pricing and quoting step: a webshop, configurator or quoting tool can ask for the technical size of a packaging dieline, at any dimensions the customer configures, and calculate a printing price from the result. No file is drawn or exported — you get only the sizes.
Every response is a part_list — always an array of part objects, each with a name, a category, and a bounding_box (its flat width and height in the unit you requested):
name: "default").Each part's bounding_box is the assembled footprint of one copy of that part — the exact measurement it takes to lay out and print it. Request area: true and each part also carries its flat material area — the true area of its cut shape, not width × height.
You request the parts of a dieline template, identified by its dieline_template_id (for example "becf-11a02"). Browse the catalog with the discovery endpoints to find a template and the variables it accepts.
Try it for free. The demo template becf-11101 accepts custom dimensions and does not consume credits on either the sandbox or the production API.
