Baseline uses the largest box in the same stock list. DIM weight = L x W x H / 5,000 cm3/kg, an estimate, not a carrier quote. Download any request to reproduce it.
Package count and estimated dimensional weight answer different questions. An order may still need one package while using a smaller carton. That change can matter where a carrier bills by size, but the estimate is not the final charge: your service, rate card, divisor and rounding rules still apply. Compare both measures rather than treating a higher fill percentage as a saving by itself.
Each tab uses a different order mix, with the item quantities shown under Inspect items. The two drawings use the same coordinate scale so the carton sizes can be compared directly. Changing a tab changes the products and stock, not a live customer shipment. Use the examples to identify a packing decision your team wants to evaluate, then adapt the downloadable request to its own goods and cartons. Compare recent orders using your actual carton stock.
StoaPack is an API for an existing order or inventory system. Your OMS or WMS remains the source of stock data; StoaPack uses the details you send to return a packing plan. The API guide includes request fields, a working cURL example and response structure.
Operations and engineering can review, share or render the same concrete plan.
Send each site's inventory and box list. The response includes a shipping site and package plan for the units it can supply.
Use supported UN references to flag separation conflicts and quantities for review alongside the proposed packages.
Use supported instructions to separate items, assign a box type or set a fill cap for room reserved around the goods.
Declare a container's usable interior so eligible small items can be planned inside it as part of the outer package.
Send item sizes, weights and quantities with site stock and available cartons; the API guide shows the request and returned plan.
For engineering teams
