Pack and Quote API

Before checkout or fulfillment, multi-item orders need a package estimate before shipping rates can be quoted reliably. Without that estimate, quotes often rely on order weight, fixed rules, or guessed cartons. SolvingMaze Pack and Quote API uses item, box, and destination data to estimate packages, return practical packing lists, and when requested, return shipping rates for those estimated packages.
Pack and Quote API

Submit item, box, and destination data from a shopping cart, WMS, ERP, or custom fulfillment system to calculate a packing list. When carrier rates are requested, return shipping quotes for the estimated packages.

Test Before Integration

Use the online Pack and Quote Tool to try API behavior in the browser, validate item and box setup, and review sample packing and optional rate output before writing integration code.

How Setup Works

Setup starts with three steps: configure boxes, add item dimensions and weights, then call the API with order and destination data.
