Pack and Quote API

Before checkout or fulfillment, retailers, wholesalers, and distributors need a package estimate before shipping rates can be quoted reliably. Weight-only rules, fixed tables, or guessed cartons may be enough for some orders, but they can break down when item quantity, item mix, box choice, dimensional weight, or carrier-service assumptions change. SolvingMaze Pack and Quote API uses item, quantity, box, and destination data to estimate package configurations, return packing lists, and when requested, return package-carrier rates for those estimated packages.
Pack and Quote API

Submit item, quantity, box, and destination data from a shopping cart, WMS, ERP, or custom fulfillment system to calculate packing lists. When carrier rates are requested, return UPS, FedEx, USPS, DHL, and Spee-Dee package rates 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.
