Buku Hub API
The Buku Hub API is the developer side of Buku: a single REST API that connects your platform or warehouse to Buku's enterprise carrier network. Shop pre-negotiated enterprise rates across carriers in one call, purchase and void labels, and track every shipment — without carrier swaps or WMS migrations for your customers.
One request rate-shops a shipment across the organization's connected accounts and Buku's 24 direct carrier and provider integrations — domestic, regional, and international — at pre-negotiated enterprise pricing.
Purchase, void, and batch labels at scale, with manifests and end-of-day close built in.
Register trackers and receive normalized, carrier-agnostic status updates pushed to your endpoint.
Register your customers' own carrier accounts by API (owner-authorization steps handled by Buku-hosted pages), estimate international duties and taxes before checkout, and read metered billing statements and transactions.
How it works
Authorize your application for an organization and register its carrier accounts. Customers keep the carriers and workflows they already have.
Shop enterprise rates and purchase labels through one consistent API.
Follow every shipment with trackers and webhook push updates.
