3PL Warehouse Manager

3PL Warehouse Manager is the flagship cloud warehouse management system (WMS) built for third-party logistics providers, now sold under Extensiv and historically known as "3PL Central". Its public integration surface is the SecureWMS REST API (base https://secure-wms.com), used to create and retrieve orders, manage items and inventory, read stock summaries and stock details, submit and track inbound receivers (ASN), and enumerate customers, warehouses/facilities, and locations. Authentication is OAuth 2.0 client-credentials against https://secure-wms.com/AuthServer/api/Token, returning a short-lived bearer token (typically valid 30-60 minutes). This entry documents the 3PL Warehouse Manager / SecureWMS API specifically; the broader Extensiv company (which also spans Order Management, Integration Manager, Fulfillment Marketplace, and Warehouse Analytics) is tracked complementarily under the all/extensiv company entry.

3PL Warehouse Manager publishes 9 APIs on the APIs.io network, including Authentication API, Customers API, Inventory API, and 6 more. Tagged areas include Warehouse Management, WMS, 3PL, Logistics, and Fulfillment.

3PL Warehouse Manager’s developer surface includes authentication, documentation, engineering blog, and 9 more developer resources.
