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.

Where this information came from

This is an independent, third-party profile of 3PL Warehouse Manager, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
