Extensiv

Extensiv (formerly 3PL Central, rebranded in 2022) is a cloud-native omnichannel fulfillment software company for third-party logistics providers (3PLs) and brands. Its platform combines warehouse management (3PL Warehouse Manager and Warehouse Manager), order management, inventory management, and integration tooling - built from the combination of 3PL Central, Skubana, Scout, and CartRover. The flagship developer surface is the 3PL Warehouse Manager REST API (auth server at secure-wms.com/AuthServer), which exposes orders, inventory, items, customers, receivers/ASN, stock summaries, and warehouses to external integrators. Access is provisioned with Client ID / Client Secret credentials that mint short-lived bearer tokens. NOTE - the SecureWMS/3PL Warehouse Manager REST API itself is documented in more detail in the sibling all/3plcentral entry; this entry profiles the Extensiv company and platform and its relationship to that API.

Extensiv publishes 7 APIs on the APIs.io network, including Authentication API, Customers API, Inventory API, and 4 more. Tagged areas include 3PL, Warehouse Management, WMS, Order Management, and Inventory Management.

Extensiv’s developer surface includes authentication, documentation, engineering blog, and 8 more developer resources.
