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 9 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/extensiv: open an issue to ask a question, or submit a pull request to add artifacts.
