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 API contracts indexed 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.

The Extensiv catalog on APIs.io includes 1 Spectral governance ruleset.

Extensiv’s developer surface includes authentication, documentation, engineering blog, and 12 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

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.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
MACH & Headless Commerce	builds-on	40.7	-	-
Amazon Seller Ecosystem (Selling Partner Appstore, Amazon Ads partners)	builds-on	40.7	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
