This is not our API. This repository is an independent, third-party profile of a company's publicly available API surface, maintained by API Evangelist. API Evangelist does not operate, host, resell, or support this company's APIs, and is not affiliated with or endorsed by the company unless stated on the profile.
Where the information came from. Everything here is assembled from material a member of the public can reach with a browser and no credentials — the company's own website, developer portal and documentation, the specifications it publishes for public use (OpenAPI, AsyncAPI, JSON Schema,
apis.json,llms.txtand similar), its public repositories, and its public status, pricing and changelog pages. Nothing here is obtained by breaching a system, defeating an access control, or using credentials of any kind.The rating is an independent assessment. The Kin Score and Agent Readiness rating are independently calculated scores of a company's public API artifacts, produced by API Evangelist against a published rubric. They are not certifications, endorsements, security assessments, or audits, and they score published artifacts — not the quality, safety, or security of the software.
Corrections, re-scores, and removal are free. No partnership, contract, or purchase is required, and you do not need to justify the request.
- Something wrong? Open an issue on this repository, or email info@apievangelist.com.
- Published something new? Ask for a re-score and we will re-run the rating.
- Want the listing taken down? Say so and we will honor it. The profile is reduced to your company name, a factual description, and a link to your own site, and the company is recorded as unrated — never scored zero for having asked.
Response times. Acknowledgement within one business day; removal or restriction within two business days; corrections and re-scores within five business days.
Not from the company, and here with a question? You are welcome here — we would rather be the front line and point you the right way than have a good report go nowhere. What this repository can answer is narrow, though, so it is worth knowing who you are actually looking for:
- A question about how the API works, an account, billing, or a bug in the service — that is the company's own support, not us. We profile this API; we do not operate it and cannot see your account.
- A bug in an open-source project we only catalog — file it on that project's own repository. This has happened with a real and correct bug report that reached us instead of the people who could fix it, which helped nobody.
- Anything about this listing itself — the description, the tags, the rating, a missing or wrong artifact — is ours. Open an issue here.
- Not sure, or something general about API Evangelist or APIs.io — open an issue on the APIs.io Inbox and we will route it.
This repository contains no software, and we will never ask you to download anything. There is no build, release, installer, or binary here — only text and machine-readable API descriptions, so there is nothing here that can be "corrupt" or need "repairing". Any issue, comment, or email claiming otherwise and offering a download link is not from us and is hostile. Do not follow the link; it is a lure. Report it to GitHub and, if you like, tell us at info@apievangelist.com so we can take it down.
On a security or compliance team? Email info@apievangelist.com with security in the subject line and you will get a person, not a form. We will tell you exactly which public URLs this profile was built from so your team can see the same surface we did, and we will take the listing down on request while you work through it.
Full detail: Where this data comes from
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 SKU items and inventory, read stock summaries and stock details, submit and track inbound receivers (Advance Ship Notices / ASN), and enumerate customers, warehouses/facilities, and locations.
Authentication is OAuth 2.0 client-credentials: Base64-encode clientId:clientSecret, POST it as a Basic Authorization header to https://secure-wms.com/AuthServer/api/Token with a JSON body of {"grant_type":"client_credentials","user_login_id":<id>}, and use the returned short-lived bearer token (typically valid 30-60 minutes) on all other calls. Collection endpoints are paged with pgnum/pgsiz and filterable with Resource Query Language (RQL). All traffic must use HTTPS.
Relationship to
all/extensiv: This entry documents the 3PL Warehouse Manager product specifically — the SecureWMS REST API. It is meant to be complementary to, not a duplicate of, the broaderall/extensivcompany entry. Extensiv is the parent company whose suite also spans Order Management, Integration Manager, Fulfillment Marketplace, and Warehouse Analytics;all/extensivcovers the company/suite level, whileall/3plcentralstays scoped to the 3PL Warehouse Manager / SecureWMS API.
