ISN

aid: isn
name: ISN
description: ISN Software Corporation, which trades as ISN, is a Dallas, Texas based contractor and supplier information management
  company founded in 2001. Its subscription platform ISNetworld collects, verifies and continuously monitors health and safety,
  quality, insurance, training, cybersecurity and sustainability data on contractors and suppliers, then connects that record
  to the hiring clients who engage them across energy, chemicals, manufacturing, mining, utilities, construction, food and
  beverage, and telecom. ISN operates in more than 85 countries from offices in Dallas, Midland, Calgary, Montreal, Toronto,
  Mexico City, London, Perth, Sydney, Auckland, Dubai and Paris, and also ships ISN Empower, a worker-facing mobile app and
  learning management tool. The company is employee owned; Blackstone took a significant minority stake in December 2020 at
  a valuation above USD 2 billion. ISN runs a production REST API at api.isnetworld.com that lets subscribers pull their own
  ISNetworld data into internal systems, but the API is documented only to customers and there is no public developer portal,
  OpenAPI description, or SDK.

  name: ISNetworld API
  description: The ISNetworld API is a RESTful, bearer-token authenticated HTTP API that lets ISN subscribers download their
    own ISNetworld data — company profile scorecards, connected contractor lists and related compliance records — for integration
    with internal systems. A client exchanges a UserKey and CompanyKey header pair at GET /token for a bearer token, validates
    it at GET /validate-token, and calls versioned resource paths under /1.0/. Requests must use TLS 1.2 or later. ISN publishes
    no OpenAPI description and no public reference; the Developer Integration Guide is issued to subscribers and the API's
    own help surface at /help is authentication-gated.

  detail: ISN runs a live production REST API at api.isnetworld.com — GET /token, /validate-token, /1.0/VendorConnections/ConnectedContractors
    and /1.0/CompanyProfile/Scorecard/{isnId} all answer HTTP 401 against a 404 control — but its only reference surface is
    the API's own /help endpoint, which is itself authentication-gated, plus a Developer Integration Guide PDF issued to subscribers;
    the word "API" does not appear anywhere on the public isnetworld.com site or in its 916-URL sitemap.
