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.
