Clean Harbors Customer Portal (CLH SaaS)
Clean Harbors Online Services (CHOS) — the authenticated web portal where customers create waste profiles, raise drum and bulk service requests, manage on-site waste inventory, and retrieve manifests, shipping documents, reports and invoices. Human login only: there is no token endpoint, no OpenID Connect discovery document (/.well-known/openid-configuration returns 404) and no documented programmatic access. The company publishes quick-reference guides for it but no API.
