Certn
Certn is a Canada-based, globally operating background check and identity verification platform. Its RESTful API lets HR, property management, gig, and marketplace platforms order and retrieve criminal record checks, identity verification, credit, employment, education, credential, and reference checks across 200+ countries, then receive results and adjudicated reports. The API authenticates with OAuth 2.0 client credentials (Client ID / Client Secret exchanged for a Bearer token) and pushes status updates via signed webhooks. The original api.certn.co v1 REST API is deprecated (discontinued 2026-08-05) in favor of the newer CertnCentric APIs; both are modeled here honestly.
