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.

Certn publishes 6 APIs on the APIs.io network, including Applications API, Checks API, Packages API, and 3 more. Tagged areas include Background Checks, Identity Verification, Criminal Record Check, Screening, and HR Tech.

Certn’s developer surface includes authentication, documentation, engineering blog, and 9 more developer resources.

Where this information came from

This is an independent, third-party profile of Certn, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
