Certn Packages API

openapi: 3.2.0
info:
  title: Certn Applications Packages API
  description: 'Certn is a background check and identity verification platform. This API lets partner platforms (HR, property management, gig/marketplace) order background screening for applicants, retrieve consolidated reports, manage the checks and packages that make up a screen, and receive status updates via signed webhooks. Certn screens candidates across 200+ countries and territories.


    Authentication uses OAuth 2.0 client credentials: a Client ID and Client Secret (created in the Partner tab under API Keys) are exchanged for a Bearer access token that is sent on every request.


    Base URL is https://api.certn.co for production and https://demo-api.certn.co for the demo/testing environment.


    IMPORTANT - endpoint provenance: The original api.certn.co v1 REST endpoints (under /api/v1/hr, /api/v1/pm, /api/v1/users, /api/v2/teams) are documented and CONFIRMED against the public reference, but Certn deprecated them on 2026-04-13 with discontinuation on 2026-08-05 in favor of the newer CertnCentric APIs. The CertnCentric documentation portal (centric-api-docs.certn.co) is a client-rendered SPA whose exact endpoint paths could not be scraped; its resource groupings (cases, checks, reports, packages, webhooks) are MODELED here honestly and marked with x-endpoint-status. Confirm all shapes against the live docs before use.'
