Checkr

Checkr is a technology-driven background check platform for employment screening. Its REST API lets employers, staffing firms, and platform partners run compliant background checks programmatically - creating candidates, sending invitations, ordering packages, and retrieving reports composed of individual screenings (SSN trace, county/state/national/federal criminal searches, sex offender registry, motor vehicle records, education and employment verifications, and more). The API also covers adverse action workflows, continuous checks and subscriptions, node/hierarchy and geo account structure, Form I-9, documents, and webhooks for event-driven report status updates. Authentication is HTTP Basic auth with a secret API key, with OAuth for Checkr Partner integrations.

Checkr publishes 14 APIs on the APIs.io network, including Account API, Adverse Actions API, Candidates API, and 11 more. Tagged areas include Background Checks, Employment Screening, Compliance, HR Tech, and Identity Verification.

Checkr’s developer surface includes authentication, documentation, and 9 more developer resources.
