Checkr API
Background check and candidate screening platform for employment, gig economy, and tenant screening. API supports creating candidates, ordering background check packages (criminal, MVR, employment verification, drug screening), monitoring report status, and receiving webhook notifications when reports complete.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Handles extremely sensitive PII (SSN, criminal history). SOC 2 Type II certified. FCRA compliance is enforced at the product level. PII collection via hosted secure forms reduces server-side exposure. Single API key has no granular scope control.
⚡ Reliability
Best When
Building HR automation or gig platform onboarding that needs to programmatically order, track, and act on background check results with compliance safeguards built in.
Avoid When
You need instant results (criminal checks can take 1-5 business days), you're screening individuals in unsupported countries, or you're a small business that doesn't meet Checkr's permissible purpose requirements.
Use Cases
- • Automate pre-employment background screening in ATS or HRIS workflows
- • Trigger background checks for gig workers onboarding to marketplace platforms
- • Monitor background check report status and route results to hiring managers
- • Retrieve adverse action workflow steps for candidates who don't pass screening
- • Integrate continuous monitoring alerts for existing worker populations
Not For
- • Consumer self-directed background checks (Checkr is B2B only; requires business account)
- • Instant identity verification in real-time user flows (reports take hours to days)
- • International background checks in countries not supported by Checkr's network
Interface
Authentication
HTTP Basic Auth using API key as username with empty password. Separate keys for sandbox and production environments. OAuth available for Checkr Partner integrations (marketplace platforms connecting customer accounts).
Pricing
Production access requires business verification and permissible purpose attestation. Pricing is usage-based with no subscription fee, but a sales process is typically required for production access.
Agent Metadata
Known Gotchas
- ⚠ FCRA compliance requirements mean agents cannot auto-reject candidates based on report results — adverse action workflow is legally mandated and must be human-in-the-loop
- ⚠ Background check reports are not instant — agents must use webhooks or polling; report turnaround ranges from minutes to days
- ⚠ Sandbox and production environments have different API keys and different base URLs; easy to accidentally point at wrong environment
- ⚠ Candidate PII (SSN, DOB) must be submitted via a hosted iframe or secure tokenization — cannot POST raw SSN via server-side API in most integration patterns
- ⚠ Report statuses have multiple intermediate states (pending, consider, clear, suspended, dispute); agent state machines must handle all transitions
