Frequently Asked Questions
You set the expiration when issuing the certificate. Our StatusList automatically updates when the date passes. No cron jobs, no manual revocation — the certificate simply stops verifying.
Yes. LMS platforms with native webhook support (Docebo, Cornerstone, Absorb, Litmos) can trigger automatic certificate issuance on course completion. For other platforms, use our API SDKs to build custom integrations.
Our certificates include all required OSHA fields: training date, trainer info, topics covered, and completion status. Auditors can verify instantly without requesting paper records.
Contractors receive their certificate as a QR code or digital card. When they arrive on-site, security scans the code — instant verification of current training status.
You configure reminder emails (30 days, 7 days, etc.). If the employee doesn't recertify, the credential stops verifying. Anyone checking their status sees 'expired' — no manual tracking needed.
