Certn Webhooks
Outbound webhook delivery for asynchronous screening events. Certn posts JSON payloads containing applicant status, result, check_executions, enhanced_identity_verification, rcmp_result, information, and activity_log fields to a customer-configured endpoint configured in team settings. Payloads are signed with an HMAC-SHA256 `Certn-Signature` header carrying a timestamped signature (`t=,v1=`) to prevent replay attacks.
