Drata HRIS User Identities API
HR user identity records for a Custom HRIS connection. Use the batch upsert endpoint to submit employee records keyed by your own `identityId`, then use the update endpoint to reflect employment changes (e.g. set `separatedAt` when an employee leaves). Deleting a record is intended for data submitted in error, not for offboarding. Changes are not applied immediately — they are incorporated the next time identity sync runs, which happens nightly by default. A sync can also be triggered manually from the Personnel page.
