Authenticate to the Rippling API using OAuth with time_off:read scope
GET /time_off/requests with status=approved and date range filters to retrieve all approved leave requests for the upcoming pay period
Resolve each request to the employee's HRIS record using the employee_id, and calculate hours or days of leave by type (vacation, sick, unpaid)
Subtract approved unpaid leave hours from the employee's expected scheduled hours and submit the adjusted hours to the payroll system
GET /time_off/balances after payroll runs to verify that leave usage has been deducted from accrual balances and matches the payroll input
Known gotchas
Approved requests may still be modified or cancelled after approval but before the payroll cutoff; always pull the latest status immediately before submitting payroll inputs rather than caching earlier approvals
Multi-day leave requests spanning pay period boundaries must be split at the period boundary so only the portion within the current period is included in the current payroll run
Rippling's time-off API may not include all leave types configured in custom policies; verify that all policy types relevant to payroll (especially unpaid leave) are returned by the API before relying on it as the system of record
