| Field | Value | Conf | Note — and what a correct answer needed |
|---|---|---|---|
| Income and employment verification | Data — employee model | D | Employee has title, hired_at, employment_status, employment_type and compensation (type, amount, currency, frequency). A separate Verifications API routes to verification vendors, which is not payroll data. Source |
| Pay statements | Yes — Payslip | D | Payslip has gross_amount, net_amount, paid_at and typed details (EARNING_*, PRETAX_DEDUCTION_*, TAX_*, POSTTAX_*). Source |
| Tax forms | Generic 'TAX' document | D | The Document type enum includes 'TAX' and 'PAYSLIP'; there is no structured W-2 or 1099 model. Source |
| Direct deposit switching | Yes — bank account write | D | Bankaccount has routing_number, account_number, account_type and is_primary ('primary for direct deposit'), with POST and PUT endpoints. Per-integration support could not be read. Source |
| Deduction and benefit write | Yes — deduction CRUD | D | Deduction is 'Employee-specific deduction/benefit enrolment' (benefit_id, amount, FIXED/PERCENTAGE, frequency), with POST and PUT. Source |
| 401(k) and retirement | RETIREMENT benefit type | D | Benefit type includes RETIREMENT with employer_contribution fields; payslip details include PRETAX_DEDUCTION_RETIREMENT; deductions are writable. Source |
| Earned wage access | Data only | D | Timeshift has hours, start_at, end_at, is_approved and compensation; no EWA use case is marketed. Source |
| Data freshness | Live pass-through | D | 'Every API request hits the source platform directly'; employee data is not stored. Virtual webhooks poll for changes. Source |
| Permission and auth model | Embedded auth component | D | Pre-built components send end users to each integration's OAuth2 or API-token authorisation and return a connection ID. Source |
| Coverage claim (as stated) | 489 HR integrations | D | 'Explore supported features across 489 different HR & Directory integrations.' Source |
