Employees endpoints

The employee register plus absence (frånvaro), vacation balances and year close, and payroll cutover opening balances. Running payroll itself: salary-runs.md.

Conventions (auth, envelope, pagination, dry-run, idempotency, standard errors) are in SKILL.md and are not repeated per endpoint.

GET /api/v1/companies/{companyId}/employees

List employees for a company. scope:payroll:read · risk:low · idempotent

Returns active employees in created-first order. Pass ?include_inactive=true to include soft-deleted (is_active=false) rows. Use ?search to match against first or last name. Personnummer is masked (birthdate visible, last-4 hidden); use GET /employees/{id} for the full value.

Use when: You need a roster: for building a UI picker, resolving employee_id before adding to a salary run, or syncing an external HR system. Do not use for: Fetching a single employee you already know the id of: use GET /api/v1/companies/{companyId}/employees/{id}. Salary calculations live on /salary-runs/{id}.

Pitfalls:

• Inactive employees are hidden by default; soft-delete via DELETE sets is_active=false (BFL 7 kap retention).
• personnummer is masked in the list response (GDPR Art.5(1)(c) data minimisation). The detail endpoint returns the full value.
• salary_type drives which field is meaningful: monthly_salary for monthly, hourly_rate for hourly. The other is null.

POST /api/v1/companies/{companyId}/employees

Create an employee. scope:payroll:write · risk:low · idempotent · dry-run · reversible

Creates a new employee for the company. Requires Idempotency-Key (UUID). Supports ?dry_run=true for input validation without committing. The personnummer in the request body must be 12 digits (ÅÅÅÅMMDDNNNN); the response echoes a masked form (birthdate + XXXX): GDPR Art.5(1)(c).

Use when: You need to register a new employee before adding them to a salary run. Use dry-run first to catch validation errors (missing tax table, salary amount, F-skatt mismatch) before committing. Do not use for: Updating an existing employee (PATCH instead). Soft-deactivating (DELETE: sets is_active=false). Hard-deleting (the API does not expose hard delete; BFL 7 kap retention).

Pitfalls:

• Idempotency-Key is mandatory: calls without it return 400 VALIDATION_ERROR.
• personnummer must be exactly 12 digits with the YYYYMMDD prefix (not the short 10-digit form).
• Duplicate personnummer within a company returns 409 EMPLOYEE_DUPLICATE_PERSONNUMMER. Personnummer is unique per (company_id, personnummer).
• For A-skatt employees who are not sidoinkomst, tax_table_number is required (29-42).
• salary_type drives which salary field is required: monthly_salary for monthly, hourly_rate for hourly.
• The response masks personnummer; never echo back the supplied value. Detail endpoint (deliberate drill-in) returns the full value.

GET /api/v1/companies/{companyId}/employees/{id}

Get a single employee. scope:payroll:read · risk:low · idempotent

Returns the full employee record including the 12-digit personnummer, bank details, tax configuration, and contact info. This is the deliberate drill-in for an id you already know: list calls mask personnummer.

Use when: You have an employee id and need every field (tax table, bank account, vacation rule): typically to render an edit form or to construct a payroll calculation input. Do not use for: Rosters or pickers (use the list endpoint: personnummer is masked there).

Pitfalls:

• The response includes the full personnummer. Treat it as a national identifier (GDPR Art.5(1)(c)): do not propagate it to logs or external systems beyond what your integration strictly requires.
• Inactive (soft-deleted) employees are returned by the detail endpoint; check is_active if your flow should skip them.

PATCH /api/v1/companies/{companyId}/employees/{id}

Update an employee. scope:payroll:write · risk:low · idempotent · dry-run

Partial update of an employee. Only the fields supplied in the body are changed. Supports ?dry_run=true to validate the merged record without committing. Personnummer changes are NOT permitted via this endpoint: the natural-person identity is immutable post-creation.

Use when: You need to change tax configuration, bank details, salary amount, or contact info on an existing employee. Do not use for: Changing personnummer (not supported: create a new employee if the natural-person identity changes, which is a rare edge case). Soft-deleting (use DELETE).

Pitfalls:

• personnummer in the body is ignored by this endpoint. To change it you must DELETE and recreate.
• salary_type changes require the matching salary field in the same request: switching to monthly without monthly_salary returns 400.
• tax_table_number changes only take effect on future salary runs; runs already in review or beyond use a frozen snapshot.

DELETE /api/v1/companies/{companyId}/employees/{id}

Soft-delete an employee. scope:payroll:write · risk:low · idempotent · dry-run · reversible

Sets is_active=false. The row is preserved because past salary runs reference it via salary_run_employees and those verifikationer are räkenskapsinformation under BFL 7 kap (BFL retention attaches to the verifikationer themselves, not strictly to the personnummer attribute on the master row). Hard delete is never exposed.

Use when: An employee has left the company and should no longer appear in active rosters or default to new salary runs. Do not use for: Reactivating later (PATCH is_active=true instead). Hard-deleting (not supported: retention).

Pitfalls:

• Idempotent: deleting an already-inactive employee returns 204 No Content (the same as the first call).
• The row is NOT removed from the database: re-creating with the same personnummer returns 409 EMPLOYEE_DUPLICATE_PERSONNUMMER even after soft-delete.
• Past salary runs still reference this employee; their data continues to surface in GET /salary-runs/{id} and SIE exports.

Parameter	In	Type	Required	Notes
companyId	path	string	yes
id	path	string	yes

Response 204.

GET /api/v1/companies/{companyId}/employees/{id}/absence

List absence days for an employee in a date range. scope:payroll:read · risk:low · idempotent

Returns per-day absence rows (sick, vab, parental, ...) between ?from and ?to (inclusive, max 92 days). No cursor pagination: the bounded range is the page. Optional ?type filter.

Use when: You need an employee's registered absence: to reconcile with an external time-tracking system, to verify what the salary engine will derive, or to display a calendar. Do not use for: The derived pay impact (karensavdrag, sjuklön lines): that lives on the payslip detail after :calculate. Worked hours for hourly staff: separate register, not on v1 yet.

Pitfalls:

• Ranges over 92 days return 400 ABSENCE_RANGE_TOO_LARGE: iterate quarters instead.
• A day can carry multiple rows with different absence_type values (e.g. half-day sick + half-day vab).
• Rows may reference the salary run that consumed them via salary_run_employee_id.

Parameter	In	Type	Required	Notes
companyId	path	string	yes
id	path	string	yes

Response 200:

{
  data: { salary_absence_day_id: string, absence_date: string, absence_type: "sick" | "vab" | "parental" | "pregnancy" | "care_relative" | "study" | "unpaid_leave" | "other_leave", hours: number, notes: string, salary_run_employee_id: string, created_at: string, updated_at: string }[],

PUT /api/v1/companies/{companyId}/employees/{id}/absence

Register absence for an employee over a date range. scope:payroll:write · risk:low · idempotent · dry-run · reversible

Expands [from, to] (max 92 days) to per-day rows and upserts them on the natural key (employee, date, type). Weekends are skipped unless include_weekends=true. Single day = from == to. Idempotent by construction: replaying the same PUT converges on the same rows.

Use when: "Anna was sick 3-7 March": one call registers the whole event. Also for pre-cutover history backfill when migrating from another payroll system (any past date is legal; imported sick days feed the karensavdrag lookback). Do not use for: Vacation day REQUESTS/approval workflows (out of scope). Editing hours on one existing day inside a range: PUT the single day (from == to) with the new hours.

Pitfalls:

• Weekends are skipped by default: pass include_weekends=true for schedules that span them.
• Upsert REPLACES the (date, type) rows in the range: hours/notes are overwritten, not merged.
• A day whose combined absence + worked hours exceed 24h returns 409 ABSENCE_HOURS_CONFLICT and the whole range is rejected (atomic).
• Registering absence does not recompute an open salary run: call POST /salary-runs/{id}/calculate afterwards.

DELETE /api/v1/companies/{companyId}/employees/{id}/absence

Delete absence days for an employee in a date range. scope:payroll:write · risk:low · idempotent · dry-run

Deletes per-day absence rows between ?from and ?to (inclusive), optionally filtered by ?type. Returns deleted_count (200, not 204) so callers can verify how many rows went.

Use when: An absence event was registered by mistake or ended early: "Anna came back Thursday, delete Thu-Fri sick days". Do not use for: Correcting hours on a day: PUT the day again instead. Rows already consumed by a BOOKED run: deleting them does not un-book the run; use the run correction flow.

Pitfalls:

• Without ?type, ALL absence types in the range are deleted.
• deleted_count: 0 with a 200 means nothing matched: not an error.

GET /api/v1/companies/{companyId}/employees/{id}/opening-balances

Get an employee's payroll cutover opening balances. scope:payroll:read · risk:low · idempotent

Returns the opening balances set for a mid-year migration (YTD gross/tax/net, vacation balances, opening semesterlöneskuld, karens adjustment) plus the lock state: locked=true once the employee has a booked salary run.

Use when: Verifying cutover state before the first calculated run, or checking whether balances can still be edited (locked=false). Do not use for: The live vacation liability (GET /reports/vacation-liability includes the opening terms). Pre-cutover absence history: GET /employees/{id}/absence.

Pitfalls:

• 404 NOT_FOUND when no opening balances have been set: distinct from an all-zeros row.
• locked_by_run_id names the booked run that froze the row; correcting that run unlocks it.

PUT /api/v1/companies/{companyId}/employees/{id}/opening-balances

Set an employee's payroll cutover opening balances. scope:payroll:write · risk:medium · idempotent · dry-run · reversible

Full-replace upsert of the cutover state: YTD gross/tax/net for the cutover year, paid vacation days remaining, paid days already taken this vacation year, sparade dagar keyed by origin year (5-year rule), opening semesterlöneskuld SEK (+avgifter), and karens periods not covered by imported absence rows. cutover_date must be the first of a month in the current or previous year, on/after employment_start.

Use when: Onboarding one employee during a mid-year migration from Fortnox/Visma/etc. For whole-company onboarding, prefer the bulk PUT /employees/opening-balances. Do not use for: SIE opening balances on the LEDGER (2920/2940 arrive via the SIE import). Ongoing sick cases: import pre-cutover days via PUT /employees/{id}/absence instead.

Pitfalls:

• Full replace: omitted numeric fields reset to 0 (their defaults). Send the complete state every time.
• 409 OPENING_BALANCES_LOCKED once the employee has a booked run; correcting that run unlocks.
• The opening liability is NOT booked by Accounted: it only feeds the vacation-liability report.
• YTD affects payslip display and reports only; per-month tax and avgifter caps never read it.

GET /api/v1/companies/{companyId}/employees/{id}/vacation-balance

Get an employee's current vacation balance. scope:payroll:read · risk:low · idempotent

Returns the open vacation-ledger row (recomputed on every booking): entitled/taken/remaining days, sparade dagar keyed by origin year (Semesterlagen 5-year rule), forced-payout days from expired savings, and a computed SEK estimate of the individual semesterlöneskuld.

Use when: Answering "how many vacation days does Anna have left", pre-payroll review, or preparing the year-close. Do not use for: The company-wide liability report: GET /reports/vacation-liability. Closing the year: POST /salary/vacation-year-close.

Pitfalls:

• 404 VACATION_BALANCE_NOT_FOUND until the first booking (or year-close) touches the employee: the ledger seeds lazily.
• remaining_days can go negative if more days were taken than entitled: surface it, do not clamp.
• The SEK estimate uses the year-close day valuation (simplified BFNAR 2016:10); the booked 2920 is reconciled only at year-close.

PUT /api/v1/companies/{companyId}/employees/opening-balances

Bulk-set payroll cutover opening balances (atomic). scope:payroll:write · risk:medium · idempotent · dry-run · reversible

Upserts opening balances for up to 200 employees in one call. Validation is all-or-nothing: any invalid item (unknown/inactive employee, cutover before employment_start, locked by a booked run) fails the WHOLE request with a per-item error list and zero writes.

Use when: Onboarding a whole company mid-year from another payroll system: one call per migration file instead of N sequential PUTs. Do not use for: Single-employee corrections after go-live: PUT /employees/{id}/opening-balances. Ledger opening balances (SIE import).

Pitfalls:

• Atomic: one bad item fails everything. The error details carry item_errors[{index, employee_id, code, message}]: fix and resubmit the full set.
• Full replace per employee: resubmitting with fewer fields resets the omitted ones to 0.
• Duplicate employee_id within items is rejected outright.

POST /api/v1/companies/{companyId}/salary/vacation-year-close

Close a vacation year (semesterberedning + arsavslut). scope:payroll:write · risk:high · idempotent · dry-run

Rolls every active employee's vacation balances into the next year (only days above the 20-day must-take floor are saved; saved days older than 5 years become forced payouts) and reconciles the day-valued semesterlöneskuld against the booked 2920/2940, posting one adjustment verifikation when drift exceeds 1 kr. The frozen report is stored with the closure (BFL 7 kap).

Use when: Once per year after the vacation year ends (Jan for calendar basis, Apr for statutory). ALWAYS dry-run first and review the report: the close is not reversible via API. Do not use for: Mid-year balance corrections (fix the source: absence days, opening balances, or run corrections). Paying out expired days (create a semesterersattning line in the next salary run: the close only flags them).

Pitfalls:

• dry_run=true returns the full review report with zero writes: treat it as mandatory before the live call.
• 409 VACATION_YEAR_ALREADY_CLOSED on replay: the closure row is the idempotency anchor.
• 423-style PERIOD_LOCKED when the adjustment date falls in a locked period: unlock or close without adjustment (book_adjustment=false) and post manually.
• Untaken days at or below the 20-day floor are flagged in the report, NOT auto-saved (Semesterlagen 18 §).
