Agent pitfalls & tips
- Date format: YYYY-MM-DD. All times are in JST (UTC+9).
- Overtime is in minutes, not hours. 60 = 1 hour overtime.
- Read-only API in most plans. Write operations (clock in/out) require premium API access.
- Employee IDs are company-specific codes, not universal IDs. Get the mapping from GET /employees.
- Japanese labor law compliance: 36協定 (Article 36 agreement) limits apply. overtime_minutes reflects legal overtime.
