2025-07-11

2024-06-28

• Added new endpoints to support the activity management module:
• /todos — manage tasks and assignments
• /todo-lists — organize tasks into structured lists

2024-01-09

• Added automatic calculation of time_total when creating a Time Entry, if not explicitly provided, using time_start and time_end values when available.
• Improved handling of time_start, time_end, and time_total fields in Time Entries to ensure consistent and predictable results. When only some time fields are provided, the API now automatically fills in the others — prioritizing total time first, then start time, and finally end time. This change prevents mismatched durations and ensures accurate total hours are always recorded, even when partial data is sent in requests.

• Initial release of the Rabbiit API documentation, launched in closed beta for selected customers.
• Introduced core endpoints for time tracking, users, projects, and customers.
