Create Timesheet Entry
Create a new time entry. Two ways to log time, matching the account's Company setting: on duration-based accounts (wantstimestamptimers is false — the common case) set Hours to log a completed entry directly. On timestamp-based accounts (wantstimestamptimers is true) leave Hours blank and use Started Time/Ended Time instead — leave both time fields blank too to start a running timer now, or set both to log a completed entry with explicit start/end times. Passing Started/Ended Time on a duration-based account is silently ignored by Harvest (it starts a running timer instead) — if that happens, switch to Hours. Use Get Projects to find a Project ID, List Tasks to find a Task ID, and List Users to find a User ID. Example (duration-based): call with projectId, taskId, spentDate=\"2026-09-17\", hours=3.5. Example (timestamp-based): the same call with hours omitted and startedTime/endedTime set instead. and start/end time variant.

Harvest integration FAQ
Yes. Harvest is one of the 9,800+ tools Viktor connects to, in one click via OAuth. Once connected, anyone on your team can put Viktor to work in Harvest from their workspace - no workflow builder, no code.
Ask Viktor in your workspace to connect Harvest, then approve the one-click OAuth prompt. Viktor never sees your password, handles authentication itself, and starts working right away. Setup takes about two minutes, and you can revoke access at any time.
Viktor can run 37 Harvest actions, including Get Me, Get User, and List Tasks - and chain them with other tools in a single request. In practice that means Viktor helps you track billable hours and timesheets. If a task spans several actions, Viktor plans the sequence itself and reports back when the work is done.
No. Viktor isn't a workflow builder - there are no triggers to map and nothing to maintain. You ask for the outcome in plain English in your workspace, and Viktor decides which Harvest actions to take, runs them, and reports back.
