harvest_list_time_entriesList time entries, optionally filtered by user, project, client, task, date range, running/billed status, or updated-since. Paginated. Harvest REST: GET /time_entries.harvest_get_time_entryRetrieve a single time entry by id. Harvest REST: GET /time_entries/{id}.harvest_list_projectsList projects, optionally filtered by active status or client, or updated-since. Paginated. Harvest REST: GET /projects.harvest_get_projectRetrieve a single project by id. Harvest REST: GET /projects/{id}.harvest_list_clientsList clients, optionally filtered by active status or updated-since. Paginated. Harvest REST: GET /clients.harvest_get_clientRetrieve a single client by id. Harvest REST: GET /clients/{id}.harvest_list_tasksList tasks (the billable/non-billable work categories that can be assigned to projects), optionally filtered by active status or updated-since. Paginated. Harvest REST: GET /tasks.harvest_list_usersList users in the account, optionally filtered by active status or updated-since. Paginated. Harvest REST: GET /users.harvest_get_current_userRetrieve the currently authenticated user (whom the access token belongs to). Harvest REST: GET /users/me.harvest_list_project_assignmentsList the authenticated user's active project assignments — the projects and their assignable tasks the current user can log time against (use this to find the project_id + task_id for harvest_create_time_entry). Paginated. Harvest REST: GET /users/me/project_assignments.harvest_list_invoicesList invoices, optionally filtered by client, project, state, date range, or updated-since. Paginated.

Harvest REST: GET /company.harvest_create_time_entryCreate a time entry. Requires project_id, task_id and spent_date. Provide `hours` to log a specific duration; OR provide `started_time` (+ optional `ended_time`) for a timestamped entry; OR omit both to start a running timer (on a timestamp-tracking account). Use harvest_list_project_assignments toharvest_update_time_entryUpdate an existing time entry's hours, notes, spent date, or project/task. Only the fields you provide are changed. Harvest REST: PATCH /time_entries/{id}. WRITE — modifies data.harvest_stop_time_entryStop a currently running time entry (no-op error if it is already stopped). Harvest REST: PATCH /time_entries/{id}/stop. WRITE — modifies data.harvest_restart_time_entryRestart a previously stopped time entry, resuming its timer (error if it is already running). Harvest REST: PATCH /time_entries/{id}/restart. WRITE — modifies data.harvest_delete_time_entryPermanently delete a time entry by id. This cannot be undone. Harvest REST: DELETE /time_entries/{id}. WRITE — destroys data.
