Create a task

​

Creates a task. Only title is required — a task does not need a project, an assignee or a date.

Assign the task with assignee_member_id: a team member id from GET /public-api/v1/team_members, or me for whoever the token belongs to. Responses report the assignee twice, as assignee_member_id and as the user's assignee_id, but only assignee_member_id is writable.

Subtasks

Send parent_task_uuid to create the task underneath an existing one. A subtask takes its project and billable setting from its parent, so project_id cannot be sent alongside parent_task_uuid.

Tasks nest two levels deep at most — a top-level task, a subtask, and a subtask of that. Pointing at a parent that is already at the bottom fails with 422 invalid_value. Read a task's children with GET /public-api/v1/tasks/{uuid}/subtasks.
