Copies a task list

Creates a new task list by copying a source task list (template_id) into a target project and folder. By default only the task list shell is copied; enable the copy_* flags to duplicate its tasks and their details.

Required: name, template_id (the source task list), project_id, and the target folder_id.

Copy flags

All copy_* flags default to false. Every flag below requires the "tasks" gate — at least one of copy_open_tasks / copy_closed_tasks.

Enabling any dependent flag without a tasks gate returns 422 (tasks_required).
