#Task checklist

Task checklist items — a nested resource of a task. Each item has a title, a completion status, an importance flag, a sort order, members, and (optionally) a parent item for nested checklists. Base path — /v1/tasks/:taskId/checklist. All operations require an existing task (:taskId) on the portal.

Bitrix24 API: task.checklistitem.* Scope: task

Why a separate resource. Bitrix24 does not accept the CHECKLIST field inside POST /v1/tasks (tasks.task.add) — a checklist cannot be created together with the task. The only supported way to manage items is the task.checklistitem.* family of methods, which this resource wraps. First create the task, then add items one by one.
