Checklists

The Checklists API manages checklist items that belong to a parent resource (for example a task or a project), plus their status, ordering and comments.

New to the API? Start with Getting started (base URL, response envelope, errors, pagination) and Authentication (API keys). Those conventions apply to every endpoint below and are not repeated here.

Identifier note: checklist items are addressed by their numeric checklist_id. Each item belongs to a parent identified by checklistresource_type + checklistresource_id (e.g. task / 123). Listing is always scoped to a parent.
