  title: Microsoft Planner Microsoft Graph Planner Buckets Plans API
  description: The Microsoft Graph Planner API enables programmatic access to Planner resources in Microsoft 365. You can create and manage plans, tasks, and buckets to organize work, assign tasks to users, and track progress within groups. Plans are contained by Microsoft 365 groups, and tasks are organized into buckets within plans. This API covers the v1.0 stable endpoint for basic (non-premium) Planner operations.
