 ## Plan containers
-In Microsoft Planner, plans are always contained in another resource. The containing resource, [plannerPlanContainer](plannerplancontainer.md), determines the authorization rules of the plan and all the tasks in it, and the lifecycle of the plan. You can create a plan in a container of one of the following types: [driveItem](driveitem.md), Microsoft 365 [group](group.md), Planner project, [roster](plannerroster.md), or [user](user.md).

 Users can upgrade their personal plans into group-based plans by [moving](../api/plannerplan-movetocontainer.md) the plan from the user container to a group container, changing the type of the container for the plan from `user` to `group`. 
 
+### Container type: Teams Channel

+The Teams channel container type supports plans created in Teams shared channels, where the channel is the container for the plan. Plans that are pinned in the shared channels would be deleted when the channel is deleted.
+
+To [create a new plan](../api/planner-post-plans.md) in a Teams channel's container, set the **container** property on a [plan](plannerplan.md) object with **type** being `teamsChannel`, and the id should be formatted at "{team-id}/channels/{channel-id}
