Permissions

Choose the permission or permissions marked as least privileged for this API. Use a higher privileged permission or permissions only if your app requires it. For details about delegated and application permissions, see Permission types. To learn more about these permissions, see the permissions reference.

This API supports admin permissions. Users with the Global Administrator or Microsoft Teams service admin roles can access teams that they aren't a member of.

Permission type Least privileged permissions Higher privileged permissions
Delegated (work or school account) Channel.ReadBasic.All ChannelSettings.Read.All, ChannelSettings.ReadWrite.All, Directory.Read.All, Directory.ReadWrite.All, Group.Read.All, Group.ReadWrite.All
Delegated (personal Microsoft account) Not supported. Not supported.

Note

  • The ChannelSettings.Read.Group and ChannelSettings.ReadWrite.Group permissions use resource-specific consent.
  • The Group.Read.All, Group.ReadWrite.All, Directory.Read.All, and Directory.ReadWrite.All permissions are supported only for backward compatibility. We recommend that you update your solutions to use an alternative permission listed in the previous table and avoid using these permissions going forward.

HTTP request

GET /teams/{team-id}/channels

Optional query parameters

This method supports the $filter and $select OData query parameters to help customize the response.

Use $select for better performance

Populating the email property for a channel is an expensive operation that results in slow performance. Use $select to exclude the email property to improve performance.

Note: This API does not return the moderationSettings property for a channel by default. To get this property, use the $select query parameter.
