AWS SDK Version 3 for .NET
API Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

Lists the roots that are defined in the current organization.

Always check the NextToken response parameter for a null value when calling a List* operation. These operations can occasionally return an empty set of results even when there are more results available. The NextToken response parameter value is nullonly when there are no more results to display.

This operation can be called only from the organization's master account.

Policy types can be enabled and disabled in roots. This is distinct from whether they are available in the organization. When you enable all features, you make policy types available for use in that organization. Individual policy types can then be enabled and disabled in a root. To see the availability of a policy type in an organization, use DescribeOrganization.


For .NET Core and PCL this operation is only available in asynchronous form. Please refer to ListRootsAsync.
