Lists all the accounts in the organization. To request only the accounts in a specified root or OU, use the ListAccountsForParent operation instead.

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.


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