Request parameters

Parameter	Type	Required	Description	Example
ProjectName	string	Yes	The name of the project. For more information, see CreateProject .	test-project
MaxResults	long	No	The maximum number of datasets to return. Valid values: 0 to 200. If this parameter is left empty or set to 0, 100 datasets are returned.	1
NextToken	string	No	The pagination token. If the total number of datasets is greater than the value of MaxResults, you must specify this parameter.
