RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

Request parameters

Parameter	Type	Required	Description	Example
ProjectName	string	Yes	The name of the project. For more information about how to obtain the project name, see Create a project.	test-project
MaxResults	integer	No	The maximum number of datasets to return. Valid values: 0 to 200. If you do not specify this parameter or set it to 0, the default value 100 is used.	1
NextToken	string	No	The pagination token. If the total number of datasets exceeds the value of MaxResults, this token is used for pagination. The list of dataset information is returned in lexicographical order starting from NextToken. Note When you call this operation for the first time in a query, leave this parameter empty.	12345678:immtest:dataset002
Prefix	string	No	The prefix of the dataset name.	dataset

Response elements

Element	Type	Description	Example
	object	The response struct.
Datasets	array	The list of dataset information.
	Dataset	The dataset. Note The ListDatasets operation does not support file statistics. The values of the FileCount and TotalFileSize fields in the returned Dataset struct may be inaccurate or 0. To obtain accurate file statistics, use GetDataset - Query statistics information.
NextToken	string	The pagination token. If the total number of datasets exceeds the value of MaxResults, this token is used for pagination. This parameter is returned only when not all matching datasets are returned. Pass this value as NextToken in the next request to return the remaining datasets.	12345678:immtest:dataset002
RequestId	string	The request ID.	FEEDE356-C928-4A36-951A-6EB5A592****
