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
Marker	string	No	The pagination token that is used in the next request to retrieve a new page of results. You do not need to specify this parameter for the first request.`` When you call the operation for the first time, if the total number of returned entries exceeds the value of `MaxItems`, the entries are truncated. The system returns entries based on the value of `MaxItems` and does not return the excess entries. In this case, the value of the response parameter `IsTruncated` is `true`, and `Marker` is returned. In the next call, you can use the value of `Marker` and maintain the settings of the other request parameters to query the excess entries. You can repeat the call until the value of the `IsTruncated` parameter becomes `false`. This way, all entries are returned.	EXAMPLE
MaxItems	integer	No	The number of entries per page. Valid values: 1 to 100. Default value: 100.	100
