Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

Operation: the value that you can use in the Action element to specify the operation on a resource.
Access level: the access level of each operation. The levels are read, write, and list.
Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
- The required resource types are displayed in bold characters.
- If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
Condition Key: the condition key that is defined by the cloud service.
Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

Request parameters

Parameter	Type	Required	Description	Example
StackId	string	Yes	The ID of the stack.	4a6c9851-3b0f-4f5f-b4ca-a14bf691****
ClientToken	string	No	The client token that is used to ensure the idempotence of the request. You can use the client to generate the value, but you must ensure that it is unique among different requests. The value can be up to 64 characters in length and can contain letters, digits, hyphens (-), and underscores (_). For more information, see How to ensure idempotence.	123e4567-e89b-12d3-a456-42665544****
RegionId	string	Yes	The region ID of the stack. You can call the DescribeRegions operation to query the most recent region list.	cn-hangzhou
LogicalResourceId	string	Yes	The name of the resource.	ScalingRuleName
