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
ListenerId	string	Yes	The listener ID.	lsn-bp1bpn0kn908w4nbw****@80
DryRun	boolean	No	Specifies whether to perform a dry run without sending the request. Valid values: true: performs only a dry run. The system checks the request for potential issues, including missing parameter values, incorrect request syntax, and service limits. If the request fails the dry run, an error message is returned. If the request passes the dry run, the `DryRunOperation` error code is returned. false (default): performs a dry run and sends the request. If the request passes the dry run, a 2xx HTTP status code is returned and the operation is performed.	false
ClientToken	string	No	The client token used to ensure the idempotence of the request. You can use the client to generate the token. The token must be unique across requests and can contain only ASCII characters. Note If you do not specify this parameter, the system uses the request ID as the client token. Each request ID is unique.	123e4567-e89b-12d3-a456-426655440000
RegionId	string	No	The region ID of the NLB instance. Call the DescribeRegions operation to query available regions.	cn-hangzhou
