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.

string

Yes

The listener ID.

lsn-bp1bpn0kn908w4nbw****@80

DryRun

boolean

No

Specifies whether to perform a dry run. Valid values:

  • true: checks the request without performing the operation. The system validates parameter values, request syntax, and service limits. If the check fails, an error message is returned. If it passes, the DryRunOperation error code is returned.

  • false (default): sends the request. If validation passes, a 2xx HTTP status code is returned and the operation is performed.

false

ClientToken

string

No

The client token that is 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. The request ID is different for each request.
