    Server Load Balancer：UpdateListenerAttribute

    更新时间：Dec 10, 2025

    Updates the attributes of a listener, such as the listener name and default actions.

    Operation description

    UpdateListenerAttribute is an asynchronous operation. After you send a request, the system returns a request ID and runs the task in the background. The listener configuration is not updated immediately. You can call the GetListenerAttribute operation to query the update status of the listener:

    • If a listener is in the Configuring state, it is being updated.

    • If a listener is in the Running state, it has been updated.

    Try it now

    Try this API in OpenAPI Explorer, no manual signing needed. Successful calls auto-generate SDK code matching your parameters. Download it with built-in credential security for local usage.

    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.

    Parameter

    Type

    Required

    Description

    Example

    ListenerId

    string

    Yes

    The ID of the Application Load Balancer (ALB) listener.

    lsn-123456

    ClientToken

    string

    No

    The client token that is used to ensure the idempotence of the request.

    The token must be unique among requests and can contain only ASCII characters.

    DryRun

    boolean

    No

    Specifies whether to perform a dry run. Valid values:

    • true: performs a dry run. The system checks the required parameters, request format, and service limits. If the request fails the dry run, an error message is returned. If the request passes the dry run, the system returns the DryRunOperation error code.

    • false (default): performs a normal request. If the request passes the check, the system returns a 2xx HTTP status code and performs the operation.

    true

    ListenerDescription

    string
