Server Load Balancer:AssociateAdditionalCertificatesWithListener

Last Updated:Aug 28, 2026

Associates additional certificates with a listener that uses SSL over TCP.

Operation description

AssociateAdditionalCertificatesWithListener is an asynchronous operation. After you send a request, the system returns a request ID and runs the task in the background. You can call the ListListenerCertificates operation to query the status of the task:

  • If the listener is in the Associating state, the additional certificates are being associated.

  • If the listener is in the Associated state, the additional certificates are associated.

Test

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.

Description

Example

AdditionalCertificateIds

DryRun

boolean

No

Whether to perform a dry run. Valid values:

  • true: validates the request without performing the operation. The system checks for potential issues, including missing parameter values, incorrect request syntax, and service limits. If the request fails validation, the corresponding error message is returned. If the request passes validation, the DryRunOperation error code is returned.

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

true

ClientToken

string

No

The client token that ensures the idempotence of the request.

You can use the client to generate the token. The token must be unique among different requests and contain only ASCII characters.

Note

If you do not set this parameter, the value of RequestId is used. The value of RequestId is different for each request.
