    Global Accelerator:UpdateEndpointGroups

    Last Updated:Sep 09, 2024

    Modifies the endpoint groups that are associated with a listener.

    Operation description

    Description

    • UpdateEndpointGroups is an asynchronous operation. After a request is sent, the system returns a request ID and runs the task in the background. You can call the DescribeEndpointGroup or ListEndpointGroups operation to query the status of an endpoint group.

      • If the endpoint group is in the updating state, it indicates that the configuration of the endpoint group is being modified. In this case, you can perform only query operations.
      • If the endpoint group is in the active state, it indicates that the configuration of the endpoint group is modified.

    • The UpdateEndpointGroups operation holds an exclusive lock on the Global Accelerator (GA) instance. While the operation is in progress, you cannot call the same operation in the same Alibaba Cloud account.

    Debugging

    OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.

    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

    ParameterTypeRequiredDescriptionExample
    RegionIdstringYes

    The region ID of the GA instance. Set the value to cn-hangzhou.

    		cn-hangzhou
    ClientTokenstringNo

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

    You can use the client to generate the token, but you must make sure that the token is unique among different requests. The client token can contain only ASCII characters.

    Note If you do not specify this parameter, the system automatically uses the request ID as the client token. The request ID may be different for each request.

    DryRunbooleanNo

    Specifies whether to perform only a dry run, without performing the actual 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 performs the actual request. If the request passes the dry run, a 2xx HTTP status code is returned and the operation is performed.
