Global Accelerator:CreateEndpointGroup

Last Updated:Oct 13, 2026

Creates an endpoint group.

Operation description

  • When you call this operation to create a virtual endpoint group for a Layer 4 listener, make sure that a default endpoint group is created.

  • CreateEndpointGroup is an asynchronous operation. After you call this operation, the system returns an endpoint group ID, but the endpoint group is not yet created and the creation task is still running in the background. You can call DescribeEndpointGroup to query the status of the endpoint group:

    • When the endpoint group is in the init state, the endpoint group is being created. In this state, you can only perform query operations.

    • When the endpoint group is in the active state, the endpoint group is created.

  • You cannot call the CreateEndpointGroup operation to concurrently create endpoint groups for the same Global Accelerator (GA) instance.

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.
