Detaches Classic Load Balancer (CLB, formerly known as Server Load Balancer or SLB) instances from a scaling group. If the current CLB instance no longer meets your business requirements, you can call the DetachLoadBalancers operation to detach it from your scaling group. When you call this operation, you can use ScalingGroupId, LoadBalancer.N, and ForceDetach to specify one or more CLB instances to detach. You can also determine whether to call this operation asynchronously and whether to remove the Elastic Compute Service (ECS) instances acting as backend servers from the backend server groups of the CLB instance. You can call this operation to detach only CLB instances from a scaling group.

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 Resourcesis 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
| Parameter | Type | Required | Description | Example |
|---|---|---|---|---|
| ScalingGroupId | string | Yes | The ID of the scaling group. | asg-bp1ffogfdauy0jw0**** |
| ForceDetach | boolean | No | Specifies whether to remove Elastic Compute Service (ECS) instances in the scaling group from the backend server groups of the Server Load Balancer (SLB) instance. Valid values:
Default value: false. | 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 value, but you must ensure that the value is unique among different requests. The token can contain only ASCII characters and cannot exceed 64 characters in length. For more information, see How to ensure idempotence. | 123e4567-e89b-12d3-a456-42665544**** |
| Async | boolean | No | Specifies whether to detach the CLB instance from the scaling group in an asynchronous manner. If you detach the CLB instance from the scaling group in an asynchronous manner, the call is successful only after all operations are successful. If a specific operation fails, the call fails. We recommend that you set this parameter to true. Valid values:
Default value: false. | false |
| LoadBalancers | array | Yes | The IDs of the CLB instances. You can specify up to five instance IDs. | |
| string | Yes | The IDs of the CLB instances. You can specify up to five instance IDs. | lb-2zeur05gfs**** | |
| RegionId | string | No | The region ID of the scaling group. | cn-qingdao |
