# DetachLoadBalancerTargetGroups
<a name="API_DetachLoadBalancerTargetGroups"></a>

**Note**  
This API operation is superseded by [DetachTrafficSources](https://docs.aws.amazon.com/autoscaling/ec2/APIReference/API_DetachTrafficSources.html), which can detach multiple traffic sources types. We recommend using `DetachTrafficSources` to simplify how you manage traffic sources. However, we continue to support `DetachLoadBalancerTargetGroups`. You can use both the original `DetachLoadBalancerTargetGroups` API operation and `DetachTrafficSources` on the same Auto Scaling group.

Detaches one or more target groups from the specified Auto Scaling group.

When you detach a target group, it enters the `Removing` state while deregistering the instances in the group. When all instances are deregistered, then you can no longer describe the target group using the [DescribeLoadBalancerTargetGroups](https://docs.aws.amazon.com/autoscaling/ec2/APIReference/API_DescribeLoadBalancerTargetGroups.html) API call. The instances remain running.

**Note**  
You can use this operation to detach target groups that were attached by using [AttachLoadBalancerTargetGroups](https://docs.aws.amazon.com/autoscaling/ec2/APIReference/API_AttachLoadBalancerTargetGroups.html), but not for target groups that were attached by using [AttachTrafficSources](https://docs.aws.amazon.com/autoscaling/ec2/APIReference/API_AttachTrafficSources.html).
