# POST /#Action=DetachLoadBalancers

`POST /#Action=DetachLoadBalancers`

<note> <p>This API operation is superseded by <a>DetachTrafficSources</a>, which can detach multiple traffic sources types. We recommend using <code>DetachTrafficSources</code> to simplify how you manage traffic sources. However, we continue to support <code>DetachLoadBalancers</code>. You can use both the original <code>DetachLoadBalancers</code> API operation and <code>DetachTrafficSources</code> on the same Auto Scaling group.</p> </note> <p>Detaches one or more Classic Load Balancers from the specified Auto Scaling group.</p> <p>This operation detaches only Classic Load Balancers. If you have Application Load Balancers, Network Load Balancers, or Gateway Load Balancers, use the <a>DetachLoadBalancerTargetGroups</a> API instead.</p> <p>When you detach a load balancer, it enters the <code>Removing</code> state while deregistering the instances in the group. When all instances are deregistered, then you can no longer describe the load balancer using the <a>DescribeLoadBalancers</a> API call. The instances remain running.</p>
