# GET /#Action=DetachTrafficSources

`GET /#Action=DetachTrafficSources`

Detaches one or more traffic sources from the specified Auto Scaling group.

When you detach a taffic, it enters the `Removing` state while deregistering the instances in the group. When all instances are deregistered, then you can no longer describe the traffic source using the DescribeTrafficSources API call. The instances continue to run.

## Query parameters

- `AutoScalingGroupName` string, required
- `TrafficSources` TrafficSourceIdentifier[], required
  - `Identifier` string, required — <p>Identifies the traffic source.</p> <p>For Application Load Balancers, Gateway Load Balancers, Network Load Balancers, and VPC Lattice, this will be the Amazon Resource Name (ARN) for a target group in this account and Region. For Classic Load Balancers, this will be the name of the Classic Load Balancer in this account and Region.</p> <p>For example: </p> <ul> <li> <p>Application Load Balancer ARN: <code>arn:aws:elasticloadbalancing:us-west-2:123456789012:targetgroup/my-targets/1234567890123456</code> </p> </li> <li> <p>Classic Load Balancer name: <code>my-classic-load-balancer</code> </p> </li> <li> <p>VPC Lattice ARN: <code>arn:aws:vpc-lattice:us-west-2:123456789012:targetgroup/tg-1234567890123456</code> </p> </li> </ul> <p>To get the ARN of a target group for a Application Load Balancer, Gateway Load Balancer, or Network Load Balancer, or the name of a Classic Load Balancer, use the Elastic Load Balancing <a href="https://docs.aws.amazon.com/elasticloadbalancing/latest/APIReference/API_DescribeTargetGroups.html">DescribeTargetGroups</a> and <a href="https://docs.aws.amazon.com/elasticloadbalancing/latest/APIReference/API_DescribeLoadBalancers.html">DescribeLoadBalancers</a> API operations.</p> <p>To get the ARN of a target group for VPC Lattice, use the VPC Lattice <a href="https://docs.aws.amazon.com/vpc-lattice/latest/APIReference/API_GetTargetGroup.html">GetTargetGroup</a> API operation.</p>
  - `Type` string — <p>Provides additional context for the value of <code>Identifier</code>.</p> <p>The following lists the valid values:</p> <ul> <li> <p> <code>elb</code> if <code>Identifier</code> is the name of a Classic Load Balancer.</p> </li> <li> <p> <code>elbv2</code> if <code>Identifier</code> is the ARN of an Application Load Balancer, Gateway Load Balancer, or Network Load Balancer target group.</p> </li> <li> <p> <code>vpc-lattice</code> if <code>Identifier</code> is the ARN of a VPC Lattice target group.</p> </li> </ul> <p>Required if the identifier is the name of a Classic Load Balancer.</p>
- `Action` 'DetachTrafficSources', required
- `Version` '2011-01-01', required
