Server Load Balancer:LoadBalancerLeaveSecurityGroup

Last Updated:Jul 17, 2025

Removes an Application Load Balancer (ALB) instance from a security group.

Operation description

  • LoadBalancerLeaveSecurityGroup is an asynchronous operation. After a request is sent, the system returns a request ID and runs the task in the background. You can call the ListAsynJobs operation to query the status of the task.

    • If the task is in the Succeeded state, the ALB instance is removed from the security group.
    • If the task is in the Processing state, the ALB instance is being removed from the security group. In this case, you can query the task but cannot perform other operations.

Debugging

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.
