  title: Amazon EC2 Auto Scaling Register Lifecycle Hook and Complete Action
  summary: Add a lifecycle hook to a group, confirm it, and complete a pending lifecycle action.
  description: >-
    Sets up an instance lifecycle hook and resolves a wait-state action. The
    workflow puts a lifecycle hook on the group, describes the group's lifecycle
    hooks to confirm registration and capture the hook details, and then
    completes a pending lifecycle action for a specific instance with the
    supplied result so the instance can proceed through its lifecycle. Every
    step spells out the AWS query-protocol Action and Version inline so the flow
    can be read and executed without opening the underlying OpenAPI description.
