Private integration using VPC links V1 (legacy)

To create a private integration, you must first create a Network Load Balancer. Your Network Load Balancer must have a listener that routes requests to resources in your VPC. To improve the availability of your API, ensure that your Network Load Balancer routes traffic to resources in more than one Availability Zone in the AWS Region. Then, you create a VPC link that you use to connect your API and your Network Load Balancer. After you create a VPC link, you create private integrations to route traffic from your API to resources in your VPC through your VPC link and Network Load Balancer. The Network Load Balancer and API must be owned by the same AWS account.
