Amazon API Gateway simplifies accessing private APIs by allowing you to associate one or more Amazon Virtual Private Cloud (VPC) Endpoints to a private API. API Gateway will create and manage DNS alias records necessary for easily invoking the private APIs. With this feature, you can leverage private APIs in web applications hosted within your VPCs.  

Private APIs enable you to securely expose REST APIs to resources only within your VPCs via VPC Endpoints (VPCE). You define Resource Policies in API Gateway along with VPC Endpoint policies to control access between VPCs and private APIs.  

When you want to disable private Domain Name System (DNS) on the VPCE and allow access to a private API via this VPCE, you can use this feature to get an endpoint alias for your private API. 

You can use this feature in in Amazon Web Services China (Beijing) Region, operated by Sinnet and Amazon Web Services China (Ningxia) Region, operated by NWCD.
