Private API Gateway in separate regions

Question

How can I use Private API Gateway in my account to allow clients in other region accounts to connect from VPC endpoints? If impossible can I define both public and private (low latency) API gateways so that clients in other regions can join from the public API gateway connected to the same resources and lambda resolver?

Answer

It is possible to create both public and private API Gateways to allow clients in other AWS accounts or regions to connect.

You can define a private API Gateway accessible within a VPC via a VPC endpoint. This allows low latency access for clients located within the same VPC.

A public API Gateway can be set up with an edge-optimized custom domain. This allows clients outside the VPC, including those in other AWS accounts or regions, to access the APIs over the public internet.

The public and private API Gateways can be configured to point to the same backend Lambda function or application. This allows clients on both the public and private networks uniform access to the APIs and resources.
