You can now use Amazon Route 53 alias records to map custom domain names (such as api.example.com) both to API Gateway custom regional APIs and edge-optimized APIs and to Amazon VPC interface endpoints, without incurring additional Route 53 query charges. Alias records also let you point your zone apex (such as example.com) at these resources, which is not possible using standard DNS CNAME records.
You can create alias records pointing to API Gateway resources and Amazon VPC endpoints using the Route 53 console or API. To learn more, see the Amazon Route 53 developer guide.
