Access public apigateway API via VPC endpoint

Question

Is it possible to connect a private (within vpc) lambda to a public api via vpc endpoint ?

Currently I am getting 403 forbidden error. 
I understand that by disabling private DNS option of vpc endpoint 
I can make lambda go through internet and connect to the public api. 
But I want to pass the traffic through the vpc endpoint without going to the internet.

Any comments would be appreciated.
Thanks

Hi,

Have you checked this knowledge center article: https://aws.amazon.com/premiumsupport/knowledge-center/api-gateway-vpc-connections/

Answer

Just to clarify one point: Traffic between your VPC and public services in AWS does not traverse the internet. Yes, there are public IP addresses involved but all traffic stays on the Amazon backbone network. Using public IP addressing does not mean that traffic is over the public Internet.

This is stated in the VPC FAQ - look for "Does traffic go over the internet".

This is stated in the [VPC FAQ](https://aws.amazon.com/vpc/faqs/) - look for "Does traffic go over the internet".
