How to allow a Lambda that is inside a private VPC to make a GET request to a Regional API in API Gateway

Question

I have a lambda that needs to be inside a private subnet in the VPC so that it can connect to a Neptune database, but by doing it I can't make a GET request from a Regional API from my API gateway, from the research I made it seems like I need to set a NAT Gateway to connect to a public subnet in order to be able to make the GET request that I need to do.

I'm asking this question to make sure that what I need to do is set up a NAT Gateway, and if so what would be the best way to do that, [is this a good guide on how to do it?](https://www.datanextsolutions.com/blog/using-nat-gateways-in-aws/)

If setting up a NAT Gateway isn't the best way to resolve my issues, what would be?

Thanks in advance

If you want to grant internet access to your AWS Lambda function in a VPC *(private subnet)*, set up a NAT gateway. Here is a great [step-by-step guide](https://repost.aws/knowledge-center/internet-access-lambda-function).

HI, tomsantos. To avoid problems with missing something important please use official documentation about how to setup a nat gateway like https://docs.aws.amazon.com/vpc/latest/userguide/vpc-nat-gateway.html. Also please use this documentation https://docs.aws.amazon.com/lambda/latest/dg/services-apigateway.html to correctly setup lambda with API gateway.
