问题
I am trying to make a integration between API Gateway API and a resource behind VPC.
While creating the integration, there is a option to select, "Use Proxy Integration". Even if I am not selecting this check box and deploy the API, I am able to make the API Gateway connectivity working via NLB to the target resource behing VPC.
So, I am having difficulty in understanding still why we need to select the check box.
