AWS ApiGateway VPC Link vs HTTP Proxy integration

Question

Well, I'm creating a AWS ApiGateway and I can't understand when I should use integration type HTTP_PROXY or VPC_LINK, both ask me URL to proxy.

I searched about it but can't found any concrect and simple example, when use one or other ?

Answer 1

API Gateway REST API allows proxy integrations to other endpoints via two methods.

• HTTP_PROXY is for Public API endpoints only.

• VPC_LINK allows us to integrate API Gateway with Private Endpoints exposed via NLB (not ALB)

API Gateway HTTP API also supports both public and private integrations

• HTTP URI: For public endpoints.
• Private Resource: For NLB, ALB or CloudMap

Answer 2

I'm setting up an HTTP AWS API Gateway with Lambda integrations. But I'm running into the issue Lambda integration requires integration_type = AWX_PROXY But it’s incompatible with connection_type = "VPC_LINK" which requires integration_type = "HTTP_PROXY". I can change to connection_type = "INTERNET" to make these compatible. But is this the only way?
