title: AWS API Gateway to External REST API
body: <p>Is it possible to connect a AWS API Gateway REST API to an external API? I guess the answer is yes since I was able to do this to a simple flask endpoint through an public IP on an EC2 instance. However, when I try to do this to an external public API endpoint I cannot figure out how to send the API Key for the remote API. The documentation really does not talk about this use case. Searching the web also did not provide any answers. </p>
