Custom domain for API Gateway returning 403 : <p>I am creating an api using API Gateway and Lambda. Using the url designated in the API Gateway Stage editor everything works fine; however, when I try and move to a custom domain I am running into some issues. </p>

<p>The first thing I tried was using a CNAME record in Route 53 straight from my domain onto the domain that I got from the API Gateway. That was returning some errors and I think it is the incorrect solution is that correct?</p>

<p>Next I tried the Custom Domain Names feature in API Gateway. My understanding is this will roll up a CloudFront distribution that I can then map onto from Route 53. When I created the custom domain and added a Domain Mapping it provides me with a url to what I assume is a CloudFront distribution. The link is returning a 403 response and no distribution has been made in CloudFront. What is a good way of debugging this problem?</p>
