Answer 1

In your API Gateway OPTIONS method, go into Method Response and add a response header with the name 'Access-Control-Allow-Origin'.

Now go into Integration Response, expand the default 200 response and in Header Mappings put the URL of your DNS. If you don't want to restrict by URL, just put a *.

You may need to add this configuration to other methods as well.
