AWS API gateway domain mapping

I have domain with aws example.com, currently I have record set so that when user goes to example.com, it serves static website from S3 (done with angular). Now, I have backend api (Lambda and API gate way), which is has url something like,

https://randomid.execute-api.region.amazonaws.com/Prod/api/getSomething?id=1

so, what I am trying to do is if front end makes a http call to example.com /api/getSomething?id=1, it should return me data (since I am using relative urls).

I was reading aws documentation, it seems i cannot use root domain, I have to use subdomain (api.example.com), I am ok with it. But, I am not sure how can i do that, any help would be appreciated.

Also, I may move my front end to subdomain (web.example.com), if I do that, with my backend at (api.example.com, hope fully I will figure this part), will I run into CORS issue?

Go through this AWS developer guide to change the domain name.

Apart from DNS configurations, it also requires to have a SSL certificate for the custom domain (Which could be taken from AWS Certificate Manager for free).

Also note that an API's custom domain name can be the name of a subdomain or the root domain (aka, zone apex) of a registered Internet domain.

If your Web and API have different subdomains, it will run into CORS. However you can setup a CloudFront distribution infront of both Web and API to avoid CORS.
