i dont want to use a fully custom domain, just prefer to name something like "my-api-thingy.execute-api.us-east-1.amazonaws.com"

Hey Ernie - this isn't possible because aws auto assigns these unlike s3 buckets afaik

no problem, thanks for your help.

or ask AWS to sell the

<http://amazonaws.com|amazonaws.com>

domain to u 🚀
