You can use a custom domain name for your content endpoints by adding an alternative domain to the AWS CloudFront distribution used by your project. Once the custom domain is fully setup in CloudFront, you can update your project config in Starsheet so that all URLs generated by Starsheet will use that custom domain name.

When creating a new Starsheet project, it will automatically detect if an alternative domain is already configured on the CloudFront distribution and use that by default.
