Use GetDistributionConfig with an AWS SDK or CLI

To get a CloudFront distribution configuration

The following example gets metadata about the CloudFront distribution with the ID EDFDVBD6EXAMPLE, including its ETag. The distribution ID is returned in the create-distribution and list-distributions commands.

aws cloudfront get-distribution-config --id EDFDVBD6EXAMPLE

Output:
