How can I get list of files and file versions in a folder of s3 bucket using API?

Hi,

You could consider using AWS SDK for this use case as it would simplify your programming experience. There are few examples in the articles below which will help you understand how to list the S3 objects and its versions using the AWS SDK.

Thanks

Here is how you do this in the AWS CLI:

aws s3api list-object-versions \
    --bucket _YOUR_BUCKET_NAME_ \
    --prefix _YOUR_FOLDER_NAME_ \
    --query Versions[*].[Key,VersionId]
