Connect PowerQuery to S3 Compatible Data Source

Hi,

I would like to connect excel files to data sources which are S3 Compatible much in the same way one might use "S3 Browser" or "Cyberduck". I would like to use PowerQuery & PowerPivot to create advanced Data Visualizations and have Cloud based data sources that are S3 Compatible so I have a REST Endpoint and the necessary Keys for connection. Thanks, Jeff
