Copy a New File Automatically from Amazon S3 Bucket to a Box InBox Folder that Syncs Locally

When a new file is uploaded to a bucket in Amazon S3, we will create a routine that automatically copies the file to a Box Folder that will serve as an In box.   I believe we are going to use Python to code this.

Any advice or help on this would be appreciated before we start trying to do this.  Is there any easy interface to box for the API to upload to the same folder each time?  Anything I should do to prepare?

Thank you.
