We have a lot of sensitive information for various clients in our DropBox account. We would like to know who has shared access to our files. Can some type of option be provided so that will allow us to see who files are shared with.
You can see who is in shared folders at www.dropbox.com/share but no other info is available
If you call https://www.dropbox.com/developers/core/docs#metadata with the include_membership query parameter, you'll get a list of all the members of the shared folder.
include_membership
https://www.dropbox.com/developers/core/docs#shared-folders will return a list of all shared folders and the membership of each.
Shared folder metadata just came out of beta: https://www.dropbox.com/developers/blog/119/shared-folder-metadata-now-in-production.
