[Midas] Fwd: Midas Contact

What you're seeing is an empty zip file when trying to download the item.
 That's because the permission check failed, which is actually a bug on our
side because we are redirecting to a new controller that doesn't know about
the api auth mechanism.

As a workaround, is your client able to handle cookies?  If so, you could
use session-based authentication instead of the token.  If the client
you're writing is javascript that lives on the same server, you can simply
pass the "useSession" parameter instead of the token, and javascript
automatically passes the appropriate cookie.  Java applets do the same
thing.  If your client is something else, you could store and pass the
cookie manually.

I will work on fixing this bug for now.  Thanks for the report.
