Hey Peter, minor fix: the redirect URL should end in .cls of course.

Also, I am trying this out and found yours and Eduard's how-tos very clear. However I am seeing permissions issues despite having checked every option in my Dropbox account. The error I am getting is this (on file retrieval)

ERROR #8921: Error response: ERROR 401: {"error_summary": "missing_scope/..", "error": {".tag": "missing_scope", "required_scope": "files.metadata.read"}}.

I created a Dropbox folder called ToIRIS and have the MFT source folder set to /ToIRIS.

I think I am missing a step. Any ideas?

Thx!

FYI but Cedric is dealing I believe with a Business Service. So his only option roght now is to mod the library code
