How to create a Dropbox app using for Attachment Type

I have tried to create a Dropbox App using for the attachment type but don’t know what the Redirect URIs that I have to add to the Dropbox app. Please kindly advise.

I see this is a bit old, but since I’m going through some things with Dropbox and Epicor, I will post a response for folks who may be struggling.

The easy way I found the correct redirect URL was to try and use the newly created app inside Epicor. An error popped up regarding the redirect URL and you can copy/paste that into your Dropbox app setup. Sounds like a backwards way of doing it, but it worked.
