I am trying to create an app which a user can upload a file from their box account. It looks like this is possible but I can't seem to find the correct tools (or combination of tools).
I would like:
1. Have user sign in. I'm assuming this would be something like "[My App] want's to access your files, sign in.. ".
2. Once the user signs in, use that access token (or obtain token with some access code), to give them a nice Box Content Picker of THEIR files, so they can upload one.
What would be the correct API/SDK/UI tools to do this?
