Maui app to upload to dropbox
Hi, I want to develop an app with .net maui for just five people. One function of this app is to upload files (mostly photos) to one Dropbox. Can this be done without forcing them to enter the Dr...

Hi Gcleanwood,
There is always some way. You can always pre-generate credential information that becomes part of your application. Such a way targets server side applications and is strongly discouraged to be used in user side applications (like the one you plan create). Cons for using pre-authorized application is that everybody that take access to your application (somehow; doesn't matter how exactly) will gain access to the target account (i.e. security issue)! Another cons of using common credentials is inability of users to control alone the access; for instance if somebody (like you) by mistake invalidate the credentials, all users become affected and the application has to be distributed with valid credentials anew (or some patch, at least). 🤔 The choice is yours, but better create application that manage user access in a regular manner and all users get access to their accounts while sharing needed content (that on another way may be managed by the same or other application). Of course, many other factors (usage specifics) may impact weight of all pros and cons and affect your decision.
Good luck.
Thanks for the quick reply!
Would it be better to share a password secured folder? The password would be handed over separately. Or is it even possible to share that folder secured by OAUTH, with different credentials for each user?
Thanks, and have a nice weekend!

There is NO such thing like "password secured folder". Don't mess password protected shared link, it's different thing! You cannot upload something using such link; such way may be used if you need to inspect/download something already in the account (i.e. in opposite direction).
Folder is secure shared to desired account(s), those you want to. You can share with different access privileges - like view only or edit. You don't need additional password for all of this and it's not supported. Again additional password is usable for shared link pointing either to file or to folder; only for a link additional password has some meaning.

😀Seems you mess authentication/authorization with actual actions (including sharing). They are different things! 😉 Pay attention. OAuth 2 is needed to gain access to some/any particular account and initiate any action you may need. And yes, there are endpoints serving shared folders, available using all SDKs if you would use some.
You can use Dropbox Java SDK/Dot NET SDK. Take a look here/here for PKCE OAuth2 flow tool. Here/here you can see Dropbox client documentation. Some examples/examples are available too.
Hope this helps.
