Can a non-GUI C#.NET application interact with OneDrive files with no user interaction?

Question

If yes, then how?

I have files on my own OneDr2ive account. I am writing an application that will at times upload and/or download very tiny files to it. The program only runs via Task Scheduler, and should do so with no user interaction.

I have gone down the LiveSDK and OneDrive SDK routes with no joy, trying to get a simple example of fully logging on with Client ID & Secret, with no success.

At this point I am in need of knowing whether what I am trying to do is even possible. I have a similar, but more detailed, question here about OAuth2, which is concerned with the same use case.

TIA

Yes - after the initial authorization.

If the first run of the application there is prompt for username/password and the consent flow validation with the offline_access scope then further authentication attempts will not require user interaction.

No expiration? No timeouts? – Yumi Koizumi Jul 07 '16 at 20:22
There is a limit on the stored refresh token of a year, which could change, whereby you would need to interactively reauthenticate. – Peter Nied Jul 07 '16 at 20:42
Thanks for the answer. It got far too difficult, so we just switched to GSuite, where everything just works. Well, except rsync'ing to it at speed... Thank you! – Yumi Koizumi Apr 15 '17 at 19:37

The primary way of accessing OneDrive as well as SharePoint online is through powershell. Create the process in powershell first. Then once it is working startup powershell from the C# service and use the calls done in the previous step.

See Using the Windows Live APIs from PowerShell to get started on the powershell commands to onedrive.
See a C# example of executing powershell scripts- Execute PowerShell Script from C# with Commandline Arguments

I may have done this wrong, but the new API required me to authenticate via a form. Have you tried this approach with the new API? You (?) put a **TON** of work into it, either way. I would love to see the example migrated for OneDrive! – Yumi Koizumi Jul 07 '16 at 15:07
@YumiKoizumi I have worked on SharePoint online where we authenticate all in powershell calls. I haven't tried an operation on OneDrive yet, but I believe the concept should be scriptable without popping up a authentication form. – ΩmegaMan Jul 07 '16 at 15:11
