Hi!
I'm in a need to develop a system where some external system would access document library (files) inside Sharepoint Online subsite. Which would be the proper course of action?
I cannot use MS Graph due to legal issues of the application.
I tried via OneDrive API but scenario for Sharepoint is not working (tried accessing API endpoint found via discovery service, but no go).
Would some combination of REST calls from here: https://msdn.microsoft.com/en-us/library/office/dn450841.aspx#bk_FileCollection do the trick? I simply cannot found the combination where I can get list of files, or content of any file.
Authorization part is OK and that part is working find (at least it seems so).
Kind regards,
Ivan Hamonajec
