Upload file to public shared link with Microsoft Graph API ??

Question

Hello,

I would like to upload a file automatically to a link that's provided by a user, specifically a link to either OneDrive or Sharepoint that contains the anonymous write permission. It would be created by the Share functionality with the "Anyone with the link can edit".

I know that probably the UploadSession API needs to be used (https://learn.microsoft.com/en-us/graph/api/driveitem-createuploadsession?view=graph-rest-1.0) but it requires either Delegated or full Application permissions which I do not want to grant for this application.

Is it possible to do this without getting delegated access and without granting broad access permissions for the whole organization?

Hello @Thomas Rosenstein ,

You can grant Microsoft Graph applications access to specific site collections. Using Sites.Selected along with the Sites permissions endpoint in Microsoft Graph allows you to set the specific site collections and access level you want to grant to individual applications.

Hope this helps.
