Access Project Online OData using App-Only OAuth2 flow RRS feed

  • Question

  • Is it possible to access the Project Online OData feeds with a .Net app using the app-only OAuth2 flow? This scenario is supported in SharePoint Online generally, as described here:


    I've successfully built out and registered a simple console app that can access SharePoint Online resources in this manner. When I point it at the Project Online OData feed I receive a 401 Unauthorized response. 

    Is there a setting in Project Online security I'm missing? Or is this authentication flow not supported?
