POL and modern authentication...

Brass Contributor

Hi team 

At the moment my colleague cannot create an app in POL as the client is using modern authentication.  The client is reluctant to use the old legacy authentication.  Does anyone know of a way around this or if MS is planning to get this fixed?

Many thanks

Hello @James_Price ,

We have apps that auth with no issues when the customer has blocked legacy auth in SharePoint, try using Azure AD. You can create a new app registration then under SharePoint on the Request API permissions you'll see EnterpriseResource, Project, ProjectWebApp, ProjectWebAppReporting, TaskStatus.

Hope that helps


Hi Paul 

This what we followed. Authentication is successful but we are unable to fetch data.  Any thoughts on this?

Many thanks
