Answer 1

Could you please check the redirect URI from your azure portal, If your app is single page application then you can add homepage ( localhost ) URI

Steps to Add redirect URI from azure portal
Azure Portal > Azure Active Directory > App Registrations > Search the application by using App ID or Name > open the app and click on authentication blade > update the Redirect URI.

Hope this helps

Thanks

Hi @MR , please try to fill in all the parameters in body, and secondly, you don't need to use the %20 symbol between permissions in postman.
