I use Standard Microsoft Identity Server Oauth 2.0 . I would like to know what endpoints I have to provide here.
All of those settings come from your application, so it will be a case of checking what is configured in your application. Speak to your dev, as they should know what they’ve configured. (First thing is to check that you have the correct grant type as there are several options).
They will be specific to your app, so no one here can tell you what the values will be.
OAuth 2.0 is a standard so you might want to look it up to understand what each of those elements really are.
