Hello Everyone,

I am trying to authenticate Dynamics 365 V9 via Postman but facing a 401 Unauthorized error. Dynamics 365 is on-Premise with ADFS 4.0. I am trying to build an application that needs to talk to CRM WebAPI and perform CRUD operations.

How can I authenticate CRM via Postman to create API requests? Is there any option to get the client id without Azure App registration?
