401 Unauthorized when trying to Access data via OData

I have created a new local installation of Acumatica as a test bed and created a user with the hope of using OData access to pull the data from Acumatica. The user that I created was assigned the role of API user and the Tenant name is Company.

I can log in as the admin user interactively but when I try to use Postman to simply get a list of OData exposed generic inquiries (I exposed one so there should be something on the list) I simply get the 401 Unauthorized response. The url I am trying to access is: http://localhost/ACUERP/t/Company/api/odata/gi/

Please give me some direction on this.

Thanks in advance!

Can you check the Admin user if you have given the access for ODatav4 user?

 

Thanks
