title: 403 Forbidden error in Postman calling dynamics o365 web api
body: <p>I am trying to call the dynamics <code>O365</code> opportunity entity using web api. I registered an app in azure(same tenant) and created client secret key as well and added the same app as an application user in dynamics with system administrator privilege. Using the details such as <code>'OAuth 2.0 authorization endpoint (v1)', 'Client/Application ID' and 'Client_secret'</code> I could get the access token and records from the entity without any issues using a console application. When I am giving the same details in Postman, I could generate the access token I am getting <code>403</code> Forbidden error. </p>
