In this first step we executed the “https://www.dropbox.com/oauth2/authorize?client_id=fcfu96aau5vs2rw&response_type=code” call in postman we got the below response with 200 OK (which is success message)

But the same call when executed in browser we observed the following behavior ,

After selecting “Allow” button we observed the below Screen

But the behavior should be like when we call the API ,Dropbox should return “user code” and URL where we enter the “user code” to authenticate.
We didn’t find the above mentions behavior.
STEP2: The code which we got from above step “9UOc7IydP3AAAAAAAAAAtN-x3o5OKWxmJYiZ6Q0RtB4” is used as Authorization code for the below API call to get access token
