Add example of postman configuration for authorization Code Flow.

[andruhaASM]

Hello! Thanks for the course.

I cant configure the oAuth account and postman. In Lab 4.3 when trying to hit oAuth from postman I get the following error

invalid_request: The redirect_uri parameter is not valid: "/" If url looks fine, check that you are not including non printable chars

that comes from the oAuth itself. How can I define this parameter? Could you please explain this part in more details?
