#  To further clarify, see OAuth 2.0 Authorization Flow

#  This example is for desktop applicatons (it is not for code that runs on a web server).

#  This is the way to initially obtain the OAuth2 access token.  Afterwards it can be 
#  repeatedly refreshed without user interaction, as shown in this example: Refresh Wish OAuth2 Access Token.

#  For a desktop app, you must provide a script on your web server to redirect to "http://localhost/<portNumber>"

#  Your applicaton must use your own public web server as an intermediate
#  to receive and forward the redirect to localhost.
