This is an highly advanced and quite extensive example of using the Dialog web block to create an authenitcation flow which aquires a token used for accessing Google APIs such as Google+, Calendar, Tasks and Sheet, etc. with the HTTP request block.
Full description of the Google authentication flow:
• Visit https://console.developers.google.com
• Create a project
• Create "OAuth client ID" credentials (API manager)

• The "Client ID" and "Client secret" are required to acquire a token
• Enable the APIs to access
