Example Webservice / API call- Yelp and working through oAuth2

In our API webinar we discussed how oAuth2 works however there is no better way to explain it than to actually work through an example!  In the below video & code I demonstrate how to access Yelp to perform the “handshake” with oAuth1 and receive the oAuth2 authentication.  I also demonstrate using a named Regular Expression to isolate the returned token.
