Answer 1

Your regex is capturing one character in the range between the square brackets. Try:

([0-9A-Za-z]*:[0-9A-Za-z]*)

You can use a website to test regex in real time like this one http://www.regexr.com/

I assume you want the Auth token to enable login authentication in the request. Here is a tutorial on a means of accomplishing this task.
