title: Copy data from clipboard in postman
body: <p>I use Postman a lot to test APIs. In addition, to authorize those tests I have to execute a program which generates a long signature which then, I copy and paste in Header. For one or two tests, it doesn't seem too much; but doing it for multiple APIs and like multiple times makes it really hectic and stupid.</p>
  
  <p>Out of curiosity, I want to do this whole process automatically. I am able to copy that signature in clipboard(Using Toolkit and Clipboard in Java), but the issue is I don't know how to get from clipboard in Postman's pre-request script. I don't really know if it's possible or not. I apologize in advance if it's redundant or seems a bit stupid, because I haven't really found anything so far and it's purely my curiosity.
  Thanks in advance!!! </p>
