title: Python Requests Params
body: <p>I'm working with a script that downloads comments from YouTube. The script isn't using the API, it is scraping the comments by using Python's Requests module &amp; lxml. My question is, how do you find out what parameters you can use when sending a POST request?</p>
  
  <p>Below are the params used to send in the request.</p>
  
  <pre><code>        params = {'action_load_comments': 1,
                    'order_by_time': True,
                    'filter': youtube_id}
  </code></pre>
