title: How should I set up the postman to test API for python request.post method
body: <p>I have written my python code as below</p>
  
  <pre><code>import requests
  
  # URL
  url = 'http://localhost:5000/api'
  
  question = 'what is this'
  
  r = requests.post(url,json={'input':question})
  print(r.json())
  </code></pre>
  
  <p>The code is to send a question to an NLP server and return the json of answer.</p>
  
  <p>How should I set up my postman to test it? 
  I copied the url into "Enter request URL" tab, and change the tab on the left to "POST". And what else I should do? Where should I type in my input?</p>
