title: What is the difference between Params and Body in Postman
body: <p>This might be a really simple question but I can't seem to find a clear answer.</p>
  
  <p>In postman, what is the difference between the <code>Params</code> and the <code>Body</code> tabs?. I noticed that when I was trying to perform a <code>PUT</code> request, if I am to add the <code>key</code> and <code>value</code> in <code>Params</code> my <code>PUT</code> request doesn't seem to update what I intend to update but if I perform the <code>PUT</code> request in <code>Body</code> and have the <code>form-data</code> selected than the expected update happens. </p>
  
  <p>So what exactly are the differences?</p>
