title: Rest API -> passing json string as parameter value
body: <p>Is it the recommended way to pass a JSON string as a parameter value in a REST API?
  This is the data which I am trying to send :</p>
  
  <blockquote>
    <p><a href="http://127.0.0.1:8000/v1/product/?productName=" rel="nofollow noreferrer">http://127.0.0.1:8000/v1/product/?productName=</a>&amp;metrics={"memory":2,"disk_space":10}</p>
  </blockquote>
  
  <p>Here, is it ok to pass the value of metrics as JSON value? </p>
  
  <p>Initially, I tried passing the metrics JSON value in the body. As it is not supported/recommended standard I have removed it. </p>
