title: Spring RestTemplate most suitable method for sending some data and expecting no return
body: <p>Spring offers three ways in which we could send data to server, <strong>POST</strong>, <strong>PUT</strong> and <strong>Exchange</strong>. </p>
  
  <p>I have a requirement, where I am just sending out an <strong>ID</strong> and a <strong>SecretKey</strong> to server to notify some action, and I am expecting no return from server.</p>
  
  <p>For sending this data I am using <code>MultiValueMap</code></p>
  
  <p>Presently I am using <code>postForObject</code> with <code>ResponseType</code> as null, but at runtime it is giving me error that <code>ResponseType</code> can not be null. So, what would be the best way to handle such scenarios  </p>
