title: WARNING: Can't verify CSRF token authenticity in case of API development
body: <p>I am right now developing web <strong>APIs</strong> with Ruby on Rails. When the Rails app receives POST request without any csrf token, the following error message shall happen. Because the app has no views.</p>
  
  <pre><code>WARNING: Can't verify CSRF token authenticity
  </code></pre>
  
  <p>So my question is how can I escape csrf token check safely in this case?</p>
  
  <p>Thank you very much in advance.</p>
