title: How do I implement server-side code for a custom Auth0 login form?
body: <p>I'm learning to build a simple web app and I'm using Auth0.com to authenticate users for the application. The instructions(<a href="https://auth0.com/docs/custom-signup" rel="nofollow">https://auth0.com/docs/custom-signup</a>) for creating a sign-up form are pretty simple to me until I make it to the Server Side section at the bottom.</p>
  
  <p>Here's what it says:</p>
  
  <blockquote>
    <ol start="4">
    <li>Server Side</li>
    </ol>
    
    <p>After receiving the request from the client, the JSON contained in the
    body of the message must be enriched with the connection field, that
    indicates in which connection the user must be stored. POST that JSON
    to /api/users and in case that succeeds the user is created.</p>
  
  <pre><code>POST /api/users
  Authorization: Bearer .... access_token ....
  
  {
       email: "...",        // taken from request
       password: "...",
       color: "...",
       food: "...",
       connection: "..."      // added by the server
  }
  </code></pre>
  </blockquote>
  
  <p>What does this mean and how do I finish this? If I create another file on my Azure hosting account, what do I call it? Finally, is this all the code I will need? 
  Thanks.  </p>
