title: Nexmo inbound callback URL
body: <p>I'm attempting to use Nexmo.com to send and receive text messages. Sending works fine, but I am having some issues receiving messages.</p>
  
  <p>My issue is with the Callback URL and what format that page should be in. Nexmo's documentation is <a href="http://www.nexmo.com/documentation/#mo">here</a> and says this</p>
  
  <blockquote>
    <p>Inbound Message</p>
    
    <p>If you have purchased long virtual numbers, you will need to set up a CallBack URL for inbound to which we will send a request for each incoming message. Nexmo will be expecting response 200 OK, or it will retry.</p>
    
    <p>The request parameters sent via a GET (default) to your URL include the following parameters.</p>
  </blockquote>
  
  <p>Am I missing something extremely simple? Is there somewhere that I haven't found with an example of a Callback URL page? Thanks for any help!</p>
  
  <p><strong>Edit</strong>: For clarification, I'm using Nexmo's provided java library, but since their api is all built around URL's the java program simply visits a URL to send the message. <a href="http://www.nexmo.com/documentation/libs/index.html">Here</a>
