title: how can i post data using Mozilla rest add-on using mailgun api
body: <p>I'm using this Mozilla  ADD-ON to post the data in mailgun API
  <a href="https://addons.mozilla.org/en-US/firefox/addon/restclient/" rel="nofollow">RestClient</a></p>
  
  <p><code>Content-Type:application/json</code></p>
  
  <p><code>URL</code> I'm using </p>
  
  <p><code>https://api.mailgun.net/v2/sandbox42924.mailgun.org/messages</code></p>
  
  <p><code>Json Data</code> I'm posting</p>
  
  <pre><code>[
      {
          "from": "Kaushik &lt;kaushik@gmail.com&gt;"
      },
      {
          "to": "Kaushik &lt;kaushikfb1@gmail.com&gt;"
      },
      {
          "subject": "Hello This is test mail"
      },
      {
          "text": "Testing some Mailgun !"
      },
      {
          "html": "&lt;html&gt;Hello These &lt;h2&gt;contents belongs&lt;/h2&gt; to html content&lt;/html&gt;"
      }
  ]
  </code></pre>
  
  <p><strong>OR</strong></p>
  
  <pre><code>{
      "from": "Kaushik &lt;kaushik@gmail.com&gt;",
      "to": "Kaushik &lt;kaushikfb1@gmail.com&gt;",
      "subject": "Hello This is test mail",
      "text": "Testing some Mailgun !",
      "html": "&lt;html&gt;Hello These &lt;h2&gt;contents belongs&lt;/h2&gt; to html content&lt;/html&gt;"
  }
  </code></pre>
  
  <p>In both cases what I'm getting is </p>
  
  <pre><code>{
     "message": "'from' parameter is missing"
  }
  </code></pre>
  
  <p>I want to know how i can post the data. </p>
  
  <p>In documentation they have not describe this process.
  I'm curious to know how it is working?</p>
  
  <p>Here is the link for the documentation <a href="http://documentation.mailgun.com/api-sending.html#examples" rel="nofollow">Click Here</a>. They are using library for using in each language. If you know the library in detail you can help. </p>
