     <para>To test this we save the XML content into a file called <emphasis role="italic">message.xml</emphasis>. We use cURL to dispatch the message the the DHIS 2 demo instance where we indicate that the content-type is XML and authenticate as the <emphasis role="italic">admin</emphasis> user:</para>
     <screen>curl -d @message.xml &quot;http://apps.dhis2.org/demo/api/messageConversations&quot; -H &quot;Content-Type:application/xml&quot; -u admin:district -X POST -v</screen>
+    <para>A corresponding payload in JSON and POST command look like this:</para>

     <para>If all is well we receive a <emphasis role="italic">201 Created</emphasis> HTTP status code. Also note that we receive a <emphasis role="italic">Location </emphasis>HTTP header which value  informs us of the URL of the newly  created message conversation resource - this can be used by a consumer to perform further action.</para>
     <para>We will now pretend to be the mobile user and read the message which was just sent by dispatching a GET request to the <emphasis role="italic">messageConversations</emphasis> resource. We supply an <emphasis role="italic">Accept</emphasis> header with <emphasis role="italic">application/xml</emphasis> as the value to indicate that we are interested in the XML resource representation and we authenticate as the <emphasis role="italic">mobile</emphasis> user:</para>
