body: <p>I have now spent quite a lot of time on this and still can not figure this out. </p>
  
  <p>Here is my template that i have saved in mandrill->outbound->templates</p>
  
  <pre><code>Hello *|USERNAME|*
  
  this is a *|TEMPNAME|* template
  </code></pre>
  
  <p>And here is the post request that i make from command line</p>
  
  <pre><code>curl -A 'Mandrill-Curl/1.0' -d 
  '{"key":"XXXXXXXXXXXXXXX","template_name":"testTemp","template_content" : [],
   "message": {"to": [{"email": "raghu.iitr@gmail.com", "name": "Raghvendra Singh", 
   "type": "to"}], "merge": true, 
   "merge_vars": [{"rcpt":"raghu.iitr@gmail.com",
   "vars":[{ "content:": "random template", "name": "TEMPNAME" }, { "content:": "raghu", "name": "USERNAME" }]}] }}'
   'https://mandrillapp.com/api/1.0/messages/send-template.json'
  </code></pre>
  
  <p>I get the following response </p>
  
  <pre><code>[{"email":"raghu.iitr@gmail.com","status":"sent","_id":"9015df4d0b1b457588670863c7303822","reject_reason":null}]
  </code></pre>
  
  <p>But the email i get doesn't merge the variable and here is the email i get</p>
  
  <pre><code>Hello *|USERNAME|* this is a *|TEMPNAME|* template
  </code></pre>
