title: Configuring Postman to talk to Azure Service Management API
body: <p>I am trying to use Postman Chrome app to make REST calls against Microsoft Azure Service Management API. However, I get the following error </p>
  
  <pre><code>&lt;Message&gt;The server failed to authenticate the request. Verify that the  certificate is valid and is associated with this subscription.&lt;/Message&gt;
  </code></pre>
  
  <p>Here is what I did.</p>
  
  <p>I created a self signed certificate. I uploaded that certificate to Azure Certificate store in the management portal and added the same to the trusted root certification authorities in my windows certificate store. However, I can't still make a valid API call. Can someone guide me down the right path here.</p>
