title: Django Tastypie: How to Authenticate with API Key
body: <p>I'm making an internal API with TastyPie. I have</p>
  
  <pre><code>from tastypie.authentication import ApiKeyAuthentication
  class MyResource(ModelResource):
    Meta:
      authentication = ApiKeyAuthentication()
  </code></pre>
  
  <p>With Auth rules disabled, my API works great. With it on, I get a 401 (UNAUTHORIZED) response no matter what I try.</p>
  
  <p>I'm sure this is one of those things that's really obvious once you've see it in action, but in the meantime, please advise how to to make the request (a GET).</p>
