title: Dynamic Paths in Retrofit
body: <p>I'm trying to access a resource with like <code>http://192.168.1.64:5050/api/{api_key}/updater.info</code>.</p>
  
  <p>How would I dynamically set the <code>api_key</code> parameter? I've tried using a <code>RequestInterceptor</code> without success where the base url is <code>http://192.168.1.64:5050/api/{api_key}</code>.</p>
  
  <pre><code>@Override
  public void intercept(RequestFacade request) {
      request.addPathParam("api_key", apiKey);
  }
  </code></pre>
  
  <p>Are there any other alternatives?</p>
