title: How do I trigger an Airflow DAG via the REST API?
body: <p>The 1.10.0 documentation says I should be able to make a POST against /api/experimental/dags//dag_runs to trigger a DAG run, but instead when I do this, I receive an error:</p>
  
  <pre><code>&lt;!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN"&gt;
  &lt;title&gt;400 Bad Request&lt;/title&gt;
  &lt;h1&gt;Bad Request&lt;/h1&gt;
  &lt;p&gt;The browser (or proxy) sent a request that this server could not understand.&lt;/p&gt;
  </code></pre>
