<li>Making HTTP calls against the admin <a href="https://pulsar.apache.org/admin-rest-api#/">REST</a>
 API provided by Pulsar <a href="/docs/en/2.3.1/reference-terminology#broker">brokers</a>. For some restful apis, they might be redirected to topic owner brokers for serving
with <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/307"><code>307 Temporary Redirect</code></a>, hence the HTTP callers should handle <code>307 Temporary Redirect</code>. If you are using <code>curl</code>, you should specify <code>-L</code>
to handle redirections.</li>
<li>The <code>pulsar-admin</code> CLI tool, which is available in the <code>bin</code> folder of your <a href="/docs/en/2.3.1/getting-started-standalone">Pulsar installation</a>:</li>

<p>If you have <a href="/docs/en/2.3.1/security-overview#authentication-providers">authentication</a> enabled, you will need to provide an auth configuration to use the <a href="/docs/en/2.3.1/reference-pulsar-admin"><code>pulsar-admin</code></a> tool. By default, the configuration for the <code>pulsar-admin</code> tool is found in the <a href="/docs/en/2.3.1/reference-configuration#client"><code>conf/client.conf</code></a> file. Here are the available parameters:</p>

 object, specifying a URL for a Pulsar <a href="/docs/en/2.3.1/reference-terminology#broker">broker</a> and a <a href="https://pulsar.apache.org/api/admin/2.3.1/org/apache/pulsar/client/admin/ClientConfiguration">ClientConfiguration</a>
. Here's a minimal example using <code>localhost</code>:</p>
