    <h1 class="api-page-header">We hear you like APIs...</h1>

    <p>We have a <a href="/api/endpoints">well-documented API</a> that allows you to build custom integrations, in addition to our <a href="/integrations">existing integrations</a>. For ease-of-use, we've created a Python module that you can drop in to a project to start interacting with our API. There is also a <a href="https://github.com/zulip/zulip-js">JavaScript library</a> that can be used either in the browser or in Node.js.</p>

    <p><strong>Don't want to make it yourself?</strong> Zulip <a href="/integrations">already integrates with lots of services</a>.</p>

    <h3>Installation instructions</h3>
    <h4>Python</h4>
    <p>This package uses <tt>distutils</tt>, so you can just run <code>python setup.py install</code> after downloading.</p>
    <p>If you have <tt>setuptools</tt> installed on your system then the application's dependencies will be downloaded and installed automatically from <a href="https://pypi.python.org/">PyPI</a>. Otherwise, you'll need to make sure you have these Python libraries installed:</p>
    <ul>
      <li><tt>simplejson</tt></li>
      <li><tt>requests</tt> (0.12.1 or later)</li>
    </ul>
    <p>&nbsp;</p>
    <h4>JavaScript</h4>
    <p>Install it with <a href="https://www.npmjs.com/package/zulip-js">npm</a>:</p>
    <pre><code>npm install zulip-js</code></pre>

    <h3>Usage examples</h3>

These code snippets are generated using our very own Zulip tool, by
sending them to myself in a code block, and then using the inspector
to pull out the resulting HTML :)

Sample steps to do:
1. Write code in Zulip message box.
2. Put it in a multiline codeblock and specify a language.
3. Click on 'preview'.
4. Inspect and copy the HTML.

        <p>You can use <code>zulip-send</code> (found in <code>bin/</code> in the tarball) to easily send Zulips from the command-line, providing the message to be sent on STDIN.</p>

<h4>Stream message</h4>
<div class="codehilite"><pre>zulip-send --stream Denmark --subject Castle \
--user othello-bot@example.com --api-key a0b1c2d3e4f5a6b7c8d9e0f1a2b3c4d5{% if api_site_required %} \

--site={{ external_api_uri_subdomain }}{% endif %}</pre></div>

<h4>Passing in the message on the command-line</h4>
<p>If you'd like, you can also provide the message on the command-line with the <code>-m</code> flag, as follows:</p>
<div class="codehilite"><pre>zulip-send --stream Denmark --subject Castle \
-m <span class="s2">"Something is rotten in the state of Denmark."</span> \
--user othello-bot@example.com --api-key a0b1c2d3e4f5a6b7c8d9e0f1a2b3c4d5{% if api_site_required %} \
--site={{ external_api_uri_subdomain }}{% endif %}
</pre></div>

      <p>You can omit the <code>user</code>{% if api_site_required %}, <code>api-key</code>, and
      <code>site</code>{% else %} and <code>api-key</code>{% endif %} arguments if you have a
      <code>~/.zuliprc</code> file.

    <h3>API keys</h3>
    <a name="api_keys"></a>
    <p>You can create bots on your <a href="/#settings" target="_blank">settings page</a>.
    Once you have a bot, you can use its email and API key to send messages.</p>

    <p>Create a bot:</p>
    <img class="screenshot" src="/static/images/api/create-bot.png" />

    <p>Look for the bot's email and API key:
    <img class="screenshot" src="/static/images/api/bot-key.png" /></p>

    <p>If you prefer to send messages as your own user, you can also find your API key on your <a href="/#settings" target="_blank">settings page</a>.</p>
    <p>When using our python bindings, you may either specify the user
    and API key for each Client object that you initialize, or let the binding look for
    them in your <code>~/.zuliprc</code>, the default config file, which you can create as follows:</p>
<div class="codehilite"><pre><span class="k">[api]</span>
<span class="na">key</span><span class="o">=</span><span class="s">BOT_API_KEY</span>
<span class="na">email</span><span class="o">=</span><span class="s">BOT_EMAIL_ADDRESS</span>
{% if api_site_required %}<span class="na">site</span><span class="o">=</span><span class="s">{{ external_api_uri_subdomain }}</span>{% endif %}</pre></div>

    <p>Additionally, you can also specify the parameters as environment variables as follows:</p>
<div class="codehilite"><pre><span></span><span class="nb">export</span> <span class="nv">ZULIP_CONFIG</span><span class="o">=</span>/path/to/zulipconfig
<span class="nb">export</span> <span class="nv">ZULIP_EMAIL</span><span class="o">=</span>BOT_EMAIL_ADDRESS
<span class="nb">export</span> <span class="nv">ZULIP_API_KEY</span><span class="o">=</span>BOT_API_KEY
</pre></div>
    <p>The parameters specified in environment variables would override the parameters provided in the config file. For example, if you specify the variable <code>key</code> in the config file and specify <code>ZULIP_API_KEY</code> as an environment variable, the value of <code>ZULIP_API_KEY</code> would be considered.</p>
    <p>The following variables can be specified:
        <br/> 1. <code>ZULIP_CONFIG</code>
        <br/> 2. <code>ZULIP_API_KEY</code>
        <br/> 3. <code>ZULIP_EMAIL</code>
        <br/> 4. <code>ZULIP_SITE</code>
        <br/> 5. <code>ZULIP_CERT</code>
        <br/> 6. <code>ZULIP_CERT_KEY</code>
        <br/> 7. <code>ZULIP_CERT_BUNDLE</code>
    </p>
