<h2 id="introduction">Introduction</h2>
<p>The current API version is the <strong>v1</strong>. All the endpoints are prefixed by <code class="highlighter-rouge">/v1</code>.
It’s only available through HTTPS: it’s TLS, or nothing.</p>
<p>The API has been tagged <strong>v1</strong>. However it is not a frozen API. We may and we
will update endpoints and create new ones. But you can be sure we won’t break
the existing. If any major change about the way JSON is structured, we will
keep the right to release a <strong>v2</strong> and so forth.</p>
<p>In any case, we will communicate through our <a href="http://blog.scalingo.com">blog</a>,
<a href="http://changelog.scalingo.com">changelog</a> and <a href="https://twitter.com/ScalingoHQ">twitter</a>
when any change occurs on the API.</p>

<p>The API is not perfectly RESTful, it is more REST-ish. It has been developed to
be easy to use and instinctive, we’ll probably normalize it, in a second version.</p>
<ul>
<li>HEAD Can be issued against any resource to get just the HTTP header info.</li>
<li>GET Get resources, nullipotent operation (no matter how many times you call it, there is no side effect).</li>
<li>POST Used for creating resources. (creation of a new app, or to create an environment variable)</li>
<li>PATCH Update part of resources, as the value of an environment variable.</li>
<li>PUT Update complete resources.</li>
<li>DELETE Used for deleting items.</li>
