If you are using the managed <code>expo-cli</code> workflow, see the guide on <a href="http://docs.expo.io/versions/latest/workflow/linking/" target="_blank" rel="noopener noreferrer">Linking</a> in the Expo documentation for the appropriate alternative.</p></div><p><code>Linking</code> gives you a general interface to interact with both incoming and outgoing app links.</p><p>Every Link (URL) has a URL Scheme, some websites are prefixed with <code>https://</code> or <code>http://</code> and the <code>http</code> is the URL Scheme. Let&#x27;s call it scheme for short.</p><p>In addition to <code>https</code>, you&#x27;re likely also familiar with the <code>mailto</code> scheme. When you open a link with the mailto scheme, your operating system will open an installed mail application. Similarly, there are schemes for making phone calls and sending SMS. Read more about <a href="#built-in-url-schemes">built-in URL</a> schemes below.</p><p>Like using the mailto scheme, it&#x27;s possible to link to other applications by using custom url schemes. For example, when you get a <strong>Magic Link</strong> email from Slack, the <strong>Launch Slack</strong> button is an anchor tag with an href that looks something like: <code>slack://secret/magic-login/other-secret</code>. Like with Slack, you can tell the operating system that you want to handle a custom scheme. When the Slack app opens, it receives the URL that was used to open it. This is often referred to as deep linking. Read more about how to <a href="#get-the-deep-link">get the deep link</a> into your app.</p><p>Custom URL scheme isn&#x27;t the only way to open your application on mobile. You don&#x27;t want to use a custom URL scheme in links in the email because then the links would be broken on desktop. Instead, you want to use a regular <code>https</code> links such as <code>https://www.myapp.io/records/1234546</code>. and on mobile you want that link open your app. Android calls it <strong>Deep Links</strong> (Universal Links - iOS).</p><h3><a aria-hidden="true" tabindex="-1" class="anchor enhancedAnchor_3pqN" id="built-in-url-schemes"></a>Built-in URL Schemes<a aria-hidden="true" tabindex="-1" class="hash-link" href="#built-in-url-schemes" title="Direct link to heading">#</a></h3><p>As mentioned in the introduction, there are some URL schemes for core functionality that exist on every platform.
