Push Notification
Integrating Push Notification into your website is easy, since you have HTTPS enabled on your website, you just need to follow these 2 steps:
 Upload the following file into the website root (domain.com/sw.js). The website root is generally public_html or html folders on your web server. (required)
Files:  sw.js
 Insert this code into your website (domain.com), preferably just before the head tag ends.
<!-- FlipMail Push Notification -->
<script type="text/javascript">
    (function(d, t) {
        var g = d.createElement(t),
        s = d.getElementsByTagName(t)[0];
        g.src = "https://cdn.flipmail.org/integrate_00000000000000000000000000000000.js";
        s.parentNode.insertBefore(g, s);
    }(document, "script"));
</script>
<!-- End FlipMail Push Notification -->
        Note: If you are using any of our extensions/plugins then the universal code doesn't need to be added on your website. The extension/plugin will add the integration code automatically.
