Is it possible to add the Whatsapp button to my website?

It is easy to add the WhatsApp chat service to one or more of your Pressero storefronts.
Take a look into the following snippet code, copy and paste it in a text tool, such as Notepad++, VisualStudio, etc., and edit your contact details before entering in Pressero:
<!-- widget -->
<script type="text/javascript">
    (function () {
        var options = {
            whatsapp: "+34666000000", // WhatsApp number
            call_to_action: "Short Message", // Call to action
            button_color: "#4dc247", // Color of button
            position: "right", // Position may be 'right' or 'left'
            pre_filled_message: "Your prefilled message", // WhatsApp pre-filled message
        var proto = document.location.protocol, host = "", url = proto + "//static." + host;
        var s = document.createElement('script'); s.type = 'text/javascript'; s.async = true; s.src = url + '/widget-send-button/js/init.js';
        s.onload = function () { WhWidgetSendButton.init(host, proto, options); };
        var x = document.getElementsByTagName('script')[0]; x.parentNode.insertBefore(s, x);
<!-- / widget -->
