Adding code widget from third party software?

So this is the code ive been provided with:

I cant seem to figure out how i should put it on our website...

I think the base script should be injected in the header/footer and the HTML is the widget script? I just dont know where to put my "Widget script"

website url: https://gar-nectarine-yjtx.squarespace.com/

                        
<script charset="UTF-8" type="text/javascript" src="https://online.bookvisit.com/Content/flexwidget/FlexWidgetFullScripts.min.js"></script>
                        
                    

                        
<script charset='UTF-8' type='text/javascript'>
(function($) {
$.ajax({
dataType: 'json',
url: 'https://online.bookvisit.com/v2/widget/getwidget?channelId=b0fce848-6879-47dd-917b-17ec23301cbe&culture=sv-SE&containerId=widgetContainer&layout=Standard2ColumnsCompact&openOption=NewWindow&displayPromoCode=False&displayCorpCode=False&displayIATACode=False&jsoncallback=?',
xhrFields: { withCredentials: true },
success: function(json) {
$('#widgetContainer').html(json.Widget);
}
});
})(bvJQuery);
</script>

                    
                

                        
<div id='widgetContainer'></div>
                    
           

Hi,

Normally, the base script will go into the header code injection, the widget script will go in the footer code injection, and the html goes within the code block on the page you want it to be displayed.

Hope this helps!
