• Or pass in the variables to the URL: http://yoursite.com/?v_sortby=views&v_orderby=desc
• You can replace DESC with ASC if you want the least viewed posts.

Use: <div id="postviews_lscwp"></div> to replace <?php if(function_exists('the_views')) { the_views(); } ?>.
NOTE: The id can be changed, but the div id and the ajax function must match.
Replace the ajax query in wp-content/plugins/wp-postviews/postviews-cache.js with

jQuery.ajax({ type:"GET", url:viewsCacheL10n.admin_ajax_url, data:"postviews_id="+viewsCacheL10n.post_id+"&action=postviews", cache:!1, success:function(data) { if(data) { jQuery('#postviews_lscwp').html(data+' views'); } } }); 

Purge the cache to use the updated pages.

You can obtain the number of post views by adding views to your _fields parameter:
/wp/v2/posts?_fields=views,title
