If you successfully installed Owlcure Analytics into your website, Web Personalizer is ready to use. You can use it for the personalized blocks of products, popups, bars, notifications, etc.
Owlcure App uses iframe in web layers editor. In the iframe, you can see how the new web layer will look on your website. If you are using X-Frame-Options to deny using your website in the iframe, you need to add the following header. Otherwise, you will not be able to see live views of web layers in the Owlcure App. Therefore web layers will still work correctly.
If you are already using Content-Security-Policy header, just add https://*.owlcure.com to the end of the domain list.
The most powerful web layers are using for personalized product recommendation blocks. For this purpose, you should create a Product template in your site design.
