To change the Zakeke URL from /app/zakeke to something else:

1. Access your Shopify admin.
2. Go to: Apps and then click "Apps and sales channel settings" and then click on: on Zakeke Interactive Product Designer
3. In the "App proxy" section, click on Customize URL , then set the URL you want and click on Save.
4. Edit the template liquid file by adding the following code, with the URL that you set before, in this case /tools/customizer. The code must be placed before the closing of the head tag, as shown in the image:
   

   <script>
     var zakekeUrl = "/tools/customizer";
   </script>
