WordPress Product Order Pages & Checkout

It was necessary to add 4 pages to the existing site, where the users could buy cameras and plans. All checks and orders should be sent to the Wordpress back-end, and the requests from there should be sent to the client API. So we created 4 pages in Wordpress and sliced the template for each page. All details entered by user are sent to the admin panel via Ajax and if they are valid, the socket connection with the client API is established and the order/authorization/registration/purchase confirmation performs.
