Feed on whitelabel site > checkout on source site

Hi. I need to create a product feed that will be displayed on a separate "whitelabel" website. The feed will display exactly the same set of products, organised into their categories etc and allow the customer to navigate in the same way as on the source OpenCart website.
What I need to happen is for the customer to be able to add these products to basket from their whitelabel site and then checkout on the source OpenCart website. Is this possible?

Thanks for any help.

So on the whitelabel site, your client will not have access to the products or orders etc ?

To what extent will your client have access ?

Why not just set-up a multi-site within 1 opencart installation ?

All the stock, products, orders etc will be managed from one back-end.

A white label site separate to the main site would probably have to connect to the main site's database.

One problem you may have amongst others is the session/cookie handling between sites / domains is non-existent in OpenCart. You cannot even use a shared ssl certificate.

Please help in solving the problem.
I want to develop a partnership program with white label.

There are agreements with other sites that are willing to put my storefront on they website.
How i can do that?

Thank you.
