I have noticed that there isn't any addon in marketplace that can export cs cart products to facebook ads manager and create product catalogue in facebook pixel.
The idea i think is similar to google export xml.
Create product xml with cs cart products with their facebook pixel so you can create facebook product catalogue in your ads account.
I'm going to dive into this in the next couple of weeks. If anyone has experience already, that would be appreciated. @cs-cart almost all stores have links to their products on instagram now because they have apps (add-ons) that do this. A manual on how to do this with cs-cart is much needed.
