I would like to create several eCommerce sites in Facebook, but I have no idea what might be the best solution.
In my case, two different situations occur:
1 - I already have an eCommerce and I want to sell on Facebook with a single order management (so I need to make a purchase directly on Facebook, but scaling the product from one warehouse, which is also connected to my eCommerce site);
2 - I do not have an eCommerce and I want to sell directly to Facebook without having to move visitors are interested in acquiring, on another website, outside of Facebook.
I know some of you recommend a solution that I can take to resolve my problem? But it must be a reliable solution because I can not run the risk suddenly the store is not accessible (such as the change of the Facebook API). is important that there is a serious company behind.
Thanks in advance to all those who want to help.
