I was looking at this myself due to the fact that it looks like it could easily be integrated into a backend PHP or CF console. I noticed that all views in Manager are HTML which in turn leads me to believe that posting entries into the server version should be straight forward.
Right now, it’s possible to interact with API only using .NET language such as C#, VB.NET or similar.
I imagine in future, there could be libraries for PHP and other languages.
So short answer is that it’s unlikely that Manager will be integrated with eCommerce shops in upcoming months. But it is something that could be done sometime next year once PHP is supported (since majority of these eCommerce solutions are written in PHP).
@lubos it would be really great to have it sync with online marketplaces. There are many small businesses on Etsy and Amazon. I read that Etsy does have their API available for 3rd parties to use.
This would be very helpful for auto-sync of buyer transactions, marketplace fees, etc. It would be a great time saver, as an online shop potentially transacts hundreds of items per month.
