Hi,
Thank you so much for you reply. Actually, I have never heard of FileMaker, but I will most certainly do some research on it and see how it works.
Since I started this topic, I’ve found another solution that I’m currently working on. Apparently, it can be easily done with WooCommerce REST API and with WP API. I will post an update whether it works or not. If it fails, I would appreciate some guidance on FileMaker if it wouldn’t be too much trouble for you..
Thank you once again for the possible solution!
