Beginners question -Interface between wordpress and Unity

hi
I have a virtual vendingmachine made with blender .
The website will be created with wordpress
The animation of the vending machine will be done with unity

I will fill each cubicle with some items and anybody can buy it.

What about the price per item , what about the amount of items in my shopping basket etc.?
I think I need an interface between Wordpress and Unity
Will it be handled by Wordpress or Unity ?
Which program( wordpress or unity) provides these parameters ( price, content of basket etc.)

Can somebody give me some hints ls about my issue

regards
Curieux
