Hi @daniel_cleayweb.
Sorry for the late reply. We didn’t get a notification of your comment for some reason. To answer your question, the example I made for @Mikeyjay11 is only one approach. I have instructions on how to setup dropdown variations (with price modifiers) with conditional visibility if variations aren’t available for a product. Mind shooting me an email and I’ll get that info to you: hello@foxy.io
As far as integrating with Webflow’s API once released, we’ll definitely look into it. We actually offer the technology needed for Webflow to make Foxy ecommerce a native feature. Maybe if enough Webflow users vote on it, it will happen. 
Thanks,
Josh
