I'm trying to get started with opening a shopify store and the API. However, I'm having trouble conceptualizing how to actually use the API.
I just created a private app and hooked it up to my Ruby on Rails app using the gem they provide: https://github.com/shopify/shopify_app
I started up my local server, and everything looks fine. But where do I go from here? I'm still not too sure on how I could use my RoR app in my actual store.
One of the things I want to do is use one of my RoR views (the homepage lets say) and load it in place of the one liquid layout provided by default from shopify. I am confused by the two options I've found so far: the embedded app SDK ( http://docs.shopify.com/embedded-app-sdk ) and the application proxy ( http://docs.shopify.com/api/tutorials/application-proxies ).
Which one would I use? Could someone go through a step by step process on how I would load my own RoR app view when I visit my shopify store homepage ( myshopify-store.shopify.com/ )?
