I'm quite new to web development, but I'll check out if App Proxy is the right thing to do.
I'm making an app for Discount Code.
The ideia of my app is that at checkout page the customer had access to the value they have available for a discount, this value comes from an external API.
And then if the customer wants to use the discount, it created in the Shopify Admin API.
I'm having problems here because I can't make requests from the shop.myshopify.com to the Admin API.
So I'm sending the request to an app who's going to take it and then make the request to Admin API, and here's where I'm having problem with AccessToken variable.
I'm not sure if this way is the right one or if I should do the App Proxy.
