Hi, I have setup an Shopify app and have set application proxy endpoint where I am returning liquid template. All works fine. Now I want to get all customer orders (if customer is logged in - this is checked in liquid) and post the information to one of our external services. Since liquid is limited with functionality I cannot normalize the orders in a format that I require. What the approaches I can take to fetch all orders, construct in a format I want to define and post the data to our external services?
