Delphi app to manage orders on Shopify using the API (JSON)

This will be a desktop application, built in Delphi, that will use the Shopify API (which is JSON based) to fetch orders from a Shopify account, and display them effectively, so that later we can manipulate those orders. This would probably involve creating a class called 'TOrder' (with all the important fields defined), OR a TClientDataSet (with all the important order fields), OR both?. Orders will then be displayed visually in a grid. We need to have control (at design time is OK) over which fields are displayed and how the orders are filtered and sorted. * If the project is successful, there should be more work on this project in the future. * You are required to release all of the source code and files (i.e. you do not just supply the .exe) * You do not have to know Shopify to do this. However you will definitely need to be familiar with JSON or XML. * The shopify API documentation is here: [login to view URL] Here is an example of how the API works. The URL format is this: https://apikey:password[at]hostname/admin/[login to view URL] So for example if we call: https://xxxxxxxxxxxxx2ebd304083f0exxxxxxx:/admin/[login to view URL], it will return all the orders. Here is just an example of the JSON response, with just 1 order: { "orders": [ { "buyer_accepts_marketing":false, "cancel_reason":null, "cancelled_at":null, "cart_token":"xxx", "checkout_token":"xxxx", "confirmed":true, "created_at":"2014-02-12T20:45:21+11:00", "currency":"AUD", "email":"", "financial_status":"paid", "fulfillment_status":null, "gateway":"paypal", "id":23203xxxx, "location_id":null, "name":"#4xxx0", "note":"", "number":2xx, "reference":null, "referring_site":"", "subtotal_price":"109.98", "taxes_included":false, "test":false, "token":"6a304bf8db68968xxxxxx761d2ae2725", "total_discounts":"0.00", "total_line_items_price":"109.98", "total_price":"119.98", "total_price_usd":"108.22", "total_tax":"0.91", "total_weight":2000, "browser_ip":"[login to view URL]", "landing_site_ref":null, "order_number":1290, "discount_codes": [ ] , "note_attributes": [ ] , "processing_method":"express", "checkout_id":204187401, "source_name":"web", "tax_lines": [ { "price":"0.91", "rate":0.1, "title":"GST" } ] , "line_items": [ { "fulfillment_service":"manual", "fulfillment_status":null, "grams":1000, "id":41057xxxx, "price":"54.99", "product_id":20xxxx021, "quantity":2, "requires_shipping":true, "sku":null, "title":"xxxxxxxtional Bxxxxxg", "variant_id":4616xxx65, "variant_title":"1kg", "vendor":"xxxxxxx xxxxx", "name":"xxxxxxxxxxxxxxxxxxxxx - 1kg", "variant_inventory_management":null, "properties": [ { "name":"Moistness", "value":"xxxxxxxxs" } , { "name":"Sliced", "value":"Whole" } ] , "product_exists":true } ] , "shipping_lines": [ { "code":"Shipping & Handling", "price":"9.09", "source":"shopify", "title":"Shipping & Handling" } ] , "billing_address": { "address1":"8 xxx e", "address2":"", "phone":"xxx-xxx-2769", "zip":"318x", "name":"lxxx xxxxer", "country_code":"AU", "province_code":"VIC" } , "fulfillments": [ ] }
