// EXTREMELY inspired by https://github.com/webdjoe/shopify_apps_script/blob/master/shopify_api.gs

// Create a private App in Shopify admin and insert app password below
// Sheets need to be created before running with columns of desired output set
// Use keys found in Shopify Rest API Order Object as row headers
// https://shopify.dev/api/admin-rest/2022-04/resources/order#resource-object

// Supports the following sheets/order objects with default columns -
// orders - id, number, order_name, name, current_total_discounts, current_total_price, current_subtotal_price, current_total_tax, financial_status, landing_site, created_at, processed_at, processing_method, subtotal_price, source_url, tags, token, total_discounts, total_line_items_price, total_price, total_tax, updated_at
// shipping_lines - order_id, ordered_at, code, price, title, source, discounted_price, carrier_identifier
// discount_applications - order_id, created_at, type, title, value, value_type, code, description, target_type, target_selection, allocation_method, ordered_at
// refunds = id, order_id, ordered_at, created_at, note, transaction_id, kind, amount
// line_items = id, order_id, sku, name, price, title, vendor, quantity, product_id, variant_id, variant_title, total_discount, fulfillment_status, ordered_at
// customer - order_id, ordered_at, id, email, phone, last_name, created_at, first_name, admin_graphql_api_id, updated_at, orders_count, last_order_id
