Support for Shopify Order customAttributes (note_attributes) in Windsor connector#1342

Users want to access to the Shopify Order custom attributes, which in the Shopify API are exposed as customAttributes (also known as note_attributes in the REST API). These fields appear in the Shopify admin under Additional Information in the order details (e.g., payment_additional_amount_paid, billing_additional_address1, shipping_additional_full_address).

Currently, Windsor’s Shopify connector supports standard order fields such as order_note and customer_note, but not the customAttributes array. The customer specifically needs to query these key/value pairs, which are returned in the Shopify API under the Order object:

Request:

• Add support in the Shopify connector for order.customAttributes so that customers can access these additional order-level key/value fields.

• This will allow users to extract third-party app data, additional billing/shipping information, or other custom checkout fields captured in Shopify orders.
