Attribute

A custom property. Attributes are used to store additional information about a Shopify resource, such as products, customers, or orders. Attributes are stored as key-value pairs.

For example, a list of attributes might include whether a customer is a first-time buyer ("customer_first_order": "true"), whether an order is gift-wrapped ("gift_wrapped": "true"), a preferred delivery date ("preferred_delivery_date": "2025-10-01"), the discount applied ("loyalty_discount_applied": "10%"), and any notes provided by the customer ("customer_notes": "Please leave at the front door").
