Retrieve a list of shipping packages configured in the connected store. Packages represent the physical box types or shipping templates used when creating shipments — each with defined dimensions, weight limits, and carrier association. EcartAPI normalizes package data across platforms that model this resource differently.

This endpoint is commonly used before generating shipping labels to select the correct package size, or to populate package selectors in fulfillment UIs.

Note: Package availability and structure vary by platform. Some platforms model packages as saved templates; others associate them directly with orders.
