Retrieve all fulfillments associated with a specific order. A fulfillment represents a shipment of one or more items in the order, including the carrier, tracking number, tracking URL, and list of fulfilled line items. EcartAPI normalizes fulfillment data across platforms that handle multi-shipment orders differently.

This endpoint is essential for post-purchase automation, shipping notification systems, and order tracking integrations.

Note: Some platforms combine fulfillment and shipment data differently. Refer to the platform-specific endpoint for exact field availability.
