Return Fulfillment Use this resource to create a Return Fulfillment. This allows you to add tracking information to a return. The returnFulfillmentOrderId property is obtained from a return in OPEN status, and it enables the creation of a shipment for the items linked to that return. --- ### Tracking Information Within the tracking object, you can provide the following properties: - number – The tracking number. - url – The tracking URL. --- ### Shipping Label Inside documents.document, you can include the shipping label in PDF format. This file can be printed and used by the end customer for their return shipment. --- ### Behavior and Limitations - Return Fulfillments do not have statuses. - Once created, they cannot be updated. - To make changes, you must first use the Cancel a return for an order resource to cancel the existing return, and then create a new one. - There is no way to track the shipment status through the API. - Whenever a return is created via the API, the tracking company (carrier) is always set to "other". - This follows Shopify’s logic when returns are created programmatically. - The status of the Return itself (not the Return Fulfillment) will remain in OPEN even after creating a Return Fulfillment. - It does not move to CLOSED because refunds must still be processed to fully close the return. - Currently, ecartapi does not support Shopify’s Refund API.
