Is the status value of the fulfillments > shipping_status field automatically updated according to the delivery status of the courier? I wonder if I have to change it to API delivered status or if it works automatically when the delivery is completed.
The shipment_status of a fulfillment in Shopify is automatically updated if you’re using a supported carrier and the carrier provides tracking updates. However, if you’re not using a supported carrier or if the carrier does not provide tracking updates, you may need to manually update the shipment_status field using the API.
If the shipment_status field is set to delivered, that means the carrier has reported the package as delivered.
