When you fulfill an order in Shopify, the app automatically creates a shipment announcement with BH Pošta, retrieves the tracking number, and writes it back to the Shopify order — the customer receives a tracking email with no manual work on your end. Requirements: API credentials (UserIdentifikator, APIkey, and endpoint URL) are required. These are provided by BH Pošta after signing the BHPostExpress service agreement.

• Automatic shipment announcement creation when an order is fulfilled
• Manual shipment creation directly from the app
• Real-time shipment status tracking
