Shipment Offers EndpointThis endpoint allows API clients to retrieve available shipping offers from multiple shipping companies based on shipment details provided by the user.The API handles the full workflow internally: it validates shipment data, stores shipper and receiver addresses, creates a draft shipment, and then communicates with integrated shipping providers to calculate and return the best available offers.The response contains normalized shipping offers without exposing internal pricing calculations, making it safe and ready to be consumed directly by client applications (web, mobile, or third-party platforms).This endpoint is protected by API Key & Secret authentication and requires the user to have the appropriate API integration permissions.Typical use cases include:Comparing shipping prices across multiple carriersDisplaying shipping options before checkoutPowering external platforms (e.g. Shopify, custom stores, ERP systems) with real-time shipping offers
