const url = 'https://api.correios.com.br/shipment'; // Replace with the actual endpoint
const apiKey = 'YOUR_API_KEY'; // Replace with your actual API key

async function prepareShipment(shippingData) {
    try {
        const response = await fetch(url, {
            method: 'POST',
            headers: {
                'Content-Type': 'application/json',
                'Authorization': `Bearer ${apiKey}`
            },
            body: JSON.stringify(shippingData)
        });
        
        if (!response.ok) {
            throw new Error('Network response was not ok');
        }
        
        const data = await response.json();
        console.log('Shipment prepared successfully:', data);
    } catch (error) {
        console.error('Error preparing shipment:', error);
    }
}

// Example shipment data
const shipmentData = {
    sender: { /* sender details */ },
    receiver: { /* receiver details */ },
    package: { /* package details */ },
};

prepareShipment(shipmentData);
