The example function below will use this as input and return an object with a Receiver, Sender & Lines.

The .filter(x => x.requires_shipping) is used to filter out Products from the Shopify store than is not marked to require a shipment. You can remove this part if you don't need it.

There are a few ways you can construct the Lines array so that it matches the Shopping Cart content.

In this example, it's hard-coded that each item represents one package on the shipment.

const translateShopifyRequest = ({origin, destination, items}, output = {}) => {
    let tmpLineObject = items.filter(x => x.requires_shipping).map((item) => {
        return {
            "References": [{
                "Kind": 23,
                "Value": item.vendor || ""
            }],
            "PkgWeight": item.grams,
            "Number": 1
        }
    })

    output = {
        "Addresses": [{
            "Kind": 1,
            "Name1": destination.name,
            "Street1": destination.address1,
            "PostCode": destination.postal_code,
            "City": destination.city,
            "CountryCode": destination.country
        }, {
            "Kind": 2,
            "Name1": origin.name,
            "Street1": origin.address1,
            "PostCode": origin.postal_code,
            "City": origin.city,
            "CountryCode": origin.country
        }],
        "Lines": tmpLineObject
    }
    return output
}

The Shopify Carrier Service API expects that the response to be a rates object.

The example function below will take the response from GetShipAdvise and return the expected object.

Note: The CustomFields can hold any custom value that you also might need to be returned with the products.

const translateShipAdvisorResponse = ({Products}, output = {"rates": []}) => {
    output.rates = Products.map((product) => {
        let startDate = new Date(Date.parse(product.DeliveryDate))
        let serviceName = (product.CustomFields && product.CustomFields.type) ? product.CustomFields.type : "", 
        let serviceCode = (product.CustomFields && product.CustomFields.servicecode) ? product.CustomFields.servicecode : "",
        return {
            "service_name": serviceName,
            "service_code": serviceCode,
            "total_price": product.Price,
            "description": product.ProdName,
            "currency": product.PriceCurrency,
            "min_delivery_date": startDate.toISOString(),
            "max_delivery_date": startDate.toISOString()
        }
    }) || []
    return output
}

Shipping Rules

The CSR will handle the filtering of products.

The attribute carriervalidation on the CSR node tells the engine if it should use the default carrier validation.

In this example, the default validation is disabled, and custom validation is used directly on the products, both can be used at the same time if needed.
