# Populate shipping methods in Checkout

You can populate the default shipping methods in the [Digital River Dashboard](https://dashboard.digitalriver.com/login). You can also do this by listening to and responding to a shipping callout once a user adds a shipping address within the checkout experience. 

## Set default methods

You can set default shipping methods in the Digital River Dashboard by creating them in the Logistics section of the [Prebuilt Checkout](https://docs.digitalriver.com/digital-river-api/administration/dashboard/settings/prebuilt-checkout) settings page.

1. On the Digital River Dashboard, under Settings, click **Prebuilt Checkout**. The Prebuilt Checkout page appears.
2. Find the **Logistics** section of the page.
3. In the **Default shipping methods** subsection of **Logistics**, [add your default shipping methods](https://docs.digitalriver.com/digital-river-api/administration/dashboard/settings/prebuilt-checkout).
4. Click **Save**.

## Use the shipping callout function

Use the shipping callout function by completing the following tasks:

1. Configure the shipping callout URL.
2. Configure the ability to listen to and respond to a shipping callout.

### Configure the shipping callout URL

To configure the shipping callout URL:

1. On the Digital River Dashboard, under Settings, click **Prebuilt Checkout**. The Prebuilt Checkout page appears.
2. Find the Shipping webhook URL subsection of the **Webhooks** section of the page.
3. [Configure the URL and any basic authentication your endpoint requires](https://docs.digitalriver.com/digital-river-api/administration/dashboard/settings/prebuilt-checkout#configure-a-shipping-callout).
4. Click **Save**.

### Configure the ability to listen to and respond to a shipping callout

When the customer enters an address, your endpoint receives a POST request with the checkout details and the entered shipping address. The `sessionId` is the Digital River Checkout Session ID. The `sessionUpstreamId` is the BigCommerce Cart Identifier. 

The following shows an example:

```
{
    "sessionId": "e77a19a2-0e5a-4b41-b340-4451f1b3023e",
    "sessionUpstreamId": "b304d277-3398-4507-8834-6026b642106c",
    "currency": "USD",
    "shipTo": {
        "address": {
            "line1": "10380 Bren Road W",
            "city": "Minnetonka",
            "postalCode": "55446",
            "state": "MN",
            "country": "US"
        },
        "name": "John Doe",
        "phone": "6519881234",
        "email": "test@test.com"
    },
    "items": [
        {
            "sku": {
                "id": "sku_e102c701-e1fc-4de6-94c7-91f6f58871d4",
                "name": "Blue Jeans",
                "eccn": "8A992",
                "taxCode": "55101504.100",
                "image": "https://cdn11.bigcommerce.com/s-kxzhuipxqw/products/112/images/378/jeans_blue_classic__66844.1668100978.220.290.png?c=1",
                "url": "https://christeststore-d1.mybigcommerce.com/blue-jeans/",
                "physical": true,
                "skuGroupId": "physical-product"
            },
            "amount": 34.95,
            "quantity": 1,
            "id": "60cd34b0-1413-4e52-b8cf-0391f57ae450"
        }
    ]
}
```

Your system should provide shipment details and shipping methods for display. The following example shows how to provide the shipping methods and details:

```
{
  "shipments": [
    {
      "itemIds": [
        "60cd34b0-1413-4e52-b8cf-0391f57ae450"
      ],
      "shipFrom": {
        "address": {
          "city": "Minnetonka",
          "line1": "10380 Bren Rd W",
          "line2": "string",
          "state": "MN",
          "country": "US",
          "postalCode": "55446"
        }
      }
    }
  ],
  "shippingMethods": [
    {
      "amount": 2.99,
      "description": "Standard Shipping",
      "serviceLevel": "Standard"
    },
    {
      "amount": 10.99,
      "description": "Expedited Shipping",
      "serviceLevel": "Expedited"
    }
  ]
}
```

After responding to the shipping callout, the user interface will show these shipping methods.
