Checking inventory levels

Learn how to retrieve the available quantity and time of inventory items.

In Digital River coordinated fulfillments, you can call the Inventory Levels API to access product availability information at individual warehouses. After you submit an inventory level request, each inventory level object contained in the response is associated with one inventory item and one location.

You can use an inventory level to sequence your checkout and provide product availability information to customers.

Submitting an inventory-level request

When you submit a GET /inventory-levels request, you must provide an array of inventory item identifiers as a query parameter.

You can filter the results by when inventory levels were last updated, whether the product is available, and which warehouse locations can ship the product to a specific country.

If you don't apply any filters, each inventory item identifier you specify in the request returns one or more inventory-level objects. However, the application of search filters, such as available or shipToCountry, may result in your query returning no results. For example, when you use the shipToCountry filter (which must be formatted as an ISO 3166 country code), you'll only get inventory-level information if the product can be shipped to that country.

An inventory level

After you successfully submit a GET /inventory-levels request, a 200 OK response contains a data array. Each element of this array represents an inventory level.

You get one inventory level when a product is located at a single warehouse. However, when a product is warehoused at multiple locations, we provide the inventory level at each location.

An inventory level provides the item's unique identifier, warehouse location, and availability.

Inventory level

{
  "data": [
    {
      "locationId": "afe95639-8181-4b66-86a6-1a9493d5419d",
      "inventoryItemId": "ce4ce2de-530c-4da2-bf8a-f0f8cf059095",
      "available": true,
      "availableQuantity": 6,
      "liveMode": false,
      "updatedTime": "2018-04-25T20:36:00Z"
    }
  ]
}

Product location

The locationId represents the identifier of the fulfiller's warehouse, which contains the inventory item.

Product availability

If the product is available, then the availableQuantity of the inventory level is greater than zero. In these cases, availableTime is null and not returned.

If available is false, then availableTime provides an estimated time for the product to restock (assuming the fulfiller has provided this information). When the fulfiller doesn’t provide an estimated restocking time, then availableTime is null and not returned.

Using an inventory level

You can use an inventory level to provide product availability information to customers. During the checkout process, it can help you determine when to display or conceal a product on your storefront, notify customers when an item is almost out of stock or when it will be available again, display the remaining number of products in stock, and determine if an item is available for shipping to a specific country.

For example, let's say you want to determine the availability of a coffee maker and whether it can be shipped to Sweden. To do this, submit a GET/inventory-levels that specifies the inventory item identifier, the shipToCountry as SE, and sets available to true.

GET/inventory-levels

curl --location --request GET 'https://api.digitalriver.com/inventory-levels?inventoryItemIds=310abe81-69f6-44e5-85df-2674045e5460&shipToCountry=SE&available=true' \
--header 'Authorization: Bearer <API_key>' \
...

In this case, Digital River determines that a machine that can be shipped to Sweden is only available at one location, so the response returns just a single inventory-level object.

Inventory level

{
    "data": [
        {
            "locationId": "20045",
            "inventoryItemId": "310abe81-69f6-44e5-85df-2674045e5460",
            "available": true,
            "availableQuantity": 995,
            "updatedTime": "2021-01-12T06:55:14Z",
            "liveMode": false
        }
    ]
}

Your integration can also use an inventory level to determine whether to reserve an inventory item or create a fulfillment order.
