# Dynamically sending the cart content

The example below illustrates how to fetch the fresh cart content over CORS, leverage that to render the cart tagging and then use the API to sent that information to Nosto.

{% hint style="danger" %}
This example uses advances constructs, leverages CORS, browser modules and may not have compatibility on older browsers.
{% endhint %}

{% code title="" %}

```javascript
/**
 * This example fetches cart content from an external endpoint, uses 
 * that information to render the cart-tagging and then reloads the 
 * recommendations if needed.
 *
 * This snippet is written under the assumption that the data returned
 * by the endpoint resembles the following
 * {
 *   items: [
 *     product_id: "product_id",
 *     sku_id: "sku_id",
 *     quantity: "quantity",
 *     name: "name",
 *     unit_price: "unit_price",
 *     currency: "currency"
 *   ]
 * }

export default function() {
  nostojs(api => {
    fetch("https://www.example.com/cart")
      .then(response => {
        const tagging = cartToHtml(response.json())
        api.setTaggingProvider("cart", tagging)
        api.resendCartTagging();
      })
  })
}
