# 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();
      })
  })
}
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.nosto.com/techdocs/apis/frontend/js-apis/common-examples/dynamically-sending-the-cart-content.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
