# Update signal

XCE allows Partners to load the widget in a state other than the default with custom attributes or trigger events programmatically using the `update` signal.

This type of features work on an as needed basis for each element, which is explained below.

## Using `update` signal

The `update` signal allows you to programmatically trigger our element events.

This is useful for specific customer actions or contexts during their journey that kept them away from any direct element interaction and still being able to trigger the desired event.

#### isError

To programmatically set the element to an error state call `signalLayer.push()` with `update` as the value for the `signal` property and add the input value in the `isError` property as in the following example:

<pre class="language-javascript"><code class="lang-javascript">window.signalLayer.push({
  signal: "update",
  element: "xce-protection-offer",
  isError: true,
<strong>});
</strong></code></pre>

{% hint style="info" %}
This is similar to `dispatchEvent()` difference being we are using XCE Signals instead.
{% endhint %}

## 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://partner-docs.covergenius.com/xcover-elements/client-integration/element-signals/update-signal.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.
