# Clicked filters

> Send a click event to capture when users select filters.

**Required ACL:** `search`

Use this event to track when users click facet filters in your user interface.

For details where this event is used, see [Event types](/doc/guides/sending-events/concepts/event-types).

<Info>
  You can't send these events for numeric filters.
</Info>

## Examples

For more information about initializing the JavaScript Insights client `aa`,
see [Initialize the Insights client](/doc/libraries/search-insights/init).

```js JavaScript icon=code theme={"system"}
aa("clickedFilters", {
  userToken: "anonymous-123456", // required for Node.js
  authenticatedUserToken: "user-123456",
  index: "YourIndexName",
  eventName: "Brand Clicked",
  filters: ["brand:apple"],
});
```

## Parameters

<ParamField body="eventName" type="string" required>
  Name of the specific event.

  **Format:** 1-64 ASCII characters, except control characters.

  To maximize the impact of your events,
  use consistent event names and consistent formatting—for example, "Product Added To Cart" (always in title case).

  For example, you can adopt Twilio Segment's [object-action framework](https://segment.com/academy/collecting-data/naming-conventions-for-clean-data/#the-object-action-framework).
</ParamField>

<ParamField body="filters" type="string[]" required>
  List of facet filters.

  You can include up to 10 filters.

  **Format:** `${attribute}:${value}`—for example, `brand:apple`.
  Both the `attribute` and `value` in each facet filter must be [URL-encoded](https://developer.mozilla.org/en-US/docs/Glossary/Percent-encoding) individually and separated by a `:`, such as, `"discount:10%25"`.
</ParamField>

<ParamField body="indexName" type="string" required>
  Name of the Algolia index.

  **Format**: same as the index name used by the search engine.

  Some API clients use `index` instead of `indexName`.
</ParamField>

<ParamField body="userToken" type="string" required>
  Anonymous user identifier.

</ParamField>

<ParamField body="authenticatedUserToken" type="string">
  Pseudonymous identifier for authenticated users.

  <Warning>
    Don't include personally identifiable information in user tokens.
