Wix Activity Counters events are fired on your site's backend when certain events occur related to marketing tags.
You can write event handlers that react to these events. Event handler functions
receive data that corresponds to the event that fired. Use event handlers
to create custom responses to marketing tags events.

To add an activity counters event handler, add an **events.js** file to the **Backend** section of your site if one does not already exist. All event handler functions for your
site are defined in this file.

Event handler functions are defined using the following pattern:
```javascript
export function <wixAppName>_<eventName>(event) { }
```

For example, an event handler that handles the creation of a marketing tag looks
like this:
```javascript
export function wixMembers_onActivityCounterUpdated(event) { }
```

> **Note:** Backend events don't work when previewing your site.
