Introduction

Wix events are fired in your site's backend when certain events occur in your site's store. You can write event handlers that react to these events. Event handler functions receive data that corresponds to the event that has occurred. Use event handlers to create custom responses to marketing events.

To add a marketing 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:

export function <wixAppName>_<eventName>(event) { }

For example, an event handler that handles coupon creation in a Wix site looks like this:

export function wixMarketing_onCouponCreated(event) { }

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