About Events

Events are triggered when specific conditions on your app or a user’s site are met. You can write code that runs when an event occurs.

For example, an event might be triggered when an eCommerce order is canceled. You can implement logic that sends an email to the site visitor when the event is triggered.

How you handle events depends on which frameworks and APIs you use to build your app:

• In Wix Blocks, you can handle events using Velo.
• When self-hosting, you can implement webhooks over REST.
• If you're using the Wix CLI, you can work with events using event extensions.

Where to find event information
