Wix CLI Backend Event Extension

Creates event extensions for Wix CLI applications. Events are triggered when specific conditions occur—on a Wix user's site for app projects, or on your project's site for headless projects. Your project responds using event extensions built on JavaScript SDK webhooks; the CLI subscribes your project to these webhooks.

Common use cases: run logic when a contact is created, an order is placed, a booking is confirmed, or a blog post is published.

Quick Start Checklist

Follow these steps in order when creating an event extension.

1. Create event folder: src/extensions/backend/events/<event-name>/
2. Create <event-name>.ts with the SDK event import and handler function
3. Create <event-name>.extension.ts with extensions.event() and a unique UUID
4. Update src/extensions.ts to import and use the new extension

User (manual): Configure app permissions for the event in the app dashboard if required; release a version and trigger the event to test.
