# Edit an event

The event editor is where you change what an individual event sends to a destination, and when. Every edit is scoped to that one event on that one connection, so a change to `Purchase` for GA4 has no effect on `Purchase` going anywhere else.

{% hint style="info" %}
You can only edit server-side events. Client-side events can be [enabled or disabled](/event-editor/enable-disable-events.md), but their mappings and trigger conditions can't be edited.
{% endhint %}

## Open the editor

{% stepper %}
{% step %}

### Find the event

Open the destination's [Events tab](/event-editor/getting-started.md) and locate the event you want to change.
{% endstep %}

{% step %}

### Open Edit

Click the **three-dot menu** on the event row and select **Edit**.

## What you can change

Inside the editor you can:

* **Change field mappings** to rename or remap what the destination receives. See [Customize event field mappings](/event-editor/field-mappings.md).
* **Add trigger conditions** to control when the event is sent. With no conditions, the event is always sent; with conditions, it's only sent when they match. See [Trigger conditions](/event-editor/trigger-conditions.md).
* **Pull in extra data** from Shopify metafields. See [Custom Data Sources](/event-editor/custom-data-sources.md).
* **Preview the payload** to see exactly what the destination will receive with your changes applied. See [Event preview](/event-editor/event-preview.md).
