# Product abandoned

Learn how to check if a user has abandoned a product.

This expression checks whether the user has abandoned a product based on [Product abandoned](/reference/event/types/ecommerce/product-abandoned) events.

A product is considered abandoned when a user views the item or adds it to the cart but does not complete the purchase before the session ends. When the session is closed, the cart and its items are marked as abandoned.

> **Tracking required**
>
> Make sure your app is tracking the [Cart modified](/reference/event/types/ecommerce/cart-modified) or [Cart viewed](/reference/event/types/ecommerce/cart-viewed) events before using this expression. Without this event, the expression will always evaluate to false.

## Syntax

The basic syntax for this expression is:

```cql
user has abandoned product
```

You can optionally include the article for better readability:

```cql
user has abandoned a product
```

The negation of the expression can be expressed as:

```cql
user has not abandoned a product
```

You can refine the expression with filters, quantifiers, and time windows:

```cql
user has abandoned a product /*<criteria>*/ /*<quantifier>*/ /*<window>*/
```
