Workflow start when **Update Cart** event happens. This event can be triggered when the subscriber adds the product to the cart or visits products. Then the workflow will wait a specific period of time before sent.

    });
</script>

```markup
<script>
    sarepush('updateCart', {
        product_id: 99
        product_price: "23$"
        product_name: "Green t-shirt"
    }, function (response) {
        console.log(response);
    });
</script>
```
