Overview

The snippet must be implemented in the shopping basket page to monitor users who abandon the conversion funnel.

The viewBasket event

Keeps track of the shopping cart with its contents. In this case items have to be provided as full objects, since you will have to provide at least one attribute: quantity.

_trx.push({
    event: 'viewBasket',
    items: [{
        id: 'ABC123', // REQUIRED
        quantity: 1, // REQUIRED
        price: '123.23', // String is preferred
        name: 'Example',
        categoryId: 123, // Google category ID
        categoryName: 'Custom o Google category name'
    }]
});
