## Introduction

Online shopping carts are critical to e-commerce - a place of high opportunities and also high risks.

It is the step of the customer journey where the users often hesitate, and it is important to motivate them not to abandon the cart and complete the purchase.

It is at the same time a great place for presenting the users useful accessories to products in the cart, increasing both the user’s satisfaction and the order value.

Recombee can help you with these goals by providing personalized recommendations that take into account the products in the cart.

## Scenario Setup

In the Recombee Admin UI, navigate to the **[Scenarios](/scenarios)** section and choose **Create Scenario**.

1. Enter a **Scenario ID**. Select a distinctive label for your recommendation scenario, such as _"cart"_
2. Choose **Recommendation type** \- _[Items to User](/api#recommend-items-to-user)_

## Logic

The [Logic](/recommendation_logics) defines the behavior of the recommendation engine.

* Choose the **[ecommerce:cross-sell](/recommendation_logics#ecommerce-cross-sell)** logic type from the **E-commerce** models

This Logic allows for recommendations of products that are compatible with those that the user has already [put into the cart](/api#add-cart-addition).

The Logic needs purchase data for returning correct suggestions - therefore if you have a new database and you want to start using this Logic right away, it is good to do an import of the historical purchase data.

## Filters

Available Products (Global Settings)

You always want to recommend only the products that are in stock. Therefore you need to apply a [**Filter**](/scenarios#filters) rule to allow only such products.

As it would be tedious and prone to error to add this rule to all the Scenarios, this rule shall be added to the [**Global Settings**](/scenarios#global-settings), so it is always applied everywhere.

You can select a **predefined rule from the Recombee Library** to allow only the available products.

Depending on how you represent availability in the catalog, it can be **one of the following rules:**

* **Not deleted items** \- when you have a _deleted_ property (true/false)
* **Available items** \- when you have an _available_ property (true/false)
* **Items in stock \[Google Merchant\]** \- when you have a string _available_ property with _"in stock"_ as its value

## Requesting Recommendations

There are three ways to get recommendations.

1. **[No-Code Widget](/no-code-widgets)** \- create a No-Code Widget using the **visual editor in the Admin UI**.
2. **[Widget SDKs](/widget-sdks)** \- use the SDK for a [Carousel](/widget-sdks#carousel), [Grid](/widget-sdks#grid) or [Feed](/widget-sdks#feed) to display the recommendations in the design of your choice. Use the [Recommend Items to User endpoint](/api#recommend-items-to-user) when initializing the widget.
3. **[API SDK](/api_clients)** \- request the [Recommend Items to User endpoint](/api#recommend-items-to-user) of the Recombee API using an SDK of your choice.
