# Bought Together & Accessories

![](/img/recipes/e-commerce/bought-together-and-accessories.png) 

## Introduction

The "Bought Together" use case leverages past purchasing patterns to offer complementary products, helping you optimize your offerings and save time. By implementing these recommendations, you unlock new opportunities to increase the number of items purchased, subsequently enhancing your revenue potential.

## 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 _"pdp-bought-together"_
2. Choose **Recommendation type** \- _[Items to Item](/api#recommend-items-to-item)_

## 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 will give you products that are frequently bought with this product, such as its accessories.

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 Item endpoint](/api#recommend-items-to-item) when initializing the widget.
3. **[API SDK](/api_clients)** \- request the [Recommend Items to Item endpoint](/api#recommend-items-to-item) of the Recombee API using an SDK of your choice.

For more information, navigate to the Integration tab of the Scenario in the Admin UI.
