# Line Items

## Overview

Each campaign consists of one or more line items.

You can only run ads after creating a campaign and at least one line item.

<Info>
  A line item allows you to select the products and the retailer where you'd like to advertise. Each line item can include multiple featured products but is restricted to a single retailer.

  To advertise across multiple retailers, you must create separate line items for each.
</Info>

Several settings are available to help you manage your budget and optimize ad delivery effectively.

With the Criteo API, you can:

* Manage your retail media line items,

* Configure line items, including budgets, flight dates, bids (for Onsite Sponsored Products), and targeting options (for Preferred Deals),

* Retrieve products from your product catalog to advertise.

* A line item promotes products for ads on a specific retailer.

* Line items include settings such as start and end dates, optional budget controls, and associated retailers where ads are served.

* Campaigns can manage budgets at both the line item and campaign level.

* Several [reports](/retail-media/v2025.07/docs/demand-side-analytics-get-started) are available to measure line item performance.

* Campaigns are limited to 10,000 non-archived line items.

* Line items are automatically archived 90 days after their end date.
