# Campaigns

<Info>
  **New Campaign Taxonomy**

  Criteo campaigns follow a three-tier structure:\
  **Campaigns**, **Ad Sets**, and **Ads**.

  Your marketing objective and Campaign spend limit are specified at the **Campaign** level.

  Targeting controls and bid targets are set at the **Ad Set** level.  Several Ad Sets can be linked to the same Campaign.

  **Ads** are the actual media that is used to address the audience of a given Ad Set. There can be many Ads associated with a given Ad Set.

## **Introduction**

Criteo's **Campaign API** allows you to retrieve information about the current configuration of your advertising Campaigns and create new ones.

Campaigns define an advertising objective and an overall spend limit across your related Ad Sets.

This API allows you to **search** for Campaigns based on filters, **create** campaigns and **update** your Campaigns' objectives and spend limits.
