## **Introduction**

Criteo's **Audience API** allows you to manage your contact lists by creating, deleting, and updating audience data that is being used for your advertising campaigns.

Available information that can be managed includes the **name** of your audience , the **description** of the audience, and the **users** included in an audience.

You can also retrieve audience data such as the total **number of users** in an audience and the total number of **matched users** in an audience compared to Criteo's shopper graph.
