# List Audiences

> List the audiences on a Microsoft Ads account, including remarketing lists, customer lists, product audiences and in-market audiences

List the audiences on a Microsoft Ads account, including remarketing lists, customer lists, product audiences and in-market audiences. Microsoft leaves system-generated audiences such as All Visitors out of this API, so the web interface can show more than this returns.
