> **Important:** [Upgrade your Customer Match workflows to the Data Manager
> API](https://developers.google.com/data-manager/api/devguides/audiences/display-video/customer-match/upgrade) for an improved developer experience and access to additional features. We don't recommend implementing new Customer Match workflows using the Display \& Video 360 API.

This guide explains how to use the Display \& Video 360 API to create a new [Customer Match
audience](https://support.google.com/displayvideo/answer/9539301), update its membership, and configure a line item
to target it.

## Prerequisites

Before you start this guide:

1. Verify that your Display \& Video 360 partner meets the [requirements for using
   Customer Match](https://support.google.com/adspolicy/answer/6299717).
2. [Generate credentials](https://developers.google.com/display-video/api/guides/quickstart/generate-credentials#generate_credentials) and [configure your
   client](https://developers.google.com/display-video/api/guides/quickstart/configure-client#configure_your_client).
3. Verify that your Display \& Video 360 user has either an **Admin** or **Standard** [user role](https://support.google.com/displayvideo/answer/2723011). One of these roles is required for the partner or advertiser that will own the created Customer Match audience.
