# Overview

This guide explains how to use the Display \& Video 360 API to manage access for
Display \& Video 360 users.

## Prerequisites

Before you start this guide:

1. Create a [Service Account](https://cloud.google.com/iam/docs/service-account-overview).
2. Generate [credentials for your Service
   Account](https://developers.google.com/display-video/api/guides/concepts/general/service-accounts#steps).
3. Configure your client to [authenticate using your Service
   Account](https://developers.google.com/display-video/api/guides/concepts/general/service-accounts#steps) and include the access scope `https://www.googleapis.com/auth/display-video-user-management`, required by user methods.
4. Verify that your Service Account is a Display \& Video 360 user with an **Admin** [user role](https://support.google.com/displayvideo/answer/2723011). This role is required for the partner for which you want to manage user access.
