## Description

Guides developers through client library installation and authentication setup steps for the Data Manager API. Use this skill when a user is getting started with the Data Manager API and needs to setup their local environment, install the client library, or setup access to the API. Don't use for implementing audience or event ingestion logic (use the data-manager-api-audience-ingestion or data-manager-api-event-ingestion skills instead).

# Data Manager API Setup

## Setup Authentication

Refer to [Set up API access](https://developers.google.com/data-manager/api/devguides/quickstart/set-up-access.md.txt)
for more details.

### 1. Enable the API

**Prerequisites**: A Google Cloud project, the Google Cloud CLI (`gcloud`), and
a Google Account with a project role that can enable APIs, such as **Owner**,
**Editor**, or **Service Usage Admin**. Always tell the user about the required
role. If `gcloud` isn't installed, prompt the user to install it first.

```shell
gcloud services enable datamanager.googleapis.com --project={project_id}
gcloud services list --enabled --project=PROJECT_ID --filter="datamanager.googleapis.com"
```

### 2. Generate Application Default Credentials (ADC)

Choose the method that matches the user's scenario:

*   **User account** (API calls are made as the user's own Google Account): The
    Data Manager API scopes are sensitive, so the user must first configure
    their project's Google Auth Platform:
    1.  **Data Access** page: Add the Data Manager API scopes.
    2.  **Audience** page: Set **Publishing status** to **Testing**. Use the
        **Internal** user type for a Google Workspace organization, or
        **External** with the user's account added as a **Test user**.
    3.  Create (or reuse) a **Desktop app** OAuth client and download its JSON
        configuration file.
    4.  The user runs the following command, which opens a browser login:

        ```shell
        gcloud auth application-default login \
          --scopes="https://www.googleapis.com/auth/datamanager,https://www.googleapis.com/auth/cloud-platform" \
          --client-id-file="{client_id_file_path}"
        ```
