Data Manager API Setup

Data Manager API Setup

Setup Authentication

Refer to Set up API access 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.

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:

     Copy

     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}"

  Unverified app screen: This warning appears because the Data Manager API scopes are sensitive. During Testing, External test users still see it and can continue past it. Before other users can sign in, the app must complete OAuth app verification. Service accounts don't need verification.

• Service account (API calls are made as an app identity instead of a person): For local development, use service account impersonation rather than a service account key, since keys are a security risk if not managed carefully.

  • Grant the Service Account the Service Usage Consumer IAM role (roles/serviceusage.serviceUsageConsumer) on the project.

  • Grant the user executing gcloud the Token Creator role (roles/iam.serviceAccountTokenCreator) on that Service Account.

  • Run:

    Copy

    gcloud auth application-default login \
      --impersonate-service-account={service_account_email} \
      --scopes="https://www.googleapis.com/auth/datamanager,https://www.googleapis.com/auth/cloud-platform"

• Data partner creating partner links in advertiser accounts: Read Partner Links.

Multiple APIs: To use the same credentials for other APIs, append their scopes to the --scopes list in the commands above (e.g., https://www.googleapis.com/auth/adwords for the Google Ads API or https://www.googleapis.com/auth/display-video for the Display & Video 360 API).

Verify: gcloud auth application-default print-access-token prints an access token when credentials are set up correctly.

Troubleshooting PERMISSION_DENIED with a valid token: Add the user or service account to the destination account (for example, the Google Ads account or its manager account). For service accounts, also confirm the Service Usage Consumer role on the Cloud project.

Production: For production authentication (workloads in or outside Google Cloud, apps that act on behalf of other users, or partner links), see Deploy to production.

Install Client & Utility Libraries

Refer to Install a client library for more details.

The companion utility libraries provide pre-built helper classes and functions to correctly format, hash, and encrypt user identifiers (such as emails, phone numbers, and physical addresses) prior to API ingestion. Use of these libraries is highly recommended to ensure that user identifier formatting matches the API's specifications.
