Authentication

By default, this processor uses Google Application Default Credentials (ADC) to authenticate with Google APIs.

To set up local ADC authentication, use the following gcloud commands:

  • Authenticate using Application Default Credentials and grant read-only access to your Google Drive.

    gcloud auth application-default login --scopes='openid,https://www.googleapis.com/auth/userinfo.email,https://www.googleapis.com/auth/cloud-platform,https://www.googleapis.com/auth/drive.readonly'

  • Assign a quota project to the Application Default Credentials when using a user account.

    gcloud auth application-default set-quota-project <project-id>

    Replace the <project-id> placeholder with your Google Cloud project ID

To use a service account instead, create a JSON key for the account and add it to the credentials_json field. To access Google Drive files using a service account, either:

  • Explicitly share files with the service account’s email account

  • Use domain-wide delegation to share all files within a Google Workspace

Fields

credentials_json

The JSON key for your service account (optional). If left empty, Application Default Credentials are used. For more details, see Authentication.
