google_drive_search

Available in: Cloud, Self-Managed

Searches Google Drive for files that match a specified query and emits the results as a batch of messages. Each message contains the metadata of a Google Drive file.

Try out the example pipeline on this page, which searches for and downloads all Google Drive files that match the specified query.

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.

This field contains sensitive information that usually shouldn’t be added to a configuration directly. For more information, see Manage Secrets before adding it to your configuration.
