Overview

This node operation lists files in Google Drive using a service account for authentication. It supports filtering files with a query string, limiting the number of results, sorting the results, and selecting specific fields to return. This is useful for automating file management tasks, such as retrieving a list of reports, documents, or any files stored in Google Drive, especially in scenarios where service account access is required for domain-wide delegation or automated workflows.

Use Case Examples

  1. List all files containing 'report' in their name, sorted by creation date descending.
  2. Retrieve up to 50 files with specific fields like id, name, and mimeType for further processing.

Properties

Name Meaning
Authentication Choose authentication method: use saved credentials or enter manually.
Service Account Email Service account email address from the service account JSON, required if manual authentication is selected.
Private Key Private key from the service account JSON, required if manual authentication is selected.
Impersonate Email (Optional) Email of the user to impersonate, requires domain-wide delegation, optional for manual authentication.
Options Additional options to filter and control the list of files returned.

Output

JSON

  • json
    • id - The unique identifier of the file.
    • name - The name of the file.
    • mimeType - The MIME type of the file.
    • createdTime - The creation timestamp of the file.

Dependencies

  • Google Drive API
  • Google service account credentials

Troubleshooting

  • Ensure the service account has the necessary permissions to access the Google Drive files.
  • If using manual authentication, verify the service account email and private key are correctly entered and formatted.
  • Check that the impersonate email is set only if domain-wide delegation is configured.
  • Common errors include authentication failures due to invalid credentials or insufficient permissions, and query syntax errors in the filter string.
