This node allows uploading files to Google Drive using a service account for authentication. It supports both saved credentials and manual entry of service account details. Users can specify the file name, content (text or base64), parent folder ID, and additional metadata such as description and MIME type. This node is useful for automating file uploads to Google Drive in workflows, such as backing up data, sharing files, or integrating with other systems that generate files.

Use Case Examples

  1. Uploading a report generated by another node to a specific Google Drive folder.
  2. Automatically saving form submissions as text files in Google Drive.
  3. Uploading images or documents to Google Drive for further processing or sharing.
