Overview

This node allows users to create a file in Google Drive using a service account for authentication. It supports both credential-based and manual authentication methods. Users can specify the file name, content (text or base64), parent folder ID, and additional optional fields such as description and MIME type. This node is useful for automating file creation in Google Drive, such as generating reports, saving logs, or uploading documents programmatically.

Use Case Examples

  1. Automatically create a text report file in a specific Google Drive folder after a workflow execution.
  2. Upload a base64 encoded image file to Google Drive with a custom MIME type and description.

Properties

Service Account Email The email address of the service account used for authentication (required if manual authentication is selected).
Private Key The private key from the service account JSON used for authentication (required if manual authentication is selected).
Impersonate Email (Optional) Email of the user to impersonate, requires domain-wide delegation (optional).
File Name The name of the file to be created in Google Drive.

Troubleshooting

  • Ensure that the service account has the necessary permissions to create files in the target Google Drive or folder.
  • If using manual authentication, verify that the private key is correctly formatted and includes proper newline characters.
  • Common error: 'No credentials provided' - occurs if credentials are missing or not selected; resolve by providing valid credentials or switching authentication method.
  • Errors related to insufficient permissions may occur if the service account or impersonated user lacks access rights to the specified folder or Drive.
