Google Drive Credential Verification Fails for Google Sheets Integration

Want to use over 200+ MCP servers inside your coding tools like Cursor?
Hello, good day.
We are encountering issues with our Google Drive credentials, which are preventing the use of tools like Google Sheets for integration.
A few days ago, we resolved failed iterations with PostgreSQL using a new update. However, as of today, the credentials for Google Drive appear to be failing verification. Even after creating new credentials, the error persists, and it seems the credentials cannot be properly verified.
For example, despite having confirmed the drive credentials, I am still unable to access its internal content.
Environment details:
- n8n version: 1.74.3
- Database: SQLite
- n8n EXECUTIONS_PROCESS setting: own (default)
- Running n8n via: Docker
- Operating system: Windows 10
Could someone please help identify and resolve this issue?
Thank you for your support.

Below is some troubleshooting advice specifically for Google Drive credentials that aren’t verifying properly:
Verify OAuth Redirect URLs
One common cause for OAuth verification errors is that the external URLs set up in Google Cloud don’t exactly match the ones n8n is using. Make sure that the redirect URIs in your Google OAuth client match the URLs derived from your n8n configuration. In a self-hosted setup, verify the following environment variables:
- N8N_EDITOR_BASE_URL
- WEBHOOK_URL
Both should use fully qualified domains (including the protocol, e.g., “https://”).
Check App Verification Status
If you're seeing an error such as “Google hasn't verified this app,” you may need to address this in the Google Cloud Console. Confirm that you've provided the appropriate details (e.g. application name, support email, etc.) on the OAuth consent screen. If the app isn’t verified yet by Google, you might encounter permissions issues until the verification process is complete.
Confirm API Enablement
Even if you created new credentials, ensure that the Google Drive API is enabled under APIs & Services > Library in your Google Cloud project.
Additional Steps
- Revisit the error message—often it includes a link or specific instruction from Google.
- Check for any changes in your n8n instance’s domain or SSL setup that might affect URL matching.
Following these steps should help resolve the issue with Google Drive credentials. If problems persist, double-check all OAuth configuration details on both the Google Cloud side and within your n8n credentials setup.
