How can I maintain a stable Google Docs credential connection in n8n?

Hello everyone,
I’m using n8n to automate my workflow and have encountered a recurring issue with the Google Docs credential. Although the connection works initially, it disconnects automatically after X hours, requiring a manual reconnection every time. Interestingly, the Gmail credential (linked to the same Google account) works flawlessly, which makes the Google Docs issue even more puzzling.
Here’s what I’ve tried so far:
- Using Google Docs as a database to retrieve information and generate responses.
- Testing an alternative like Pinecone, which, however, provides outputs that are noticeably less precise and qualified compared to Google Docs.
My questions are as follows:
- Is there a way to resolve the Google Docs credential disconnection issue? Perhaps by maintaining the session or automatically refreshing the token?
- What alternative to Google Docs would you recommend for efficiently storing and querying templates within n8n?
I’d greatly appreciate any advice or insights. Thank you!

Below is some troubleshooting advice and recommendations based on the available documentation:
1. Troubleshooting the Google Docs Credential Disconnections
-
Automatic Token Refresh:
n8n’s OAuth2 flow is designed to automatically refresh tokens. If your Google Docs credential is disconnecting, it could be due to a misconfiguration in your OAuth setup. -
Check OAuth Configuration:
• Ensure that the authorized redirect URI in your Google Cloud Console exactly matches the OAuth Redirect URL provided by your n8n credential.
• Double-check that your OAuth consent screen and project settings have been properly configured following the official guide. -
n8n Environment Variables:
If you’re self-hosting n8n, verify that your external URLs are correctly set. In particular, confirm that theN8N_EDITOR_BASE_URLandWEBHOOK_URLenvironment variables use fully qualified domains. Any discrepancies here can lead to issues with token refresh and session persistence. -
Google Verification:
Sometimes, if your app isn’t fully verified by Google, you might notice unusual session behavior. Although the Gmail credential appears stable on your account, ensuring that your OAuth consent screen is properly set up may help alleviate disconnection issues with Google Docs as well.
2. Alternative for Storing and Querying Templates
-
Google Sheets:
A commonly recommended alternative within the Google ecosystem is Google Sheets. Its nodal support in n8n is robust, and many users have found it to be more reliable and easier to query than a Google Docs-centric approach. Google Sheets:- Offers stable OAuth2-based integration within n8n.
- Provides a structured, tabular format that can simplify storing and querying template data.
- Is widely used in automation contexts for similar purposes.
-
Other Options:
While solutions like Pinecone were tested, users have noted that the level of precision and overall functionality may not meet certain needs. For a balance of ease-of-use and reliability, sticking with Google Sheets or even exploring a dedicated database might be worth considering if you require more structured querying capabilities.
By reviewing and fine-tuning the OAuth configuration and ensuring that your n8n environment variables are correctly set, you may resolve the unexpected disconnections with Google Docs. In parallel, switching to Google Sheets could provide a more stable and query-friendly alternative for your template storage needs.
I hope this helps!
