Unable to authenticate Google Drive - Error 403: access_denied

[Vanshita_Bafna1]

Hi everyone,
I’m trying to set up a Google Drive trigger in n8n.cloud but I’m unable to authenticate my Google account.
When I click to connect my Google Drive account, I get this error:
“Access blocked: n8n.cloud has not completed the Google verification process”
Error 403: access_denied
My email: [email protected]
I need to monitor a Google Drive folder for new documents. Is this a known issue? Can someone from the n8n team add me to the test users list?
Thanks for any help!

It could be one of several issues, depending on how you are trying to authenticate to Google. Each of the common issues has been discussed many times in the forums. You’ll probably find an answer if you review some of the previous discussions and match up an answer to your circumstances. Start with this search.

This could be the issue with your OAuth consent screen setup in Google cloud project. Make sure you have whitelisted your n8n host as a callback URL in your project, also the callbackurl provided by google drive node in n8n should be whitelisted.

Assuming you have already enabled the google drive API access in your cloud console and did setup the web app properly. Following these checks should resolve your issues, I faced the similar problem and it worked for me. Please let me know if that works for you. Cheers!
