Unable to Connect Google Account in n8n Despite Adding Myself as Test User in OAuth Consent Screen

[Himanshu_meghvanshi]

Hi n8n Community,

I’m having trouble connecting my Google account to n8n using OAuth2. Here’s what I’ve done so far:

• I created a Google Cloud project and set up the OAuth consent screen.
• I added my email (see attached screenshot) as a Test User, and the app is in “Testing” mode.
• I have entered the OAuth 2.0 redirect URI from n8n into the Google Cloud Console.
• The required Google APIs are enabled for the project.

However, when I try to authenticate my Google account in n8n, I’m still unable to complete the connection. I don’t see any option to input my own Client ID/Secret in n8n Cloud-only a “Sign in with Google” button. I’ve tried using incognito mode and double-checked the redirect URI, but the issue persists.

Hi @Himanshu_meghvanshi!

I’ve successfully connected to Google Cloud via OAuth in n8n, so I might be able to help troubleshoot.

Could you clarify which Google credential you’re trying to connect? Also, if possible, please share some screenshots of the steps you’re taking — that would help identify where things might be going wrong.

Here’s what worked for me:

1. I went to Google Cloud OAuth Clients

2. Created a new OAuth client

3. Got the Client ID and Client Secret

4. Under Authorized redirect URIs, I added:

   https://oauth.n8n.cloud/oauth2/callback
   

That was it — connection worked smoothly after that.

Let me know if this helps or if you’re running into a specific error. Happy to take a closer look!
