I am trying to connect with ClickUp.
When I create an OAuth2 connection, the OAuth Callback URL is
http://localhost:5678/rest/oauth2-credential/callback, rather than the subdomain where n8n is installed.
Do I need to change the permalink in a configuration setting?
Thanks,
Josh
Yes, your setup is not complete. You can find instructions for a production setup here:
What is specifically missing here is the environment variable WEBHOOK_TUNNEL_URL. You can find the documentation here:
Hello Jan, how are you? The documentation mentioned above for setting up WEBHOOK_TUNNEL is no longer available - do you have the updated link? We are trying to setup the callback url. Thanks!

Hey @Sergio_Spieler!
Were you able to configure the WEBHOOK_TUNNEL variable? Let us know if you need more help 
Hi,
I’m curently running a self hosted instance of n8n on an debian VM
I couldn’t find a solution to configure the WEBHOOK_TUNNEL variable to be able to create a credential for Microsoft via OAuth.

Hello, it seems to be WEBHOOK_URL now ? I will check…

I confirm the solution, that’s the right command to “adjust” the webhook URL on “auth settings” for the http request, thank you.

I have the same problem.
I am trying to connect with Google Sheets.
When I create an OAuth2 connection, the OAuth Callback URL is
http://localhost:5678/rest/oauth2-credential/callback , rather than the subdomain where n8n is installed.
I did it - export WEBHOOK_URL=https://mysite.com , but it does not work
Do I need to change the permalink in a configuration setting?

Hey @aigor9534,
Just the webhook url option with do the job but depending on your setup getting the option to apply can be different.
With docker I like to recreate the container to be safe.
Hello Jon,
I installed it with npm.
Do I understand correctly that when installing with docker this problem is solved by specifying export WEBHOOK_URL ?
If so, is it correct to remove with npm uninstall n8n and reinstall with docker?
Hey @aigor9534,
You can use it with npm as well if you set the environment variable then start n8n.
Hey @Jon,
I do not understand what I need to do else.
Please, look at image.
Hey @aigor9534,
Can you try…
export WEBHOOK_URL=“https://app10-igor.chatarchitect.com/” | sudo n8n start
Hi @Jon,
Unfortunately, that didn’t work either.
What about…
export WEBHOOK_URL=https://app10-igor.chatarchitect.com
n8n start
Does that work? Just have it a bash here and it does the trick for me.

@Jon, why does it not works with sudo n8n start ?
Only n8n start
Thanks,

Hey @aigor9534,
With sudo something like sudo WEBHOOK_URL=https://app10-igor.chatarchitect.com n8n start would probably do it or use the -E option with sudo.
