HighLevel Oauth2 Issue - Invalid Authorization

Questions
1

Hello - i’m having trouble setting up the Highlevel OAuth2 API. I’ve followed the documentation and was able to authorize the setup only 2 nights ago and now the setup is not connected and I keep getting Invalid Authorization errors during the authentication process. I’ve created new keys in my highlevel developer account with no success. Any suggestions on how to troubleshoot would be helpful.

Hi @A_Bradley,

Welcome to the community :tada:

That looks like HighLevel is throwing the Authorization error rather than n8n so the issue is likely to be with the OAuth app on the High Level side.

Make sure the redirect URI and scopes are set and that your user account is for the correct High Level organisation.

Hey Jon - I just deleted the previous app and recreated a new app entirely in highlevel and i’m still getting the error. Any thoughts?
