GO High Level Node error

[GustavoSantiagoB]

Describe the problem/error/question

I have an error when authenticating my Go High Level

In the tutorials I see, it always comes with the N8N URL:

https://n8n.growth-consulting.io/rest/oauth2-credential/callback

My URL on the Go High Level node is:

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

With the HTTPS node using oauth 1 it didn't work either, always giving error 400 when connecting to the account

What is the error message (if any)?

Request failed with status code 400

Hey @GustavoSantiagoB,

We have created an internal ticket to look into this which we will be tracking as "N8N-8148"

Hey @GustavoSantiagoB

That error is coming from HighLevel, it looks like you have not set the required scopes in the app.

[GustavoSantiagoB]

@Joffcom we are using the default scopes

Hey @GustavoSantiagoB,

Can you try 1.75 I have just given it a quick test and it appears to be working.
