Problems with Oauth2 API

I wanted to connect with OAuth2 to my service, but after I want to connect to the “account”.
I get the erorr, that the client_id is wrong.

Unfortunalty I cannot see the details of the exact call to /token.
Neither on the client (n8n) or on my server (private)

When using https://oauth.tools/ to test the OAuth2 endpoint of my server (sligthly different client_id to have differend redirect_uri) everything works fine.

Can you tell me how I could find out what is send with the token-Request, so I can give you additional information on where the problem is?

Hi, I guess you are using the “http request” node , using it you must have created a credential in n8n. (that you can find in credentials on the main page) the client _id is a field you have to set in here.

to see any error message, select the http request node in the executions tab and you will see its input/output data :wink:
