Oauth2 Error Message

I’m trying to connect an app (SignRequest) via Oauth2 credentials. I don’t know what to put into Scope. I tried typing read write in so many ways, but I don’t know what I’m doing wrong. I haven’t found any helpful information so here I am. I hope the pics and information helps.

Error message:


  • n8n version: 0.236.2
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via Docker
  • Ubuntu

Hi @rossonline, welcome to the community!

I am sorry you are having trouble. The error coming from your API says invalid_scope and on your screenshot the Scope field appears to be empty. The documentation from your screenshot reads

we currently only support the ‘read’, ‘write’ scopes

Perhaps you can try adding the read scope to your Scope field in a first step?


Thank you! I did write “read write” into the scope, but I’m not sure if that was the only issue. I did try writing it in so many ways. I believe it may have had something to do with the Authentication. Instead of “Header” I put in “Authentication Bearer ” of course with the token being my actual token.

Thanks again. I’m sure I’ll be posting another question or two soon.
