Describe the problem/error/question

Hello,
I am not able to connect to the n8n API in the Credentials menu. I am however able to access the API via the API Playground and can, e.g. create or delete workflows.

I used http://localhost:5678/api/v1/ as the base url and I pasted the API key from the Settings/n8n API.

Please advise what I am doing wrong here! Thank you very much.

What is the error message (if any)?

Couldn’t connect with these settings
Retry
ECONNREFUSED

Please share your workflow

Hi @bssei, I am sorry you’re having trouble.

You mean this screen, right?

Can you confirm which command exactly you are using to run n8n? Is there perhaps a white spaces anywhere in your base URL field?

And does calling the API directly via the HTTP Request node throw the same error for you, for example like below?

Thank you so much, @MutedJam. There was a white space in the base URL.

Thank you. That is working now.
