Credential problems in node HTTP Request from n8n to Vapi

[Jakob06]

I’m stuck at the HTTP Request node when using n8n and Vapi.
I’ve copied the API key from Vapi, and yet I keep getting this message: Problem in node ‘HTTP Request‘
Authorization failed - please check your credentials.
This is my text in URL: https://api.vapi.ai/call/{{ $(‘Webhook’).item.json.headers[‘x-call-id’] }}. I clicked Send Headers and then wrote below Authorization, then Bearer followed by the Private API key from Vapi with no spaces after Bearer.
Can somebody help?

Describe the problem/error/question

What is the error message (if any)?

Hey @Jakob06, how is it going? Have you tried using the API through Postman?
Perhaps the problem is due to not using space after Bearer.

ATTENTION!

****But I suggest to create Generic Credentials with an Header Auth. *****

I could’ve sworn that I had tried with and without space, but clearly not cuz now I added a space and that solved it Thanks so much!
