How to setup http node haeder?

Use json or raw?

Is there a demo

Hey @Hao_Tan, sorry to hear you’re having trouble here.

I believe using an expression returning your header object would solve the problem. Check out this post for an example:

Probem with JSON/RAW Parameters - HTTP Request

Hey @ChristianV, I just gave this a go on my end and it seems n8n doesn’t like a string in the headers field for your first example. Looks like a small bug to me and I’ll take a closer look into this when I have a bit more time. As a quick workaround I was however able to just return a JSON object through an expression like so: Could you give this a go on your end and see if this does the trick for you as well?
