N8n error in API (HTTP Request), but works fine on Postman

[gspacheco]

I’m trying to understand why this HTTP request works fine on Postman but it’s not working on n8n.

I’ve been using n8n for several months and thats the only endpoint which doesn’t work

This token is obviously wrong but it’s fine since it does return Code 200, as expected

It looks like your topic is missing some important information. Could you provide the following if applicable.

• n8n version:
• Database (default: SQLite):
• n8n EXECUTIONS_PROCESS setting (default: own, main):
• Running n8n via (Docker, npm, n8n cloud, desktop app):
• Operating system:

In the HTTP request node, turn off “lowercase headers” option.

Thanks @Jim_Le
I was having lots of troubles with the lowercasing of headers, as a sh*t API was requiring uppercase headers for some dumb reason.
Didn’t know this option was added, now I just hope it wasn’t already added when I was wasting a lot of my time with these headers

Thank you guys, it worked. Didn’t know about it and yes, it is dumb haha.
