HTTP node help (beginner)

General

Hello, I am new to http nodes and need help from more experienced users.

With inject I send data (POST) to the URL to the RequestBin.com endpoint.
These data are properly displayed there (picture attached).

How to get this data in Node-RED?
Thx!

try the examples in the cookbook or the built in examples inside node-red

Hello and thanks for the reply @Steve_Mcl!

I tried this example before asking the question, but no luck.

I made changes to the "http in" and "http request" nodes (changed URL).

An image with the debug response is attached, as is the flow.

ok, so I have made some assumptions - 1 being this instance of node-red is NOT running on the same server as https://en0pnjpo24h70g.x.pipedream.net/hello-raw?

The HTTP-In creates a callable endpoint on the NODE-RED server - it does not provide a way to intercept calls to another server or another application on a different port.

Does that make sense?

Makes sense.
So it is normal that it does not work for the given example.
Thank you for the explanation!
