Export the flow (the inject and http request) and paste it here so we can see what you have done. See this post for how to include a flow in a post : How to share code or flow json

This i the flow i created [err]

A 400 response means the server didn't like your request for some reason. But it hasn't returned a message in the payload to give any indication what the problem may be.

[image] MagicSven: But how can i see any errors in nodered? The message returned by the HTTP Request node already contains all the information the server has returned. You can see the payload is empty - so the server has not provided any error messages to help. All you have is a 400 status co…
