Send RAW body with HTTP request

Hello everyone,
I’m trying to send some results to InfluxDB, since there is no node available for it I tried using the HTTP API. It’s fairly simple from the command line but I can’t make it work with n8n.

The following is how you will do it using CURL:

curl -X "POST" "http://influx...." \
     -H 'Content-Type: text/plain; charset=utf-8' \
     -d "cpu_load_short,host=server02 value=0.67"

My understanding is that body parameters in the HTTP Request accepts only pairs of key/value and it’s not possible to send RAW data, right? Is there any way I can send just a string like "cpu_load_short,host=server02 value=0.67"?

Welcome to the community @ABeltramo!

You can do what you want like this:

  "nodes": [
      "parameters": {
        "requestMethod": "POST",
        "url": "",
        "jsonParameters": true,
        "options": {
          "bodyContentType": "raw",
          "bodyContentCustomMimeType": "text/plain"
        "bodyParametersJson": "cpu_load_short,host=server02 value=0.67",
        "headerParametersJson": "={{JSON.parse('{\"charset\": \"utf-8\"}')}}"
      "name": "HTTP Request",
      "type": "n8n-nodes-base.httpRequest",
      "typeVersion": 1,
      "position": [
  "connections": {}

Thanks for the fast reply! You should edit it and remove the endpoint url.
This works perfectly, if I’ll find the time I’ll try to convert it to a proper node and make a pull request.

Great to hear that it works!

Ah actually left the URL in there on purpose as it was one from
which is great for testing. But removed it now if you think it is confusing people.
