Help with setting up discord outgoing webhook

Describe the issue/error/question

I am trying to set up outgoing webhook on my discord server by setting the INTERACTIONS ENDPOINT URL for my discord bot. (Discord Developer Portal)

I seem to have set everything correctly, but for some reason Discord is still not happy with the response of the webhook, and consequently rejects the URL, with the error:

    "code": 50035,
    "errors": {
        "interactions_endpoint_url": {
            "_errors": [
                    "message": "The specified interactions endpoint url could not be verified."
    "message": "Invalid Form Body"

Please share the workflow

The thing is, when i tried to replicate this scenario in, it works just fine with their URL!
This is the code used there:

const express = require('express');
const bodyParser = require('body-parser');

const { verifyKey, InteractionType, InteractionResponseType } = require("discord-interactions");

const app = express();

app.use(bodyParser.urlencoded({ extended: true }));'/', async (req, res) => {
  const signature = req.get("x-signature-ed25519") ;
  const timestamp = req.get("x-signature-timestamp") ;
  const public_key = '<PUBLIC KEY>';
  const data = JSON.stringify(req.body);
  const isValidRequest = await verifyKey(data, signature, timestamp, public_key);
  const result = {};
  if(req.body.type) result.type = req.body.type;
  if(req.body.type == InteractionType.PING){
    result.type = InteractionResponseType.PONG
  if (!isValidRequest) {

app.listen(3000, () => console.log('server started'));

Can anyone who might have experience with Discord/Express/Nodejs throw some light on the possible issue with my setup or n8n in general?


Information on your n8n setup

  • n8n version: 0.183.0
  • Database you’re using (default: SQLite): Postgres
  • Running n8n with the execution process [own(default), main]: own
  • Running n8n via [Docker, npm,, desktop app]: Docker

Hi @shrey-42, perhaps it’s worth asking on the n8n Discord server as well? I am not usually a fan of cross-posts but in this case you might reach a few folks more familiar with Discord’s API concepts directly on the platform.

I have the same issues to link my discord application to my n8n webhook…
Did you find a solution to fix this issu ?

I’m having the same issue, have you found a solution yet?

same? did you get to a solution?

Yes, put this code in an execution node:

If the execution node gives no output, the verification was successful. You could check this via an IF node as following:

Hey @MeesJ,

After configuring the Interactions endpoint url, how do I receive the events? Do I need to configure something else?

I have already activated and performed this check with my webhook

One more question, do you know how I can listen to specific triggers?

Example: when someone joins the server, enters a voice room or sends a message on a channel?
