n8n-nodes-discord-lisboa

n8n community nodes for Discord — triggers, actions and interactive prompts built on discord.js v14 and Discord API v10.

Built to solve the persistent issues found in other Discord n8n packages:

| Problem in other packages | How this package fixes it | |---|---| | IPC / separate bot process — fragile on Linux/Windows, zombie processes, 15 s timeouts | No IPC. discord.js runs directly inside n8n's process. | | New WebSocket client created per workflow execution | Singleton client pool — one connection per token, shared across all nodes. | | message.content always empty | MessageContent privileged intent declared explicitly. | | Memory leaks when deactivating workflows | Event listeners removed by reference in closeFunction. | | Deprecated API endpoints (Discord API v6/v8) | All calls use Discord API v10 (default in discord.js v14). | | No proper UI — channel/role IDs entered manually | Dropdowns populated live from Discord REST API. |

Nodes included

Discord Trigger

Starts a workflow when a Discord event occurs. Uses a persistent WebSocket connection (Gateway). Supported event types:

• New Message — with pattern matching (any, @bot mention, contains, starts with, ends with, exact, regex)
• Message Updated
• Message Deleted
• Reaction Added / Removed
• Member Joined / Left / Updated
• Role Created / Deleted / Updated
• Voice State Changed (user joins, leaves, mutes, etc.)
• Scheduled Event Created / Updated

All trigger types support filtering by server, channel (multi-select), role (multi-select), and user ID.

Discord Action

Performs Discord actions. Pure REST — no WebSocket required. Supported operations:

• Send Message — plain text, optional reply-to
• Send Embed — title, description, color, image, thumbnail, footer, author, fields
• Edit Message
• Delete Message
• Add / Remove Reaction
• Get Messages — fetch recent messages from a channel (with pagination)
• Create Channel — text, voice, announcement, or forum; optional category and topic
• Delete Channel
• Create Scheduled Event — external, voice, or stage; configurable start/end time and location
• Delete Scheduled Event
• Get Guild Info

Discord Interaction

Sends a message with Confirm / Cancel buttons and waits for a user to click one. Produces three output branches:

• Confirm — user clicked the confirm button
• Cancel — user clicked the cancel button
• No Response — timeout elapsed without a click

Configurable: button labels, timeout (5–300 s), restrict to a specific user, optionally delete the prompt message after a response.

Prerequisites

1. Create a Discord Bot

1. Go to discord.com/developers/applications → New Application
2. Navigate to Bot → Add Bot
3. Copy the Bot Token (keep this secret)
4. Copy the Application ID from General Information

2. Enable Privileged Gateway Intents

Still in the Bot tab, scroll to Privileged Gateway Intents and enable all three:

• Server Members Intent
• Presence Intent
• Message Content Intent ← required for reading message text

Without these, the trigger fires but content will be empty and member-based filters won't work.

3. Invite the Bot to Your Server

Use this URL (replace YOUR_APP_ID):

https://discord.com/api/oauth2/authorize?client_id=YOUR_APP_ID&permissions=8&scope=bot

permissions=8 is Administrator. For a minimal setup, use the specific permissions your bot needs (Send Messages = 2048, Add Reactions = 64, Manage Channels = 16, etc.).

4. Get Your Server (Guild) ID

In Discord: Settings → Advanced → Developer Mode (enable it).
Then right-click your server name → Copy Server ID.

Installation

Via n8n Community Nodes UI (recommended)

1. In n8n: Settings → Community Nodes → Install
2. Enter n8n-nodes-discord-lisboa
3. Click Install and restart n8n

Manual (self-hosted, no npm publish)

# On your VPS, set the custom extensions directory in n8n's environment:
# N8N_CUSTOM_EXTENSIONS=/home/user/.n8n/custom

mkdir -p /home/user/.n8n/custom
cd /home/user/.n8n/custom

# Clone or copy the built package, then:
npm install n8n-nodes-discord-lisboa

Or if installing from source:

git clone <your-repo>
cd n8n-nodes-discord-lisboa
npm install
npm run build
# Copy dist/ into your n8n custom extensions path

Configuration

Credential: Discord Bot API

In n8n: Credentials → New → Discord Bot API

| Field | Where to find it | |---|---| | Bot Token | Discord Dev Portal → your app → Bot → Token | | Application ID | Discord Dev Portal → your app → General Information → Application ID |

Usage

Discord Trigger — example: respond to messages starting with !

1. Add a Discord Trigger node
2. Set Credential to your Discord Bot API credential
3. Set Trigger Type → New Message
4. Set Message Pattern → Starts with / Pattern Value → !
5. Set Server → select your server from the dropdown
6. Set Channels → select one or more channels (or leave empty for all)
7. Activate the workflow — the bot connects and starts listening

Output fields include: id, content, authorId, authorUsername, channelId, guildId, timestamp, attachments, mentionedUsers, messageUrl.

Discord Action — example: send a message

1. Add a Discord Action node
2. Set Operation → Send Message
3. Set Channel ID → paste the channel ID (right-click channel in Discord → Copy Channel ID)
4. Set Message Content → Hello from n8n!

Discord Interaction — example: confirmation prompt

1. Add a Discord Interaction node
2. Set Action → Send Prompt (with Confirm/Cancel)
3. Set Channel ID and Message → Are you sure you want to proceed?
4. Connect the three output branches: Confirm → next action, Cancel → stop, No Response → handle timeout

Architecture notes

The DiscordTrigger node establishes a WebSocket connection to the Discord Gateway using discord.js when the workflow is activated. Multiple trigger nodes sharing the same bot token share a single connection (singleton pool keyed by token). The connection is destroyed only when all trigger nodes using that token are deactivated.

The DiscordAction and DiscordInteraction (Send Message / Get Messages) nodes use Discord's REST API exclusively — no WebSocket connection needed for outgoing actions.

The DiscordInteraction prompt action reuses the shared WebSocket client to receive button interaction events.

Troubleshooting

content is always empty
→ Enable Message Content Intent in the Discord Developer Portal under your bot's settings.

Channels / Roles dropdowns show "select a server first"
→ Select a server in the Server dropdown first. Channels and roles depend on the server selection.

Bot connects but no events arrive
→ Confirm the bot is a member of the server. Confirm the Server filter in the trigger matches your server's ID.

DiscordInteraction times out immediately
→ The bot needs to be in the channel where the message is sent. Confirm the channel ID is correct.

Cannot read properties of undefined (reading 'bot')
→ The message is partial (not cached). Ensure the MessageContent and GuildMessages intents are enabled.

Updating

When a new version is released:

• Via n8n UI: Settings → Community Nodes → update button next to the package
• Via npm: npm update n8n-nodes-discord-lisboa in your n8n custom extensions directory, then restart n8n
