Connect Langflow to Discord

This recipe puts your Langflow app behind a Discord bot. LangBot receives messages from Discord, runs them through a pipeline, and sends the answer back, so you do not write any platform code.

Langflow builds agents and flows with a drag-and-drop editor. LangBot runs a flow through the Langflow API for every message.

What you need

• A running LangBot instance: LangBot Cloud (no server needed) or a self-hosted deployment with Docker or uvx langbot.
• A Langflow account or instance that LangBot can reach over the network.
• A Discord application with a bot: its Client ID and bot token from the Developer Portal, with Server Members Intent and Message Content Intent enabled.

Networking

Discord bots connect out to the Discord gateway, so no public webhook URL is required.

1. Prepare Langflow

1. Build a flow in Langflow (the Simple Agent template is a good start).
2. Create an API key under Settings.
3. Copy the Flow ID from Share → API access.

2. Create a pipeline

Open Pipelines in the LangBot WebUI, create a pipeline (or edit the default one) and set AI as follows. If the runner is not listed, install the official runner plugin from Plugins or the LangBot Space marketplace.

3. Create the Discord bot

1. Create a bot with the Discord adapter and enter the Client ID and token.
2. Invite the bot from OAuth2 → URL Generator with the bot scope and Guild Install, granting permission to view channels and send messages.

4. Bind and test

Open the bot, select the pipeline you created, save and make sure the bot is enabled.

Send a message that matches the trigger rules in a server channel, then try a DM from the bot's profile.

Troubleshooting

• Connection refused: http://localhost:7860 only works when Langflow runs on the same host and network namespace as LangBot.
• Gateway login fails: check the current token and that both privileged intents are enabled and saved.
• Discord limits message length, so long streaming replies arrive as several messages.
• Check Monitoring in the WebUI: every message, pipeline run and error is recorded there.

FAQ

Do I need a server with a public IP for Discord?

No. Discord bots connect out to the Discord gateway, so no public webhook URL is required.

Does the Discord bot support streaming replies?

Yes. Enable streaming on the bot; the AI back end must also stream. See the platform feature matrix for details.

Can the same Langflow setup serve other platforms too?

Yes. A pipeline can be bound to many bots, so one configuration can answer on several platforms at once.
