Connect n8n to KOOK

This recipe puts your n8n app behind a KOOK bot. LangBot receives messages from KOOK, runs them through a pipeline, and sends the answer back, so you do not write any platform code.

n8n runs the workflow; LangBot handles the chat platform, sessions and delivery and calls your workflow through a webhook 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 n8n account or instance that LangBot can reach over the network.
• A bot created in the KOOK developer center and its Bot Token.

Networking

The KOOK adapter only needs a bot token; LangBot connects out to KOOK.

1. Prepare n8n

1. Start the workflow with a Webhook or On chat message trigger. Set Response Mode to Streaming if you want streamed replies.
2. Answer with an AI Agent node (streaming) or a Respond to Webhook node whose response key matches LangBot's output key.
3. Click Active to enable the workflow and copy its production webhook URL.

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 KOOK bot

1. Create a bot with the KOOK adapter and enter the Bot Token.
2. Grant the bot permissions and invite it to your server.

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 channel the bot can read.

Troubleshooting

• Empty replies: the key in Respond to Webhook must match the output key configured in LangBot.
• The test URL only works while the n8n editor is listening; use the production URL of an active workflow.
• No reply in a channel: check the bot's channel permissions and the pipeline's group trigger rules.
• 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 KOOK?

No. The KOOK adapter only needs a bot token; LangBot connects out to KOOK.

Does the KOOK bot support streaming replies?

Check the platform feature matrix for what this platform supports. Replies are delivered once the AI back end has finished.

Can the same n8n setup serve other platforms too?

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