# Connect Dify to KOOK

Source: https://langbot.app/docs/en/recipes/dify/kook

Step-by-step guide to running your Dify app as a KOOK bot with LangBot: Dify setup, bot credentials, networking, testing and troubleshooting.

This recipe puts your Dify 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.

Dify builds chat assistants, Chatflows, Agents and Workflows. LangBot calls the published app through its Service API, so prompts, tools and knowledge stay in Dify.

## What you need

- A running LangBot instance: [LangBot Cloud](https://space.langbot.app/cloud) (no server needed) or a [self-hosted deployment](https://langbot.app/docs/en/deploy/langbot/docker.md) with Docker or `uvx langbot`.
- A Dify 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 Dify

1. Build and **publish** a Chat Assistant (including Chatflow), Agent or Workflow app in Dify.
2. Open the app's **Access API** page and create an API key.
3. For a Workflow app, output the answer under the key `summary`.

## 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](https://space.langbot.app/market).

| Field    | Value                                                                                 |
| -------- | ------------------------------------------------------------------------------------- |
| Runner   | **Dify** (official Dify Agent runner plugin)                                          |
| Base URL | `https://api.dify.ai/v1` for Dify Cloud, or your own Dify address with `/v1` appended |
| API Key  | The key from the app's Access API page                                                |

## 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

- Self-hosted Dify in Docker on the same host: put both stacks on a shared Docker network and use the container address (for example `http://dify-nginx/v1`), not `localhost`.
- Chatflow apps only return what the Answer node outputs.
- 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](https://langbot.app/docs/en/insight/platform-features.md) for what this platform supports. Replies are delivered once the AI back end has finished.

### Can the same Dify setup serve other platforms too?

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