# Connect n8n to DingTalk

Source: https://langbot.app/docs/en/recipes/n8n/dingtalk

Step-by-step guide to running your n8n app as a DingTalk bot with LangBot: n8n setup, bot credentials, networking, testing and troubleshooting.

This recipe puts your n8n app behind a DingTalk bot. LangBot receives messages from DingTalk, 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](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 n8n account or instance that LangBot can reach over the network.
- A DingTalk app robot (**Client ID** and **Client Secret**). The one-click setup fills both after you authorize on your phone.

## Networking

In Stream Mode LangBot connects out to DingTalk, so no public callback URL is needed.

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

| Field               | Value                                                      |
| ------------------- | ---------------------------------------------------------- |
| Runner              | **n8n** (official n8n workflow runner plugin)              |
| Webhook URL         | The workflow's production webhook URL                      |
| Authentication Type | None, Basic Auth, JWT or Header, matching the trigger node |

## 3. Create the DingTalk bot

1. Create a bot with the **DingTalk** adapter and use **One-Click Setup**, or create the robot manually and enter its credentials.
2. Use **Stream Mode** for event delivery. For streaming replies, import LangBot's `dingtalk_stream_card.json` card template, enable **Use Card Replies** and paste the Card Template ID.

## 4. Bind and test

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

Message the robot directly, then add it to a group and @mention it.

## 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.
- Replies arrive as plain text instead of streaming: the card template is not imported or **Use Card Replies** is off.
- Messages do not arrive: publish the app version and check that Stream Mode is selected under event subscriptions.
- 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 DingTalk?

No. In Stream Mode LangBot connects out to DingTalk, so no public callback URL is needed.

### Does the DingTalk bot support streaming replies?

Yes. Enable streaming on the bot; the AI back end must also stream. See the [platform feature matrix](https://langbot.app/docs/en/insight/platform-features.md) for details.

### 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.
