# Connect Coze to DingTalk

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

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

This recipe puts your Coze 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.

Coze builds agents visually. LangBot calls a Coze bot through the Coze API, so you can reach platforms Coze does not publish to and keep one bot across many channels.

## 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 Coze 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 Coze

1. In the Coze developer console, create a token under **API Management** (coze.com offers Personal Access Tokens; coze.cn also supports service credentials).
2. Publish your agent with the **API** channel selected and copy its `bot_id`.

## 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       | **Coze** (official Coze Agent runner plugin)                             |
| API Key      | The Coze token                                                           |
| Bot ID       | The agent's `bot_id`                                                     |
| API Base URL | `https://api.coze.cn` for coze.cn or `https://api.coze.com` for coze.com |

## 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

- Calls fail: check the token and `bot_id` for extra spaces, that the agent was published with the API channel, and that the base URL matches the Coze site.
- 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 Coze setup serve other platforms too?

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