Connect Coze to DingTalk

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 (no server needed) or a self-hosted deployment 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.

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

Does the DingTalk bot support streaming replies?
