Connect Coze to WeCom Intelligent Bot

This recipe puts your Coze app behind a WeCom Intelligent Bot bot. LangBot receives messages from WeCom Intelligent Bot, 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 WeCom intelligent bot in long connection API mode: its BotID and long-connection Secret. One-click setup can fill both.

Networking

Long connection mode needs no public callback URL. The alternative callback-URL mode does, and the two modes cannot be used at the same time.

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 WeCom Intelligent Bot bot

1. Create a bot with the WeCom Intelligent Bot adapter and use One-Click Setup, or create the bot in WeCom, switch its API mode to long connection and enter the BotID and Secret.
2. Set the bot's visibility scope so the right people can use it, then save and enable.

4. Bind and test

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

Find the bot in the WeCom client, chat with it directly, then add it to a group chat 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.
• The long-connection Secret differs from the callback Token/EncodingAESKey. Switching the API mode to callback URL invalidates existing long connections.
• 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 WeCom Intelligent Bot?

No. Long connection mode needs no public callback URL. The alternative callback-URL mode does, and the two modes cannot be used at the same time.

Does the WeCom Intelligent Bot bot support streaming replies?

Yes. Enable streaming on the bot; the AI back end must also stream. See the platform feature matrix 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.
