Set up Hermes Agent as a DingTalk chatbot

DingTalk Setup

Hermes Agent integrates with DingTalk (钉钉) as a chatbot, letting you chat with your AI assistant through direct messages or group chats. The bot connects via DingTalk’s Stream Mode — a long-lived WebSocket connection that requires no public URL or webhook server — and replies using markdown-formatted messages through DingTalk’s session webhook API.

Before setup, here’s the part most people want to know: how Hermes behaves once it’s in your DingTalk workspace.

How Hermes Behaves

ContextBehavior
DMs (1:1 chat)Hermes responds to every message. No @mention needed. Each DM has its own session.
Group chatsHermes responds when you @mention it. Without a mention, Hermes ignores the message.
Shared groups with multiple usersBy default, Hermes isolates session history per user inside the group. Two people talking in the same group do not share one transcript unless you explicitly disable that.

Session Model in DingTalk

By default:

This is controlled by config.yaml:

group_sessions_per_user: true

Set it to false only if you explicitly want one shared conversation for the entire group:

group_sessions_per_user: false

This guide walks you through the full setup process — from creating your DingTalk bot to sending your first message.

Prerequisites

Install the required Python packages:

pip install "hermes-agent[dingtalk]"

Or individually:

pip install dingtalk-stream httpx alibabacloud-dingtalk

Step 1: Create a DingTalk App

  1. Go to the DingTalk Developer Console.
  2. Log in with your DingTalk admin account.
  3. Click Application Development → Custom Apps → Create App via H5 Micro-App (or Robot depending on your console version).
  4. Fill in:
    • App Name: e.g., Hermes Agent
    • Description: optional
  5. After creating, navigate to Credentials & Basic Info to find your Client ID (AppKey) and Client Secret (AppSecret). Copy both.

Warning The Client Secret is only displayed once when you create the app. If you lose it, you’ll need to regenerate it. Never share these credentials publicly or commit them to Git.

Step 2: Enable the Robot Capability

  1. In your app’s settings page, go to Add Capability → Robot.
  2. Enable the robot capability.
  3. Under Message Reception Mode, select Stream Mode (recommended — no public URL needed).

Tip Stream Mode is the recommended setup. It uses a long-lived WebSocket connection initiated from your machine, so you don’t need a public IP, domain name, or webhook endpoint. This works behind NAT, firewalls, and on local machines.

Step 3: Find Your DingTalk User ID

Hermes Agent uses your DingTalk User ID to control who can interact with the bot. DingTalk User IDs are alphanumeric strings set by your organization’s admin.

To find yours:

  1. Ask your DingTalk organization admin — User IDs are configured in the DingTalk admin console under Contacts → Members.
  2. Alternatively, the bot logs the sender_id for each incoming message. Start the gateway, send the bot a message, then check the logs for your ID.

Step 4: Configure Hermes Agent

Run the guided setup command:

hermes gateway setup

Select DingTalk when prompted. The setup wizard can authorize via one of two paths:

Note: openClaw branding disclosure Because DingTalk’s verification_uri_complete is hardcoded to the openClaw identity at the API layer, the QR currently authorizes under an openClaw source string until Alibaba / DingTalk-Real-AI registers a Hermes-specific template server-side. This is purely how DingTalk presents the consent screen — the bot you create is fully yours and private to your tenant.

Option B: Manual Configuration

Add the following to your ~/.hermes/.env file:

# Required
DINGTALK_CLIENT_ID=your-app-key
DINGTALK_CLIENT_SECRET=your-app-secret

# Security: restrict who can interact with the bot
DINGTALK_ALLOWED_USERS=user-id-1

# Multiple allowed users (comma-separated)
# DINGTALK_ALLOWED_USERS=user-id-1,user-id-2

Optional behavior settings in ~/.hermes/config.yaml:

group_sessions_per_user: true

Start the Gateway

Once configured, start the DingTalk gateway:

hermes gateway

The bot should connect to DingTalk’s Stream Mode within a few seconds. Send it a message — either a DM or in a group where it’s been added — to test.

Tip You can run hermes gateway in the background or as a systemd service for persistent operation. See the deployment docs for details.

Features

AI Cards

Hermes can reply using DingTalk AI Cards instead of plain markdown messages. Cards provide a richer, more structured display and support streaming updates as the agent generates its response.

To enable AI Cards, configure a card template ID in config.yaml:

platforms:
  dingtalk:
    enabled: true
    extra:
      card_template_id: "your-card-template-id"

You can find your card template ID in the DingTalk Developer Console under your app’s AI Card settings. When AI Cards are enabled, all replies are sent as cards with streaming text updates.

Emoji Reactions

Hermes automatically adds emoji reactions to your messages to show processing status:

These reactions work in both DMs and group chats.

Display Settings

You can customize DingTalk’s display behavior independently from other platforms:

display:
  platforms:
    dingtalk:
      show_reasoning: false   # Show model reasoning/thinking in replies
      streaming: true         # Enable streaming responses (works with AI Cards)
      tool_progress: all      # Show tool execution progress (all/new/off)
      interim_assistant_messages: true  # Show intermediate commentary messages

To disable tool progress and intermediate messages for a cleaner experience:

display:
  platforms:
    dingtalk:
      tool_progress: off
      interim_assistant_messages: false

Troubleshooting

Bot is not responding to messages

Cause: The robot capability isn’t enabled, or DINGTALK_ALLOWED_USERS doesn’t include your User ID.

Fix: Verify the robot capability is enabled in your app settings and that Stream Mode is selected. Check that your User ID is in DINGTALK_ALLOWED_USERS. Restart the gateway.

“dingtalk-stream not installed” error

Cause: The dingtalk-stream Python package is not installed.

Fix: Install it:

pip install dingtalk-stream httpx

“DINGTALK_CLIENT_ID and DINGTALK_CLIENT_SECRET required”

Cause: The credentials aren’t set in your environment or .env file.

Fix: Verify DINGTALK_CLIENT_ID and DINGTALK_CLIENT_SECRET are set correctly in ~/.hermes/.env. The Client ID is your AppKey, and the Client Secret is your AppSecret from the DingTalk Developer Console.

Stream disconnects / reconnection loops

Cause: Network instability, DingTalk platform maintenance, or credential issues.

Fix: The adapter automatically reconnects with exponential backoff (2s → 5s → 10s → 30s → 60s). Check that your credentials are valid and your app hasn’t been deactivated. Verify your network allows outbound WebSocket connections.

Bot is offline

Cause: The Hermes gateway isn’t running, or it failed to connect.

Fix: Check that hermes gateway is running. Look at the terminal output for error messages. Common issues: wrong credentials, app deactivated, dingtalk-stream or httpx not installed.

“No session_webhook available”

Cause: The bot tried to reply but doesn’t have a session webhook URL. This typically happens if the webhook expired or the bot was restarted between receiving the message and sending the reply.

Fix: Send a new message to the bot — each incoming message provides a fresh session webhook for replies. This is a normal DingTalk limitation; the bot can only reply to messages it has received recently.

Security

Warning Always set DINGTALK_ALLOWED_USERS to restrict who can interact with the bot. Without it, the gateway denies all users by default as a safety measure. Only add User IDs of people you trust — authorized users have full access to the agent’s capabilities, including tool use and system access.
