Feishu

Feishu / Lark

Feishu/Lark is an all-in-one collaboration platform where teams chat, share documents, manage calendars, and get work done together.

Status: production-ready for bot DMs + group chats. WebSocket is the default mode; webhook mode is optional.

Quick start

Requires OpenClaw 2026.4.10 or above. Run openclaw --version to check. Upgrade with openclaw update.

```bash openclaw channels login --channel feishu ``` Scan the QR code with your Feishu/Lark mobile app to create a Feishu/Lark bot automatically. ```bash openclaw gateway restart ```

Access control

Direct messages

Configure dmPolicy to control who can DM the bot:

"pairing" — unknown users receive a pairing code; approve via CLI
"allowlist" — only users listed in allowFrom can chat (default: bot owner only)
"open" — allow all users
"disabled" — disable all DMs

Approve a pairing request:

openclaw pairing list feishu
openclaw pairing approve feishu <CODE>

Group chats

Group policy (channels.feishu.groupPolicy):

Value	Behavior
`"open"`	Respond to all messages in groups
`"allowlist"`	Only respond to groups in `groupAllowFrom`
`"disabled"`	Disable all group messages

Default: allowlist

Mention requirement (channels.feishu.requireMention):

true — require @mention (default)
false — respond without @mention
Per-group override: channels.feishu.groups.<chat_id>.requireMention

Group configuration examples

Allow all groups, no @mention required

{
  channels: {
    feishu: {
      groupPolicy: "open",
    },
  },
}

Allow all groups, still require @mention

{
  channels: {
    feishu: {
      groupPolicy: "open",
      requireMention: true,
    },
  },
}

Allow specific groups only

{
  channels: {
    feishu: {
      groupPolicy: "allowlist",
      // Group IDs look like: oc_xxx
      groupAllowFrom: ["oc_xxx", "oc_yyy"],
    },
  },
}

Restrict senders within a group

{
  channels: {
    feishu: {
      groupPolicy: "allowlist",
      groupAllowFrom: ["oc_xxx"],
      groups: {
        oc_xxx: {
          // User open_ids look like: ou_xxx
          allowFrom: ["ou_user1", "ou_user2"],
        },
      },
    },
  },
}

Get group/user IDs

Group IDs (`chat_id`, format: `oc_xxx`)

Open the group in Feishu/Lark, click the menu icon in the top-right corner, and go to Settings. The group ID (chat_id) is listed on the settings page.

Get Group ID

User IDs (`open_id`, format: `ou_xxx`)

Start the gateway, send a DM to the bot, then check the logs:

openclaw logs --follow

Look for open_id in the log output. You can also check pending pairing requests:

openclaw pairing list feishu

Common commands

Command	Description
`/status`	Show bot status
`/reset`	Reset the current session
`/model`	Show or switch the AI model

Feishu/Lark does not support native slash-command menus, so send these as plain text messages.

Troubleshooting

Bot does not respond in group chats

Ensure the bot is added to the group
Ensure you @mention the bot (required by default)
Verify groupPolicy is not "disabled"
Check logs: openclaw logs --follow

Bot does not receive messages

Ensure the bot is published and approved in Feishu Open Platform / Lark Developer
Ensure event subscription includes im.message.receive_v1
Ensure persistent connection (WebSocket) is selected
Ensure all required permission scopes are granted
Ensure the gateway is running: openclaw gateway status
Check logs: openclaw logs --follow

App Secret leaked

Reset the App Secret in Feishu Open Platform / Lark Developer
Update the value in your config
Restart the gateway: openclaw gateway restart

Advanced configuration

Multiple accounts

{
  channels: {
    feishu: {
      defaultAccount: "main",
      accounts: {
        main: {
          appId: "cli_xxx",
          appSecret: "xxx",
          name: "Primary bot",
        },
        backup: {
          appId: "cli_yyy",
          appSecret: "yyy",
          name: "Backup bot",
          enabled: false,
        },
      },
    },
  },
}

defaultAccount controls which account is used when outbound APIs do not specify an accountId.

Message limits

textChunkLimit — outbound text chunk size (default: 2000 chars)
mediaMaxMb — media upload/download limit (default: 30 MB)

Streaming

Feishu/Lark supports streaming replies via interactive cards. When enabled, the bot updates the card in real time as it generates text.

{
  channels: {
    feishu: {
      streaming: true, // enable streaming card output (default: true)
      blockStreaming: true, // enable block-level streaming (default: true)
    },
  },
}

Set streaming: false to send the complete reply in one message.

Quota optimization

Reduce the number of Feishu/Lark API calls with two optional flags:

typingIndicator (default true): set false to skip typing reaction calls
resolveSenderNames (default true): set false to skip sender profile lookups

{
  channels: {
    feishu: {
      typingIndicator: false,
      resolveSenderNames: false,
    },
  },
}

ACP sessions

Feishu/Lark supports ACP for DMs and group thread messages. Feishu/Lark ACP is text-command driven — there are no native slash-command menus, so use /acp ... messages directly in the conversation.

Persistent ACP binding

{
  agents: {
    list: [
      {
        id: "codex",
        runtime: {
          type: "acp",
          acp: {
            agent: "codex",
            backend: "acpx",
            mode: "persistent",
            cwd: "/workspace/openclaw",
          },
        },
      },
    ],
  },
  bindings: [
    {
      type: "acp",
      agentId: "codex",
      match: {
        channel: "feishu",
        accountId: "default",
        peer: { kind: "direct", id: "ou_1234567890" },
      },
    },
    {
      type: "acp",
      agentId: "codex",
      match: {
        channel: "feishu",
        accountId: "default",
        peer: { kind: "group", id: "oc_group_chat:topic:om_topic_root" },
      },
      acp: { label: "codex-feishu-topic" },
    },
  ],
}

Spawn ACP from chat

In a Feishu/Lark DM or thread:

/acp spawn codex --thread here

--thread here works for DMs and Feishu/Lark thread messages. Follow-up messages in the bound conversation route directly to that ACP session.

Multi-agent routing

Use bindings to route Feishu/Lark DMs or groups to different agents.

{
  agents: {
    list: [
      { id: "main" },
      { id: "agent-a", workspace: "/home/user/agent-a" },
      { id: "agent-b", workspace: "/home/user/agent-b" },
    ],
  },
  bindings: [
    {
      agentId: "agent-a",
      match: {
        channel: "feishu",
        peer: { kind: "direct", id: "ou_xxx" },
      },
    },
    {
      agentId: "agent-b",
      match: {
        channel: "feishu",
        peer: { kind: "group", id: "oc_zzz" },
      },
    },
  ],
}

Routing fields:

match.channel: "feishu"
match.peer.kind: "direct" (DM) or "group" (group chat)
match.peer.id: user Open ID (ou_xxx) or group ID (oc_xxx)

See Get group/user IDs for lookup tips.
