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 2026.4.25 or above. Run openclaw --version to check. Upgrade with openclaw update.

Run the channel setup wizard

openclaw channels login --channel feishu

Scan the QR code with your Feishu/Lark mobile app to create a Feishu/Lark bot automatically.

After setup completes, restart the gateway to apply the changes

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` or explicitly configured under `groups.<chat_id>`
`"disabled"`	Disable all group messages; explicit `groups.<chat_id>` entries do not override this

Default: allowlist Mention requirement (channels.feishu.requireMention):

true — require @mention (default)
false — respond without @mention
Per-group override: channels.feishu.groups.<chat_id>.requireMention
Broadcast-only @all and @_all are not treated as bot mentions. A message that mentions both @all and the bot directly still counts as a bot mention.

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"],
    },
  },
}

In allowlist mode, you can also admit a group by adding an explicit groups.<chat_id> entry. Explicit entries do not override groupPolicy: "disabled". Wildcard defaults under groups.* configure matching groups, but they do not admit groups by themselves.

{
  channels: {
    feishu: {
      groupPolicy: "allowlist",
      groups: {
        oc_xxx: {
          requireMention: false,
        },
      },
    },
  },
}

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.

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",
          tts: {
            providers: {
              openai: { voice: "shimmer" },
            },
          },
        },
        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. accounts.<id>.tts uses the same shape as messages.tts and deep-merges over global TTS config, so multi-bot Feishu setups can keep shared provider credentials globally while overriding only voice, model, persona, or auto mode per account.

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.

Supported message types

Receive

✅ Text
✅ Rich text (post)
✅ Images
✅ Files
✅ Audio
✅ Video/media
✅ Stickers

Inbound Feishu/Lark audio messages are normalized as media placeholders instead of raw file_key JSON. When tools.media.audio is configured, OpenClaw downloads the voice-note resource and runs shared audio transcription before the agent turn, so the agent receives the spoken transcript. If Feishu includes transcript text directly in the audio payload, that text is used without another ASR call. Without an audio transcription provider, the agent still receives a <media:audio> placeholder plus the saved attachment, not the raw Feishu resource payload.

Send

✅ Text
✅ Images
✅ Files
✅ Audio
✅ Video/media
✅ Interactive cards (including streaming updates)
⚠️ Rich text (post-style formatting; doesn’t support full Feishu/Lark authoring capabilities)

Native Feishu/Lark audio bubbles use the Feishu audio message type and require Ogg/Opus upload media (file_type: "opus"). Existing .opus and .ogg media is sent directly as native audio. MP3/WAV/M4A and other likely audio formats are transcoded to 48kHz Ogg/Opus with ffmpeg only when the reply requests voice delivery (audioAsVoice / message tool asVoice, including TTS voice-note replies). Ordinary MP3 attachments stay regular files. If ffmpeg is missing or conversion fails, OpenClaw falls back to a file attachment and logs the reason.

Threads and replies

✅ Inline replies
✅ Thread replies
✅ Media replies stay thread-aware when replying to a thread message

For groupSessionScope: "group_topic" and "group_topic_sender", native Feishu/Lark topic groups use the event thread_id (omt_*) as the canonical topic session key. Normal group replies that OpenClaw turns into threads keep using the reply root message ID (om_*) so the first turn and follow-up turn stay in the same session.
