BlueBubbles (macOS REST)

Scope

Use this page when:

• Setting up BlueBubbles channel
• Troubleshooting webhook pairing
• Configuring iMessage on macOS

Status: bundled plugin that talks to the BlueBubbles macOS server over HTTP. Recommended for iMessage integration due to its richer API and easier setup compared to the legacy imsg channel.

Overview

• Runs on macOS via the BlueBubbles helper app (bluebubbles.app).
• Recommended/tested: macOS Sequoia (15). macOS Tahoe (26) works; edit is currently broken on Tahoe, and group icon updates may report success but not sync.
• Moltbot talks to it through its REST API (GET /api/v1/ping, POST /message/text, POST /chat/:id/*).
• Incoming messages arrive via webhooks; outgoing replies, typing indicators, read receipts, and tapbacks are REST calls.
• Attachments and stickers are ingested as inbound media (and surfaced to the agent when possible).
• Pairing/allowlist works the same way as other channels (/start/pairing etc) with channels.bluebubbles.allowFrom + pairing codes.
• Reactions are surfaced as system events just like Slack/Telegram so agents can “mention” them before replying.
• Advanced features: edit, unsend, reply threading, message effects, group management.

Quick start

1. Install the BlueBubbles server on your Mac (follow the instructions at bluebubbles.app/install).
2. In the BlueBubbles config, enable the web API and set a password.
3. Run moltbot onboard and select BlueBubbles, or configure manually:

   {
     channels: {
       bluebubbles: {
         enabled: true,
         serverUrl: "http://192.168.1.100:1234",
         password: "example-password",
         webhookPath: "/bluebubbles-webhook"
       }
     }
   }
4. Point BlueBubbles webhooks to your gateway (example: https://your-gateway-host:3000/bluebubbles-webhook?password=<password>).
5. Start the gateway; it will register the webhook handler and start pairing.

Onboarding

BlueBubbles is available in the interactive setup wizard:

moltbot onboard

The wizard prompts for:

• Server URL (required): BlueBubbles server address (e.g., http://192.168.1.100:1234)
• Password (required): API password from BlueBubbles Server settings
• Webhook path (optional): Defaults to /bluebubbles-webhook
• DM policy: pairing, allowlist, open, or disabled
• Allow list: Phone numbers, emails, or chat targets

You can also add BlueBubbles via CLI:

moltbot channels add bluebubbles --http-url http://192.168.1.100:1234 --password <password>

Access control (DMs + groups)

DMs:

• Default: channels.bluebubbles.dmPolicy = "pairing".
• Unknown senders receive a pairing code; messages are ignored until approved (codes expire after 1 hour).
• Approve via:
  • moltbot pairing list bluebubbles
  • moltbot pairing approve bluebubbles <CODE>
• Pairing is the default token exchange. Details: Pairing

Groups:

• channels.bluebubbles.groupPolicy = open | allowlist | disabled (default: allowlist).
• channels.bluebubbles.groupAllowFrom controls who can trigger in groups when allowlist is set.

Mention gating (groups)

BlueBubbles supports mention gating for group chats, matching iMessage/WhatsApp behavior:

• Uses agents.list[].groupChat.mentionPatterns (or messages.groupChat.mentionPatterns) to detect mentions.
• When requireMention is enabled for a group, the agent only responds when mentioned.
• Control commands from authorized senders bypass mention gating.

Per-group configuration:

{
  channels: {
    bluebubbles: {
      groupPolicy: "allowlist",
      groupAllowFrom: ["+15555550123"],
      groups: {
        "*": { requireMention: true },  // default for all groups
        "iMessage;-;chat123": { requireMention: false }  // override for specific group
      }
    }
  }
}

Command gating

• Control commands (e.g., /config, /model) require authorization.
• Uses allowFrom and groupAllowFrom to determine command authorization.
• Authorized senders can run control commands even without mentioning in groups.

Typing + read receipts

• Typing indicators: Sent automatically before and during response generation.
• Read receipts: Controlled by channels.bluebubbles.sendReadReceipts (default: true).
• Typing indicators: Moltbot sends typing start events; BlueBubbles clears typing automatically on send or timeout (manual stop via DELETE is unreliable).

{
  channels: {
    bluebubbles: {
      sendReadReceipts: false  // disable read receipts
    }
  }
}

Advanced actions

BlueBubbles supports advanced message actions when enabled in config:

{
  channels: {
    bluebubbles: {
      actions: {
        reactions: true,       // tapbacks (default: true)
        edit: true,            // edit sent messages (macOS 13+, broken on macOS 26 Tahoe)
        unsend: true,          // unsend messages (macOS 13+)
        reply: true,           // reply threading by message GUID
        sendWithEffect: true,  // message effects (slam, loud, etc.)
        renameGroup: true,     // rename group chats
        setGroupIcon: true,    // set group chat icon/photo (flaky on macOS 26 Tahoe)
        addParticipant: true,  // add participants to groups
        removeParticipant: true, // remove participants from groups
        leaveGroup: true,      // leave group chats
        sendAttachment: true   // send attachments/media
      }
    }
  }
}

Available actions:

• react: Add/remove tapback reactions (messageId, emoji, remove)
• edit: Edit a sent message (messageId, text)
• unsend: Unsend a message (messageId)
• reply: Reply to a specific message (messageId, text, to)
• sendWithEffect: Send with iMessage effect (text, to, effectId)
• renameGroup: Rename a group chat (chatGuid, displayName)
• setGroupIcon: Set a group chat’s icon/photo (chatGuid, media) — flaky on macOS 26 Tahoe (API may return success but the icon does not sync).
• addParticipant: Add someone to a group (chatGuid, address)
• removeParticipant: Remove someone from a group (chatGuid, address)
• leaveGroup: Leave a group chat (chatGuid)
• sendAttachment: Send media/files (to, buffer, filename, asVoice)
  • Voice memos: set asVoice: true with MP3 or CAF audio to send as an iMessage voice message. BlueBubbles converts MP3 → CAF when sending voice memos.

Message IDs (short vs full)

Moltbot may surface short message IDs (e.g., 1, 2) to save tokens.

• MessageSid / ReplyToId can be short IDs.
• MessageSidFull / ReplyToIdFull contain the provider full IDs.
• Short IDs are in-memory; they can expire on restart or cache eviction.
• Actions accept short or full messageId, but short IDs will error if no longer available.

Use full IDs for durable automations and storage:

• Templates: {{MessageSidFull}}, {{ReplyToIdFull}}
• Context: MessageSidFull / ReplyToIdFull in inbound payloads

See Configuration for template variables.

Block streaming

Control whether responses are sent as a single message or streamed in blocks:

{
  channels: {
    bluebubbles: {
      blockStreaming: true  // enable block streaming (default behavior)
    }
  }
}

Media + limits

• Inbound attachments are downloaded and stored in the media cache.
• Media cap via channels.bluebubbles.mediaMaxMb (default: 8 MB).
• Outbound text is chunked to channels.bluebubbles.textChunkLimit (default: 4000 chars).

Configuration reference

Related global options:

Addressing / delivery targets

Prefer chat_guid for stable routing:

• chat_guid:iMessage;-;+15555550123 (preferred for groups)
• chat_id:123
• chat_identifier:...
• Direct handles: +15555550123, [email protected]
  • If a direct handle does not have an existing DM chat, Moltbot will create one via POST /api/v1/chat/new. This requires the BlueBubbles Private API to be enabled.

Security

• Webhook requests are authenticated by comparing guid/password query params or headers against channels.bluebubbles.password. Requests from localhost are also accepted.
• Keep the API password and webhook endpoint secret (treat them like credentials).
• Enable HTTPS + firewall rules on the BlueBubbles server if exposing it outside your LAN.

Troubleshooting

• If typing/read events stop working, check the BlueBubbles webhook logs and verify the gateway path matches channels.bluebubbles.webhookPath.
• Pairing codes expire after one hour; use moltbot pairing list bluebubbles and moltbot pairing approve bluebubbles <code>.
• Reactions require the BlueBubbles private API (POST /api/v1/message/react); ensure the server version exposes it.
• Edit/unsend require macOS 13+ and a compatible BlueBubbles server version. On macOS 26 (Tahoe), edit is currently broken due to private API changes.
• Group icon updates can be flaky on macOS 26 (Tahoe): the API may return success but the new icon does not sync.
• Moltbot auto-hides known-broken actions based on the BlueBubbles server’s macOS version. If edit still appears on macOS 26 (Tahoe), disable it manually with channels.bluebubbles.actions.edit=false.
• For status/health info: moltbot status --all or moltbot status --deep.
