# Telegram (Bot API)

Status: production-ready for bot DMs + groups via grammY. Long polling is the default mode; webhook mode is optional.

## Quick setup

<Steps>
  <Step title="Create the bot token in BotFather">
    Open Telegram and chat with **@BotFather** (confirm the handle is exactly `@BotFather`).

    Run `/newbot`, follow prompts, and save the token.
  </Step>

  <Step title="Configure token and DM policy">
    ```json5 theme={"theme":{"light":"min-light","dark":"min-dark"}}
    {
      channels: {
        telegram: {
          enabled: true,
          botToken: "123:abc",
          dmPolicy: "pairing",
          groups: { "*": { requireMention: true } },
        },
      },
    }
    ```

    Env fallback: `TELEGRAM_BOT_TOKEN=...` (default account only).
  </Step>

  <Step title="Start gateway and approve first DM">
    ```bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
    openclaw gateway
    openclaw pairing list telegram
    openclaw pairing approve telegram <CODE>
    ```

    Pairing codes expire after 1 hour.
  </Step>

  <Step title="Add the bot to a group">
    Add the bot to your group, then set `channels.telegram.groups` and `groupPolicy` to match your access model.
  </Step>
</Steps>

<Note>
  Token resolution order is account-aware. In practice, config values win over env fallback, and `TELEGRAM_BOT_TOKEN` only applies to the default account.
</Note>

## Telegram side settings

<AccordionGroup>
  <Accordion title="Privacy mode and group visibility">
    Telegram bots default to **Privacy Mode**, which limits what group messages they receive.

    If the bot must see all group messages, either:

    * disable privacy mode via `/setprivacy`, or
    * make the bot a group admin.

    When toggling privacy mode, remove + re-add the bot in each group so Telegram applies the change.
  </Accordion>

  <Accordion title="Group permissions">
    Admin status is controlled in Telegram group settings.

    Admin bots receive all group messages, which is useful for always-on group behavior.
  </Accordion>

  <Accordion title="Helpful BotFather toggles">
    * `/setjoingroups` to allow/deny group adds

    * `/setprivacy` for group visibility behavior
  </Accordion>
</AccordionGroup>

## Access control and activation

<Tabs>
  <Tab title="DM policy">
    `channels.telegram.dmPolicy` controls direct message access:

    * `pairing` (default)
    * `allowlist`
    * `open` (requires `allowFrom` to include `"*"`)
    * `disabled`

    `channels.telegram.allowFrom` accepts numeric Telegram user IDs. `telegram:` / `tg:` prefixes are accepted and normalized.
    The onboarding wizard accepts `@username` input and resolves it to numeric IDs.
    If you upgraded and your config contains `@username` allowlist entries, run `openclaw doctor --fix` to resolve them (best-effort; requires a Telegram bot token).

    ### Finding your Telegram user ID

    Safer (no third-party bot):

    1. DM your bot.
    2. Run `openclaw logs --follow`.
    3. Read `from.id`.

    Official Bot API method:

    ```bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
    curl "https://api.telegram.org/bot<bot_token>/getUpdates"
    ```

    Third-party method (less private): `@userinfobot` or `@getidsbot`.
  </Tab>

  <Tab title="Group policy and allowlists">
    There are two independent controls:

    1. **Which groups are allowed** (`channels.telegram.groups`)
       * no `groups` config: all groups allowed
       * `groups` configured: acts as allowlist (explicit IDs or `"*"`)

    2. **Which senders are allowed in groups** (`channels.telegram.groupPolicy`)
       * `open`
       * `allowlist` (default)
       * `disabled`

    `groupAllowFrom` is used for group sender filtering. If not set, Telegram falls back to `allowFrom`.
    `groupAllowFrom` entries must be numeric Telegram user IDs.

    Example: allow any member in one specific group:

    ```json5 theme={"theme":{"light":"min-light","dark":"min-dark"}}
    {
      channels: {
        telegram: {
          groups: {
            "-1001234567890": {
              groupPolicy: "open",
              requireMention: false,
            },
          },
        },
      },
    }
    ```
  </Tab>

  <Tab title="Mention behavior">
    Group replies require mention by default.

    Mention can come from:

    * native `@botusername` mention, or
    * mention patterns in:
      * `agents.list[].groupChat.mentionPatterns`
      * `messages.groupChat.mentionPatterns`

    Session-level command toggles:

    * `/activation always`
    * `/activation mention`

    These update session state only. Use config for persistence.

    Persistent config example:

    ```json5 theme={"theme":{"light":"min-light","dark":"min-dark"}}
    {
      channels: {
        telegram: {
          groups: {
            "*": { requireMention: false },
          },
        },
      },
    }
    ```

    Getting the group chat ID:

    * forward a group message to `@userinfobot` / `@getidsbot`

    * or read `chat.id` from `openclaw logs --follow`

    * or inspect Bot API `getUpdates`
  </Tab>
</Tabs>

## Runtime behavior

* Telegram is owned by the gateway process.
* Routing is deterministic: Telegram inbound replies back to Telegram (the model does not pick channels).
* Inbound messages normalize into the shared channel envelope with reply metadata and media placeholders.
* Group sessions are isolated by group ID. Forum topics append `:topic:<threadId>` to keep topics isolated.
* DM messages can carry `message_thread_id`; OpenClaw routes them with thread-aware session keys and preserves thread ID for replies.
* Long polling uses grammY runner with per-chat/per-thread sequencing. Overall runner sink concurrency uses `agents.defaults.maxConcurrent`.
* Telegram Bot API has no read-receipt support (`sendReadReceipts` does not apply).

## Feature reference

<AccordionGroup>
  <Accordion title="Live stream preview (message edits)">
    OpenClaw can stream partial replies by sending a temporary Telegram message and editing it as text arrives.

    Requirement:

    * `channels.telegram.streamMode` is not `"off"` (default: `"partial"`)

    Modes:

    * `off`: no live preview
    * `partial`: frequent preview updates from partial text
    * `block`: chunked preview updates using `channels.telegram.draftChunk`

    `draftChunk` defaults for `streamMode: "block"`:

    * `minChars: 200`
    * `maxChars: 800`
    * `breakPreference: "paragraph"`

    `maxChars` is clamped by `channels.telegram.textChunkLimit`.

    This works in direct chats and groups/topics.

    For text-only replies, OpenClaw keeps the same preview message and performs a final edit in place (no second message).

    For complex replies (for example media payloads), OpenClaw falls back to normal final delivery and then cleans up the preview message.

    `streamMode` is separate from block streaming. When block streaming is explicitly enabled for Telegram, OpenClaw skips the preview stream to avoid double-streaming.

    Telegram-only reasoning stream:

    * `/reasoning stream` sends reasoning to the live preview while generating

    * final answer is sent without reasoning text
  </Accordion>

  <Accordion title="Formatting and HTML fallback">
    Outbound text uses Telegram `parse_mode: "HTML"`.

    * Markdown-ish text is rendered to Telegram-safe HTML.
    * Raw model HTML is escaped to reduce Telegram parse failures.
    * If Telegram rejects parsed HTML, OpenClaw retries as plain text.

    Link previews are enabled by default and can be disabled with `channels.telegram.linkPreview: false`.
  </Accordion>

  <Accordion title="Native commands and custom commands">
    Telegram command menu registration is handled at startup with `setMyCommands`.

    Native command defaults:

    * `commands.native: "auto"` enables native commands for Telegram

    Add custom command menu entries:

    ```json5 theme={"theme":{"light":"min-light","dark":"min-dark"}}
    {
      channels: {
        telegram: {
          customCommands: [
            { command: "backup", description: "Git backup" },
            { command: "generate", description: "Create an image" },
          ],
        },
      },
    }
    ```

    Rules:

    * names are normalized (strip leading `/`, lowercase)
    * valid pattern: `a-z`, `0-9`, `_`, length `1..32`
    * custom commands cannot override native commands
    * conflicts/duplicates are skipped and logged

    Notes:

    * custom commands are menu entries only; they do not auto-implement behavior
    * plugin/skill commands can still work when typed even if not shown in Telegram menu

    If native commands are disabled, built-ins are removed. Custom/plugin commands may still register if configured.

    Common setup failure:

    * `setMyCommands failed` usually means outbound DNS/HTTPS to `api.telegram.org` is blocked.

    ### Device pairing commands (`device-pair` plugin)

    When the `device-pair` plugin is installed:

    1. `/pair` generates setup code
    2. paste code in iOS app
    3. `/pair approve` approves latest pending request

    More details: [Pairing](/channels/pairing#pair-via-telegram-recommended-for-ios).
  </Accordion>

  <Accordion title="Inline buttons">
    Configure inline keyboard scope:

    ```json5 theme={"theme":{"light":"min-light","dark":"min-dark"}}
    {
      channels: {
        telegram: {
          capabilities: {
            inlineButtons: "allowlist",
          },
        },
      },
    }
    ```

    Per-account override:

    ```json5 theme={"theme":{"light":"min-light","dark":"min-dark"}}
    {
      channels: {
        telegram: {
          accounts: {
            main: {
              capabilities: {
                inlineButtons: "allowlist",
              },
            },
          },
        },
      },
    }
    ```

    Scopes:

    * `off`
    * `dm`
    * `group`
    * `all`
    * `allowlist` (default)

    Legacy `capabilities: ["inlineButtons"]` maps to `inlineButtons: "all"`.

    Message action example:

    ```json5 theme={"theme":{"light":"min-light","dark":"min-dark"}}
    {
      action: "send",
      channel: "telegram",
      to: "123456789",
      message: "Choose an option:",
      buttons: [
        [
          { text: "Yes", callback_data: "yes" },
          { text: "No", callback_data: "no" },
        ],
        [{ text: "Cancel", callback_data: "cancel" }],
      ],
    }
    ```

    Callback clicks are passed to the agent as text:
    `callback_data: <value>`
  </Accordion>

  <Accordion title="Telegram message actions for agents and automation">
    Telegram tool actions include:

    * `sendMessage` (`to`, `content`, optional `mediaUrl`, `replyToMessageId`, `messageThreadId`)
    * `react` (`chatId`, `messageId`, `emoji`)
    * `deleteMessage` (`chatId`, `messageId`)
    * `editMessage` (`chatId`, `messageId`, `content`)

    Channel message actions expose ergonomic aliases (`send`, `react`, `delete`, `edit`, `sticker`, `sticker-search`).

    Gating controls:

    * `channels.telegram.actions.sendMessage`
    * `channels.telegram.actions.editMessage`
    * `channels.telegram.actions.deleteMessage`
    * `channels.telegram.actions.reactions`
    * `channels.telegram.actions.sticker` (default: disabled)

    Reaction removal semantics: [/tools/reactions](/tools/reactions)
  </Accordion>

  <Accordion title="Reply threading tags">
    Telegram supports explicit reply threading tags in generated output:

    * `[[reply_to_current]]` replies to the triggering message
    * `[[reply_to:<id>]]` replies to a specific Telegram message ID

    `channels.telegram.replyToMode` controls handling:

    * `off` (default)
    * `first`
    * `all`

    Note: `off` disables implicit reply threading. Explicit `[[reply_to_*]]` tags are still honored.
  </Accordion>

  <Accordion title="Forum topics and thread behavior">
    Forum supergroups:

    * topic session keys append `:topic:<threadId>`
    * replies and typing target the topic thread
    * topic config path:
      `channels.telegram.groups.<chatId>.topics.<threadId>`

    General topic (`threadId=1`) special-case:

    * message sends omit `message_thread_id` (Telegram rejects `sendMessage(...thread_id=1)`)
    * typing actions still include `message_thread_id`

    Topic inheritance: topic entries inherit group settings unless overridden (`requireMention`, `allowFrom`, `skills`, `systemPrompt`, `enabled`, `groupPolicy`).

    Template context includes:

    * `MessageThreadId`
    * `IsForum`

    DM thread behavior:

    * private chats with `message_thread_id` keep DM routing but use thread-aware session keys/reply targets.
  </Accordion>

  <Accordion title="Audio, video, and stickers">
    ### Audio messages

    Telegram distinguishes voice notes vs audio files.

    * default: audio file behavior
    * tag `[[audio_as_voice]]` in agent reply to force voice-note send

    Message action example:

    ```json5 theme={"theme":{"light":"min-light","dark":"min-dark"}}
    {
      action: "send",
      channel: "telegram",
      to: "123456789",
      media: "https://example.com/voice.ogg",
      asVoice: true,
    }
    ```

    ### Video messages

    Telegram distinguishes video files vs video notes.

    Message action example:

    ```json5 theme={"theme":{"light":"min-light","dark":"min-dark"}}
    {
      action: "send",
      channel: "telegram",
      to: "123456789",
      media: "https://example.com/video.mp4",
      asVideoNote: true,
    }
    ```

    Video notes do not support captions; provided message text is sent separately.

    ### Stickers

    Inbound sticker handling:

    * static WEBP: downloaded and processed (placeholder `<media:sticker>`)
    * animated TGS: skipped
    * video WEBM: skipped

    Sticker context fields:

    * `Sticker.emoji`
    * `Sticker.setName`
    * `Sticker.fileId`
    * `Sticker.fileUniqueId`
    * `Sticker.cachedDescription`

    Sticker cache file:

    * `~/.openclaw/telegram/sticker-cache.json`

    Stickers are described once (when possible) and cached to reduce repeated vision calls.

    Enable sticker actions:

    ```json5 theme={"theme":{"light":"min-light","dark":"min-dark"}}
    {
      channels: {
        telegram: {
          actions: {
            sticker: true,
          },
        },
      },
    }
    ```

    Send sticker action:

    ```json5 theme={"theme":{"light":"min-light","dark":"min-dark"}}
    {
      action: "sticker",
      channel: "telegram",
      to: "123456789",
      fileId: "CAACAgIAAxkBAAI...",
    }
    ```

    Search cached stickers:

    ```json5 theme={"theme":{"light":"min-light","dark":"min-dark"}}
    {
      action: "sticker-search",
      channel: "telegram",
      query: "cat waving",
      limit: 5,
    }
    ```
  </Accordion>

  <Accordion title="Reaction notifications">
    Telegram reactions arrive as `message_reaction` updates (separate from message payloads).

    When enabled, OpenClaw enqueues system events like:

    * `Telegram reaction added: 👍 by Alice (@alice) on msg 42`

    Config:

    * `channels.telegram.reactionNotifications`: `off | own | all` (default: `own`)
    * `channels.telegram.reactionLevel`: `off | ack | minimal | extensive` (default: `minimal`)

    Notes:

    * `own` means user reactions to bot-sent messages only (best-effort via sent-message cache).
    * Telegram does not provide thread IDs in reaction updates.
      * non-forum groups route to group chat session
      * forum groups route to the group general-topic session (`:topic:1`), not the exact originating topic

    `allowed_updates` for polling/webhook include `message_reaction` automatically.
  </Accordion>

  <Accordion title="Ack reactions">
    `ackReaction` sends an acknowledgement emoji while OpenClaw is processing an inbound message.

    Resolution order:

    * `channels.telegram.accounts.<accountId>.ackReaction`
    * `channels.telegram.ackReaction`
    * `messages.ackReaction`
    * agent identity emoji fallback (`agents.list[].identity.emoji`, else "👀")

    Notes:

    * Telegram expects unicode emoji (for example "👀").

    * Use `""` to disable the reaction for a channel or account.
  </Accordion>

  <Accordion title="Config writes from Telegram events and commands">
    Channel config writes are enabled by default (`configWrites !== false`).

    Telegram-triggered writes include:

    * group migration events (`migrate_to_chat_id`) to update `channels.telegram.groups`
    * `/config set` and `/config unset` (requires command enablement)

    Disable:

    ```json5 theme={"theme":{"light":"min-light","dark":"min-dark"}}
    {
      channels: {
        telegram: {
          configWrites: false,
        },
      },
    }
    ```
  </Accordion>

  <Accordion title="Long polling vs webhook">
    Default: long polling.

    Webhook mode:

    * set `channels.telegram.webhookUrl`
    * set `channels.telegram.webhookSecret` (required when webhook URL is set)
    * optional `channels.telegram.webhookPath` (default `/telegram-webhook`)
    * optional `channels.telegram.webhookHost` (default `127.0.0.1`)

    Default local listener for webhook mode binds to `127.0.0.1:8787`.

    If your public endpoint differs, place a reverse proxy in front and point `webhookUrl` at the public URL.
    Set `webhookHost` (for example `0.0.0.0`) when you intentionally need external ingress.
  </Accordion>

  <Accordion title="Limits, retry, and CLI targets">
    * `channels.telegram.textChunkLimit` default is 4000.
    * `channels.telegram.chunkMode="newline"` prefers paragraph boundaries (blank lines) before length splitting.
    * `channels.telegram.mediaMaxMb` (default 5) caps inbound Telegram media download/processing size.
    * `channels.telegram.timeoutSeconds` overrides Telegram API client timeout (if unset, grammY default applies).
    * group context history uses `channels.telegram.historyLimit` or `messages.groupChat.historyLimit` (default 50); `0` disables.
    * DM history controls:
      * `channels.telegram.dmHistoryLimit`
      * `channels.telegram.dms["<user_id>"].historyLimit`
    * outbound Telegram API retries are configurable via `channels.telegram.retry`.

    CLI send target can be numeric chat ID or username:

    ```bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
    openclaw message send --channel telegram --target 123456789 --message "hi"
    openclaw message send --channel telegram --target @name --message "hi"
    ```
  </Accordion>
</AccordionGroup>

## Troubleshooting

<AccordionGroup>
  <Accordion title="Bot does not respond to non mention group messages">
    * If `requireMention=false`, Telegram privacy mode must allow full visibility.
      * BotFather: `/setprivacy` -> Disable
      * then remove + re-add bot to group

    * `openclaw channels status` warns when config expects unmentioned group messages.

    * `openclaw channels status --probe` can check explicit numeric group IDs; wildcard `"*"` cannot be membership-probed.

    * quick session test: `/activation always`.
  </Accordion>

  <Accordion title="Bot not seeing group messages at all">
    * when `channels.telegram.groups` exists, group must be listed (or include `"*"`)

    * verify bot membership in group

    * review logs: `openclaw logs --follow` for skip reasons
  </Accordion>

  <Accordion title="Commands work partially or not at all">
    * authorize your sender identity (pairing and/or numeric `allowFrom`)

    * command authorization still applies even when group policy is `open`

    * `setMyCommands failed` usually indicates DNS/HTTPS reachability issues to `api.telegram.org`
  </Accordion>

  <Accordion title="Polling or network instability">
    * Node 22+ + custom fetch/proxy can trigger immediate abort behavior if AbortSignal types mismatch.
    * Some hosts resolve `api.telegram.org` to IPv6 first; broken IPv6 egress can cause intermittent Telegram API failures.
    * Validate DNS answers:

    ```bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
    dig +short api.telegram.org A
    dig +short api.telegram.org AAAA
    ```
  </Accordion>
</AccordionGroup>
