# Telegram (Bot API)

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

</CardGroup>

## 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
{
  channels: {
    telegram: {
      enabled: true,
      botToken: "123:abc",
      dmPolicy: "pairing",
      groups: { "*": { requireMention: true } },
    },
  },
}
```

    Env fallback: `TELEGRAM_BOT_TOKEN=...` (default account only).
    Telegram does **not** use `openclaw channels login telegram`; configure token in config/env, then start gateway.

  </Step>

  <Step title="Start gateway and approve first DM">

```bash
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` (requires at least one sender ID in `allowFrom`)
    - `open` (requires `allowFrom` to include `"*"`)
    - `disabled`

    `channels.telegram.allowFrom` accepts numeric Telegram user IDs. `telegram:` / `tg:` prefixes are accepted and normalized.
    `dmPolicy: "allowlist"` with empty `allowFrom` blocks all DMs and is rejected by config validation.
    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).
    If you previously relied on pairing-store allowlist files, `openclaw doctor --fix` can recover entries into `channels.telegram.allowFrom` in allowlist flows (for example when `dmPolicy: "allowlist"` has no explicit IDs yet).

    ### 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
curl "https://api.telegram.org/bot<bot_token>/getUpdates"
```

    Third-party method (less private): `@userinfobot` or `@getidsbot`.

  </Tab>

  <Tab title="Group policy and allowlists">
    Two controls apply together:

    1. **Which groups are allowed** (`channels.telegram.groups`)
       - no `groups` config:
         - with `groupPolicy: "open"`: any group can pass group-ID checks
         - with `groupPolicy: "allowlist"` (default): groups are blocked until you add `groups` entries (or `"*"`)
       - `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 should be numeric Telegram user IDs (`telegram:` / `tg:` prefixes are normalized).
    Non-numeric entries are ignored for sender authorization.
    Security boundary (`2026.2.25+`): group sender auth does **not** inherit DM pairing-store approvals.
    Pairing stays DM-only. For groups, set `groupAllowFrom` or per-group/per-topic `allowFrom`.
    Runtime note: if `channels.telegram` is completely missing, runtime defaults to fail-closed `groupPolicy="allowlist"` unless `channels.defaults.groupPolicy` is explicitly set.

    Example: allow any member in one specific group:

```json5
{
  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
{
  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.streaming` is `off | partial | block | progress` (default: `off`)
    - `progress` maps to `partial` on Telegram (compat with cross-channel naming)
    - legacy `channels.telegram.streamMode` and boolean `streaming` values are auto-mapped

    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.

    Preview streaming 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
{
  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
{
  channels: {
    telegram: {
      capabilities: {
        inlineButtons: "allowlist",
      },
    },
  },
}
```

    Per-account override:

```json5
{
  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
{
  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`)
    - `createForumTopic` (`chatId`, `name`, optional `iconColor`, `iconCustomEmojiId`)

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

    Gating controls:

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

    Note: `edit` and `topic-create` are currently enabled by default and do not have separate `channels.telegram.actions.*` toggles.

    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
{
  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
{
  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
{
  channels: {
    telegram: {
      actions: {
        sticker: true,
      },
    },
  },
}
```

    Send sticker action:

```json5
{
  action: "sticker",
  channel: "telegram",
  to: "123456789",
  fileId: "CAACAgIAAxkBAAI...",
}
```

    Search cached stickers:

```json5
{
  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).
    - Reaction events still respect Telegram access controls (`dmPolicy`, `allowFrom`, `groupPolicy`, `groupAllowFrom`); unauthorized senders are dropped.
    - 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
{
  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`)
    - optional `channels.telegram.webhookPort` (default `8787`)

    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`
    - `channels.telegram.retry` config applies to Telegram send helpers (CLI/tools/actions) for recoverable outbound API errors.

    CLI send target can be numeric chat ID or username:

```bash
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.
    - If logs include `TypeError: fetch failed` or `Network request for 'getUpdates' failed!`, OpenClaw now retries these as recoverable network errors.
    - On VPS hosts with unstable direct egress/TLS, route Telegram API calls through `channels.telegram.proxy`:

```yaml
channels:
  telegram:
    proxy: socks5://user:pass@proxy-host:1080
```

    - Node 22+ defaults to `autoSelectFamily=true` (except WSL2) and `dnsResultOrder=ipv4first`.
    - If your host is WSL2 or explicitly works better with IPv4-only behavior, force family selection:

```yaml
channels:
  telegram:
    network:
      autoSelectFamily: false
```

    - Environment overrides (temporary):
      - `OPENCLAW_TELEGRAM_DISABLE_AUTO_SELECT_FAMILY=1`
      - `OPENCLAW_TELEGRAM_ENABLE_AUTO_SELECT_FAMILY=1`
      - `OPENCLAW_TELEGRAM_DNS_RESULT_ORDER=ipv4first`
    - Validate DNS answers:

```bash
dig +short api.telegram.org A
dig +short api.telegram.org AAAA
```

  </Accordion>

## Telegram config reference pointers

Primary reference:

- `channels.telegram.enabled`: enable/disable channel startup.
- `channels.telegram.botToken`: bot token (BotFather).
- `channels.telegram.tokenFile`: read token from file path.
- `channels.telegram.dmPolicy`: `pairing | allowlist | open | disabled` (default: pairing).
- `channels.telegram.allowFrom`: DM allowlist (numeric Telegram user IDs). `allowlist` requires at least one sender ID. `open` requires `"*"`. `openclaw doctor --fix` can resolve legacy `@username` entries to IDs and can recover allowlist entries from pairing-store files in allowlist migration flows.
- `channels.telegram.defaultTo`: default Telegram target used by CLI `--deliver` when no explicit `--reply-to` is provided.
- `channels.telegram.groupPolicy`: `open | allowlist | disabled` (default: allowlist).
- `channels.telegram.groupAllowFrom`: group sender allowlist (numeric Telegram user IDs). `openclaw doctor --fix` can resolve legacy `@username` entries to IDs. Non-numeric entries are ignored at auth time. Group auth does not use DM pairing-store fallback (`2026.2.25+`).
- Multi-account precedence:
  - `channels.telegram.accounts.default.allowFrom` and `channels.telegram.accounts.default.groupAllowFrom` apply only to the `default` account.
  - Named accounts inherit `channels.telegram.allowFrom` and `channels.telegram.groupAllowFrom` when account-level values are unset.
  - Named accounts do not inherit `channels.telegram.accounts.default.allowFrom` / `groupAllowFrom`.
- `channels.telegram.groups`: per-group defaults + allowlist (use `"*"` for global defaults).
  - `channels.telegram.groups.<id>.groupPolicy`: per-group override for groupPolicy (`open | allowlist | disabled`).
  - `channels.telegram.groups.<id>.requireMention`: mention gating default.
  - `channels.telegram.groups.<id>.skills`: skill filter (omit = all skills, empty = none).
  - `channels.telegram.groups.<id>.allowFrom`: per-group sender allowlist override.
  - `channels.telegram.groups.<id>.systemPrompt`: extra system prompt for the group.
  - `channels.telegram.groups.<id>.enabled`: disable the group when `false`.
  - `channels.telegram.groups.<id>.topics.<threadId>.*`: per-topic overrides (same fields as group).
  - `channels.telegram.groups.<id>.topics.<threadId>.groupPolicy`: per-topic override for groupPolicy (`open | allowlist | disabled`).
  - `channels.telegram.groups.<id>.topics.<threadId>.requireMention`: per-topic mention gating override.
- `channels.telegram.capabilities.inlineButtons`: `off | dm | group | all | allowlist` (default: allowlist).
- `channels.telegram.accounts.<account>.capabilities.inlineButtons`: per-account override.
- `channels.telegram.commands.nativeSkills`: enable/disable Telegram native skills commands.
- `channels.telegram.replyToMode`: `off | first | all` (default: `off`).
- `channels.telegram.textChunkLimit`: outbound chunk size (chars).
- `channels.telegram.chunkMode`: `length` (default) or `newline` to split on blank lines (paragraph boundaries) before length chunking.
- `channels.telegram.linkPreview`: toggle link previews for outbound messages (default: true).
- `channels.telegram.streaming`: `off | partial | block | progress` (live stream preview; default: `off`; `progress` maps to `partial`; `block` is legacy preview mode compatibility).
- `channels.telegram.mediaMaxMb`: inbound Telegram media download/processing cap (MB).
- `channels.telegram.retry`: retry policy for Telegram send helpers (CLI/tools/actions) on recoverable outbound API errors (attempts, minDelayMs, maxDelayMs, jitter).
- `channels.telegram.network.autoSelectFamily`: override Node autoSelectFamily (true=enable, false=disable). Defaults to enabled on Node 22+, with WSL2 defaulting to disabled.
- `channels.telegram.network.dnsResultOrder`: override DNS result order (`ipv4first` or `verbatim`). Defaults to `ipv4first` on Node 22+.
- `channels.telegram.proxy`: proxy URL for Bot API calls (SOCKS/HTTP).
- `channels.telegram.webhookUrl`: enable webhook mode (requires `channels.telegram.webhookSecret`).
- `channels.telegram.webhookSecret`: webhook secret (required when webhookUrl is set).
- `channels.telegram.webhookPath`: local webhook path (default `/telegram-webhook`).
- `channels.telegram.webhookHost`: local webhook bind host (default `127.0.0.1`).
- `channels.telegram.webhookPort`: local webhook bind port (default `8787`).
- `channels.telegram.actions.reactions`: gate Telegram tool reactions.
