# Telegram (Bot API)
2026-01-07 00:25:16 +01:00
Status: production-ready for bot DMs + groups via grammY. Long-polling by default; webhook optional.
2026-01-11 02:40:28 +01:00
## Quick setup (beginner)
1) Create a bot with ** @BotFather ** and copy the token.
2) Set the token:
- Env: `TELEGRAM_BOT_TOKEN=...`
- Or config: `telegram.botToken: "..."` .
3) Start the gateway.
4) DM access is pairing by default; approve the pairing code on first contact.
Minimal config:
```json5
{
telegram: {
enabled: true,
botToken: "123:abc",
dmPolicy: "pairing"
}
}
```
2026-01-07 00:25:16 +01:00
## What it is
- A Telegram Bot API provider owned by the Gateway.
- Deterministic routing: replies go back to Telegram; the model never chooses providers.
2026-01-11 02:52:50 +00:00
- DMs share the agent's main session; groups stay isolated (`agent:<agentId>:telegram:group:<chatId>` ).
2026-01-07 00:25:16 +01:00
## Setup (fast path)
2026-01-08 09:33:35 +00:00
### 1) Create a bot token (BotFather)
1) Open Telegram and chat with ** @BotFather **.
2) Run `/newbot` , then follow the prompts (name + username ending in `bot` ).
3) Copy the token and store it safely.
Optional BotFather settings:
- `/setjoingroups` — allow/deny adding the bot to groups.
- `/setprivacy` — control whether the bot sees all group messages.
### 2) Configure the token (env or config)
Example:
2026-01-07 00:25:16 +01:00
2025-12-07 22:46:02 +01:00
```json5
{
telegram: {
2025-12-26 16:54:53 +00:00
enabled: true,
2025-12-07 22:46:02 +01:00
botToken: "123:abc",
2026-01-07 00:25:16 +01:00
dmPolicy: "pairing",
groups: { "*": { requireMention: true } }
2025-12-07 22:46:02 +01:00
}
}
```
2026-01-07 00:25:16 +01:00
2026-01-11 02:40:28 +01:00
Env option: `TELEGRAM_BOT_TOKEN=...` (works for the default account).
2026-01-08 01:18:37 +01:00
Multi-account support: use `telegram.accounts` with per-account tokens and optional `name` . See [`gateway/configuration` ](/gateway/configuration#telegramaccounts--discordaccounts--slackaccounts--signalaccounts--imessageaccounts ) for the shared pattern.
2026-01-11 02:40:28 +01:00
3) Start the gateway. Telegram starts when a token is resolved (env or config).
2026-01-07 00:25:16 +01:00
4) DM access defaults to pairing. Approve the code when the bot is first contacted.
2026-01-08 09:33:35 +00:00
5) For groups: add the bot, decide privacy/admin behavior (below), then set `telegram.groups` to control mention gating + allowlists.
## Token + privacy + permissions (Telegram side)
### Token creation (BotFather)
- `/newbot` creates the bot and returns the token (keep it secret).
- If a token leaks, revoke/regenerate it via @BotFather and update your config.
### Group message visibility (Privacy Mode)
Telegram bots default to **Privacy Mode** , which limits which group messages they receive.
If your bot must see *all* group messages, you have two options:
- Disable privacy mode with `/setprivacy` **or**
- Add the bot as a group **admin** (admin bots receive all messages).
**Note:** When you toggle privacy mode, Telegram requires removing + re‑ adding the bot
to each group for the change to take effect.
### Group permissions (admin rights)
Admin status is set inside the group (Telegram UI). Admin bots always receive all
group messages, so use admin if you need full visibility.
2026-01-07 00:25:16 +01:00
## How it works (behavior)
- Inbound messages are normalized into the shared provider envelope with reply context and media placeholders.
2026-01-09 12:44:23 +00:00
- Group replies require a mention by default (native @mention or `agents.list[].groupChat.mentionPatterns` / `messages.groupChat.mentionPatterns` ).
- Multi-agent override: set per-agent patterns on `agents.list[].groupChat.mentionPatterns` .
2026-01-07 00:25:16 +01:00
- Replies always route back to the same Telegram chat.
2026-01-09 12:44:23 +00:00
- Long-polling uses grammY runner with per-chat sequencing; overall concurrency is capped by `agents.defaults.maxConcurrent` .
2026-01-07 00:25:16 +01:00
2026-01-08 02:34:32 +01:00
## Formatting (Telegram HTML)
- Outbound Telegram text uses `parse_mode: "HTML"` (Telegram’ s supported tag subset).
- Markdown-ish input is rendered into **Telegram-safe HTML** (bold/italic/strike/code/links); block elements are flattened to text with newlines/bullets.
- Raw HTML from models is escaped to avoid Telegram parse errors.
- If Telegram rejects the HTML payload, Clawdbot retries the same message as plain text.
2026-01-08 04:02:04 +01:00
## Limits
- Outbound text is chunked to `telegram.textChunkLimit` (default 4000).
- Media downloads/uploads are capped by `telegram.mediaMaxMb` (default 5).
2026-01-10 18:53:38 +01:00
- Group history context uses `telegram.historyLimit` (or `telegram.accounts.*.historyLimit` ), falling back to `messages.groupChat.historyLimit` . Set `0` to disable (default 50).
2026-01-08 04:02:04 +01:00
2026-01-07 08:54:58 +00:00
## Group activation modes
2026-01-09 12:44:23 +00:00
By default, the bot only responds to mentions in groups (`@botname` or patterns in `agents.list[].groupChat.mentionPatterns` ). To change this behavior:
2026-01-07 08:54:58 +00:00
### Via config (recommended)
```json5
{
telegram: {
groups: {
"-1001234567890": { requireMention: false } // always respond in this group
}
}
}
```
**Important:** Setting `telegram.groups` creates an **allowlist** - only listed groups (or `"*"` ) will be accepted.
To allow all groups with always-respond:
```json5
{
telegram: {
groups: {
"*": { requireMention: false } // all groups, always respond
}
}
}
```
To keep mention-only for all groups (default behavior):
```json5
{
telegram: {
groups: {
"*": { requireMention: true } // or omit groups entirely
}
}
}
```
### Via command (session-level)
Send in the group:
- `/activation always` - respond to all messages
- `/activation mention` - require mentions (default)
**Note:** Commands update session state only. For persistent behavior across restarts, use config.
### Getting the group chat ID
Forward any message from the group to `@userinfobot` or `@getidsbot` on Telegram to see the chat ID (negative number like `-1001234567890` ).
2026-01-11 03:57:44 +01:00
**Tip:** For your own user ID, DM the bot and it will reply with your user ID (pairing message), or use `/whoami` once commands are enabled.
2026-01-10 14:51:51 +01:00
**Privacy note:** `@userinfobot` is a third-party bot. If you prefer, use gateway logs (`clawdbot logs` ) or Telegram developer tools to find user/chat IDs.
2026-01-07 02:10:56 +00:00
## Topics (forum supergroups)
Telegram forum topics include a `message_thread_id` per message. Clawdbot:
- Appends `:topic:<threadId>` to the Telegram group session key so each topic is isolated.
- Sends typing indicators and replies with `message_thread_id` so responses stay in the topic.
- Exposes `MessageThreadId` + `IsForum` in template context for routing/templating.
2026-01-07 11:23:09 +01:00
- Topic-specific configuration is available under `telegram.groups.<chatId>.topics.<threadId>` (skills, allowlists, auto-reply, system prompts, disable).
2026-01-07 02:10:56 +00:00
2026-01-11 02:44:32 +00:00
Private chats can include `message_thread_id` in some edge cases. Clawdbot keeps the DM session key unchanged, but still uses the thread id for replies/draft streaming when it is present.
2026-01-07 11:08:11 +01:00
2026-01-07 00:25:16 +01:00
## Access control (DMs + groups)
2026-01-07 08:54:58 +00:00
### DM access
2026-01-07 05:06:04 +01:00
- Default: `telegram.dmPolicy = "pairing"` . Unknown senders receive a pairing code; messages are ignored until approved (codes expire after 1 hour).
2026-01-07 00:25:16 +01:00
- Approve via:
2026-01-10 16:36:43 +01:00
- `clawdbot pairing list telegram`
- `clawdbot pairing approve telegram <CODE>`
2026-01-07 02:04:02 +01:00
- Pairing is the default token exchange used for Telegram DMs. Details: [Pairing ](/start/pairing )
2026-01-11 03:57:44 +01:00
- `telegram.allowFrom` accepts numeric user IDs (recommended) or `@username` entries.
2026-01-07 00:25:16 +01:00
2026-01-07 08:54:58 +00:00
### Group access
Two independent controls:
**1. Which groups are allowed** (group allowlist via `telegram.groups` ):
- No `groups` config = all groups allowed
- With `groups` config = only listed groups or `"*"` are allowed
- Example: `"groups": { "-1001234567890": {}, "*": {} }` allows all groups
**2. Which senders are allowed** (sender filtering via `telegram.groupPolicy` ):
- `"open"` (default) = all senders in allowed groups can message
- `"allowlist"` = only senders in `telegram.groupAllowFrom` can message
- `"disabled"` = no group messages accepted at all
Most users want: `groupPolicy: "open"` + specific groups listed in `telegram.groups`
2026-01-07 00:25:16 +01:00
## Long-polling vs webhook
- Default: long-polling (no public URL required).
- Webhook mode: set `telegram.webhookUrl` (optionally `telegram.webhookSecret` + `telegram.webhookPath` ).
- The local listener binds to `0.0.0.0:8787` and serves `POST /telegram-webhook` by default.
- If your public URL is different, use a reverse proxy and point `telegram.webhookUrl` at the public endpoint.
## Reply threading
Telegram supports optional threaded replies via tags:
- `[[reply_to_current]]` -- reply to the triggering message.
- `[[reply_to:<id>]]` -- reply to a specific message id.
Controlled by `telegram.replyToMode` :
2026-01-08 00:50:29 +00:00
- `first` (default), `all` , `off` .
2026-01-07 00:25:16 +01:00
2026-01-08 03:13:54 +00:00
## Audio messages (voice vs file)
Telegram distinguishes **voice notes** (round bubble) from **audio files** (metadata card).
Clawdbot defaults to audio files for backward compatibility.
To force a voice note bubble in agent replies, include this tag anywhere in the reply:
- `[[audio_as_voice]]` — send audio as a voice note instead of a file.
The tag is stripped from the delivered text. Other providers ignore this tag.
2026-01-07 11:08:11 +01:00
## Streaming (drafts)
Telegram can stream **draft bubbles** while the agent is generating a response.
Clawdbot uses Bot API `sendMessageDraft` (not real messages) and then sends the
final reply as a normal message.
Requirements (Telegram Bot API 9.3+):
- **Private chats with topics enabled** (forum topic mode for the bot).
- Incoming messages must include `message_thread_id` (private topic thread).
- Streaming is ignored for groups/supergroups/channels.
Config:
- `telegram.streamMode: "off" | "partial" | "block"` (default: `partial` )
- `partial` : update the draft bubble with the latest streaming text.
- `block` : update the draft bubble in larger blocks (chunked).
- `off` : disable draft streaming.
2026-01-10 18:30:06 +01:00
- Optional (only for `streamMode: "block"` ):
- `telegram.draftChunk: { minChars?, maxChars?, breakPreference? }`
- defaults: `minChars: 200` , `maxChars: 800` , `breakPreference: "paragraph"` (clamped to `telegram.textChunkLimit` ).
2026-01-07 11:08:11 +01:00
2026-01-09 22:40:58 +01:00
Note: draft streaming is separate from **block streaming** (provider messages).
Block streaming is off by default and requires `telegram.blockStreaming: true`
if you want early Telegram messages instead of draft updates.
2026-01-07 11:08:11 +01:00
Reasoning stream (Telegram only):
- `/reasoning stream` streams reasoning into the draft bubble while the reply is
generating, then sends the final answer without reasoning.
- If `telegram.streamMode` is `off` , reasoning stream is disabled.
2026-01-07 17:15:53 +01:00
More context: [Streaming + chunking ](/concepts/streaming ).
2026-01-07 11:08:11 +01:00
2026-01-07 17:48:19 +00:00
## Retry policy
Outbound Telegram API calls retry on transient network/429 errors with exponential backoff and jitter. Configure via `telegram.retry` . See [Retry policy ](/concepts/retry ).
2026-01-08 00:50:29 +00:00
## Agent tool (messages + reactions)
- Tool: `telegram` with `sendMessage` action (`to` , `content` , optional `mediaUrl` , `replyToMessageId` , `messageThreadId` ).
2026-01-07 04:10:13 +01:00
- Tool: `telegram` with `react` action (`chatId` , `messageId` , `emoji` ).
2026-01-07 04:24:11 +01:00
- Reaction removal semantics: see [/tools/reactions ](/tools/reactions ).
2026-01-08 00:50:29 +00:00
- Tool gating: `telegram.actions.reactions` and `telegram.actions.sendMessage` (default: enabled).
2026-01-07 04:10:13 +01:00
2026-01-07 00:25:16 +01:00
## Delivery targets (CLI/cron)
- Use a chat id (`123456789` ) or a username (`@name` ) as the target.
2026-01-09 08:59:54 +01:00
- Example: `clawdbot message send --provider telegram --to 123456789 --message "hi"` .
2026-01-07 00:25:16 +01:00
2026-01-07 08:54:58 +00:00
## Troubleshooting
2026-01-08 23:14:11 +01:00
**Bot doesn’ t respond to non-mention messages in a group:**
- If you set `telegram.groups.*.requireMention=false` , Telegram’ s Bot API **privacy mode** must be disabled.
- BotFather: `/setprivacy` → **Disable** (then remove + re-add the bot to the group)
- `clawdbot providers status` shows a warning when config expects unmentioned group messages.
2026-01-08 23:48:07 +01:00
- `clawdbot providers status --probe` can additionally check membership for explicit numeric group IDs (it can’ t audit wildcard `"*"` rules).
2026-01-08 23:14:11 +01:00
- Quick test: `/activation always` (session-only; use config for persistence)
2026-01-07 08:54:58 +00:00
**Bot not seeing group messages at all:**
- If `telegram.groups` is set, the group must be listed or use `"*"`
- Check Privacy Settings in @BotFather → "Group Privacy" should be **OFF**
- Verify bot is actually a member (not just an admin with no read access)
2026-01-08 06:48:28 +00:00
- Check gateway logs: `clawdbot logs --follow` (look for "skipping group message")
2026-01-07 08:54:58 +00:00
**Bot responds to mentions but not `/activation always` :**
- The `/activation` command updates session state but doesn't persist to config
- For persistent behavior, add group to `telegram.groups` with `requireMention: false`
**Commands like `/status` don't work:**
- Make sure your Telegram user ID is authorized (via pairing or `telegram.allowFrom` )
- Commands require authorization even in groups with `groupPolicy: "open"`
