nagents-channel-telegram-bot

An installable, typed Telegram Bot API connector for the public Nagents Channel API, using direct aiohttp requests and long polling. Python 3.11+; MIT licensed.

Session routing belongs to the application hosting the connector:

• Standalone Agent.listen(session_id=...) feeds all attached channels and Telegram chats into that one shared Agent session.
• The web channel host defaults each (connection name, chat ID) to its own persisted root session and supports explicit reattachment to an existing one. Threads remain routing metadata, not separate sessions.

The connector supplies events, discovery metadata, command parsing and typing indicators. It does not access a session database or choose bindings itself.

Install

python -m venv .venv
source .venv/bin/activate  # Windows: .venv\Scripts\activate
python -m pip install 'nagents>=0.6.0a1,<0.7' nagents-channel-telegram-bot

This package requires the Channel API in Nagents 0.6, including its alpha releases: nagents>=0.6.0a1,<0.7. To test a connector alpha before either feature PR is merged, explicitly enable prereleases:

python -m pip install --pre --upgrade 'nagents>=0.6.0a1,<0.7' nagents-channel-telegram-bot
# Replace N with the published tag's alpha number or manual workflow run number:
python -m pip install --pre 'nagents-channel-telegram-bot==0.1.0aN'

The core alpha must be published before dependency-resolving CI or test installs can succeed. Web integration needs a Nagents build exposing ChannelPlugin, ChannelCommand, and ChannelActivity, as well as the web channel host.

Create a bot and start a standalone shared-session listener

1. In Telegram, create a bot using @BotFather and /newbot.
2. Set TELEGRAM_BOT_TOKEN in your application's environment. Keep it out of source files. Set your provider's key (the example uses OPENAI_API_KEY).
3. Start a private conversation with the bot, or add it to a group/channel with the permissions needed for your intended operations. Telegram's group privacy mode controls which group messages the bot receives; configure it in BotFather as needed. Bots cannot initiate arbitrary private conversations.
4. Run exactly one polling consumer per bot token. Polling cannot coexist with a webhook. If a previous application configured one, explicitly remove it as part of your own setup; this connector never calls deleteWebhook or drops the pending queue on startup. A Telegram 409 stops polling with a sanitized error.
5. Configure admission with allowed_user_ids and/or allowed_usernames, and use private_chats_only: true for individual private conversations. Optional allowed_chat_ids further restricts the destination chats. All lists default to empty and private mode defaults to false, preserving unconstrained ingress. See Sender and private-chat admission.

Use a stable session ID, channel name, bot identity, and persistent session database across restarts. Each connector attached to the Agent must have a unique name; give a second bot a different name. In this standalone example history is shared, so choose admitted chats with that shared identity in mind. The admission settings filter inbound events; the host owns outbound destination authorization.

The Agent runtime opens the channel, owns the polling task, and cancels/awaits it before closing resources. Ctrl+C cancels the example's listener. If using the Channel directly, follow the same order: open(), start listen(receive), cancel and await that task, then close() in finally. close() stops and joins owned typing keepalives and releases the HTTP session; the polling task belongs to its caller. Cleanup is shielded against cancellation and joined before cancellation propagates. Failed or cancelled open() also closes the HTTP session. Repeated open()/close() calls are supported. Lifecycle operations are serialized; opening during shutdown fails, and activity cannot start new workers while closing.

Explicit discovery and configuration

The distribution registers this entry point:

[project.entry-points."nagents.channels"]
telegram-bot = "nagents_channel_telegram_bot:plugin"

from nagents.channels import load_channel

channel = load_channel("telegram-bot", {
    "token_env": "TELEGRAM_BOT_TOKEN",
    "name": "telegram",
    "allowed_chat_ids": ["123456789", "-1001234567890"],
    "poll_timeout": 30,
})

nagents_channel_telegram_bot.plugin is a callable ChannelPlugin descriptor: its display name is Telegram Bot, its factory is TelegramBot.from_config, and its config_schema is a flat JSON object schema. Hosts can inspect this metadata without connecting to Telegram, then call the object with configuration:

from nagents_channel_telegram_bot import plugin

print(plugin.name)
print(plugin.config_schema)  # Static schema only; contains no saved credentials.
channel = plugin({"token_env": "TELEGRAM_BOT_TOKEN", "name": "telegram"})

from_config(dict[str, ChannelValue]) supports only these keys and rejects unknown keys and incorrect types:

Provide either token or token_env, never both. Ambiguity is rejected by key presence even when one value is empty. An explicitly empty/malformed token fails validation instead of falling back to the environment. Omit both keys to use the default environment variable. token_env deliberately has no schema default, so a generated form will not inject it alongside a private token. The optional schema name field is read-only for management clients: the web host injects its connection ID. Constructors/factories never retain the configuration dictionary or put credential values into errors or descriptor metadata.

Direct Python construction remains available: TelegramBot(token, *, name="telegram", allowed_chat_ids=(), allowed_user_ids=(), allowed_usernames=(), private_chats_only=False, poll_timeout=30, base_url="https://api.telegram.org"). For the constructor only, all three admission lists accept a list or tuple; factories require JSON lists. The optional base_url is a trusted operator-configured origin (no path, credentials, query, or fragment), never model input. HTTPS is required except for HTTP loopback/localhost test servers. It changes where the token is sent; use only dummy tokens in local tests. Imports and constructors make no network requests. open() authenticates with getMe.

Sender and private-chat admission

The connector validates admission before delivering any envelope to the host, so rejected input cannot reach host commands, session routing or model execution. Rejected callbacks also receive no answerCallbackQuery protocol acknowledgement. The polling offset still advances past discarded updates so they do not block the queue. Accepted callbacks retain their one-shot acknowledgement before host delivery.

The policy is:

(both user lists empty OR user ID matches OR username matches)
AND (chat list empty OR chat ID matches)
AND (private mode off OR valid private chat belonging to the acting user)

• Either nonempty user list enables strict human-sender validation. For new and edited messages the sole authority is Telegram's top-level message.from or edited_message.from. For buttons it is callback_query.from, never the original message author, which is commonly the bot itself.
• A sender must have a positive integer id (booleans and numeric strings are rejected) and an explicit boolean is_bot: false. An absent username is allowed for an ID match. A present username must be valid, even when the ID matches. Missing/malformed senders and all bots are discarded while user filtering is on.
• Incoming usernames have no @; configuration may have one leading @. Both use exactly 5–32 ASCII letters, digits or underscores, compared in lowercase. Whitespace, Unicode lookalikes, punctuation, wrong types and out-of-range lengths are rejected, rather than stripped or ignored. Configuration errors fail creation; invalid sender identities are discarded. Lists are copied, normalized and deduplicated.
• Text, captions, mentions (including text_mention users), display names, chat usernames, forward authors, reply authors and quotes never grant access. A trusted human may forward another person's content, but forwarded text remains ineligible for host-command parsing.
• Message/edit sender_chat presence, including anonymous group administrators, and channel-post updates are rejected while user filtering is on. Restricted events need a valid private/group/supergroup chat; channel/unknown chat types are rejected. For callbacks, the source message's author/sender_chat is only provenance, not the clicking user's identity.
• private_chats_only: true also requires a valid human sender when both user lists are empty. It requires chat.type == "private", a positive integer chat ID equal to the acting sender's ID, and no source sender_chat. Thus a trusted clicker cannot authorize a different private destination. Inaccessible callback source messages remain supported when they carry valid private chat and message IDs; the original message's from is not required.
• With both user lists empty and private mode false, legacy sender handling is retained, including other bots, anonymous senders and channel posts. The connector's own bot is always filtered when Telegram identifies it as sender.

Usernames are mutable and may be reassigned. Prefer allowed_user_ids for stable account identity; supplying a username as well deliberately grants access by either criterion, rather than pinning that username to an ID. ID configuration rejects whitespace, signs on positive user IDs, leading zeroes and non-string values.

For three separate private conversations, a generic host configuration is:

{
  "token_env": "TELEGRAM_BOT_TOKEN",
  "allowed_usernames": ["@example_user_one", "example_user_two", "example_user_three"],
  "private_chats_only": true,
  "poll_timeout": 30
}

Replace the example usernames with trusted accounts in the host configuration. If the host privately injects token, omit token_env. Each user must start their own private chat with the bot. An empty chat list allows those trusted accounts to use their own private chat IDs without pre-discovering them. The web host's default per-chat routing provides separate sessions; standalone Agent.listen(session_id=...) still shares one session. A user allowlist alone permits trusted users in groups, where replies are visible to unverified group members: enable private mode for private per-user conversations.

These settings are inbound admission controls. send, edit and delete still use the host-authorized destination; there is no inferred username-to-destination mapping or outbound user lookup. The host must enforce session-owner-to-destination authorization. Typing retains its existing chat-list filter.

Web-host installation and routing

This package implements the connector side of the web integration contract. The channel-management UI, credential storage and session routing are provided by the Nagents host; availability in a deployed application depends on that host's version. Installing this package alone does not deploy or enable a web UI.

For a host that implements channel management:

1. Install the connector through the application's existing approved shell, using the host-provided persistent plugin_path shown in its channel catalog. With compatible Nagents and aiohttp already installed in the host environment:

   python -m pip install --pre --no-deps --target "<plugin_path shown by the host>" nagents-channel-telegram-bot
   

   The destination is operator/host configuration, not an inbound Telegram value.

2. Use the management UI's Refresh action. The installed telegram-bot entry point supplies the descriptor and schema for the plugin picker/configuration form. When upgrading this connector in a running host, restart the host process to load the new code/schema; Refresh alone can retain already imported modules.

3. Configure a connection with either the private token secret field or a token_env reference. Omit the unused key. The host stores secrets separately from public config, outside the workspace, and does not return saved values in its management responses. The descriptor's writeOnly flag identifies token as a secret; no credential value is embedded in the schema.

4. Set the user admission lists and private mode, optional chat list, poll timeout, enabled state and host's main-session selection. The connection ID becomes the connector's stable name. Keep one polling consumer per bot token across all host instances.

Admission settings are captured when a connector is constructed. After changing configuration, the host must recreate/reopen that connection (or restart the host); closing/reopening the same Python object does not reread saved configuration.

The web host binds each (name, conversation_id) to a separate persisted session by default and serializes model execution against its shared Harness. Session ownership and command restrictions depend on the host version: older hosts allow cross-chat reattachment. For isolated conversations, use a host that permanently retains each session's chat owner and limits listing, selection, and outbound tools to that owner. Connector admission alone cannot enforce that storage policy. thread_id remains the Telegram topic target inside its chat. Agent.listen(session_id=...) remains available for applications that deliberately want the single shared identity shown above.

Host command parsing

channel.command(message) is synchronous and performs no I/O. It returns a ChannelCommand for the host to interpret, or None for ordinary model input:

The host owns listing, creating, validating and reattaching sessions, including the meaning of main, default, and new. The connector never queries storage, changes a binding, or sends a command response itself. A standalone application can use this hook explicitly; parsing alone does not change its Agent session.

Parsing is deliberately limited to new message updates with text at offset zero. Edits, channel posts, captions, callbacks and forwarded messages are not host commands. Recognized names are lowercase, followed by the end of the token or ASCII whitespace. /sessions takes no arguments; /session and /new preserve their argument text apart from surrounding whitespace. Unrecognized slash text returns None.

When entities is present, parsing requires one matching bot_command entity at UTF-16 offset zero, with the exact command-token length and valid entity ranges. Empty/malformed annotations or other formatting at the token's start prevent recognition. If entities are absent entirely, the same strict literal token parser is used as a fallback. /session@your_bot and the other @bot forms are accepted only when the suffix matches the username learned from getMe (case-insensitively). If that optional username was not returned, addressed commands stay ordinary input. Telegram entity metadata retains only type, offset, and length; arbitrary entity fields are not copied.

Host activity and typing

After opening the channel, the host can signal activity independently of text:

from nagents.channels import ChannelActivity

await channel.activity(ChannelActivity(
    conversation_id="-1001234567890", active=True,
    thread_id="42", session_id="root-session-a",
))
# When that session finishes or is cancelled:
await channel.activity(ChannelActivity(
    conversation_id="-1001234567890", active=False,
    thread_id="42", session_id="root-session-a",
))

• The first sendChatAction(action="typing") is attempted immediately, with a five-second HTTP timeout, then repeated after a four-second interval. No text reply or model tool call is generated. A known rate limit defers the first attempt as well; starting activity does not wait through that cooldown.
• One worker owns each (conversation_id, thread_id), with at most 64 workers per connector. Additional targets beyond that limit are ignored rather than queued. Repeated starts for the same key/session are idempotent.
• Starting the same target for a different session_id cancels/joins its previous worker. A late stop for the old session cannot stop the new owner's activity. Supply the same session ID on start/stop; empty IDs are their own distinct owner.
• Remote errors are best-effort and do not fail model execution or log exception bodies/URLs. Each period attempts the HTTP operation once. A Telegram retry_after delays subsequent indicators across this bot's active targets and survives ownership changes; the cancellable cooldown is not shortened to retry early. Other transient/uncertain failures wait for the next normal interval.
• Stops cancel/join local work. There is no fake cancel HTTP action: Telegram's existing icon expires within five seconds or disappears when a bot message arrives. Telegram does not support this method for channel chats or channel direct-message chats; those errors are handled as best-effort failures.
• Chat/thread IDs and activity field types are validated before HTTP. The chat admission list also filters indicators. Activity while closed/closing is a no-op. Cancelling a new start while its first request is in flight cleans up its worker; cancelling a duplicate start does not cancel the original owner.
• close() stops all workers and joins shielded cleanup before releasing HTTP resources. The caller still owns cancellation of its polling/listen task.

Incoming events and acknowledgement

Polling explicitly requests message, edited_message, channel_post, edited_channel_post, and callback_query, with at most 20 updates per batch.

Metadata preserves chat, sender, timestamps, thread, forwarding, external reply, quote, album, and compact same-chat reply provenance in reply_to_message when available. For example, update 100 carrying message 10 in reply to message 9 produces message_id="100", reply_to="10", and metadata["in_reply_to"]="9". The model can reuse conversation_id, thread_id, and reply_to directly with channel_send to reply to this event. in_reply_to preserves historical provenance rather than selecting that response target. Callback metadata includes its ID, sender and data; the top-level message provenance refers to the button's source message. Callback contents are external input, not commands to execute automatically.

Photos (largest area), documents, audio, voice, video, video notes, animations and stickers become ChannelAttachment references such as telegram:file:<file_id>. MIME type, filename, file size and available Telegram file/dimension/duration metadata are included. Animations are not duplicated as documents. References are bot-scoped; no getFile, download, transcription, execution, or credential-bearing file URL is produced. Albums arrive as individual updates sharing media_group_id.

The following are deliberately discarded and acknowledged by a subsequent poll:

• Events outside the configured user/chat/private admission policy; messages or callbacks whose acting from.id identifies this bot. Other bots and channel posts remain supported only with user/private filtering disabled. Channel posts may not identify the sending bot, so legacy own-message attribution is only possible when Telegram supplies it.
• Unsupported update types (including stale updates from earlier allowed-update settings), service/content types without supported text or files, and inline callbacks without an addressable chat.
• Business/guest contexts, channel direct-message topics and zero-ID ephemeral or scheduled messages, which require routing fields this connector does not expose.

Chat-backed callbacks, including inaccessible source messages with a usable chat and message ID, are admitted when they pass all filters. answerCallbackQuery is attempted once, after filtering/mapping and before durable host admission, with a five-second timeout and no text/alert/URL. This only clears the client's progress indicator; it is a protocol acknowledgement, not an Agent reply or a Telegram update acknowledgement. Filtered, unsupported and unapproved callbacks receive no such acknowledgement, including inline callbacks. Failure/expiry does not discard an accepted event; callback_acknowledged records whether Telegram confirmed it. There is no redundant callback-answer model action.

For admitted events, the offset advances only after await receive(event) returns, which the Nagents runtime defines as durable inbox admission. The next getUpdates call confirms that offset to Telegram. Receive failure or cancellation leaves the current update unacknowledged. Earlier admitted events in the batch may already be acknowledged; later ones are not. There is no detached intake queue.

Acceptance does not mean model execution or outbound delivery succeeded. Offsets are in memory; a restart can replay an admitted update before Telegram saw the new offset. Nagents' durable inbox deduplicates using the stable connector name and update identity. Within a running instance, older/duplicate update IDs are skipped. This is at-least-once transport admission, not exactly-once delivery. Telegram retains pending updates for at most 24 hours; keep the durable core inbox and its retention policy configured for your application.

Explicit outbound tools

Nagents exposes channel_send and channel_action to the model for attached channels. The local on_event observer and final assistant response do not send anything. The connector advertises receive, send_text, commands, and typing, plus the two action schemas below. An application can also call the Channel directly:

from nagents.channels import ChannelSend

# After channel.open(), or while the Agent runtime has it open:
delivery = await channel.send(ChannelSend(
    destination="-1001234567890",
    text="Plain text, including literal *asterisks*.",
    thread_id="42",
    reply_to="123",
))
telegram_id = delivery.message_ids[0]  # A tuple of confirmed Telegram ID strings.

await channel.action("edit_message", {
    "destination": "-1001234567890",
    "message_id": telegram_id,
    "text": "Updated plain text.",
})
await channel.action("delete_message", {
    "destination": "-1001234567890",
    "message_id": telegram_id,
})

• send calls sendMessage, with no parse mode or entities. Text must be nonempty valid Unicode and at most 4096 UTF-16 code units (an astral emoji counts as two). Overlength text is rejected before HTTP; there is no automatic chunking.
• Destinations must be nonzero canonical decimal chat ID strings, not usernames. Thread, reply, and action message IDs must be positive decimal strings. IDs are bounded by signed 64-bit range; whitespace, leading zeros, booleans, lists and numeric values in place of strings are rejected.
• thread_id becomes message_thread_id; reply_to uses reply_parameters with allow_sending_without_reply=False. Invalid or missing Telegram targets fail; the connector never falls back to another thread or sends without the reply.
• Outbound attachments and nonempty send metadata are explicitly unsupported. There are no implicit uploads, keyboards, formatting or arbitrary API options.
• edit_message: exactly destination, message_id, text; calls editMessageText. delete_message: exactly destination, message_id; calls deleteMessage. All fields are strings. Unknown/missing fields and actions are rejected. Actions address a chat-local message, so do not accept a thread override. Success returns {"ok": true, "destination": "...", "message_id": "..."}.
• Telegram's edit/delete permission and age restrictions still apply. Group migrations do not cause automatic retargeting.

Failures and retries

Only the read operations getMe and getUpdates retry transient transport, malformed-response, rate-limit or server failures: at most three retries per request, with 1/2/4-second exponential delays. A valid Telegram retry_after increases the delay. No sleep exceeds 60 seconds: a larger requested delay stops the operation and surfaces the delay rather than retrying earlier than requested. All waits are cancellable. HTTP/API 401, 403 and 409 fail immediately.

Sends, edits, deletes and callback acknowledgements are never automatically retried. Transport failures, server failures or malformed delivery confirmations raise ChannelError(outcome_unknown=True) for outbound operations because Telegram may already have acted. Do not blindly repeat such a tool call. Explicit API rejections expose retry_after where provided and have a known unsuccessful outcome. Cancellation during outbound HTTP propagates cancellation; its remote outcome must also be treated as unknown by the caller.

Errors use fixed, sanitized descriptions and status codes, not Telegram error bodies, tokens, request URLs or underlying HTTP exception text. The connector does not log requests; redirects, environment proxies and cookie persistence are disabled. Responses are limited to 8 MiB. If adding application-level HTTP tracing, remember that the Telegram API protocol includes the token in its request path.

Development and releases

Run all Python tooling in a virtual environment:

python -m pip install --pre -e '.[dev]'
python -m pytest
pre-commit run --all-files
python -m build
python -m twine check dist/*

Pre-commit uses Ruff and strict mypy from the active environment, so install the development extras first. The tests use a loopback aiohttp server and dummy tokens; they never call Telegram or an LLM provider. CI runs on Ubuntu with Python 3.11–3.14 and Windows with Python 3.13, and checks installation of the built wheel.

Before a Nagents 0.6 alpha is published, maintainers testing against a local checkout of the frozen Channel contracts can install that checkout and this package with python -m pip install --no-deps -e <path> for each, then install the development tools separately. This is a local verification override; released dependency metadata remains nagents>=0.6.0a1,<0.7.

Draft PR milestones and feature-branch alphas

Tested milestones are submitted as draft PRs in this repository. The parent/repository owner handles the initial main seed, feature branches, commits, draft PR creation, and publishing setup.

The initial main seed contains only LICENSE, .gitignore, and a short README. All package code, release tooling, and workflows belong to the feature branch's draft PR. The first alpha can be published from that feature commit before the workflow implementation is merged.

First alpha: explicit prerelease tag on the feature commit

After the feature commit's tests pass, the repository owner can push an unused alpha tag such as v0.1.0a1 pointing to that exact commit. The commit must contain publish.yml, reusable ci.yml, tools/release.py, and the package/tests. Unlike manual dispatch, a tag-push workflow can run from the tagged commit even when its definition is not yet on the default branch.

• The workflow pins the tagged commit's SHA and classifies canonical vX.Y.ZaN tags as alpha releases; N must be a positive integer.
• The tag's release base must match project.version. With the checked-in base 0.1.0, tag v0.1.0a1 stamps 0.1.0a1 into the test/build metadata. A tag for another base, beta/RC tag, or noncanonical version fails validation.
• Alpha tags may point directly to the feature branch, without main ancestry. Stable tags retain the main-history restriction described below.
• Pushing an ordinary feature-branch commit runs CI but does not publish. Publication requires this explicit release tag or a manual dispatch.

The owner creates/pushes the tag; no package version change needs to be committed. Use a fresh tag/alpha number for another tagged release. PyPI does not overwrite an already-published version.

Future option: manual feature-ref dispatch after workflow review/merge

GitHub exposes workflow_dispatch only after its definition is on the default branch. Once the workflow draft PR is reviewed and merged into main:

1. Open Actions → Publish → Run workflow and leave the workflow branch on main. Set feature-ref to the feature branch, full ref, or commit SHA.
2. The workflow resolves that ref once and records its full commit SHA. Every subsequent test/build checkout uses that SHA, even if the branch moves.
3. Manual dispatch is alpha-only. tools/release.py derives 0.1.0a<github.run_number> from the checked-out project.version = "0.1.0". The same deterministic metadata is stamped before CI tests and before the release build. No source version change is committed.

Use a new dispatch to publish another alpha: it gets a new run number. Rerunning an already-published workflow keeps the same version, which PyPI will not overwrite. Tagged and manually dispatched alphas share the same PyPI version namespace, so choose tag numbers that have not already been published by either path.

Shared test/build gates

Both alpha paths run the full CI matrix: lint, typing, tests, distribution checks, and installed-wheel tests. Each checkout verifies the pinned source SHA and stamps the same selected version before testing. The publishing build waits for those checks, builds that exact commit with identical metadata, and tests the actual wheel it uploads. It also verifies the installed version against the tag or manual run number. The publishing job downloads only that run's SHA-named artifact; it does not check out a fresh branch tip or rebuild the package.

The workflow summary records the source SHA for linking the alpha to its draft PR.

Stable releases and Trusted Publishing

Stable releases use canonical vX.Y.Z tags only. The tag must point to a commit already on the reviewed main history, and must exactly match the canonical stable project.version (for example, v0.1.0). Feature-only stable tags and version mismatches fail before publishing. Alpha tags always take the alpha path and cannot publish a stable version. Protect main with the repository's reviewed-PR merge policy; the workflow enforces main ancestry, while that policy enforces review. The stable path uses the same pinned-source test/build/artifact gates as alphas.

All release paths use publish.yml, the pypi environment, and id-token: write only in the publishing job. Configure the PyPI pending Trusted Publisher for owner abi-jey, repository nagents-channel-telegram-bot, workflow publish.yml, and environment pypi. No API key or .pypirc is needed.
