Telegram is a cloud-based messaging app with a focus on security and speed. Build bots to send messages, manage chats, and interact with users..
Open any action to see what it takes and what it gives back.
Use this method to send answers to callback queries sent from inline keyboards. The answer will be displayed to the user as a notification at the top of the chat screen or as an alert.
Delete a message, including service messages. Limitations: cannot delete messages older than 48 hours in groups, forwarded messages, or content in protected chats (returns 400 'message can’t be deleted'). Bot must have delete/manage rights in the target chat; works reliably only on bot-authored messages in groups. Verify permissions via TELEGRAM_GET_CHAT or TELEGRAM_GET_CHAT_ADMINISTRATORS before calling. On flood control, Telegram returns HTTP 429 with a retry_after field; honor that backoff value.
Edit text messages sent by the bot. Only bot-authored messages can be edited; editing messages from other users will fail. In groups, the bot must have edit permissions.
Generate a new primary invite link for a chat; any previously generated primary link is revoked. The bot must be an administrator in the chat for this to work and must have the appropriate administrator rights.
Forward messages of any kind. Service messages can't be forwarded.
Get basic information about the bot using the Bot API getMe method. Returns fields like id, username, first_name, and capabilities. If the response returns ok=false, the bot token is invalid or revoked and must be replaced before any other API calls. Bot name, bio, and profile description are read-only via the Bot API; modify them via BotFather.
Get a list of administrators in a chat. On success, returns an Array of ChatMember objects containing information about all chat administrators except other bots. Only meaningful for supergroups and channels; private chats yield no useful data. The bot must be a member of the chat; if the bot has admin rights, its own entry will appear in the result, useful for verifying its permissions before moderation actions.
Get chat history messages via the getUpdates polling method, filtered by chat_id. Returns only updates from the specified chat. Bot can only retrieve messages sent after it joined the chat; missing older messages is expected. Requires no active webhook — a webhook causes HTTP 409 conflict; delete it before using this tool. Empty result arrays (ok=true) indicate no accessible messages, not a failure. Returned message dates are Unix timestamps in UTC seconds.
Get up to date information about the chat (current name of the user for one-on-one conversations, current username of a user, group or channel, etc.). The bot must be a member of or have access to the target chat; calls fail if the bot was never added, was removed, or is blocked.
Get a chat member's status/role (including the bot itself) to preflight permissions and troubleshoot 403/empty-history issues. Use before sending messages to verify bot membership and permissions.
Get the number of members in a chat. The bot must be an administrator in the chat for this to work. Insufficient admin permissions surface as authorization errors, not as a zero or empty count.
Use this method to receive incoming updates using long polling. An Array of Update objects is returned. IMPORTANT: This method will not work if an outgoing webhook is set up. Webhooks and getUpdates are mutually exclusive — call deleteWebhook first to switch modes (409 Conflict otherwise). Notes: - Only one method (webhook or polling) can be active at a time - Updates available for up to 24 hours if unclaimed - Recalculate offset after each response to avoid duplicates - Empty result array (ok=true) is valid, meaning no new updates - On HTTP 429, honor the retry_after value; keep polling to ~1 request/second - Only chats with updates since the bot joined or last offset appear in results - Update objects vary by type; always check update.message and update.message.text exist before accessing.
Send general files (documents) to a Telegram chat using the Bot API. Prefer over TELEGRAM_SEND_PHOTO when original file format or image resolution must be preserved. Rapid sends trigger flood control (HTTP 429 with `retry_after` seconds); limit to ~1 message/second per chat and wait the specified `retry_after` duration before retrying.
Send point on the map location to a Telegram chat using the Bot API.
Send a text message to a Telegram chat using the Bot API. Bots must be members of target groups/channels with post rights. Rate limit: ~1 msg/sec per chat, ~30 msg/sec globally; exceeding returns 429 with retry_after seconds that must be honored.
Send photos to a Telegram chat using the Bot API. Telegram compresses and re-encodes images; use TELEGRAM_SEND_DOCUMENT to preserve original resolution/format. Each call produces a separate post; no media-group/album support. Returns HTTP 429 with `retry_after` seconds when sending too rapidly.
Send a native poll to a Telegram chat using the Bot API.
Use this method to change the list of the bot's commands. See https://core.telegram.org/bots#commands for more details about bot commands.
