Telegram Blocks

These blocks let your agent interact with Telegram through the Bot API. They cover sending text, photos, video, audio, voice messages, and documents, as well as replying to, editing, and deleting messages. Media blocks accept URLs (passed directly to Telegram for server-side fetch), data URIs, and workspace:// references (resolved locally and uploaded via multipart form-data). All blocks require a Telegram Bot API token obtained from @BotFather.

Delete Telegram Message

What it is

Delete a message from a Telegram chat. Bots can delete their own messages and incoming messages in private chats at any time.

How it works

Calls the Telegram Bot API deleteMessage method with the provided chat_id and message_id. On success, outputs a status confirmation. Note that bots can only delete their own messages in any chat, or incoming messages in private chats. In groups, deleting other users' messages requires admin privileges.

Inputs

Input	Description	Type	Required
chat_id	The chat ID containing the message	int	Yes
message_id	The ID of the message to delete	int	Yes

Outputs

Output	Description	Type
error	Error message if the operation failed	str
status	Status of the operation	str

Possible use case

Automatically clean up expired notifications or temporary status messages sent by your bot. For example, after a user confirms an action, delete the original prompt message to keep the chat tidy.

Edit Telegram Message

What it is

Edit the text of an existing message sent by the bot.

How it works

Calls the Telegram Bot API editMessageText method with the target chat_id, message_id, and the new text. An optional parse_mode can be set to format the replacement text as Markdown or HTML. Only messages sent by the bot itself can be edited.

Inputs

Input	Description	Type	Required
chat_id	The chat ID containing the message	int	Yes
message_id	The ID of the message to edit	int	Yes
text	New text for the message (max 4096 characters)	str	Yes
parse_mode	Message formatting mode	"none" \| "Markdown" \| "MarkdownV2" \| "HTML"	No

Outputs

Output	Description	Type
error	Error message if the operation failed	str
message_id	The ID of the edited message	int
status	Status of the operation	str

Possible use case

Update a "Processing..." status message with the final result once a long-running task completes, so the user sees progress in-place rather than receiving a separate follow-up message.

Get Telegram File

What it is

Download a file from Telegram using its file_id. Use this to process photos, voice messages, or documents received.

How it works

First calls the getFile API method to resolve the file_id into a server-side file path, then downloads the raw bytes from Telegram's file server. The downloaded content is converted to a data URI and stored via the workspace file system, outputting a workspace:// reference (or data URI) that other blocks can consume.

Inputs

Input	Description	Type	Required
file_id	The Telegram file_id to download. Get this from trigger outputs (photo_file_id, voice_file_id, etc.)	str	Yes

Outputs

Output	Description	Type
error	Error message if the operation failed	str
file	The downloaded file (workspace:// reference or data URI)	str (file)
status	Status of the operation	str

Possible use case

Download a photo sent by a user and pass it to an image recognition or OCR block for processing, then reply with the extracted information.

Reply To Telegram Message

What it is

Reply to a specific message in a Telegram chat.

How it works

Calls the Telegram Bot API sendMessage method with a reply_to_message_id parameter, which creates a new message visually linked to the original. The reply appears with a quoted preview of the original message in the chat. An optional parse_mode enables Markdown or HTML formatting.

Inputs

Input	Description	Type	Required
chat_id	The chat ID where the message is	int	Yes
reply_to_message_id	The message ID to reply to	int	Yes
text	The reply text	str	Yes
parse_mode	Message formatting mode	"none" \| "Markdown" \| "MarkdownV2" \| "HTML"	No

Outputs

Output	Description	Type
error	Error message if the operation failed	str
message_id	The ID of the reply message	int
status	Status of the operation	str

Possible use case

In a group chat, reply directly to a user's question with an AI-generated answer so that the response is clearly threaded to the original question, keeping the conversation organized.

Send Telegram Audio

What it is

Send an audio file to a Telegram chat. The file is displayed in the music player. For voice messages, use the Send Voice block instead.

How it works

Calls the Telegram Bot API sendAudio method. If the input is an HTTP(S) URL, it is passed directly to Telegram which fetches the file server-side. For data URIs or workspace:// references, the file is resolved locally and uploaded via multipart form-data. Optional metadata like title, performer, and duration is included when provided.

Inputs

Input	Description	Type	Required
chat_id	The chat ID to send the audio to	int	Yes
audio	Audio file to send (MP3 or M4A format). Can be URL, data URI, or workspace:// reference.	str (file)	Yes

Send Telegram Document

What it is

Send a document (any file type) to a Telegram chat.

How it works

Calls the Telegram Bot API sendDocument method. URLs are passed directly for server-side fetch; data URIs and workspace:// references are resolved locally and uploaded via multipart form-data. A custom filename can be specified to control the display name shown to the recipient. The caption supports optional Markdown or HTML formatting via parse_mode.

Inputs

Input	Description	Type	Required
chat_id	The chat ID to send the document to	int	Yes
document	Document to send (any file type). Can be URL, data URI, or workspace:// reference.	str (file)	Yes

Send Telegram Message

What it is

Send a text message to a Telegram chat.

How it works

Calls the Telegram Bot API sendMessage method with the provided chat_id and text. Optional parameters include parse_mode (to render Markdown or HTML formatting), reply_to_message_id (to thread the message as a reply), and disable_notification (to send silently without triggering a sound on the recipient's device).

Inputs

Send Telegram Photo

What it is

Send a photo to a Telegram chat.

How it works

Calls the Telegram Bot API sendPhoto method. If the input is an HTTP(S) URL, it is passed directly to Telegram which fetches the image server-side (preferred for speed and efficiency). For data URIs or workspace:// references, the file is resolved to a local path, read as bytes, and uploaded via multipart form-data with the appropriate MIME type.

Inputs

Input	Description	Type	Required

Send Telegram Video

What it is

Send a video to a Telegram chat.

How it works

Calls the Telegram Bot API sendVideo method. URLs are passed directly for server-side fetch; data URIs and workspace:// references are resolved locally and uploaded via multipart form-data with MIME type detection. Optional duration metadata and parse_mode for the caption can be provided.

Send Telegram Voice

What it is

Send a voice message to a Telegram chat. Voice must be OGG format with OPUS codec.

How it works

Calls the Telegram Bot API sendVoice method. URLs are passed directly for server-side fetch; data URIs and workspace:// references are resolved locally and uploaded via multipart form-data. The file must be in OGG format encoded with the OPUS codec for Telegram to display it as a voice message (with a waveform). Other formats will not render correctly as voice messages.
