Telegram uses a model called Updates to notify bots about any interaction: received messages, edits, inline button clicks, group joins, and more. When you connect a Telegram bot in Timely.ai, the platform automatically configures a webhook in the Telegram Bot API to receive those updates and transform them into workspace events. This page documents the raw update format — useful for debugging or direct integrations with the Telegram API.

​
How the webhook is registered

Timely.ai calls the setWebhook method of the Bot API pointing to its servers: 
POST https://api.telegram.org/bot{TOKEN}/setWebhook
{
  "url": "https://webhooks.timelyai.com.br/telegram/{CHANNEL_ID}",
  "allowed_updates": ["message", "edited_message", "callback_query", "my_chat_member"]
}
To check the current webhook configuration of your bot, use: 
curl https://api.telegram.org/bot{YOUR_TOKEN}/getWebhookInfo
If you manage the bot directly (without Timely as an intermediary), never configure two webhooks on the same token — Telegram delivers each update to only one endpoint.

​
Base structure of an Update

Every Telegram update has a unique and incrementing update_id, plus exactly one field with the event type: 
{
  "update_id": 123456789,
  "message": { ... }
}
Possible fields at the root level are: message, edited_message, channel_post, edited_channel_post, inline_query, callback_query, my_chat_member, chat_member, among others.

​
Payload: message

The most common type — a new message sent to the bot. 
{
  "update_id": 123456789,
  "message": {
    "message_id": 42,
    "from": {
      "id": 987654321,
      "is_bot": false,
      "first_name": "Ana",
      "last_name": "Souza",
      "username": "anasouza",
      "language_code": "pt-br"
    },
    "chat": {
      "id": 987654321,
      "first_name": "Ana",
      "last_name": "Souza",
      "username": "anasouza",
      "type": "private"
    },
    "date": 1713456789,
    "text": "Quero cancelar minha assinatura",
    "entities": [
      {
        "offset": 0,
        "length": 6,
        "type": "bold"
      }
    ]
  }
}

​
Message with media

{
  "update_id": 123456790,
  "message": {
    "message_id": 43,
    "from": { "id": 987654321, "first_name": "Ana", "is_bot": false },
    "chat": { "id": 987654321, "type": "private" },
    "date": 1713456850,
    "photo": [
      {
        "file_id": "AgACAgIAAxkBAAIBK2...",
        "file_unique_id": "AQADrN8xG...",
        "width": 320,
        "height": 240,
        "file_size": 12345
      },
      {
        "file_id": "AgACAgIAAxkBAAIBLG...",
        "file_unique_id": "AQADrN8xH...",
        "width": 1280,
        "height": 960,
        "file_size": 89012
      }
    ],
    "caption": "Segue a nota fiscal"
  }
}
Telegram sends multiple image sizes in the photo array. Always use the last element (highest resolution). To download: GET https://api.telegram.org/bot{TOKEN}/getFile?file_id={FILE_ID} then https://api.telegram.org/file/bot{TOKEN}/{file_path}.

​
Payload: edited_message

Sent when the user edits an already-sent message. Contains the same fields as message plus the edit_date field. 
{
  "update_id": 123456791,
  "edited_message": {
    "message_id": 42,
    "from": { "id": 987654321, "first_name": "Ana", "is_bot": false },
    "chat": { "id": 987654321, "type": "private" },
    "date": 1713456789,
    "edit_date": 1713456900,
    "text": "Quero pausar minha assinatura (editado)"
  }
}
Timely.ai treats edited_message as an update to the original message. Edit history is not stored — only the most recent content is displayed in the conversation.

​
Payload: callback_query

Triggered when the user clicks an inline keyboard button. Commonly used for interactive menu flows. 
{
  "update_id": 123456792,
  "callback_query": {
    "id": "4382bfdwdsb323b2d9",
    "from": {
      "id": 987654321,
      "is_bot": false,
      "first_name": "Ana",
      "username": "anasouza"
    },
    "message": {
      "message_id": 45,
      "from": { "id": 111111111, "is_bot": true, "first_name": "Timely Bot" },
      "chat": { "id": 987654321, "type": "private" },
      "date": 1713456950,
      "text": "Como posso te ajudar?",
      "reply_markup": {
        "inline_keyboard": [
          [
            { "text": "Suporte", "callback_data": "menu_suporte" },
            { "text": "Financeiro", "callback_data": "menu_financeiro" }
          ]
        ]
      }
    },
    "chat_instance": "-1234567890",
    "data": "menu_suporte"
  }
}
After receiving a callback_query, you must reply with answerCallbackQuery to dismiss the loading indicator in the client: 
POST https://api.telegram.org/bot{TOKEN}/answerCallbackQuery
{
  "callback_query_id": "4382bfdwdsb323b2d9",
  "text": "Abrindo menu de suporte..."
}

​
Idempotency via update_id

Telegram guarantees at-least-once delivery. In case of a network failure, the same update may be resent. Use update_id for deduplication: 
const processed = new Set<number>();

function handleUpdate(update: TelegramUpdate) {
  if (processed.has(update.update_id)) return; // duplicate
  processed.add(update.update_id);
  // process...
}
In production, persist the processed IDs in Redis or a database — not in memory.
