# Telegram Bot API
Send messages to Telegram using a bot token.
## Setup
1. Create bot via @BotFather on Telegram
2. Copy the bot token
3. Store token:
```bash
mkdir -p ~/.config/telegram
echo "YOUR_BOT_TOKEN" > ~/.config/telegram/bot_token
```
4. Get chat ID: Send `/start` to your bot, then visit:
`https://api.telegram.org/bot<TOKEN>/getUpdates`
## Send Text Message
```bash
TOKEN=$(cat ~/.config/telegram/bot_token)
CHAT_ID="123456789"
curl -s -X POST "https://api.telegram.org/bot${TOKEN}/sendMessage" \
-H "Content-Type: application/json" \
-d "{\"chat_id\": \"${CHAT_ID}\", \"text\": \"Hello from Clawdbot!\"}"
```
## Formatting (MarkdownV2)
```bash
curl -s -X POST "https://api.telegram.org/bot${TOKEN}/sendMessage" \
-H "Content-Type: application/json" \
-d '{
"chat_id": "'$CHAT_ID'",
"text": "*Bold* _italic_ `code` [link](https://example.com)",
"parse_mode": "MarkdownV2"
}'
```
Escape these chars in MarkdownV2: `_*[]()~>#+-=|{}.!`
