telegram

## Environment Setup **IMPORTANT**: Before using any Telegram commands, source the local `.env` file: ```bash source .skill.config ``` Credentials are stored in `.skill.config` (gitignored): ``` TELEGRAM_BOT_TOKEN=... TELEGRAM_CHAT_ID=... # Default chat (legacy, still works) ``` --- ## Multi-Chat Configuration Chat aliases are stored in `telegram-chats.json` (gitignored): ```json { "chats": { "default": { "id": "123456789", "name": "Personal", "description": "Default notifications" }, "alerts": { "id": "-100987654321", "name": "Alerts", "description": "Critical alerts" }, "house": { "id": "-4972420459", "name": "House Common", "description": "House group" } } } ``` ### Get chat ID by alias ```bash jq -r '.chats.house.id' .opencode/skill/telegram/telegram-chats.json ``` ### List all configured chats ```bash jq -r '.chats | to_entries[] | "\(.key): \(.value.name) (\(.value.id))"' .opencode/skill/telegram/telegram-chats.json ``` --- ## Quick Usage ### Send to default chat ```bash source .skill.config && curl -s -X POST "https://api.telegram.org/bot$TELEGRAM_BOT_TOKEN/sendMessage" \ -d "chat_id=$TELEGRAM_CHAT_ID" \ -d "text=Hello from OpenCode!" ``` ### Send to named chat (using jq) ```bash source .skill.config && CHAT_ID=$(jq -r '.chats.house.id' .opencode/skill/telegram/telegram-chats.json) && \ curl -s -X POST "https://api.telegram.org/bot$TELEGRAM_BOT_TOKEN/sendMessage" \ -d "chat_id=$CHAT_ID" \ -d "text=Hello House!" ``` ### Send to multiple chats ```bash source .skill.config && for chat in default house; do CHAT_ID=$(jq -r ".chats.$chat.id" .opencode/skill/telegram/telegram-chats.json) curl -s -X POST "https://api.telegram.org/bot$TELEGRAM_BOT_TOKEN/sendMessage" \ -d "chat_id=$CHAT_ID" \ -d "text=Broadcast message!" & done wait ``` ### Send with Markdown formatting ```bash source .skill.config && curl -s -X POST "https://api.telegram.org/bot$TELEGRAM_BOT_TOKEN/sendMessage" \ -d "chat_id=$TELEGRAM_CHAT_ID" \ -d "parse_mode=Markdown" \ -d "text=*Bold* and _italic_ and \`code\`" ``` ### Send with HTML formatting ```bash source .skill.config && curl -s -X POST "https://api.telegram.org/bot$TELEGRAM_BOT_TOKEN/sendMessage" \ -d "chat_id=$TELEGRAM_CHAT_ID" \ -d "parse_mode=HTML" \ -d "text=<b>Bold</b> and <i>italic</i> and <code>code</code>" ``` ### Send with links ```bash source .skill.config && curl -s -X POST "https://api.telegram.org/bot$TELEGRAM_BOT_TOKEN/sendMessage" \ -d "chat_id=$TELEGRAM_CHAT_ID" \ -d "parse_mode=Markdown" \ -d "text=Check out [this deal](https://facebook.com/marketplace/item/123)" ``` ### Send multi-line message ```bash source .skill.config && curl -s -X POST "https://api.telegram.org/bot$TELEGRAM_BOT_TOKEN/sendMessage" \ -d "chat_id=$TELEGRAM_CHAT_ID" \ -d "parse_mode=Markdown" \ --data-urlencode "text=*New Deals Found* 1. \$50 - Vintage Poster [View](link1) 2. \$30 - Movie Poster [View](link2)" ``` --- ## Verify Setup ### Check bot is working ```bash source .skill.config && curl -s "https://api.telegram.org/bot$TELEGRAM_BOT_TOKEN/getMe" | jq ``` ### Check credentials are set ```bash source .skill.config && echo "Token: ${TELEGRAM_BOT_TOKEN:0:10}... Chat: $TELEGRAM_CHAT_ID" ``` ### List all chats from config ```bash jq '.chats' .opencode/skill/telegram/telegram-chats.json ``` --- ## Common Gotchas - **Markdown escaping**: Use `\` before `_`, `*`, `` ` ``, `[` if they're literal - **URL encoding**: Use `--data-urlencode` for messages with special chars - **Chat ID**: Must be a number (personal) or starts with `-` (group/channel) - **Bot must be added to group**: For group chats, add bot as member first - **Group chat IDs are negative**: They typically start with `-100` for supergroups --- ## First-Time Setup (If Not Configured) ### 1. Create a bot 1. Open Telegram and message @BotFather 2. Send `/newbot` 3. Choose a name (e.g., "My OpenCode Bot") 4. Choose a username (must end in `bot`, e.g., "myopencode_bot") 5. Copy the token BotFather gives you ### 2. Get your chat ID 1. Message your new bot (just say "hi") 2. Run: ```bash curl -s "https://api.telegram.org/bot<YOUR_TOKEN>/getUpdates" | jq '.result[0].message.chat.id' ``` ### 3. Get group chat IDs 1. Add the bot to each group 2. Send a message in the group 3. Run: ```bash curl -s "https://api.telegram.org/bot<YOUR_TOKEN>/getUpdates" | jq '.result[] | select(.message.chat.type != "private") | {title: .message.chat.title, id: .message.chat.id}' ``` ### 4. Store bot token in .skill.config Add to `.skill.config`: ```bash TELEGRAM_BOT_TOKEN=your_token_here TELEGRAM_CHAT_ID=your_default_chat_id_here ``` ### 5. Initialize multi-chat config ```bash cp .opencode/skill/telegram/telegram-chats.example.json .opencode/skill/telegram/telegram-chats.json ``` Then edit `telegram-chats.json` to add your chats: ```json { "chats": { "default": { "id": "YOUR_PERSONAL_CHAT_ID", "name": "Personal", "description": "My personal notifications" }, "alerts": { "id": "GROUP_CHAT_ID", "name": "Alerts Group", "description": "System alerts" } } } ``` ### 6. Test it ```bash # Test default source .skill.config && curl -s -X POST "https://api.telegram.org/bot$TELEGRAM_BOT_TOKEN/sendMessage" \ -d "chat_id=$TELEGRAM_CHAT_ID" \ -d "text=OpenCode connected!" # Test named chat source .skill.config && CHAT_ID=$(jq -r '.chats.house.id' .opencode/skill/telegram/telegram-chats.json) && \ curl -s -X POST "https://api.telegram.org/bot$TELEGRAM_BOT_TOKEN/sendMessage" \ -d "chat_id=$CHAT_ID" \ -d "text=House chat connected!" ``` --- ## Adding New Chats ### Via getUpdates (recommended) 1. Add bot to the new group or message it privately 2. Send a message in that chat 3. Run: ```bash source .skill.config && curl -s "https://api.telegram.org/bot$TELEGRAM_BOT_TOKEN/getUpdates" | jq '.result[-1].message.chat' ``` 4. Add the chat to `telegram-chats.json` ### Discover all recent chats ```bash source .skill.config && curl -s "https://api.telegram.org/bot$TELEGRAM_BOT_TOKEN/getUpdates" | \ jq '[.result[].message.chat] | unique_by(.id) | .[] | {id, title: (.title // .first_name), type}' ``` --- ## Helper: Send Function For complex scripts, define a helper: ```bash telegram_send() { local chat_alias="${1:-default}" local message="$2" local parse_mode="${3:-Markdown}" source .skill.config local chat_id=$(jq -r ".chats.$chat_alias.id" .opencode/skill/telegram/telegram-chats.json) curl -s -X POST "https://api.telegram.org/bot$TELEGRAM_BOT_TOKEN/sendMessage" \ -d "chat_id=$chat_id" \ -d "parse_mode=$parse_mode" \ --data-urlencode "text=$message" } # Usage: telegram_send "house" "Hello from the house chat!" telegram_send "bargains" "*New deal found!*" "Markdown" ```
