Source & Trust

1. Repository: https://github.com/baontq23/node-telegram-cli

JSON Output Schemas

Inbox (conversation list)

1. name — contact/chat display name
2. peer — identifier to use as <peer> argument
3. peerType — "username" | "phone" | "id"
4. type — "user" | "group" | "channel"
5. unreadCount — number of unread messages
6. lastMessage — text/caption (empty string if media-only)
7. lastMessageId — use with ntg download <id> for media
8. mediaType — "photo" | "video" | "document" | "audio" | "voice" | "sticker" | "location" | "contact" | "poll" | null
9. date — ISO 8601 timestamp

Chat messages (inbox --chat)

1. id — message ID
2. date — ISO 8601 timestamp
3. sender — sender display name
4. text — message text/caption
5. mediaType — same values as above
6. isOutgoing — true if sent by you

Error Handling

1. Exit code 0 = success
2. Exit code 1 = error (not logged in, peer not found, etc.)
3. If not logged in, commands fail with: "Not logged in. Run ntg login first."

Important Notes

1. Do NOT use ntg chat <peer> — it is interactive, blocks stdin, not suitable for automation
2. Session persists until ntg logout is called — no re-login needed between commands
3. Downloaded files are saved to ~/.telegram-cli/downloads/
4. Always specify --chat <peer> when downloading media to identify the source chat
