LiveBot permissions
Which Telegram administrator permissions Defendy needs and what features they cover. The principle of least privilege.
Updated Jul 18, 2026
Defendy works only with the Telegram administrator permissions you have granted it. Grant the minimum required for the enabled modules.
Which permission covers what
| Telegram permission | What it's for |
|---|---|
| Delete messages | Filters (anti-spam, links, forwards, profanity, stop-words), cleanup of service messages, the /del and /purge commands. |
| Ban members | The /ban commands, punishments from warnings, a ban on captcha failure. |
| Restrict members | The /mute commands, night mode, restriction and mute at the captcha. |
| Pin messages | The /pin, /unpin, /unpinall, /repin commands. |
| Manage invite links | The /revokelink command. |
| Manage topics | Directing the bot's messages to forum topics (if the group is a forum). |
The principle of least privilege
- Don't grant all permissions at once. If you don't use pinning or topics, you can leave the corresponding permission ungranted.
- After changing permissions or the set of administrators, run
/reloadso the bot updates its data. - Defendy cannot restrict Telegram administrators — this is a limitation of the platform itself.
Checking
If a setting is saved but doesn't trigger, the cause is most often a missing permission. Check the bot's permissions in the Telegram group settings and take a look at the action log.
