ChannelActionsBot

Can be found on telegram as @ChannelActionsBot!

Features

• Auto Approve new join requests.
• Auto Decline new join requests.
• Custom welcome messages.
• Web dashboard + Telegram Mini App to manage settings, with dark mode and owner stats (daily approve/decline counters, most active chats).

Web dashboard / Mini App

The bot serves a dashboard (static SPA + JSON API) on PORT (default 8000) in both webhook and polling modes.

• Auth: inside Telegram, the Mini App authenticates automatically via signed initData; in a browser, the official Telegram Login Widget is used. Every settings change is re-verified against getChatMember, so only chat admins can change a chat's settings.
• Mini App setup: set WEBAPP_URL to your public HTTPS URL — the bot installs it as its menu button on startup. Optionally also create a Mini App via @BotFather → /newapp to give it a t.me/<bot>/<app> link.
• Login widget setup: in BotFather, /setdomain → your dashboard domain (required for browser login; the Mini App works without it).
• Webhook note: include my_chat_member in allowed_updates when setting your webhook, so the dashboard learns about chats automatically: .../setWebhook?url=<url>/<token>&allowed_updates=["message","callback_query","chat_join_request","my_chat_member"]
• Stats counters start from the day this version is deployed; the chart fills in over its first 14 days.
