  title: BotMux API
  description: >
    REST API for BotMux — a multi-bot Telegram management and proxy platform.


    All endpoints return JSON. Errors return `{"error": "message"}` with HTTP
    500 (or 400/401/403/404 where applicable).


    **Authentication**: Use a Bearer API key (`Authorization: Bearer bmx_...`)
    or a session cookie obtained via `/api/auth/login`.

      Transparent proxy to api.telegram.org with message capture and method
      interception.


      Several Telegram Bot API methods are intercepted by BotMux instead of
      being forwarded:

      - `setWebhook` — configures the bot's backend URL in BotMux and enables
      proxy mode (auto-registration of unknown tokens requires
      `BOTMUX_ALLOW_AUTO_REGISTER=1`)

      - `deleteWebhook` — clears the backend URL and disables proxy mode

      - `getWebhookInfo` — returns BotMux's internal webhook state

      - `getUpdates` — served from BotMux's internal queue when long polling is
      enabled; returns empty for any other known bot to prevent conflict errors

      - `logOut` — returns success without forwarding (prevents token being
      disabled for 10 minutes)

      - `close` — returns success without forwarding (prevents bot instance
      shutdown on Telegram's side)


      A file download endpoint at `/tgapi/file/bot{TOKEN}/{file_path}` is also
      available as a drop-in replacement for Telegram's file download URL.
