Bot owners only, fetch main mini app preview information, see here » for more info.Note: technically non-owners may also invoke this method, but it will always behave exactly as bots.getPreviewMedias, returning only previews for the current language and an empty lang_codes array, regardless of the passed lang_code, so please only use bots.getPreviewMedias if you're not the owner of the bot.

The server does not know this session: the key was revoked, expired, or the call was made before authorisation. |
