-      * `caption`: caption for a media content (0-200 characters)
+      * `caption`: caption for a media content (0-1024 characters)
       * `disable_notification`: send a message silently in a channel
       * `disable_web_page_preview`: disable link previews for links in a text message
       * `long_message`: truncate (default) or split text messages and captions that exceed Telegram API limits. Markdown and HTML tags can't span across messages and, if not opened or closed properly, will render as plain text.
