-- | Request parameters for 'sendVideoNote'.
data SendVideoNoteRequest = SendVideoNoteRequest
  { sendVideoNoteChatId :: SomeChatId -- ^ Unique identifier for the target chat or username of the target channel (in the format @channelusername).
  , sendVideoNoteMessageThreadId :: Maybe MessageThreadId -- ^ Unique identifier for the target message thread (topic) of the forum; for forum supergroups only.
  , sendVideoNoteVideoNote :: InputFile -- ^ Video note to send. Pass a file_id as String to send a video note that exists on the Telegram servers (recommended) or upload a new video using multipart/form-data. More info on Sending Files ». Sending video notes by a URL is currently unsupported
  , sendVideoNoteDuration :: Maybe Int -- ^ Duration of sent video in seconds
  , sendVideoNoteLength :: Maybe Int -- ^ Video width and height, i.e. diameter of the video message
  , sendVideoNoteThumbnail :: Maybe InputFile -- ^ Thumbnail of the file sent; can be ignored if thumbnail generation for the file is supported server-side. The thumbnail should be in JPEG format and less than 200 kB in size. A thumbnail's width and height should not exceed 320. Ignored if the file is not uploaded using multipart/form-data. Thumbnails can't be reused and can be only uploaded as a new file, so you can pass “attach://<file_attach_name>” if the thumbnail was uploaded using multipart/form-data under <file_attach_name>. More info on Sending Files »
  , sendVideoNoteDisableNotification :: Maybe Bool -- ^ Sends the message silently. Users will receive a notification with no sound.
  , sendVideoNoteProtectContent :: Maybe Bool -- ^ Protects the contents of the sent message from forwarding and saving
  , sendVideoNoteReplyToMessageId :: Maybe MessageId -- ^ If the message is a reply, ID of the original message
  , sendVideoNoteAllowSendingWithoutReply :: Maybe Bool -- ^ Pass True, if the message should be sent even if the specified replied-to message is not found
  , sendVideoNoteReplyMarkup :: Maybe InlineKeyboardMarkup -- ^ Additional interface options. A JSON-serialized object for an inline keyboard, custom reply keyboard, instructions to remove reply keyboard or to force a reply from the user.
