"""Send any media stored on the Telegram servers using a file_id.
|
|
|
|
This convenience method works with any valid file_id only.
|
|
It does the same as calling the relevant method for sending media using a file_id, thus saving you from the
|
|
hassle of using the correct method for the media the file_id is pointing to.
|
|
|
|
Parameters:
|
|
chat_id (``int`` | ``str``):
|
|
Unique identifier (int) or username (str) of the target chat.
|
|
For your personal cloud (Saved Messages) you can simply use "me" or "self".
|
|
For a contact that exists in your Telegram address book you can use his phone number (str).
|
|
|
|
file_id (``str``):
|
|
Media to send.
|
|
Pass a file_id as string to send a media that exists on the Telegram servers.
|
|
|
|
caption (``bool``, *optional*):
|
|
Media caption, 0-1024 characters.
|
|
|
|
parse_mode (``str``, *optional*):
|
|
Pass "markdown" or "html" if you want Telegram apps to show bold, italic, fixed-width text or inline
|
|
URLs in your caption. Defaults to "markdown".
|
|
|
|
disable_notification (``bool``, *optional*):
|
|
Sends the message silently.
|
|
Users will receive a notification with no sound.
|
|
|
|
reply_to_message_id (``int``, *optional*):
|
|
If the message is a reply, ID of the original message.
|
|
|
|
reply_markup (:obj:`InlineKeyboardMarkup` | :obj:`ReplyKeyboardMarkup` | :obj:`ReplyKeyboardRemove` | :obj:`ForceReply`, *optional*):
|
|
Additional interface options. An object for an inline keyboard, custom reply keyboard,
|
|
instructions to remove reply keyboard or to force a reply from the user.
|
|
|
|
Returns:
|
|
:obj:`Message`: On success, the sent media message is returned.
|
|
|
|
Raises:
|
|
RPCError: In case of a Telegram RPC error.
