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).
|
|
|
|
from_chat_id (``int`` | ``str``):
|
|
Unique identifier (int) or username (str) of the source chat where the original message was sent.
|
|
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).
|
|
|
|
message_ids (``iterable``):
|
|
A list of Message identifiers in the chat specified in *from_chat_id* or a single message id.
|
|
Iterators and Generators are also accepted.
|
|
|
|
disable_notification (``bool``, *optional*):
|
|
Sends the message silently.
|
|
Users will receive a notification with no sound.
|
|
|
|
as_copy (``bool``, *optional*):
|
|
Pass True to forward messages without the forward header (i.e.: send a copy of the message content).
|
|
Defaults to False.
|
|
|
|
remove_caption (``bool``, *optional*):
|
|
If set to True and *as_copy* is enabled as well, media captions are not preserved when copying the
|
|
message. Has no effect if *as_copy* is not enabled.
|
|
Defaults to False.
|
|
|
|
Returns:
|
|
:obj:`Message` | :obj:`Messages`: In case *message_ids* was an integer, the single forwarded message is
|
|
returned, otherwise, in case *message_ids* was an iterable, the returned value will be an object containing
|
|
a list of messages, even if such iterable contained just a single element.
|
|
|
|
Raises:
|
|
RPCError: In case of a Telegram RPC error.
