|
|
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).
|
|
|
|
message_ids (``int`` | ``Iterable[int]``):
|
|
A list of Message identifiers to delete (integers) or a single message id.
|
|
Iterators and Generators are also accepted.
|
|
|
|
revoke (``bool``, *optional*):
|
|
Deletes messages on both parts.
|
|
This is only for private cloud chats and normal groups, messages on
|
|
channels and supergroups are always revoked (i.e.: deleted for everyone).
|
|
Defaults to True.
|
|
|
|
Returns:
|
|
``bool``: True on success, False otherwise.
