"""Get one or more messages from a chat by using message identifiers.
You can retrieve up to 200 messages at once.
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 (``iterable``, *optional*):
Pass a single message identifier or a list of message ids (as integers) to get the content of the
message themselves. Iterators and Generators are also accepted.
reply_to_message_ids (``iterable``, *optional*):
Pass a single message identifier or a list of message ids (as integers) to get the content of
the previous message you replied to using this message. Iterators and Generators are also accepted.
If *message_ids* is set, this argument will be ignored.
replies (``int``, *optional*):
The number of subsequent replies to get for each message.
Pass 0 for no reply at all or -1 for unlimited replies.
Defaults to 1.
Returns:
:obj:`~pyrogram.types.Message` | List of :obj:`~pyrogram.types.Message`: In case *message_ids* was an
integer, the single requested message is returned, otherwise, in case *message_ids* was an iterable, the
returned value will be a list of messages, even if such iterable contained just a single element.
Example:
.. code-block:: python
# Get one message
app.get_messages(chat_id, 12345)
# Get more than one message (list of messages)
app.get_messages(chat_id, [12345, 12346])
# Get message by ignoring any replied-to message
app.get_messages(chat_id, message_id, replies=0)
# Get message with all chained replied-to messages
app.get_messages(chat_id, message_id, replies=-1)
# Get the replied-to message of a message
app.get_messages(chat_id, reply_to_message_ids=message_id)
Raises:
ValueError: In case of invalid arguments.
