You can get up to 200 chat members at once.
|
|
A chat can be either a basic group, a supergroup or a channel.
|
|
You must be admin to retrieve the members list of a channel (also known as "subscribers").
|
|
For a more convenient way of getting chat members see :meth:`~Client.iter_chat_members`.
|
|
|
|

|
|
chat_id (``int`` | ``str``):
|
|
Unique identifier (int) or username (str) of the target chat.
|
|
|
|

|
|
Sequential number of the first member to be returned.
|
|
Only applicable to supergroups and channels. Defaults to 0 [1]_.
|
|
|
|
limit (``int``, *optional*):

|
Limits the number of members to be retrieved.

|
|
|
query (``str``, *optional*):
|
|
Query string to filter members based on their display names and usernames.
|
|
Only applicable to supergroups and channels. Defaults to "" (empty string) [2]_.
|
|
|
|
filter (``str``, *optional*):
|
|
Filter used to select the kind of members you want to retrieve. Only applicable for supergroups
|
|
and channels. It can be any of the followings:
|
|
*"all"* - all kind of members,
|
|
*"kicked"* - kicked (banned) members only,
|
|
*"restricted"* - restricted members only,
|
|
*"bots"* - bots only,
|
|
*"recent"* - recent members only,
|
|
*"administrators"* - chat administrators only.
|
|
Only applicable to supergroups and channels.
|
|
Defaults to *"all"*.
|
|
|
|
.. [1] Server limit: on supergroups, you can get up to 10,000 members for a single query and up to 200 members
|
|
on channels.
|
|
|
|
.. [2] A query string is applicable only for *"all"*, *"kicked"* and *"restricted"* filters only.
|
|
|
|
Returns:
|
|
List of :obj:`ChatMember`: On success, a list of chat members is returned.
|
|
|
|
Raises:
|
|
ValueError: In case you used an invalid filter or a chat id that belongs to a user.
|
|
|
|
Example:
|
|
.. code-block:: python
|
|
|
|
# Get first 200 recent members
|
|
app.get_chat_members("pyrogramchat")
|
|
|
|
# Get all administrators
|
|
app.get_chat_members("pyrogramchat", filter="administrators")
|
|
|
|
# Get all bots
|
|
app.get_chat_members("pyrogramchat", filter="bots")
