.. include:: /_includes/usable-by/users.rst

Parameters:

chat_id (``int`` | ``str``):

The group, supergroup or channel id

user_ids (``int`` | ``str`` | List of ``int`` or ``str``):

Users to add in the chat

You can pass an ID (int), username (str) or phone number (str).

Multiple users can be added by passing a list of IDs, usernames or phone numbers.

forward_limit (``int``, *optional*):

How many of the latest messages you want to forward to the new members. Pass 0 to forward none of them.

Defaults to 100 (max amount).

Returns:

``bool``: On success, True is returned.

Example:

.. code-block:: python

# Add one member to a group or channel

await app.add_chat_members(chat_id, user_id)

# Add multiple members to a group or channel

await app.add_chat_members(chat_id, [user_id1, user_id2, user_id3])

# Change forward_limit (for basic groups only)

await app.add_chat_members(chat_id, user_id, forward_limit=25)
