Bots
====
Talking to Inline Bots
**********************
You can query an inline bot, such as `@VoteBot`__ (note, *query*,
not *interact* with a voting message), by making use of the
`GetInlineBotResultsRequest`__ request:
.. code-block:: python
from telethon.tl.functions.messages import GetInlineBotResultsRequest
bot_results = client(GetInlineBotResultsRequest(
bot, user_or_chat, 'query', ''
))
And you can select any of their results by using
`SendInlineBotResultRequest`__:
.. code-block:: python
from telethon.tl.functions.messages import SendInlineBotResultRequest
client(SendInlineBotResultRequest(
get_input_peer(user_or_chat),
obtained_query_id,
obtained_str_id
))
Talking to Bots with special reply markup
*****************************************
To interact with a message that has a special reply markup, such as
`@VoteBot`__ polls, you would use `GetBotCallbackAnswerRequest`__:
.. code-block:: python
from telethon.tl.functions.messages import GetBotCallbackAnswerRequest
client(GetBotCallbackAnswerRequest(
user_or_chat,
msg.id,
data=msg.reply_markup.rows[wanted_row].buttons[wanted_button].data
))
It's a bit verbose, but it has all the information you would need to
show it visually (button rows, and buttons within each row, each with
its own data).

===============================
Working with Chats and Channels
===============================
Joining a chat or channel
*************************
Note that `Chat`__\ s are normal groups, and `Channel`__\ s are a
special form of `Chat`__\ s,
which can also be super-groups if their ``megagroup`` member is
``True``.
Joining a public channel
************************
Once you have the :ref:`entity <entities>` of the channel you want to join
to, you can make use of the `JoinChannelRequest`__ to join such channel:
.. code-block:: python
from telethon.tl.functions.channels import JoinChannelRequest
client(JoinChannelRequest(channel))
# In the same way, you can also leave such channel
from telethon.tl.functions.channels import LeaveChannelRequest
client(LeaveChannelRequest(input_channel))
For more on channels, check the `channels namespace`__.
Joining a private chat or channel
*********************************
If all you have is a link like this one:
``https://t.me/joinchat/AAAAAFFszQPyPEZ7wgxLtd``, you already have
enough information to join! The part after the
``https://t.me/joinchat/``, this is, ``AAAAAFFszQPyPEZ7wgxLtd`` on this
example, is the ``hash`` of the chat or channel. Now you can use
`ImportChatInviteRequest`__ as follows:
.. -block:: python
from telethon.tl.functions.messages import ImportChatInviteRequest
updates = client(ImportChatInviteRequest('AAAAAEHbEkejzxUjAUCfYg'))
Adding someone else to such chat or channel
*******************************************
If you don't want to add yourself, maybe because you're already in,
you can always add someone else with the `AddChatUserRequest`__,
which use is very straightforward:
.. code-block:: python
from telethon.tl.functions.messages import AddChatUserRequest
client(AddChatUserRequest(
chat_id,
user_to_add,
fwd_limit=10 # allow the user to see the 10 last messages
))
Checking a link without joining
*******************************
If you don't need to join but rather check whether it's a group or a
channel, you can use the `CheckChatInviteRequest`__, which takes in
the `hash`__ of said channel or group.

Retrieving all chat members (channels too)
******************************************
In order to get all the members from a mega-group or channel, you need
to use `GetParticipantsRequest`__. As we can see it needs an
`InputChannel`__, (passing the mega-group or channel you're going to
use will work), and a mandatory `ChannelParticipantsFilter`__. The
closest thing to "no filter" is to simply use
`ChannelParticipantsSearch`__ with an empty ``'q'`` string.
If we want to get *all* the members, we need to use a moving offset and
a fixed limit:
.. code-block:: python
from telethon.tl.functions.channels import GetParticipantsRequest
from telethon.tl.types import ChannelParticipantsSearch
from time import sleep
offset = 0
limit = 100
all_participants = []
while True:
participants = client.invoke(GetParticipantsRequest(
channel, ChannelParticipantsSearch(''), offset, limit
))
if not participants.users:
break
all_participants.extend(participants.users)
offset += len(participants.users)
Note that ``GetParticipantsRequest`` returns `ChannelParticipants`__,
which may have more information you need (like the role of the
participants, total count of members, etc.)

Recent Actions
**************
"Recent actions" is simply the name official applications have given to
the "admin log". Simply use `GetAdminLogRequest`__ for that, and
you'll get AdminLogResults.events in return which in turn has the final
`.action`__.

__ https://lonamiwebs.github.io/Telethon/types/channel_admin_log_event_action.html
Admin Permissions
*****************
Giving or revoking admin permissions can be done with the `EditAdminRequest`__:
.. code-block:: python
from telethon.tl.functions.channels import EditAdminRequest
from telethon.tl.types import ChannelAdminRights
# You need both the channel and who to grant permissions
# They can either be channel/user or input channel/input user.
#
# ChannelAdminRights is a list of granted permissions.
# Set to True those you want to give.
rights = ChannelAdminRights(
post_messages=None,
add_admins=None,
invite_users=None,
change_info=True,
ban_users=None,
delete_messages=True,
pin_messages=True,
invite_link=None,
edit_messages=None
)
client(EditAdminRequest(channel, who, rights))
Thanks to `@Kyle2142`__ for `pointing out`__ that you **cannot** set
to ``True`` the ``post_messages`` and ``edit_messages`` fields. Those that
are ``None`` can be omitted (left here so you know `which are available`__.

Increasing View Count in a Channel
**********************************
It has been asked `quite`__ `a few`__ `times`__ (really, `many`__), and
while I don't understand why so many people ask this, the solution is to
use `GetMessagesViewsRequest`__, setting ``increment=True``:
.. code-block:: python
# Obtain `channel' through dialogs or through client.get_entity() or anyhow.
# Obtain `msg_ids' through `.get_message_history()` or anyhow. Must be a list.
client(GetMessagesViewsRequest(
peer=channel,
id=msg_ids,
increment=True
))

=====================
Working with messages
=====================
Forwarding messages
*******************
Note that ForwardMessageRequest_ (note it's Message, singular) will *not*
work if channels are involved. This is because channel (and megagroups) IDs
are not unique, so you also need to know who the sender is (a parameter this
request doesn't have).
Either way, you are encouraged to use ForwardMessagesRequest_ (note it's
Message*s*, plural) *always*, since it is more powerful, as follows:
.. code-block:: python
from telethon.tl.functions.messages import ForwardMessagesRequest
# note the s ^
messages = foo() # retrieve a few messages (or even one, in a list)
from_entity = bar()
to_entity = baz()
client(ForwardMessagesRequest(
from_peer=from_entity, # who sent these messages?
id=[msg.id for msg in messages], # which are the messages?
to_peer=to_entity # who are we forwarding them to?
))
The named arguments are there for clarity, although they're not needed because
they appear in order. You can obviously just wrap a single message on the list
too, if that's all you have.
Searching Messages
*******************
Messages are searched through the obvious SearchRequest_, but you may run
into issues_. A valid example would be:
.. code-block:: python
result = client(SearchRequest(
entity, 'query', InputMessagesFilterEmpty(), None, None, 0, 0, 100
))
It's important to note that the optional parameter ``from_id`` has been left
omitted and thus defaults to ``None``. Changing it to InputUserEmpty_, as one
could think to specify "no user", won't work because this parameter is a flag,
and it being unspecified has a different meaning.
If one were to set ``from_id=InputUserEmpty()``, it would filter messages
from "empty" senders, which would likely match no users.
If you get a ``ChatAdminRequiredError`` on a channel, it's probably because
you tried setting the ``from_id`` filter, and as the error says, you can't
do that. Leave it set to ``None`` and it should work.
As with every method, make sure you use the right ID/hash combination for
your ``InputUser`` or ``InputChat``, or you'll likely run into errors like
``UserIdInvalidError``.
Sending stickers
****************
Stickers are nothing else than ``files``, and when you successfully retrieve
the stickers for a certain sticker set, all you will have are ``handles`` to
these files. Remember, the files Telegram holds on their servers can be
referenced through this pair of ID/hash (unique per user), and you need to
use this handle when sending a "document" message. This working example will
send yourself the very first sticker you have:
.. code-block:: python
# Get all the sticker sets this user has
sticker_sets = client(GetAllStickersRequest(0))
# Choose a sticker set
sticker_set = sticker_sets.sets[0]
# Get the stickers for this sticker set
stickers = client(GetStickerSetRequest(
stickerset=InputStickerSetID(
id=sticker_set.id, access_hash=sticker_set.access_hash
)
))
# Stickers are nothing more than files, so send that
client(SendMediaRequest(
peer=client.get_me(),
media=InputMediaDocument(
id=InputDocument(
id=stickers.documents[0].id,
access_hash=stickers.documents[0].access_hash
),
caption=''
)
))
