.. _sessions:
==============
Session Files
==============
The first parameter you pass the the constructor of the ``TelegramClient`` is
the ``session``, and defaults to be the session name (or full path). That is,
if you create a ``TelegramClient('anon')`` instance and connect, an
``anon.session`` file will be created on the working directory.
These database files using ``sqlite3`` contain the required information to
talk to the Telegram servers, such as to which IP the client should connect,
port, authorization key so that messages can be encrypted, and so on.
These files will by default also save all the input entities that you've seen,
so that you can get information about an user or channel by just their ID.
Telegram will **not** send their ``access_hash`` required to retrieve more
information about them, if it thinks you have already seem them. For this
reason, the library needs to store this information offline.
The library will by default too save all the entities (chats and channels
with their name and username, and users with the phone too) in the session
file, so that you can quickly access them by username or phone number.
If you're not going to work with updates, or don't need to cache the
``access_hash`` associated with the entities' ID, you can disable this
by setting ``client.session.save_entities = False``, or pass it as a
parameter to the ``TelegramClient``.
If you don't want to save the files as a database, you can also create
your custom ``Session`` subclass and override the ``.save()`` and ``.load()``
methods. For example, you could save it on a database:
.. code-block:: python
class DatabaseSession(Session):
def save():
# serialize relevant data to the database
def load():
# load relevant data to the database
You should read the ````session.py```` source file to know what "relevant
data" you need to keep track of.

Two Factor Authorization (2FA)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
If you have Two Factor Authorization (from now on, 2FA) enabled on your account, calling
:meth:`telethon.TelegramClient.sign_in` will raise a `SessionPasswordNeededError`.
When this happens, just :meth:`telethon.TelegramClient.sign_in` again with a ``password=``:

Users and Chats
=========================
.. note::
Make sure you have gone through :ref:`prelude` already!
.. contents::
:depth: 2
.. _retrieving-an-entity:
Retrieving an entity (user or group)
**************************************
An “entity” is used to refer to either an `User`__ or a `Chat`__
(which includes a `Channel`__). The most straightforward way to get
an entity is to use ``TelegramClient.get_entity()``. This method accepts
either a string, which can be a username, phone number or `t.me`__-like
link, or an integer that will be the ID of an **user**. You can use it
like so:
.. code-block:: python
# all of these work
lonami = client.get_entity('lonami')
lonami = client.get_entity('t.me/lonami')
lonami = client.get_entity('https://telegram.dog/lonami')
# other kind of entities
channel = client.get_entity('telegram.me/joinchat/AAAAAEkk2WdoDrB4-Q8-gg')
contact = client.get_entity('+34xxxxxxxxx')
friend = client.get_entity(friend_id)
For the last one to work, the library must have “seen” the user at least
once. The library will “see” the user as long as any request contains
them, so if youve called ``.get_dialogs()`` for instance, and your
friend was there, the library will know about them. For more, read about
the :ref:`sessions`.
If you want to get a channel or chat by ID, you need to specify that
they are a channel or a chat. The library cant infer what they are by
just their ID (unless the ID is marked, but this is only done
internally), so you need to wrap the ID around a `Peer`__ object:
.. code-block:: python
from telethon.tl.types import PeerUser, PeerChat, PeerChannel
my_user = client.get_entity(PeerUser(some_id))
my_chat = client.get_entity(PeerChat(some_id))
my_channel = client.get_entity(PeerChannel(some_id))
**Note** that most requests dont ask for an ``User``, or a ``Chat``,
but rather for ``InputUser``, ``InputChat``, and so on. If this is the
case, you should prefer ``.get_input_entity()`` over ``.get_entity()``,
as it will be immediate if you provide an ID (whereas ``.get_entity()``
may need to find who the entity is first).
Via your open “chats” (dialogs)
-------------------------------
.. note::
Please read here: :ref:`retrieving-all-dialogs`.
Via ResolveUsernameRequest
--------------------------
This is the request used by ``.get_entity`` internally, but you can also
use it by hand:
.. code-block:: python
from telethon.tl.functions.contacts import ResolveUsernameRequest
result = client(ResolveUsernameRequest('username'))
found_chats = result.chats
found_users = result.users
# result.peer may be a PeerUser, PeerChat or PeerChannel
See `Peer`__ for more information about this result.
Via MessageFwdHeader
--------------------
If all you have is a `MessageFwdHeader`__ after you retrieved a bunch
of messages, this gives you access to the ``from_id`` (if forwarded from
an user) and ``channel_id`` (if forwarded from a channel). Invoking
`GetMessagesRequest`__ also returns a list of ``chats`` and
``users``, and you can find the desired entity there:
.. code-block:: python
# Logic to retrieve messages with `GetMessagesRequest´
messages = foo()
fwd_header = bar()
user = next(u for u in messages.users if u.id == fwd_header.from_id)
channel = next(c for c in messages.chats if c.id == fwd_header.channel_id)
Or you can just call ``.get_entity()`` with the ID, as you should have
seen that user or channel before. A call to ``GetMessagesRequest`` may
still be neeed.
Via GetContactsRequest
----------------------
The library will call this for you if you pass a phone number to
``.get_entity``, but again, it can be done manually. If the user you
want to talk to is a contact, you can use `GetContactsRequest`__:
.. code-block:: python
from telethon.tl.functions.contacts import GetContactsRequest
from telethon.tl.types.contacts import Contacts
contacts = client(GetContactsRequest(0))
if isinstance(contacts, Contacts):
users = contacts.users
contacts = contacts.contacts

.. _retrieving-all-dialogs:
Retrieving all dialogs
***********************
There are several ``offset_xyz=`` parameters that have no effect at all,
but there's not much one can do since this is something the server should handle.
Currently, the only way to get all dialogs
(open chats, conversations, etc.) is by using the ``offset_date``:
.. code-block:: python
from telethon.tl.functions.messages import GetDialogsRequest
from telethon.tl.types import InputPeerEmpty
from time import sleep
dialogs = []
users = []
chats = []
last_date = None
chunk_size = 20
while True:
result = client(GetDialogsRequest(
offset_date=last_date,
offset_id=0,
offset_peer=InputPeerEmpty(),
limit=chunk_size
))
dialogs.extend(result.dialogs)
users.extend(result.users)
chats.extend(result.chats)
if not result.messages:
break
last_date = min(msg.date for msg in result.messages)
sleep(2)
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 <retrieving-an-entity>`
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 dont want to add yourself, maybe because youre 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 dont need to join but rather check whether its 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 youre 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)
# sleep(1) # This line seems to be optional, no guarantees!
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
youll get AdminLogResults.events in return which in turn has the final
`.action`__.

Increasing View Count in a Channel
****************************************
It has been asked `quite`__ `a few`__ `times`__ (really, `many`__), and
while I dont 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
))

Before reading any specific example, make sure to read the following common steps:
All the examples assume that you have successfully created a client and you're authorized as follows:
.. code-block:: python
from telethon import TelegramClient
# Use your own values here
api_id = 12345
api_hash = '0123456789abcdef0123456789abcdef'
phone_number = '+34600000000'
client = TelegramClient('some_name', api_id, api_hash)
client.connect() # Must return True, otherwise, try again
if not client.is_user_authorized():
client.send_code_request(phone_number)
# .sign_in() may raise PhoneNumberUnoccupiedError
# In that case, you need to call .sign_up() to get a new account
client.sign_in(phone_number, input('Enter code: '))
# The `client´ is now ready
Although Python will probably clean up the resources used by the ``TelegramClient``,
you should always ``.disconnect()`` it once you're done:
.. code-block:: python
try:
# Code using the client goes here
except:
# No matter what happens, always disconnect in the end
client.disconnect()
If the examples aren't enough, you're strongly advised to read the source code
for the InteractiveTelegramClient_ for an overview on how you could build your next script.
This example shows a basic usage more than enough in most cases. Even reading the source
for the TelegramClient_ may help a lot!

Users, Chats and Channels
=========================
Introduction
************
The library widely uses the concept of "entities". An entity will refer
to any ``User``, ``Chat`` or ``Channel`` object that the API may return
in response to certain methods, such as ``GetUsersRequest``.
To save bandwidth, the API also makes use of their "input" versions.
The input version of an entity (e.g. ``InputPeerUser``, ``InputChat``,
etc.) only contains the minimum required information that's required
for Telegram to be able to identify who you're referring to: their ID
and hash. This ID/hash pair is unique per user, so if you use the pair
given by another user **or bot** it will **not** work.
To save *even more* bandwidth, the API also makes use of the ``Peer``
versions, which just have an ID. This serves to identify them, but
peers alone are not enough to use them. You need to know their hash
before you can "use them".
Luckily, the library tries to simplify this mess the best it can.
Getting entities
****************
Through the use of the :ref:`sessions`, the library will automatically
remember the ID and hash pair, along with some extra information, so
you're able to just do this:
.. code-block:: python
# dialogs are the "conversations you have open"
# this method returns a list of Dialog, which
# have the .entity attribute and other information.
dialogs = client.get_dialogs(limit=200)
# all of these work and do the same
lonami = client.get_entity('lonami')
lonami = client.get_entity('t.me/lonami')
lonami = client.get_entity('https://telegram.dog/lonami')
# other kind of entities
channel = client.get_entity('telegram.me/joinchat/AAAAAEkk2WdoDrB4-Q8-gg')
contact = client.get_entity('+34xxxxxxxxx')
friend = client.get_entity(friend_id)
# using peers/input peers (note that the API may return these)
# users, chats and channels may all have the same ID, so it's
# necessary to wrap (at least) chat and channels inside Peer.
from telethon.tl.types import PeerUser, PeerChat, PeerChannel
my_user = client.get_entity(PeerUser(some_id))
my_chat = client.get_entity(PeerChat(some_id))
my_channel = client.get_entity(PeerChannel(some_id))
All methods in the :ref:`telegram-client` call ``.get_entity()`` to further
save you from the hassle of doing so manually, so doing things like
``client.send_message('lonami', 'hi!')`` is possible.
Every entity the library "sees" (in any response to any call) will by
default be cached in the ``.session`` file, to avoid performing
unnecessary API calls. If the entity cannot be found, some calls
like ``ResolveUsernameRequest`` or ``GetContactsRequest`` may be
made to obtain the required information.
Entities vs. Input Entities
***************************
As we mentioned before, API calls don't need to know the whole information
about the entities, only their ID and hash. For this reason, another method,
``.get_input_entity()`` is available. This will always use the cache while
possible, making zero API calls most of the time. When a request is made,
if you provided the full entity, e.g. an ``User``, the library will convert
it to the required ``InputPeer`` automatically for you.
**You should always favour ``.get_input_entity()``** over ``.get_entity()``
for this reason! Calling the latter will always make an API call to get
the most recent information about said entity, but invoking requests don't
need this information, just the ``InputPeer``. Only use ``.get_entity()``
if you need to get actual information, like the username, name, title, etc.
of the entity.

Sending Requests

Since we're working with Python, one must not forget that they can do ``help(client)`` or ``help(TelegramClient)``
at any time for a more detailed description and a list of all the available methods.
Calling ``help()`` from an interactive Python session will always list all the methods for any object, even yours!
Interacting with the Telegram API is done through sending **requests**,
this is, any "method" listed on the API. There are a few methods on the ``TelegramClient`` class
that abstract you from the need of manually importing the requests you need.
For instance, retrieving your own user can be done in a single line:
``myself = client.get_me()``
Internally, this method has sent a request to Telegram, who replied with the information about your own user.
If you want to retrieve any other user, chat or channel (channels are a special subset of chats),
you want to retrieve their "entity". This is how the library refers to either of these:

# It also accepts phone numbers, and will get the user
# from your contact list.

Session Files
==============
The first parameter you pass the constructor of the
``TelegramClient`` is the ``session``, and defaults to be the session
name (or full path). That is, if you create a ``TelegramClient('anon')``
instance and connect, an ``anon.session`` file will be created on the
working directory.
These JSON session files contain the required information to talk to the
Telegram servers, such as to which IP the client should connect, port,
authorization key so that messages can be encrypted, and so on.
These files will by default also save all the input entities that youve
seen, so that you can get information about an user or channel by just
their ID. Telegram will **not** send their ``access_hash`` required to
retrieve more information about them, if it thinks you have already seem
them. For this reason, the library needs to store this information
offline.
The library will by default too save all the entities (users with their
name, username, chats and so on) **in memory**, not to disk, so that you
can quickly access them by username or phone number. This can be
disabled too. Run ``help(client.session.entities)`` to see the available
methods (or ``help(EntityDatabase)``).
If youre not going to work without updates, or dont need to cache the
``access_hash`` associated with the entities ID, you can disable this
by setting ``client.session.save_entities = False``.
If you dont want to save the files as JSON, you can also create your
custom ``Session`` subclass and override the ``.save()`` and ``.load()``
methods. For example, you could save it on a database:
.. code-block:: python
class DatabaseSession(Session):
def save():
# serialize relevant data to the database
def load():
# load relevant data to the database
You should read the ``session.py`` source file to know what “relevant
data” you need to keep track of.

`RPC PWRTelegram <https://rpc.pwrtelegram.xyz/>`__, a public database
anyone can query, made by `Daniil <https://github.com/danog>`__. All the
information sent is a ``GET`` request with the error code, error message
and method used.
If you still would like to opt out, simply set
``client.session.report_errors = False`` to disable this feature, or
pass ``report_errors=False`` as a named parameter when creating a
``TelegramClient`` instance. However Daniil would really thank you if
you helped him (and everyone) by keeping it on!

Philosophy
==========
The intention of the library is to have an existing MTProto library
existing with hardly any dependencies (indeed, wherever Python is
available, you can run this library).
Being written in Python means that performance will be nowhere close to
other implementations written in, for instance, Java, C++, Rust, or
pretty much any other compiled language. However, the library turns out
to actually be pretty decent for common operations such as sending
messages, receiving updates, or other scripting. Uploading files may be
notably slower, but if you would like to contribute, pull requests are
appreciated!
If ``libssl`` is available on your system, the library will make use of
it to speed up some critical parts such as encrypting and decrypting the
messages. Files will notably be sent and downloaded faster.
The main focus is to keep everything clean and simple, for everyone to
understand how working with MTProto and Telegram works. Don't be afraid
to read the source, the code won't bite you! It may prove useful when
using the library on your own use cases.

=================
Project Structure
=================
Main interface
**************
The library itself is under the ``telethon/`` directory. The
``__init__.py`` file there exposes the main ``TelegramClient``, a class
that servers as a nice interface with the most commonly used methods on
Telegram such as sending messages, retrieving the message history,
handling updates, etc.
The ``TelegramClient`` inherits the ``TelegramBareClient``. The later is
basically a pruned version of the ``TelegramClient``, which knows basic
stuff like ``.invoke()``\ 'ing requests, downloading files, or switching
between data centers. This is primary to keep the method count per class
and file low and manageable.
Both clients make use of the ``network/mtproto_sender.py``. The
``MtProtoSender`` class handles packing requests with the ``salt``,
``id``, ``sequence``, etc., and also handles how to process responses
(i.e. pong, RPC errors). This class communicates through Telegram via
its ``.connection`` member.
The ``Connection`` class uses a ``extensions/tcp_client``, a C#-like
``TcpClient`` to ease working with sockets in Python. All the
``TcpClient`` know is how to connect through TCP and writing/reading
from the socket with optional cancel.
The ``Connection`` class bundles up all the connections modes and sends
and receives the messages accordingly (TCP full, obfuscated,
intermediate…).
Auto-generated code
*******************
The files under ``telethon_generator/`` are used to generate the code
that gets placed under ``telethon/tl/``. The ``TLGenerator`` takes in a
``.tl`` file, and spits out the generated classes which represent, as
Python classes, the request and types defined in the ``.tl`` file. It
also constructs an index so that they can be imported easily.

Telegram API in Other Languages
===============================
Telethon was made for **Python**, and as far as I know, there is no
*exact* port to other languages. However, there *are* other
implementations made by awesome people (one needs to be awesome to
understand the official Telegram documentation) on several languages
(even more Python too), listed below:
C
*
Possibly the most well-known unofficial open source implementation out
there by `**@vysheng** <https://github.com/vysheng>`__,
```tgl`` <https://github.com/vysheng/tgl>`__, and its console client
```telegram-cli`` <https://github.com/vysheng/tg>`__. Latest development
has been moved to `BitBucket <https://bitbucket.org/vysheng/tdcli>`__.
JavaScript
**********
`**@zerobias** <https://github.com/zerobias>`__ is working on
```telegram-mtproto`` <https://github.com/zerobias/telegram-mtproto>`__,
a work-in-progress JavaScript library installable via
```npm`` <https://www.npmjs.com/>`__.
Kotlin
******
`Kotlogram <https://github.com/badoualy/kotlogram>`__ is a Telegram
implementation written in Kotlin (the now
`official <https://blog.jetbrains.com/kotlin/2017/05/kotlin-on-android-now-official/>`__
language for
`Android <https://developer.android.com/kotlin/index.html>`__) by
`**@badoualy** <https://github.com/badoualy>`__, currently as a beta
yet working.
PHP
***
A PHP implementation is also available thanks to
`**@danog** <https://github.com/danog>`__ and his
`MadelineProto <https://github.com/danog/MadelineProto>`__ project, with
a very nice `online
documentation <https://daniil.it/MadelineProto/API_docs/>`__ too.
Python
******
A fairly new (as of the end of 2017) Telegram library written from the
ground up in Python by
`**@delivrance** <https://github.com/delivrance>`__ and his
`Pyrogram <https://github.com/pyrogram/pyrogram>`__ library! No hard
feelings Dan and good luck dealing with some of your users ;)
Rust
****
Yet another work-in-progress implementation, this time for Rust thanks
to `**@JuanPotato** <https://github.com/JuanPotato>`__ under the fancy
name of `Vail <https://github.com/JuanPotato/Vail>`__. This one is very
early still, but progress is being made at a steady rate.

Test Servers

To run Telethon on a test server, use the following code:
.. code-block:: python
client = TelegramClient(None, api_id, api_hash)
client.session.server_address = '149.154.167.40'
client.connect()
You can check your ``'test ip'`` on https://my.telegram.org.
You should set ``None`` session so to ensure you're generating a new
authorization key for it (it would fail if you used a session where you
had previously connected to another data center).
Once you're connected, you'll likely need to ``.sign_up()``. Remember
`anyone can access the phone you
choose <https://core.telegram.org/api/datacenter#testing-redirects>`__,
so don't store sensitive data here:
.. code-block:: python
from random import randint
dc_id = '2' # Change this to the DC id of the test server you chose
phone = '99966' + dc_id + str(randint(9999)).zfill(4)

Tips for Porting the Project
============================
If you're going to use the code on this repository to guide you, please
be kind and don't forget to mention it helped you!
You should start by reading the source code on the `first
release <https://github.com/LonamiWebs/Telethon/releases/tag/v0.1>`__ of
the project, and start creating a ``MtProtoSender``. Once this is made,
you should write by hand the code to authenticate on the Telegram's
server, which are some steps required to get the key required to talk to
them. Save it somewhere! Then, simply mimic, or reinvent other parts of
the code, and it will be ready to go within a few days.

Understanding the Type Language
===============================
`Telegram's Type Language <https://core.telegram.org/mtproto/TL>`__
(also known as TL, found on ``.tl`` files) is a concise way to define
what other programming languages commonly call classes or structs.
Every definition is written as follows for a Telegram object is defined
as follows:
.. code:: tl
name#id argument_name:argument_type = CommonType
This means that in a single line you know what the ``TLObject`` name is.
You know it's unique ID, and you know what arguments it has. It really
isn't that hard to write a generator for generating code to any
platform!
The generated code should also be able to *encode* the ``TLObject`` (let
this be a request or a type) into bytes, so they can be sent over the
network. This isn't a big deal either, because you know how the
``TLObject``\ 's are made, and how the types should be serialized.
You can either write your own code generator, or use the one this
library provides, but please be kind and keep some special mention to
this project for helping you out.
This is only a introduction. The ``TL`` language is not *that* easy. But
it's not that hard either. You're free to sniff the
``telethon_generator/`` files and learn how to parse other more complex
lines, such as ``flags`` (to indicate things that may or may not be
written at all) and ``vector``\ 's.

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.

__ https://github.com/LonamiWebs/Telethon/wiki/Joining-a-chat-or-channel#joining-a-private-chat-or-channel
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.)

__ https://lonamiwebs.github.io/Telethon/methods/channels/get_participants.html

__ https://lonamiwebs.github.io/Telethon/constructors/channel_participants_search.html
__ https://lonamiwebs.github.io/Telethon/constructors/channels/channel_participants.html
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/methods/channels/get_admin_log.html
__ 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
))

Forwarding messages

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).

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.

If you have indeed read the wiki, and have tried looking for the method,
and yet you didn't find what you need, **that's fine**. Telegram's API
can have some obscure names at times, and for this reason, there is a
`"question"
label <https://github.com/LonamiWebs/Telethon/issues?utf8=%E2%9C%93&q=is%3Aissue%20is%3Aclosed%20label%3Aquestion%20>`__
with questions that are okay to ask. Just state what you've tried so
that we know you've made an effort, or you'll go to the Wall of Shame.
Of course, if the issue you're going to open is not even a question but
a real issue with the library (thankfully, most of the issues have been
that!), you won't end up here. Don't worry.
