Working with messages Working with messages
===================== =====================

These examples assume you have read :ref:`full-api`. These examples assume you have read :ref:`full-api`.

features arrive and the API changes. Please refer to the linked page to learn how
to send spoilers, custom emoji, stickers, react to messages, and more things.

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
from telethon.tl.functions.messages import GetAllStickersRequest
sticker_sets = await client(GetAllStickersRequest(0))
# Choose a sticker set
from telethon.tl.functions.messages import GetStickerSetRequest
from telethon.tl.types import InputStickerSetID
sticker_set = sticker_sets.sets[0]
# Get the stickers for this sticker set
stickers = await client(GetStickerSetRequest(
stickerset=InputStickerSetID(
id=sticker_set.id, access_hash=sticker_set.access_hash
),
hash=0
))
# Stickers are nothing more than files, so send that
await client.send_file('me', stickers.documents[0])
Sending reactions
=================
It works very similar to replying to a message. You need to specify the chat,
message ID you wish to react to, and reaction, using :tl:`SendReaction`:
.. code-block:: python
from telethon.tl.functions.messages import SendReactionRequest
await client(SendReactionRequest(
peer=chat,
msg_id=42,
reaction='❤️'
))
Note that you cannot use strings like ``:heart:`` for the reaction. You must
use the desired emoji directly. You can most easily achieve this by
copy-pasting the emoji from an official application such as Telegram Desktop.
If for some reason you cannot embed emoji directly into the code, you can also
use its unicode escape (which you can find using websites like
`unicode-table.com`_), or install a different package, like `emoji`_:
.. code-block:: python
# All of these work exactly the same (you only need one):
import emoji
reaction = emoji.emojize(':red_heart:')
reaction = '❤️'
reaction = '\u2764'
from telethon.tl.functions.messages import SendReactionRequest
await client(SendReactionRequest(
peer=chat,
msg_id=42,
reaction=reaction
))
Please make sure to check the help pages of the respective websites you use
if you need a more in-depth explanation on how they work. Telethon only needs
you to provide the emoji in some form. Some packages or websites can make this
easier.
Sending spoilers (hidden text)
==============================
The current markdown and HTML parsers do not offer a way to send spoilers yet.
You need to use :tl:`MessageEntitySpoiler` so that parts of the message text
are shown under a spoiler.
The simplest way to do this is to `modify the builtin parsers`_ to support
sending these new message entities with the features they already provide.
Sending custom emoji
====================
The current markdown and HTML parsers do not offer a way to send custom emoji
yet. You need to use :tl:`MessageEntityCustomEmoji` so that parts of the
message text with emoji are replaced with a custom one instead.
The simplest way to do this is to `modify the builtin parsers`_ to support
sending these new message entities with the features they already provide.
:tl:`MessageEntityCustomEmoji` must wrap an emoji in order to work (you can't
put it around arbitrary ``"text"``, it won't work), so be sure to keep this in
mind when using it.
To find the ``document_id`` for the custom emoji, the simplest way is to send
a message with an official client containing the custom emoji you want, and
then print the ``message.entities`` to find the ``document_id``.
If you prefer, you can also use :tl:`GetFeaturedEmojiStickers` to find about
the ``document_id`` of featured custom emoji.
