============
Deep Linking
============
Telegram bots have a deep linking mechanism, that allows for passing
additional parameters to the bot on startup. It could be a command that
launches the bot — or an auth token to connect the user's Telegram
account to their account on some external service.
You can read detailed description in the source:
https://core.telegram.org/bots/features#deep-linking
We have added some utils to get deep links more handy.
Examples
========
Basic link example
------------------
.. code-block:: python
from aiogram.utils.deep_linking import create_start_link
link = await create_start_link(bot, 'foo')
# result: 'https://t.me/MyBot?start=foo'
Encoded link
------------
.. code-block:: python
from aiogram.utils.deep_linking import create_start_link
link = await create_start_link(bot, 'foo', encode=True)
# result: 'https://t.me/MyBot?start=Zm9v'
Decode it back
--------------
.. code-block:: python
from aiogram.utils.deep_linking import decode_payload
from aiogram.filters import CommandStart, CommandObject
from aiogram.types import Message
@router.message(CommandStart(deep_link=True))
async def handler(message: Message, command: CommandObject):
args = command.args
payload = decode_payload(args)
await message.answer(f"Your payload: {payload}")
