# This example shows how to implement deep linking (https://core.telegram.org/bots#deep-linking)
|
|
# with the pyTelegramBotAPI.
|
|
# Note: This is not a working, production-ready sample.
|
|
#
|
|
# In this example we are connecting a user account on a website with a Telegram bot.
|
|
# Implementing this will enable you to push notifications (and other content) to your users' Telegram account.
|
|
# In this explanation the word 'database' can refer to any form of key-value storage.
|
|
# The deep linking explained:
|
|
#
|
|
# 1. Let the user log in on an actual website with actual username-password authentication.
|
|
#
|
|
# 2. Generate a unique hashcode (we will call it unique_code)
|
|
#
|
|
# 3. Save unique_code->username to the database.
|
|
#
|
|
# 4. Show the user the URL https://telegram.me/YOURBOTNAME?start=unique_code
|
|
#
|
|
# 5. Now as soon as the user opens this URL in Telegram and presses 'Start',
|
|
# your bot will receive a text message containing '/start unique_code',
|
|
# where unique_code is of course replaced by the actual hashcode.
|
|
#
|
|
# 6. Let the bot retrieve the username by querying the database for unique_code.
|
|
#
|
|
# 7. Save chat_id->username to the database.
|
|
#
|
|
# 8. Now when your bot receives another message, it can query message.chat.id in the database
|
|
# to check if the message is from this specific user. (And handle accordingly) or
|
|
# you can push messages to the user using his chat id.
|
|
#
|
|
# Steps 1 to 4 will have to be implemented in a web server, using a language such as PHP, Python, C# or Java. These
|
|
# steps are not shown here. Only steps 5 to 7 are illustrated, some in pseudo-code, with this example.
