Deeplinking into a telegram bot - telegram

Question

I have a simple use case. When a user clicks the link below,
T.me/MycompanynameBot?start=Microsoft
I want to show him 3 inline buttons corresponding to 3 Telegram channels within Microsoft. Is this possible?
The key is the bot must be able to retrieve the parameters from the URL.
Thank you.

Yes it's possible to retrieve bot parameter via answerCallbackQuery
Alternatively, the user can be redirected to the specified Game URL. For this option to work, you must first create a game for your bot via #Botfather and accept the terms. Otherwise, you may use links like:
t.me/your_bot?start=XXXX
that open your bot with a parameter.
Here is an example I made for you :
{
"ok": true,
"result": [{
"update_id": 89590932,
"message": {
"message_id": 5978,
"from": {
"id": 223110107,
"is_bot": false,
"first_name": "Ğąme",
"last_name": "Ǿver!",
"username": "GameO7er",
"language_code": "en"
},
"chat": {
"id": 223110107,
"first_name": "Ğąme",
"last_name": "Ǿver!",
"username": "GameO7er",
"type": "private"
},
"date": 1579094448,
"text": "/start Microsoft",
"entities": [{
"offset": 0,
"length": 6,
"type": "bot_command"
}]
}
}]
}
As you can see type=bot_command so you can parse the message if (type == "bot_command") and get text and substring /start from the original text or what ever you want to do.
In many cases I detect users with the parameters for example when I wanna to know who invited this user to bot I share the link in this format:
t.me/NameBot?start=ReferUserID
for example :
t.me/NameBot?start=223110107
is my ID and I can see how many user I've invited to the bot.
Hope be useful.
