Deep Linking - pass any params on Bot starting

You can pass any params on bot starting to BJS with link:

http://t.me/BOT_NAME?start=PARAMS

In BJS command /start:

Bot.sendMessage(params);

For example:

http://t.me/botsbusinessadminbot?start=API_TOKEN

We pass user's API Token to bot.

let api_token = params;
// do anything what you want with this params
Bot.sendMessage("Your api token is: " + api_token)
