#For creating and getting API keys have a look at here: https://core.telegram.org/bots#3-how-do-i-create-a-bot
#TL;DR Basically visit @botfather in telegram and create a bot, get it's API TOKEN. then we need chat id, type your bot username and send it a message, then visit this url with your token: https://api.telegram.org/bot[YOUR_BOT_API_TOKEN]/getUpdates you will find your message object, take the id under chat, this is your chat_id.
