Chatbot for Telegram crypto airdrop

We're looking to develop a Telegram bot to be able to create referral campaigns for Telegram groups. The goal of this bot is to allow anyone interested to invite friends in a Telegram group and get a unique referral URL for such. The bot would keep track of which users join under each participant and also provide a function for updating the participant's crypto address for them to receive rewards. The first thing the bot should do when started would be to send a customized message. The bot would then keep providing users with those 4 functions, and give them dedicated information based on which one they chose each time. GROUP: Respond with a link to the relevant group. LINK: Respond by providing a unique referral linking back to the bot. Users will be able to refer users by sharing it. ADDRESS: Show users their ETH address. If they haven't set it ask for one and allow updating STATS: Show stats for each referral. Like: users referred, points inured etc. Points will be rewarded for a) joining and b) referrals that join. Information with each user's address, telegram username, and users that have been referred under him should be stored with the potential to be exported in a workable format. Example for such bot: [login to view URL] Optional bonus: If you can integrate the bot to keep track of results in a readable google spreadsheet.
