A bot that takes enquiries, walks people through a game or a course, and accepts payment. Your clients can ask, choose and pay in Telegram.
The enquiry service on this site runs the same way: Bun, SQLite, straight to Telegram.
A person writes, you get a message. No admin panel to check.
Tested end to end, Telegram Stars included where they fit.
If your provider supports an integration, it gets wired into your site or bot.
Two lines and you are inside your own account, where the whole thing happens — the first screen, the price, the papers, the dialog.
