FAQ
What do I need to get started?
You will need a clear idea/specification of your app and a Telegram Bot Token created via @BotFather. If you don't have a bot token yet, I can guide you through the process.
How is user data and authentication handled in Telegram Mini Apps?
I implement secure Telegram WebApp initData validation on the backend. This guarantees that user IDs, usernames, and session data are cryptographically verified and cannot be spoofed.
Can you connect the Mini App to an external database and backend?
Yes, in the Standard and Premium packages, I build complete backends (Node.js/Go) connected to PostgreSQL/Supabase databases to store user progress, orders, or profile data.
Where will the Mini App be hosted?
The frontend is typically deployed on Vercel or modern cloud providers with SSL (HTTPS is strictly required by Telegram). I can set up deployment on your hosting of choice.
